Abstract:
The entomological inventory survey results of super-family Coccoidea in four Arboretum parks - Upper, Lower, Coastal and Montedor - are presented, the predominate species, the distributional pattern and food chains have been found. Four basic coccid groups have been specified according to the pattern of distribution on plants and the food chains. The coccid species composition in the Arboretum is presented by 19 phytophagan species out of 6 families. In all the parks the representatives of the family Coccidae dominate outman and injuriousness. Two coccid species Parthenolecanium corni Bouché. and Parthenolecanium pomeranicum Kaw. are the new ones for the coccid fauna of the Nikitsky Botanical Gardens. The coccid fauna and its food chains were studied present with the decorative cultivars guided by visual analysis of leaves, tree trunks and boughs. The determined coccids coupled with a part of a forage plant were looked through by means the binocular. The trivial belonging was defined according to N.S. Borhsenius method [1]. The distribution and forage plants occupancy rating was determined by 4 - scorecard scale: 0 ̶ crop pest is not detected; 1 ̶ sporadical plant invasion; 2 ̶ is present often but in small amounts; 3 ̶ mass plants occupancy [4]. The elicited coccid species were divided into polyphagans (P), monophagans (M) and oligophagans (O). As the result of entomological coccid fauna inventory survey in the Arboretum of the Nikitsky Botanical Gardens 19 species, which are of six families, were found. Families Diaspididae and Coccidae are the most numerous. The richest species diversity appears in Lower Arboretum park. According to food chains character 8 monophagans, 1 oligophagan and 10 polyphagans have been found. According to the coccid distribution on plants there are 4 groups: the first group includes coccids, which are inhabitants of evergreen shrubbery; the second one occupies leaves and young off-shoots; the third one settles by colonies on tree trunks, skeletal boughs or by rogue specimens; the fourth coccid group is confined to roots. Two new coccid species - Parthenolecanium pomeranicum Kaw. ̶ on common yew and Parthenolecanium corni Bouché. ̶ on high cranberry in the territory of the Arboretum have been found.

Abstract:
Myrmecophytic species of the Paleotropical plant genus Macaranga (Euphorbiaceae) have hollow stems that are almost always occupied by ants of the genus Crematogaster and scale insects of the family Coccidae (Hemiptera: Coccoidea). The coccids have a cryptic endophytic lifestyle and are confined to this microhabitat. They are much more diverse than previously recognised. First data are presented on the diversity, prevalence, specificity and distribution of the coccids associated with myrmecophytic Macaranga species. Twenty-two species of Coccidae in total, including 15 previously unknown from Macaranga, were discovered from 19 species of Macaranga in Peninsular Malaysia and Borneo. The original describers tentatively assigned the known coccid species to Coccus (Coccinae) but the Macaranga coccids still require taxonomic research to establish their correct placing. The coccids varied in their host-plant specificity from species that occurred in most of the sampled Macaranga to one species that was found almost exclusively only on a single host species. In addition to their occurrence on Macaranga, only three species, C. macarangae and C. secretus and morphospecies C. 214 were found on rare occasions in the stem interior of a few other myrmecophytes and in a non-myrmecophytic liana, but did not regularly colonise these plants. Most of the coccids can be regarded as highly specific at the plant genus level.

Abstract:
The interactions between insect herbivores and their hosts are among the most fundamental biological associations. Although there are many data available on the host associations of scale insects, there have been few attempts to synthesize the available information. Here we examine host associations of Coccidae, the third most species-rich family of scale insects. We compare host-plant data for most species of coccids that were available from online databases, especially ScaleNet, and the literature, with species richness estimates for host-plant families. Similar to most insect groups, coccids showed high host specialization with about 64% of species recorded from only a single plant family. Analysis of the relationship between species richness of host-plant families and the number of species of coccids recorded on these plants showed a significant positive correlation between host-plant species richness per angiosperm plant family and coccid species richness (P < 0.0001). This is expected under a null model in which host use is randomly distributed across families according to plant species richness of the families. However, the presence of several exceptions (Orchidaceae and Asteraceae in particular) warns that host associations in coccids might be more complex than the correlation analysis suggests.

