Abstract:

Attractive and repellent properties of many household chemicals may be used to combat synantrophic insects, such as cockroaches. In the natural environment, Shelfordella lateralis (Walker, 1868) (Blattodea, Blattidae) lives in the area spanning Central Asia to North Africa. Furthermore, in many tropical and subtropical countries, it is common in human accomodations. In the laboratory conditions, we determined reaction of cockroaches to aromatic mixtures and medicinal plants often used in households. Attractiveness coefficient was the lowest for cosmetic mixtrures Tutti-fruti and Verbena and Bamboo; other cosmetic aromatizers did not repell this insect (Lilac, Mango) or repelled it poorly (Grapefruit, Amaretto, Pine). Food additives that significantly repelled Sh. lateralis are Apricot, Barberry and Kiwi and lower effects were produced by Biscuit, whereas Vanilla flavouring had no repellent effect. Mixtures for vaping Strawberry pie, Pear, Frozen forest, Irish Cream and Blue Magic exerted strong repellent effects on cockroaches. Low repellent effect on Sh. lateralis were exerted by vaping mixtures Pancakes with Honey, Turkish Tobacco and Grapefruit. No significant effects on the number of cockroaches were exerted by vaping mixtures Vanilla, Club Ice Cream, Blueberry Smoke, Mojito, Chocolate, Apple, Mint and Walnut. Out of the fishing lures, the strongest repellent effects on Sh. lateralis were taken by Blood Worm, Onion and Honey, and weaker effects were exerted by Corn and Vanilla. Imagoes of Sh. lateralis were most significantly repelled by essential oils from jojoba, eucalyptus, daisy, tee tree, Cao Sao Vang balsam, and also fir essential oil. Neither luring nor repellent effects on imagoes of Sh. lateralis were displayed by essential oils from lemon, aloe, peppermint and mandarin. Dry medicinal plants repelled imagoes of Sh. lateralis: inflorescences of Calendula officinalis, leaves of Artemisia absinthium, flowers of Jasminum officinale, leaves of Origanum vulgare, inflorescences of Matricaria chamomilla, inflorescences of Crataegus monogyna, leaves of Mentha x piperita, inflorescences of Achillea millefolium, leaves of Hypericum perforatum, leaves of Aristolochia clematitis and inflorescences of Tanacetum vulgare. No repellent effects on Sh. lateralis were exerted by Chelidonium majus, inflorescences of Tilia cordata and inflorescences of Helichrysum arenarium. Thus, most (40 of 58, or 69.0%) of the tested aromatic substances and medicinal plants repelled synantrophic Turkestan cockroach, while a much smaller share (31.0%) neither significantly lured nor repelled them. No aromatic mixtures attracted Sh. lateralis in our experiment.

Abstract:

Abstract The goal of the present study was to investigate the olfactory attractiveness of air-dried insects used as aromas to dogs. The trial consisted of 35 adult dogs (20 males, 15 females) aged between 12 months and 7 years (mean = 3.6), varied in terms of breed, kept as companion animals. The dogs had free olfactory access to selected unprocessed dried insects, i.e., mealworm (Tenebrio molitor), Turkestan cockroach (Shelfordella lateralis), black soldier fly (Hermetia illucens), and tropical house cricket (Gryllodes sigillatus), as well as commercial dried and pelleted dog feed, which was used as a control treatment. Samples (100 g) were located separately in non transparent closed boxes with 5 perforations in the cover (7 mm each) to improve the intensity of the aromas without direct contact with the tested samples. The box was recorded as chosen when the dog showed interest in it for more than 15 seconds continuously per each attempt (3 attempts per dog). The presented study shows that the selected insect species were chosen as frequently as the control group (P=0.03). However, in terms of preferences by dog gender, Tenebrio molitor was favored more often by males than by females, which preferred Shelfordella lateralis. The current preliminary data suggest that the olfactory features of the selected insect species may be attractive to dogs.

Abstract:

The Turkestan cockroach <em>Shelfordella lateralis</em> is a peridomestic species originally from the Middle East and Central Asia, which has recently become an invasive species in the USA, Mexico, Japan and Sardinia, where it is considered as a pest. We provide the first records of this species from Cyprus and Turkey, making these the second records of established populations of the Turkestan cockroach in Europe. We also provide biological information regarding its reproduction in semi-natural conditions in Cyprus, as well as a detailed description and images of the male genitalia.

