Abstract:

The egg parasitoid complex of the pine processionary moth (Thaumetopoea pityocampa) was surveyed for the first time on the Thasos Island, Greece. A total of 96 egg batches containing 20391 eggs were collected between 06 and 10 of September, 2017 from Aleppo pines (Pinus halepensis) at four sites (Skidia, Thimonia, Alyki and Panagia). Four primary parasitoids were identified (Ooencyrtus pityocampae, Baryscapus servadeii, Anastatus bifasciatus and Trichogramma sp.), as well as the hyperparasitoid B. transversalis. Among the parasitoids groups, O. pityocampae was the most common, followed by B. servadeii, whilst the number of other species was low. The highest survival rate was reported for three species: O. pityocampae, B. servadeii and A. bifasciatus, while the highest was the mortality in Trichogramma sp. All emerged adults of O. pityocampae and B. servadeii were female specimens and in A. bifasciatus – males. The number of females of B. transversalis was three times higher than the one of males. Ooencyrtus pityocampae and B. servadeii were the most important parasitoids of T. pityocampa, destroying respectively 27.1% and 9.9% of the host eggs.

Abstract:

Background: Moths of the genus Thaumetopoea are widespread pests in the coniferous and deciduous forests in Bulgaria. Contact with the caterpillars, larval form of different Thaumetopoea species, causes a series of complaints in humans: mainly contact dermatitis (erucism), but also IgE-mediated allergic reactions. The aim of the present pilot study is to investigate the skin reaction after prick tests with allergens from different Thaumetopoea species in a group of people who have frequent contacts with the processionary caterpillars. Material and methods: A group of 42 subjects were surveyed - 37 men and 5 women between the ages of 18 and 87. Specific sensitization to caterpillars of three Thaumetopoea species: Thaumetopoea pityocampa (pine processionary); Thaumetopoea processionea (oak processionary) and Thaumetopoea solitaria (pistachio processionary) was assessed by allergy skin prick tests (SPT) with specially designed caterpillar allergens. Results: Positive allergy skin tests to one or more caterpillar’s allergens were measured in 18 (43%) participants. A simultaneous test with the three allergens from the different Thaumetopoea species showed that in 5 (31%) of the cases, skin hypersensitivity only to allergen from T. pityocampa was present. Monosensitization to T. processionea observed in 2 (12%). The rest 9 (57%) participants with positive skin test show different profiles of polysensitization to Thaumetopoea allergens under study. Conclusions: The evaluation of skin reactivity after SPT with different caterpillar’s allergens outlined the important role of processionary allergens, especially this from T. pityocampa, in the development of IgE-mediated allergic complaints in different groups of forestry professionals. In view of these results, it seems that IgE-mediated hypersensitivity allergic reactions to Thaumetopoea caterpillars are at least as important as those with no allergic mechanism.

Abstract:

A bacterium (strain Tp2T) was isolated from a caterpillar of the pine processionary moth, Thaumetopoea pityocampa (Den. & Schiff.) (Lepidoptera: Thaumetopoeidae), a destructive pine forest pest. The bacterium is a Gram-stain-positive, red-pigmented coccus, oxidase-negative, nitrate-reducing, non-motile and non-spore-forming. Strain Tp2T was subjected to a taxonomic study using polyphasic approach that included morphological and biochemical characterizations, 16S rRNA gene sequence analysis, DNA–DNA hybridization, DNA G+C content analysis, comparative fatty acid profiles, and analyses of quinones and polar lipids. The 16S rRNA gene sequence of strain Tp2T revealed that Arthrobacter agilis DSM 20550T was the closest known strain (98 % 16S rRNA gene sequence similarity). DNA–DNA hybridization of A. agilis DSM 20550T and strain Tp2T resulted in a DNA–DNA relatedness value of 11.9 % (20.2 % reciprocal). The DNA base composition of strain Tp2T was 69.5 mol%, which is consistent with the other recognized members of Actinobacteria that have a high G+C content in their genome. The polar lipid pattern of strain Tp2T consisted of diphosphatidylglycerol (major), phosphatidylglycerol and phosphatidylinositol and unknown glycolipids. The cellular fatty acids were anteiso C15 : 0 and anteiso C17 : 0 and the major menaquinone was MK-9(II-H2). The peptidoglycan type was A3α with an l-Lys–l-Thr–l-Ala3 interpeptide bridge. The above-mentioned characterization qualifies strain Tp2T as genotypically and phenotypically distinct from closely related species of the genus Arthrobacter with validly published names. Strain Tp2T is therefore proposed to represent a novel species of the genus Arthrobacter , described as Arthrobacter pityocampae sp. nov. The type strain is Tp2T ( = DSM 21719T = NCCB 100254T).