Abstract:
ABSTRACTMonensin is a polyether ionophore antibiotic that is widely used in the control of coccidia in animals. Despite its significance in veterinary medicine, little is known about its mode of action and potential mechanisms of resistance in coccidian parasites. Here we show that monensin causes accumulation of the coccidianToxoplasma gondiiat an apparent late-S-phase cell cycle checkpoint. In addition, experiments utilizing a monensin-resistantT. gondiimutant show that this effect of monensin is dependent on the function of a mitochondrial homologue of the MutS DNA damage repair enzyme (TgMSH-1). Furthermore, the same TgMSH-1-dependent cell cycle disruption is observed with the antiparasitic ionophore salinomycin and the DNA alkylating agent methyl nitrosourea. Our results suggest a novel mechanism for the mode of action of monensin and salinomycin on coccidial parasites, in which the drug activates an MSH-1-dependent cell cycle checkpoint by an unknown mechanism, ultimately leading to the death of the parasite. This model would indicate that cell cycle disruption is an important mediator of drug susceptibility and resistance to ionophoric antibiotics in coccidian parasites.

Abstract:
Hepatic coccidiosis, usually caused by a member of the genus Eimeria, is common in rabbits but rare in other mammals. We describe the first reported case of naturally occurring hepatic coccidiosis in a goat. An approximately 6-month-old crossbred goat was presented with a history of diarrhea for 1 week and death. The liver had grossly visible, coalescing foci of necrosis measuring up to 6 cm in greatest dimension. Microscopically, areas of coagulative necrosis also had ectatic and hyperplastic bile ducts that contained coccidial meronts, macrogamonts, and microgamonts within the cytoplasm of epithelial cells. Bile duct lumina contained scattered oocysts. Fibrosis and aggregates of lymphocytes surrounded affected ducts. Microscopic and ultrastructural characteristics of coccidian stages were compatible with the genus Eimeria, but the species could not be determined. The small intestine also had coccidios])L however, it was unclear whether or not the same coccidian species affected both the liver and the intestine.

Abstract:
ABSTRACT The viability of the coccoid forms of Helicobacter pylori was evaluated by assessing protein synthesis. Metabolic labeling studies showed the synthesis of proteins and the specific protein profiles of H. pylori coccoids produced under various conditions. Harsh conditions such as aerobiosis and starvation (lack of horse serum) in the culture did not affect the synthesis of proteins in the coccoids. Lowering of the pH to that of gastric secretions induced expression of several proteins in the coccoids. However, the coccoids produced under prolonged microaerobic conditions exhibited a profile of acid stress-induced protein expression different from that induced by aerobiosis or starvation. Our data suggest that coccoid H. pylori exhibits diversity in viability following exposure to different stresses and that the response to acid stress of coccoid H. pylori could be involved in infection of the host stomach.

Abstract:
Coccids are amongst the most destructive pests of horticultural, agricultural, household ornamental plants, and wild plants in varying degrees. To evaluate the prevalence of its fauna in Jahangirnagar University Campus (JUC), Savar, Dhaka, Bangladesh, a year-long study was conducted from September 2004 to August 2005, by visual counting in regular fortnightly visits. A total of 99755 insects of 13 coccid species were recorded from 12 study sites. They infested 41.2% plants of 786 individuals under 17 host plant species. Coccid incidence varied greatly according to seasons, plant numbers, and study sites. Significant differences were observed in the mean number of coccid fauna (F = 3.87, df = 12, P < 0.05) in different study sites. The highest infestation was observed by Ferrisia virgata followed by Chloropulvinaria pisdii, Planococcus pacificus, Perissopneumon ferox, Icerya aegyptiaca, Aspidiotus destructor, Crypticerya jacobsoni, Icerya minor, Rastrococcus spinosus, Pseudococcus citriculus, Maconellicoccus hirsutus, Cerococcus indicus, and Coccus hesperidum. The total number of plants present in the study sites was positively correlated with the total infested plants (r = 0.451). Highly infested plants attracted more insects than less infested plants (r = 0.813). The coccid population started to increase after the winter season and maintained a steady level up to the end of the rainy season (March to August). All study sites contained insect populations but SS-6, 7, 8, and 10 harbored significantly higher numbers of them. Rain did not make any significant differences (F = 1.445, df = 11, P = 0.168) in the pest infestation. The mean number of coccids at different months was positively correlated with the monthly average temperature (r = 0.390) and relative humidity (r = 0.412). The present findings may help in designing an integrated coccid management system. Bangladesh J. Zool. 50 (1): 67-82, 2022