Abstract:

Finding substantial substitution of chemical pesticides to control cockroaches, which were proved to have a link with multiple health issues, has become the major target of many researchers. In fact, subjecting this pest to the effects of toxic plants extracts is considered ideal to primarily avoid jeopardizing human health. This study is divided into two objectives. The first of which is to confirm the toxicity of the ethanoic extract from the Cleome arabica plant on two species of urban cockroaches; which are Bllattella germanica and Bllatta lateralis, while the second is to verify the effect of the attractive odor of the extract on the feeding behavior of the two already mentioned species. Therefore, the findings demonstrated that, on the one hand, the extract causes a mortality rate of 60% of B. germanica after 30 days of treatment at a high concentration of (3g/l). On the other hand, mortality rate in B. lateralis does not exceed 6.7%. Further, findings exhibited that the proportion of B. germanica attracted by the smell of the plant soaked in hexane at a specified time (15, 30 and 60 minutes) was estimated at 40%, whereas that of B. lateralis exceeded 60%. The results of this work suggest the presence of toxic substances in the studied extract which may lead to the development of bio-insecticides based on Cleome arabica to be used in the pesticide market.

Abstract:

The work is devoted to the study of the reproductive performance of a narrow areal triploid toads (Batur toad, Bufotes baturae) reared on different live food (Turkestan and marble cockroaches). Material for the work was obtained over three breeding seasons. In the first breeding season, the number of pairs reared on the Turkestan cockroach (Shelfordella lateralis) was 7 (64%) and on the marbled cockroach (Nauphoeta cinerea) – 2 (18%). In the second and third seasons, the numbers were 8 (89%) and 11 (100%) respectively. The average fecundity of females fed on the Turkestan cockroach ranged from 3149 to 3300 eggs over three seasons, while that of females fed on the marbled cockroach ranged from 2472 to 2630 eggs. However, the juveniles from the group reared on marbled cockroach were superior in length to the prelarvae, as well as in length and weight to the post-metamorphic juveniles. Thus, there was no clear advantage in reproductive performance in animals consuming different diets. Both insect species were highly effective when fed to Baturian toads under laboratory conditions.

Abstract:

ABSTRACTTermites and cockroaches are closely related, with molecular phylogenetic analyses even placing termites within the radiation of cockroaches. The intestinal tract of wood-feeding termites harbors a remarkably diverse microbial community that is essential for the digestion of lignocellulose. However, surprisingly little is known about the gut microbiota of their closest relatives, the omnivorous cockroaches. Here, we present a combined characterization of physiological parameters, metabolic activities, and bacterial microbiota in the gut ofShelfordella lateralis, a representative of the cockroach family Blattidae, the sister group of termites. We compared the bacterial communities within each gut compartment using terminal-restriction fragment length polymorphism (T-RFLP) analysis and made a 16S rRNA gene clone library of the microbiota in the colon—the dilated part of the hindgut with the highest density and diversity of bacteria. The colonic community was dominated by members of theBacteroidetes,Firmicutes(mainlyClostridia), and someDeltaproteobacteria. SpirochaetesandFibrobacteres, which are abundant members of termite gut communities, were conspicuously absent. Nevertheless, detailed phylogenetic analysis revealed that many of the clones from the cockroach colon clustered with sequences previously obtained from the termite gut, which indicated that the composition of the bacterial community reflects at least in part the phylogeny of the host.

Full text

Abstract:

This study analysed the mechanism of avoidance behaviour by adult Turkestan cockroaches (Shelfordella lateralis Walker) in response to a static electric field (S-EF) formed in the space between a negatively charged polyvinyl chloride-insulated iron plate (N-PIP) and a grounded metal net (G-MN). The negative surface charge supplied to the iron plate by a voltage generator caused the G-MN to polarise positively via electrostatic induction. In the S-EF, the negative charge of the N-PIP created a repulsive force that pushed free electrons in the field toward the ground via the G-MN. When insects released in the space surrounded by the S-EF inserted their antennae into the S-EF, they pulled them back reflexively and moved backward. The analysis indicated that an electric current flowed transiently toward the ground when an insect inserted its antennae into the S-EF. The insect became positively charged via this discharge and was attracted to the opposite pole (N-PIP). In response to this attractive force, the insect pulled its antennae back quickly. The positive electrification caused by the removal of free electrons from the antenna tip triggered the avoidance behaviour.