Abstract:

The cedar processionary moth, Thaumetopoea bonjeani (Lepidoptera: Notodontidae), is a serious pest of the Atlas cedar Cedrus atlantica in north-western Africa and it is involved in the decline of this endangered tree species. Natural enemies of the cedar processionary moth are poorly known, especially for parasitoids, predators and pathogens of the larval-pupal life stages. Mature larvae were collected and examined in 2014 and 2015 in natural stands of Atlas cedar in the Djurdjura (northern Algeria), in occurrence with pine processionary moth Thaumetopoea pityocampa. The overall mortality rate of larvae of Thaumetopoea bonjeani ranged from 26.4% to 31.1%, with generalist predators and parasitoids being more effective than pathogens. Four primary parasitoid species were recorded, of which four tachinid flies and one braconid wasp, as well as four predatory beetles and one fungus. The most important species were the carabid Calosoma sycophanta and the tachinid Compsilura concinnata. The cooccurrence of T. bonjeani and T. pityocampa may offer to generalist natural enemies an extended period of availa- bility of similar preys, as the two processionary moths have different life cycles. The sharing of natural enemies between the two species of Thaumetopoea can mitigate the outbreaks of both species.

Abstract:

This work deals with the taxonomic study of a bacterium, strain Tp12T, isolated from caterpillars of the pine processionary moth (Thaumetopoea pityocampa Denis & Schiffermüller, 1775; Lepidoptera, Thaumetopoeidae). The isolate was assigned to the genus Brevibacterium on the basis of a polyphasic taxonomic study, including morphological and biochemical characteristics, 16S rRNA gene sequence analysis, fatty acid analysis and DNA G+C content. The highest 16S rRNA gene sequence similarity to this isolate was approximately 96 %, with the type strains of Brevibacterium album and Brevibacterium samyangense. Cellular fatty acids of the isolate are of the branched type, with the major components being anteiso-C15 : 0 and anteiso-C17 : 0. The DNA G+C content was 69.8 mol%. Although the strain was related to B. album and B. samyangense according to 16S rRNA gene sequence analysis, it differed from any known species of Brevibacterium. Based on this evidence, the novel species Brevibacterium pityocampae sp. nov. is proposed, with strain Tp12T (=DSM 21720T =NCCB 100255T) as the type strain.

Abstract:

Caterpillars of the pine processionary moths, Thaumetopoea complex, cause serious defoliation to Cedrus, Pinus, and Pseudotsuga trees. Thaumetopoea caterpillars also have fine hairs on their abdominal tergites that contain a protein that can severely irritate and cause dermatitis in humans and domestic animals. The control of the T. pityocampa pine processionary moth has become necessary in many European countries because of the sanitary risks that are related to larval urtication and the defoliation threat to pine forests and plantations. New research activities have been aimed at the development of eco-friendly, innovative technologies for Integrated Pest Management (IPM) of these moths, particularly in urban parks and woodland recreational areas. This paper describes the recent advances in the use of pheromones in monitoring, mass trapping, and mating disruption related to management of processionary moths T. hellenica and T. pityocampa. According to the results, the use of pheromones may provide a practical alternative to insecticide sprays, as they can be safe and simple as compared to other control methods.