Abstract:
The Coccidia are a subclass of the Apicomplexa and include several genera of protozoan parasites that cause important diseases in humans and animals, with Toxoplasma gondii becoming the ‘model organism’ for research into the coccidian molecular and cellular processes. The amenability to the cultivation of T. gondii tachyzoites and the wide availability of molecular tools for this parasite have revealed many mechanisms related to their cellular trafficking and roles of parasite secretory organelles, which are critical in parasite-host interaction. Nevertheless, the extrapolation of the T. gondii mechanisms described in tachyzoites to other coccidian parasites should be done carefully. In this review, we considered published data from Eimeria parasites, a coccidian genus comprising thousands of species whose infections have important consequences in livestock and poultry. These studies suggest that the Coccidia possess both shared and diversified mechanisms of protein trafficking and secretion potentially linked to their lifecycles. Whereas trafficking and secretion appear to be well conversed prior to and during host-cell invasion, important differences emerge once endogenous development commences. Therefore, further studies to validate the mechanisms described in T. gondii tachyzoites should be performed across a broader range of coccidians (including T. gondii sporozoites). In addition, further genus-specific research regarding important disease-causing Coccidia is needed to unveil the individual molecular mechanisms of pathogenesis related to their specific lifecycles and hosts.

SUMMARYBefore the discovery of Toxoplasma gondii as a coccidium of the cat in 1970, cat and dog coccidia were classified in the genus Isospora and considered of little clinical or zoonotic significance. Since 1970, several new (Hammondia sp., Neospora sp.) and previously described species, including Sarcocystis, Besnoitia, and Cryptosporidium have been found as coccidians of cats and dogs with clinical and zoonotic significance. In the present paper I review salient features of the evolution of cat and dog coccidia.