Abstract:

While cockroaches are commonly exhibited in zoos and museums, studied in research laboratories, and even kept as pets, scientifically based guidelines for their euthanasia are lacking. This study assessed euthanasia techniques in four species of cockroaches (Dubia (Blaptica dubia), red runner (Shelfordella lateralis), Madagascar hissing (Gromphadorhina portentosa), and giant cave (Blaberus giganteus)). In an initial pilot study, two hundred fifty adult Dubia cockroaches were exposed in groups of ten to a cotton ball soaked with 2 mL of isoflurane in a 1 L air-tight chamber. Thirty minutes beyond loss of any individual movement, groups were exposed to one of the following secondary treatments: freezing at −18 °C or −80 °C from 0.25 to 24 hours; immersion in 10% neutral buffered formalin, 70% isopropyl alcohol, or reverse osmosis water for 0.25 or 0.5 hours; or intracoelomic injection of potassium chloride (456 mEq/kg) or pentobarbital-based euthanasia solution (3.9 g/kg). A control group remained in the air-tight isoflurane chamber for 24 hours. Following all treatments, cockroaches were monitored for an additional 24 hours for spontaneous movement. Irreversible loss of movement was considered synonymous with irreversible loss of consciousness (death). Across all species, isoflurane anesthesia followed by either 70% isopropyl alcohol immersion for 0.25 or 0.5 hours or isoflurane exposure for 24 hours resulted in euthanasia in 100% of cockroaches. This study is the first evaluation of American Veterinary Medical Association-recommended euthanasia protocols in cockroaches.

Abstract:

The introduction of non-native animals occasionally results in the co-introduction of their microbial symbionts or parasites. The trade of exotic pets and zoo animals has inadvertently introduced several parasitic species to countries where they are non-native. Both the presence of suitable native hosts and opportunity for dispersal determine whether these non-native species become naturalized. During our studies dealing with species of Herpomyces (Ascomycota, Laboulbeniomycetes), fungi that are exclusively ectoparasitic on cockroaches (Hexapoda, Blattodea), we make use of artificial colonies. Most of our specimens originate from pet stores and laboratory populations. Although they were originally intended for transmission studies, we discovered that some cockroaches from artificial colonies carried fruiting bodies of Herpomyces. We screened a total 292 cockroaches from 11 populations that we maintained after purchase. Sources were different pet stores, a toxicological laboratory, and a biological supply company. In eight populations, we found at least some Herpomyces-infected cockroaches. Parasite prevalence varied between 8.77% and 86.33%. Host associations were Blatta orientalis with Herpomyces stylopygae, Blattella germanica with H. ectobiae, Periplaneta americana with H. periplanetae, Phoetalia pallida with H. leurolestis, and Shelfordella lateralis with an undescribed species of Herpomyces. Apart from the new reports, host associations, and consequences for taxonomy (a new species based on morphological and molecular characters), we started to think about the geographic distributions of these fungi and how we, humans, shape them through spreading hosts and through international pet trade. We reviewed the currently known records of Herpomyces-associated cockroaches and host-parasite relationships. Based on the available data, on a global scale, at least half of the currently known species of Herpomyces are spread by globally invasive host species and through international pet trade. This indicates that the distribution and host range of these obscure and often unnoticed fungi are affected by human activities.

The blattid cockroach Periplaneta arabica (Bey-Bienko, 1938) has been poorly understood since its original description. In this study, male and female (including nymph) of P. arabica are paired using DNA barcoding, and their morphological characters (including both external characteristics and genitalia) are described. A detailed comparative morphological study of this species and the closely related Periplaneta americana (Linnaeus, 1758) and Periplaneta lateralis Walker, 1868 was carried out to explore phylogenetically relevant characters.

Abstract:

Cockroach (Blattodea, Blaberoidea) fauna of the Maltese Islands. Hitherto seven species of cockroaches were known from the Maltese Archipelago (Schembri 1980): four of them are synanthropic species introduced by man: Blatta orientalis, Blattella germanica, Periplaneta americana and Supella longipalpa; the remaining three are indigenous species: Ectobius kraussianus, Loboptera decipiens and Polyphaga aegyptiaca. The earlier reports almost exclusively concern the largest island Malta; only one report (L. decipiens) applies to the islet Comino.  Faunistic part. By recent collectings of the authors (mainly A.S.) including also the smaller islands Gozo, Comino and some rock islets (Cominotto, Filfla, Fungus Rock, Large Blue Lagoon Rock, Pigean Rock) the known distribution of the species could be largely widened; two further obviously indigenous species were found, both new to science and presumably endemic to Malta: Ectobius melitensis, sp. nov. (Ectobiidae, Ectobiinae) and Heterogamisca jeffreyana, sp. nov. (Corydiidae, Corydiinae). E. kraussianus presumably has to be eliminated from the list of Maltese cockroaches; the older report most likely concerns a misidentified E. melitensis. During the last years the number of introduced species was strongly increased (1) by escapees of species cultivated for the nourishment of amphibia and reptilia, as are Blaptica dubia, Gromphadorhina sp., Nauphoeta cinerea, Periplaneta fuliginosa, Shelfordella lateralis and Symploce pallens, and (2) by species presumably imported with gardening materials: Pycnoscelus surinamensis and Phoetalia pallida. The mentioned species have repeatedly been found in human buildings and adjacent gardens of a number of settlements, mostly in the surroundings of the capital Valetta. They seem to be well established there; part of them has even been observed in the wild. The newly introduced species are in spite of their successful establishment and reproduction in Malta not considered as a danger for the indigenous species: The great differences in the requirements between the two groups most likely exclude competition between them. Three species, Ectobius vittiventris, Henschoutedenis flexivitta, and Periplaneta australasiae, have only occasionally been found and can, therefore, scarcely be considered as members of the Maltese fauna; the latter also applies to species of the genus Panchlora which were repeatedly observed on fruit markets at freshly imported bananas, but never found outside, neither in the Maltese banana plantations. Taxonomic part. The new species are described and compared with their closest relatives, colouration and characteristic structures are shown in several figures. Ectobius melitensis belongs to the kraussianus-species group of Ectobius known from Sicily and surrounding islands (Ustica, Aeolian Islands, Ponza), but with one species also reaching Albania; the nearest relatives of Heterogamisca jeffreyana are occurring on the Iberian Peninsula and North Africa (Morocco, Algeria, Tunisia).

Abstract:

A multitude of factors affect the assemblies of complex microbial communities associated with animal hosts, with implications for community flexibility, resilience and long-term stability; however, their relative effects have rarely been deduced. Here, we use a tractable lab model to quantify the relative and combined effects of parental transmission (egg case microbiome present/reduced), gut inocula (cockroach vs. termite gut provisioned), and varying diets (matched or unmatched with gut inoculum source) on gut microbiota structure of hatchlings of the omnivorous cockroach Shelfordella lateralis using 16S rRNA gene (rDNA) amplicon sequencing. We show that the presence of a pre-existing bacterial community via vertical transmission of microbes on egg cases reduces subsequent microbial invasion, suggesting priority effects that allow initial colonizers to take a stronghold and which stabilize the microbiome. However, subsequent inoculation sources more strongly affect ultimate community composition, and their ecological networks, with distinct host-taxon-of-origin effects on which bacteria establish. While this is so, communities respond flexibly to specific diets in ways that consequently impact predicted community functions. In conclusion, our findings suggest that inoculations drive communities towards different stable states depending on colonization and extinction events, through ecological host-microbe relations and interactions with other gut bacteria, while diet in parallel shapes the functional capabilities of these microbiomes. These effects may lead to consistent microbial communities that maximize the extended phenotype that the microbiota provides the host, particularly if microbes spend most of their lives in host-associated environments.

In conclusion, our findings suggest that inoculations drive communities toward different stable states depending on colonization and extinction events, through ecological host-microbe relations and interactions with other gut bacteria, while diet in parallel shapes the functional capabilities of these microbiomes. These effects may lead to consistent microbial communities that maximize the extended phenotype that the microbiota provides the host, particularly if microbes spend most of their lives in host-associated environments. IMPORTANCE When host fitness is dependent on gut microbiota, microbial community flexibility and reproducibility enhance host fitness by allowing fine-tuned environmental tracking and sufficient stability for host traits to evolve. Our findings lend support to the importance of vertically transmitted early-life microbiota as stabilizers, through interactions with potential colonizers, which may contribute to ensuring that the microbiota aligns within host fitness-enhancing parameters. Subsequent colonizations are driven by microbial composition of the sources available, and we confirm that host-taxon-of-origin affects stable subsequent communities, while communities at the same time retain sufficient flexibility to shift in response to available diets. Microbiome structure is thus the result of the relative impact and combined effects of inocula and fluctuations driven by environment-specific microbial sources and digestive needs. These affect short-term community structure on an ecological time scale but could ultimately shape host species specificities in microbiomes across evolutionary time, if environmental conditions prevail.