Abstract:

SummaryMating disruption (MD) has been a successful approach for pest control of several lepidoptera. Field trials to evaluate the efficacy of communication disruption of low pheromone load formulation on Thaumetopoea pityocampa were carried out in 2010 and 2011 in an urban park. The efficacy of MD was assessed by comparing male T. pityocampa catches in pheromone traps, between MD and Control areas. In the 1st year of the application the percentage of male inhibition ranged from 85 to 100% during the 1st month of the flight period and 95-100% during the whole flight period in the 2nd year. The pheromone remained in the polymeric matrix was almost 30% after 7 weeks under laboratory aging conditions. Combining the pheromone release results with the male disorientation results we can assume that after 7 weeks the remaining pheromone concentration was still sufficient to achieve MD. This study indicates that air permeation with the major sex pheromone component (Z)-13-hexadecen-11-ynyl acetate, at a rate of 20 g/ha for one application per season, can affect the orientation of T. pityocampa males. Since mating disruption is an environmentally safe method for pest control, it could be a valuable tool to control T. pityocampa in urban areas and parks.

Abstract:

The tachinid parasitoids (Diptera: Tachinidae) of the pine processionary moth (Thaumetopoea pityocampa) were studied in 2019 and 2020 in the Eastern Rhodopes (Fotinovo, Kandilka and Sarnak vills.), the Western Rhodopes (Dobrostan vill.) and the Struma Valley (town of Sandanski). In total, 1193 larvae and pupae of T. pityocampa were collected in 40-50-year-old Pinus nigra plantations. They were transported and observed in laboratory conditions at 20-22 °С. Three parasitoids, Compsilura concinnata, Exorista (Exorista) fasciata and Phryxe vulgaris were reared from the host. In this study, E. fasciata was established for the first time in trophic association with T. pityocampa. In addition, P. vulgaris was confirmed as a parasitoid of the host. The mortality of the pine processionary moth caused by tachinids in different localities was 0.5-5.3%, with an average of 2.6% for the country.

Abstract:

To investigate the factors affecting the emergence of the pine processionary moth (Thaumetopoea pityocampa) in laboratory conditions, a number of 1487 larvae, prepupae and pupae were collected in the period February-May 2019 from five pest habitats: Fotinovo and Kandilka villages (inhabited by a summer phenological form), Sandanski and Klisura towns (winter phonological form occurs) and Sarnak village (both forms occur). At the date of collection, the rate of parasitism was very low (0-0.1%). Throughout the study, significant differences in the characteristics of pupal stage and mortality between both phenological forms were established. The rate of emerged adults varied from 21.4% to 77.6% in the observed habitats. The sex ratio between female and male specimens was almost equal. Only 0.6% of samples emerged in the second year, after diapause. In four localities (Fotinovo, Kandilka, Sandanski and Sarnak), the rate of infection by entomopathogens was between 6.0% and 20.8%, and the parasitism caused by tachinids – between 0.9% and 3.4%. The flight period of the summer and winter phenological forms of T. pityocampa were clearly differentiated with about a month. In summer form, the flight began in late May and ended in the last decade of June, and in winter form – from early July to the end of August. The duration of the flight period in both forms lasted 30 to 50 days with an equal number of emerged male and female specimens.

Abstract:

The pine processionary moth (Thaumetopoea pityocampa) was reported for the first time in North Bul-garia in 2022. Winter nests of the pest were observed in a number of pine plantations in more than 10 sites of four Forest State Enterprises (Troyan, Sevlievo, Gabrovo, Plachkovtsi). The penetration of the pest into the new localities is due to a long-distance dispersion by vehicles. In January 2023, the nests in new localities contained fifth-instar larvae of T. pityocampa. Only about 3% of them were empty as larvae had descended in the soil for pupation. Based on the high population density and presence of old nests in some localities, it was assumed that the pest penetrated into Northern Bulgaria most likely 3-4 years ago.