Abstract:
Se ha desarrollado un sistema innovador de cocción de alimentos basado en el calentamiento por radiación infrarroja (IR) mediante un láser de CO2 (IR Láser CO2) teniendo en cuenta que el agua posee una elevada capacidad de absorción electromagnética en la longitud de onda del IR Láser CO2. El sistema de cocción se ha adaptado en una impresora 3D de alimentos y se ha diseñado con los siguientes requerimientos: 1) cocción en un área delimitada; 2) capacidad de control de la temperatura de cocción; 3) las dimensiones físicas de la lámpara de CO2 deben adaptarse a la impresora 3D de alimentos; 4) el consumo de energía debe ser compatible con la capacidad de la impresora 3D de alimentos; 5) el sistema debe ser controlado por software; 6) versatilidad para cocinar mientras se imprime el alimento o después de la impresión. En el presente estudio se han usado dos sistemas de cocción por IR Láser CO2. Primero se usó una grabadora y cortadora con IR Láser CO2 en la que se establecieron unas condiciones específicas que permitieron la cocción de hamburguesas de ternera, puré de patatas y masas de pizza. Después se desarrolló un nuevo sistema de cocción integrado en la impresora 3D de alimentos formado por una lámpara láser de CO2, un sistema de galvos para dirigir el haz láser a la zona de cocción y un software que permitía controlar la posición y frecuencia del movimiento de los galvanómetros. Con este nuevo sistema se podía cocinar de manera homogénea un área determinada, debido al rápido movimiento de los espejos de los galvos. Se cocinaron los siguientes alimentos en el interior de la impresora 3D de alimentos: hamburguesas de carne de ternera; preparados vegetales tipo hamburguesas formuladas con legumbres, hortalizas y huevo como ingredientes principales; y bases de pizza. Para demostrar que la cocción fue adecuada y suficiente, la cocción mediante IR Láser CO2 se comparó con diferentes sistemas de cocción tradicionales (plancha, barbacoa y hornos IR, de convección, de suela refractaria y microondas) y se evaluaron las características microbiológicas, físico-químicas y sensoriales de los alimentos cocidos. Se analizó la formación de hidrocarburos aromáticos policíclicos con el fin de evaluar la seguridad toxicológica, y se estudió el efecto térmico en la eliminación de Salmonella Typhimurium, Salmonella Senftenberg y Escherichia coli O157:H7 inoculadas en las hamburguesas de ternera y en los preparados vegetales. Los análisis microbiológicos y toxicológicos demostraron que los alimentos cocinados con el nuevo sistema IR Láser CO2 son tan seguros como los cocinados con los métodos convencionales. Los análisis sensoriales indicaron que la preferencia de los consumidores 12 por los alimentos cocidos con IR Láser CO2 fue igual o superior a la preferencia por los alimentos cocidos con los sistemas convencionales. Además, se desarrolló un modelo numérico basado en la dinámica computacional de fluidos para simular el proceso de cocción de las hamburguesas de ternera y los preparados vegetales y se validó con los resultados experimentales de aumento de temperatura durante el proceso de cocción. Los resultados numéricos de la evolución de la temperatura coincidieron con los datos experimentales, excepto durante los primeros minutos de la cocción. El modelo de simulación numérico se considera una potente herramienta para optimizar el proceso de cocción del sistema IR Láser CO2. A partir de los resultados obtenidos se abren nuevas vías de trabajo, que incluyen estudios de cocción con alimentos de composición sensiblemente diferente a los probados hasta el momento; la simulación del proceso de cocción con diferentes parámetros y estrategias de cocción; y la realización de estudios nutricionales.<br>An innovative cooking system based on infrared radiation (IR) using a CO2 laser (CO2 IR Laser) has been developed considering that water absorbance of electromagnetic infrared radiation at CO2 laser wavelength is very high. The new cooking system has been adapted into a 3D food printer and has been designed with the following requirements: 1) ability to cook in a delimited area; 2) control of the cooking temperature; 3) physical dimensions that fit inside the 3D Food Printer; 4) energy consumption below the power supply limits; 5) software-controlled system; 6) versatility to cook while printing the food or to cook once the food is printed. In the present study, two CO2 IR Laser cooking systems have been used and tested. The first CO2 IR Laser cooking system studied was a laser engraver and cutter equipment in which specific conditions were applied to cook beef burgers, mashed potatoes bites and pizza dough. After, a new cooking system adapted to the 3D food printer was developed, consisting of a CO2 laser lamp, a system of galvo mirrors that direct the laser beam to the cooking area, and a software that allowed controlling the position and the frequency of movement of galvanometers. With this new system, a chosen area could be homogenously cooked, due to the rapid movement of the galvo mirrors. The food products cooked inside the 3D food printer were: beef burgers; vegetarian patties prepared with legumes, vegetables and egg as main ingredients; and pizza dough. To demonstrate that cooking had been achieved, food products were cooked with the CO2 IR laser systems and different traditional cooking systems (flat and barbeque grills; IR, convection, desk and microwave ovens). Microbiological, physico-chemical and sensory characteristics of the cooked foods were evaluated. The formation of polycyclic aromatic hydrocarbons was analyzed in beef burgers and pizzas to evaluate toxicological safety, and the thermal effect in the count reduction or survival of Salmonella Typhimurium, Salmonella Senftenberg and Escherichia coli O157:H7 inoculated in beef burgers and vegetarian patties was studied. Microbiological and toxicological analyses showed that food products cooked with the new CO2 IR Laser system were as safe as food cooked with traditional methods. Sensory analyses showed that consumers had the same, or even higher, level of preference for foods cooked with CO2 IR laser system in comparison with foods cooked with traditional methods. In addition, a numerical model based on computational fluid dynamics was developed to simulate the cooking process of beef burgers and vegetarian patties, and it was validated with experimental data of temperature evolution during the cooking process. The numerical results for temperature evolution given by the model coincide with the experimental data, except for the first minutes of cooking. The numerical simulation model is a powerful tool to optimize the cooking process of the CO2 IR Laser system. Based on the results obtained, future work will be carried out including cooking experimental studies with foods containing a significantly different composition; the simulation of the cooking process with different parametric conditions; and nutritional studies.