Abstract:

Studies on egg parasitoids of the pine processionary moth (Thaumetopoea pityocampa) were conducted during the period 1991-2018 in native localities of the pest on the Balkan Peninsula and in Asia Minor. In Bulgaria the biological material (2510 egg batches and 579273 eggs) was collected in 48 host localities. A number of 650 egg batches and 135611 eggs were studied from the Balkan countries (North Macedonia, Bosnia and Herzegovina, Albania and Greece), and in the Asian part of Turkey (Asia Minor), the biological material was examined from nine habitats. Eight species of egg parasitoids (Ooencyrtus pityocampae, Baryscapus servadeii, B. transversalis, Pediobius bruchicida, Anastatus bifasciatus, Eupelmus vesicularis, E. vladimiri and Trichogramma sp.) were found. The total regulating effect of egg parasitoids in Bulgaria was on average 17.6%, and in the other Balkan countries – 24.9%. Trichogramma sp. was found in 63.1% of the analysed samples in Bulgaria and in 55.6% from the neighboring countries. The percent of parasitism of T. pityocampa eggs by Trichogramma sp. was low - on average 0.39% for Bulgaria and 0.73% for the other Balkan countries. The relative share of the species in the total percentage of parasitised eggs for Bulgaria and the other countries was 2.2% and 2.9%, respectively.

Abstract:

A lagarta do pinheiro, Thaumetopoea pityocampa, é um inseto desfolhador responsável pelo atraso do crescimento ou a morte de vários tipos de pinheiros. Além de danos ambientais a lagarta pode provocar reações cutâneas em humanos pelo contato com os pelos irritantes das larvas. Embora a dermatite ocorra entre grupos de profissionais de ar livre, afecta principalmente grupos não-ocupacionais. Os meios de transmissão compreendem o contato directo com o ninho e/ou processionária e o contato indireto com os pelos dispersos no ar. A dermatite é geralmente observada no final da Primavera, particularmente, de Março a Junho, entre os ultilizadores de parques de campismo. A erupção cutânea tem início 1-12 horas após o contato com os pêlos e apresenta-se com prurido intenso e persistente. Para além da pele, a T. pityocampa pode envolver a olhos e a via aérea, mas de forma menos frequente. Apesar dos danos consideráveis para os seres humanos e para natureza, a infestação é um problema subestimado; a literatura médica é escassa e, muitas vezes, a informação relevante é a que se refere aos meios de comunicação locais e à sabedoria popular.

Abstract:

The sustainable protection of cedar stands in Chréa National Park can only be accomplished through the stability of the ecosystem. Outbreaks of Thaumetopoea pityocampa are a major threat and are largely attributed to the high population fecundity, changes in the diversity of natural enemies and global interactions within the ecosystem. Egg parasitoids (Hymenoptera) are essential in the biological control of T. pityocampa. To assess the impact of the parasitoids on the populations of the pine processionary moth, egg masses from cedar plantations were collected, reared in a laboratory and checked regularly for the emergence of the egg parasitoids: Trichogramma embryophagum, Baryscapus servadeii and Ooencyrtus pityocampa. Observations showed an inter-annual variation in the abundance of the three parasitoids as a result of the variation in the population density of the processionary moth, and on the underlying effect of temperature. Parasitoids had variable parasitism rates, with yearly averages ranging from 3.86% to 51.14%, dependent on the spatiotemporal distribution of the host populations. The aggregate effect of multiple parasitoid species could optimize control of T. pityocampa in cedar stands.

Abstract:

Abstract The pine processionary moth, Thaumetopoea pityocampa (Denis and Schiffermüller), is an important insect in the Mediterranean region, as it defoliates pines and its urticating hairs can cause allergic reactions in humans and animals. Moreover, this species exhibits an interesting genetic structure as recently a distinct East-North African mtDNA lineage (‘ENA clade’) has been described. This clade has been recently detected in Greek populations where it has currently expanded its range by replacing the ‘endemic’ T. pityocampa lineages. Here, we report new data on the rapid spread of ‘ENA clade’ in the Greek island Evoia in only a few years. As the underlying mechanisms of the ‘ENA clade’ range expansion has not been studied so far, we screened T. pityocampa for an infection with the heritable bacterial endosymbionts Wolbachia (Bacteria: Anaplasmataceae), Cardinium (Bacteria: Bacteroidaceae), Rickettsia (Bacteria: Rickettsiaceae) and Spiroplasma (Bacteria: Spiroplasmataceae). These bacteria can manipulate the reproduction of infected hosts, something that could potentially explain the rapid spread of ‘ENA clade’ lineage. Therefore, we screened 28 individuals that exhibited T. pityocampa ‘ENA clade’ and ‘endemic’ T. pityocampa haplotypes from nine populations scattered all over Greece. None of them was infected with any of the four endosymbionts, suggesting that these bacteria do not cause reproductive manipulations in T. pityocampa lineages and, thus, other factors should be explored in future research efforts.

Abstract:

Abstract Thaumetopoea pityocampa (Denis and Schiffermüller) is a severe defoliator of various species of Pinus and Cedrus, while the urticanting hairs produced by its larvae cause public health problems for humans and pets. In the present study, we report results of trials (from summer 2015 until winter 2017) of mating disruption for management of T. pityocampa in different areas of Italy and Greece. Overall, the total number of male moths captured in mating disruption-treated plots over each season (70) was significantly lower than the respective number in untreated plots (780). The total number of winter nests was likewise significantly less in the mating disruption plots (13) compared with control plots (147). Our results indicate that mating disruption can be an important tool for judicious, insecticide-free control of T. pityocampa in urban, suburban, and recreational areas, where many alternative control measures are not available.

Abstract:

Outbreaks of the processionary moth Thaumetopoea pityocampa (Denis & Schiffermüller, 1775), a forest pest from the Palearctic, are thought to induce a behavioral response of bats, but up to now the moth has been seldom identified as bats’ prey. Studies on bat diets suggest moths with cyclical outbreaks attract a wide array of bat species from different foraging guilds. We test whether bats feed upon T. pityocampa in the Iberian Peninsula irrespective of the predator’s ecological and morphological features. We found that seven out of ten bat species belonging to different foraging guilds contained T. pityocampa DNA in their faeces and no difference was found in the foraging frequency among foraging guilds. A different size of the typical prey or the lack of fondness for moths can explain the absence of the pest in some bat species. Moreover, the intraspecific foraging frequency of T. pityocampa also changed with the sampling site likely representing differential availability of the moth. Lack of information on flight and dispersal behavior or the tympanate nature of the adult moth complicates understanding how different foraging guilds of bats prey upon the same prey. Our data suggests that T. pityocampa is a remarkable food source for many thousands of individual bats in the study area and we anticipate that more bats besides the species studied here are consuming this moth.

Abstract:

ABSTRACT The insecticidal activity and receptor binding properties ofBacillus thuringiensis Cry1A toxins towards the forest pests Thaumetopoea pityocampa (processionary moth) andLymantria monacha (nun moth) were investigated. Cry1Aa, Cry1Ab, and Cry1Ac were highly toxic (corresponding 50% lethal concentration values: 956, 895, and 379 pg/μl, respectively) to first-instar T. pityocampa larvae. During larval development, Cry1Ab and Cry1Ac toxicity decreased with increasing age, although the loss of activity was more pronounced for Cry1Ab. Binding assays with 125I-labelled Cry1Ab and brush border membrane vesicles from T. pityocampa first- and last-instar larvae detected a remarkable decrease in the overall Cry1Ab binding affinity in last-instar larvae, although saturable Cry1Ab binding to both instars was observed. Homologous competition experiments demonstrated the loss of one of the two Cry1Ab high-affinity binding sites detected in first-instar larvae. Growth inhibition assays with sublethal doses of Cry1Aa, Cry1Ab, and Cry1Ac in L. monacha showed that all three toxins were able to delay molting from second instar to third instar. Specific saturable binding of Cry1Ab was detected only in first- and second-instar larvae. Cry1Ab binding was not detected in last-instar larvae, although specific binding of Cry1Aa and Cry1Ac was observed. These results demonstrate a loss of Cry1Ab binding sites during development on the midgut epithelium of T. pityocampa and L. monacha, correlating in T. pityocampa with a decrease in Cry1Ab toxicity with increasing age.