Abstract:
Between February 1986 and October 1988, 863 amphibians and reptiles were collected in northcentral Texas and examined for coccidial parasites. Thirteen percent of amphibians <26% salamanders, 11% frogs and toads) and 28% of reptiles (54% turtles, 25% snakes) harbored 20 previously described and 16 new species of coccidia; overall prevalence of infection was 176/863 < 20%). Sixteen Ambvstoma texanum were infected with Eimeria ambystomae which represents new host and geographic locality records for the coccidium. Forty anurans were found to be passing coccidia, including Pseudacris streckeri. Bufo valliceos and Gastrophryne olivacea. Four new species of coccidia were described from anurans and include Eimeria flexuosa. E. streckeri. Isospora dellcatus and I_. fraaosum. However, oocysts found in B. v.. valliceps were determined experimentally to represent pseudoparasites. Sixty-eight turtles were infected with coccidia, including Chelvdra serpentina, Kinoeternon flavescens. Pseudemvs texana. Terrapeng ornata and Trachemvs scripta eleoans. Fourteen eimerians (5 of which are described as new species) were found in turtles. The new species from turtles include Eimeria cooteri, E. ornata, E. Btvlosa. E. texana and E. trachemvdis. Interestingly, all 96 lizards examined were negative for coccidia. Fifty-three snakes including 11 colubrids and 1 viperld harbored coccidia of the genera Caryospora. Cryptosporidium. Eimeria and Sarcocystis: prevalence of infection was highest in 3 species of North American water snakes <Nerodia spp.). Seven new species of Eimeria were described from snakes, including E. conanti. E. lnfirmus. E. papillosum. E. rhombifera. E. serpenticola. E. striatula and E. tenuis. There was no preference for coccidia between the sexes of any hosts. Based on limited data from a single anuran host, prevalence was higher during wetter months of spring than in summer. In addition, prevalence was higher in aquatic and semiaquatic snakes than in truly terrestrial species. Preliminary data suggested that using host specificity data of coccidia may be a method of studying host phylogeny and coevolutionary relationships in thamnophiine snakes.

Abstract:
In this project I have undertaken an analysis of the enzymes and pathways of energy metabolism in Eimeria, with a particular view to determining how it is affected by, and adapted towards, the different environmental conditions encountered during its life cycle. The study has been dominated by two main approaches: characterisation of glycolytic enzymes, and analysis of end-products. In some areas it has been possible to carry out comparative studies using the related coccidial species Cryptosporidium parvum and Toxoplasma gondii. The activities of selected enzymes of energy metabolism were measured in an attempt to determine which pathways of energy metabolism were present in the parasites, and to asses their relative significance in different species and stages. Eimeria, Toxoplasma and Cryptosporidium all contained high levels of the glycolytic enzymes phosphofructokinase and pyruvate kinase, as well as lactate dehydrogenase. The TCA-specific enzyme succinate dehydrogenase could not be detected in Eimeria or Cryptosporidium but was present in tachyzoites of T. gondii. T. gondii and E. tenella contained an NADP+-specific isocitrate dehydrogenase but no NAD+-dependent enzyme; C. parvum contained neither isocitrate dehydrogenase variety. The activities of pyruvate kinase and lactate dehydrogenase were significantly higher in bradyzoites than in tachyzoites of T. gondii, suggesting that the former may be more reliant on fermentative modes of energy generation. In E. tenella, the enzyme activities investigated were generally much lower in sporulated than in unsporulated oocysts, probably reflecting the dormant nature of the latter. Sporozoites contained high levels of most enzymes indicating that significant activation or synthesis of enzymes occurs during, or shortly after, excystation.

Abstract:
A series of experiments were conducted to evaluate the effects of dietary enzyme supplementation in broilers exposed to a live coccidia oocyst vaccine. In each experiment, Cobb 500 broilers were obtained at day of hatch from a commercial hatchery. Half of the chicks were sprayed with Coccivac BTM and housed in battery brooders in experiment (EXP) 1 and 2 or floor pens (EXP 3). Experimental diets were formulated according to Cobb 500 nutrient recommendations (positive control; PC) with the exception of Ca and available P (aP), which were reduced in the negative control (NC) diets approximately 0.1% (EXP 1), 0.11 and 0.13%, respectively (EXP 2), and 0.13% (EXP 3). Negative control diets in EXP 1 were supplemented with phytase (PHY), protease (PRO), xylanase (XYL), and the combination of PHY+PRO, PHY+XYL, and PHY+PRO+XYL. Negative control diets in EXP 2 were supplemented with PHY A, PHY B, and PHY C. In EXP 3, PC diets were supplemented with PHY at 1000 FTU/kg, and NC diets were supplemented with PHY at 1000 or 5000 FTU/kg. In all three experiments PHY supplementation generally improved (P â ¤ 0.05) broiler performance and bone ash. Vaccination reduced (P â ¤ 0.05) broiler performance in EXP 1 and 3, but increased (P â ¤ 0.05) broiler performance in EXP 2. Xylanase and/or PHY supplementation tended to improve (P = 0.10) ileal amino acid digestibility (IAAD) in vaccinated broilers in EXP 1 and EXP 3. Phytase supplementation improved (P â ¤ 0.05) IAAD and vaccination reduced (P â ¤ 0.05) IAAD in EXP 3. Small intestinal morphology and goblet cell numbers were affected by enzyme supplementation and vaccination, which resulted in significant (P â ¤ 0.05) interactions. In general, vaccination increased (P â ¤ 0.05) small intestinal crypt depth and reduced (P â ¤ 0.05) goblet cell numbers in EXP 3. Phytase supplementation of the NC diets fed to vaccinated broilers ameliorated the reduction in ileal goblet cells associated with vaccination (EXP 3). Enzyme supplementation tended to improve nutrient digestibility and altered small intestinal morphology in vaccinated broilers. Vaccination reduced broiler performance but nutrient digestion and dietary enzymes may improve nutrient utilization during a coccidia vaccination.<br>Ph. D.