Abstract:

Pine processionary moths, Thaumetopoea wilkinsoni Tams, 1924 and Thaumetopoea pityocampa ([Denis & Schiffermüller], 1775) (Lepidoptera: Notodontidae) are among the most destructive pine pests in Mediterranean basin. Their larvae descend to the ground from the canopy in spring for pupation and rest there until late summer. Although this is the general pattern, pupal period is a plastic feature and can be prolonged for up to several years. It is considered one of several difficulties of processionary moth management as such a plasticity provides a continuous support from the underground reservoir to the pest population. This phenomenon has been known for a long time and its discovery has been attributed to Guy Démolin; renowned INRA (France) researcher. Here, we report an unnoticed researcher, Ömer Besçeli, from Turkey who published the phenomenon of prolonged diapause in the pine processionary moth earlier.

Abstract:

The pine processionary moth Thaumetopoea pityocampa (Denis & Schiffermuller, 1775) (Lepidoptera: Notodontidae) is one of the main pests in pine forests and an indicator species for global warming. Its expansion in Europe is considered one of the signals for changing climate. While other countries in the species range have a Mediterranean or oceanic climate, Bulgaria has a predominantly continental climate, which allows to see the pine processionary in a different light. For example, in Bulgaria, climate change is not causing expansion, but rather a habitat shift.

Abstract:

In the Atlas cedar forests located on the northern massifs of the Blidean Atlas and at the eastern extension of the Saharan Atlas, 79 egg batches of processionary moth Thaumetopoea pityocampa (Denis & Schiffermuller, 1775) were collected during the summer period from two sites: Chrea National park (46), and Ouled Yagoub forest (33). To assess the effect of the egg batches characteristics on the parasitism, the eggs were monitored after the hatching of the larvae and/or the emergence of the parasitoids. The average number of eggs/batches in the Ouled Yagoub site (184 eggs) was significantly higher than of the population of Chrea (151). Data analysis showed that the means comparisons of the hatched and unhatched number of eggs between the two sites were significant. In the case of the population of Chrea, the egg mass was laid in the form of a cylinder on twigs of relatively small diameters while for the population of Ouled Yagoub eggs were laid in the form of plates on twigs of larger diameter, thus more exposed to parasitoids. For the two populations, three active egg parasitoids were identified: Ooencyrtus pityocampae (Mercet, 1921) (Encyrtidae), Baryscapus servadeii (Domenichini,1965) (Eulophidae), and Trichogramma embryophagum (Hartig, 1838) (Trichogrammatidae), the most dominant. These parasitoids were heterogeneously distributed on the egg batches collected in the cedar’s plantation of the Chrea, but homogeneously on the egg batches collected in the Ouled Yagoub cedar forest. The activity and distribution of parasitoids on the egg-laying surface are influenced by the form on the branch chosen by the female.

Abstract:

Objectives The aim of this study was to describe the clinical manifestations in cats of contact with caterpillars of the pine processionary moth. Methods Data were retrospectively obtained from the medical records (2004–2016) of cats that had been in contact with caterpillars of the pine processionary moth. Results Eleven cats were included in the study. The prevalence of lepidopterism was 0.13%. Tongue lesions and ptyalism were both present in 10/11 (91%) cats. Systemic signs consisted exclusively of vomiting and were encountered in 4/11 (36%) cats. The survival rate was 100%. Long-term follow-up data were available for 7/11 cats, and none of the cats showed impaired quality of life or definitive sequelae. Conclusions and relevance The clinical presentation of lepidopterism in cats appears to be similar to that in other animals; however, the clinical signs are less severe than those previously reported, mainly owing to the cautious behaviour of this species. Moreover, the prognosis is excellent, the length of hospitalisation is short (maximum 48 h) and our study showed the absence of any long-term disability after hospital discharge.