Abstract:
Coccidiosis, ubiquitous diseases of poultry, seriously impair the growth and feed utilization of livestock and poultry. Coccidiosis causes over $600 million annual losses world-wide and no vaccine is currently available. The goal of this study was to investigate the cellular and molecular mechanisms controlling protective immune responses to coccidia parasites in order to develop immunological control strategy against coccidiosis. The major findings of this study were: 1) cell-mediated immunity plays a major role in protection against coccidiosis, 2) when different genetic lines showing different levels of disease susceptibility were compared, higher T-cell response was seen in the strains of chickens showing higher disease resistance, 3) early interferon secretion was observed in more coccidia-resistant chicken strains, 4) both sporozoite and merozoite antigens were able to induce interferon production, and 5) chicken monoclonal antibodies which detect immunogenic coccidia proteins have been developed. This study provided a good background work for future studies toward the development of recombinant coccidial vaccine. Availability of chicken monoclonal antibodies which detect immunogenic coccidia proteins will enhance our ability to identify potential coccidial vaccine antigens.

Full text
Abstract:
Within the project "Pathogenic Streptococcus in Tilapia", gram positive cocci pathogens of fish in Israel and in the United States were characterized. We showed that Streptococcus shiloi, the name for an agent causing septicemic infection in fish, is a junior synonym of Streptococcus iniae and that Enterococcus seriolicida is a junior synonym of Lactococcus garvieae, a causative agent of septicemia and meningo-encephalitis in fish. Molecular epidemiology studies on these two pathogens, based on 16S rDNA sequences and ribotyping showed that although each country had specific clones, S. iniae originated probably from the U.S. and L. garvieae from Japan. PCR assays were developed for both pathogens and applied to clinical samples. S. agalactiael S. difficile was also recognized for the first time in the U.S. in tilapia. Our histopathological studies explained the noted paradox (abundant in vitro growth often accompanied by scant to small numbers of organisms within the meninges in histologic sections of brain) in diagnostic of fish streptococcus. The greatest concentration of cocci were consistently observed within macrophages infiltrating the extrameningeal fibroadipose tissue surrounding the brain within the calvarium. These results also suggests that the primary route of meningeal infection may be extension from the extrameningeal connective tissue rather than meningeal vascular emigration of cocci-containing macrophages. Our work has resulted in a cognizance of streptococcus as fish pathogen which goes beyond the pathology observed in tilapia and is already extended to many aquaculture fish species in Israel and in the United States. Finally, our data suggest that vaccines (bivalent or trivalent) could be developed to prevent most of the damages caused by streptococcus in aquaculture.

Abstract:
Systematic information on all aspects of agriculture is a significant tool in finding solutions to various problems. This project was initiated to develop a searchable database on taxonomy, host plants, geographic distribution, economic importance and control of scale insects (Hemiptera: Coccoidea). A systematic database has been developed for 17 families of scale insects, namely, Aclerdidae, Asterolecaniidae, Beesoniidae, Carayonemidae, Cerococcidae, Coccidae, Conchaspididae, Dactylopiidae, Eriococcidae, Halimococcidae, Kerriidae, Lecanodiaspididae, Micrococcidae, Ortheziidae, Phenacoleachiidae, Phoenicococcidae and Pseudococcidae. These databases are now available on the Internet in ScaleNet - A Searchable Information System on Scale Insects - a Systematic Database of the Scale Insects of the World, (URL: http://www.sel.barc.usda.gov/scalenet/scalenet.htm ). Since 1997, the year in which ScaleNet was first placed on the Internet, this site became the best worldwide source of information on scale insects. The most reliable evaluation is that the site was 'visited' during 1999 by more than 50,000 users. Messages from the clientele of the site clearly indicate that it is widely used by researchers, applied entomologists, quarantine officers, students as well as the general public.
