Background: Ungulates from zoological institutions are frequently used as founders in reintroduction programmes. These animals are subject to specific parasite management as parasitic infections have previously been associated with failed Bovidae reintroductions.
Methods: Questionnaires to obtain data on how these institutions screen for seasonal parasite presence and the clinical signs they induced in threatened ungulates were sent to 65 institutions involved in European Ex situ Programmes (58.5% response rate). Temperature and relative humidity data were also obtained to categorize each zoological centre.
Results: Strongyloides spp. (52.6%), Trichuris spp. (42.1%), Trichostrongylidae family (39.4%) and Eimeria spp. (36.8%) were the most frequently reported parasites in the received questionnaires. Climatic variables did not influence parasite presence.
Conclusion: Our results suggest that artificial microenvironments created by husbandry practices and enclosure design in zoos could create hotspots for gastrointestinal parasites. To maximise the success of reintroduction projects, we recommend that the influence of microclimates on parasite burdens be evaluated.

Insect diapause and response to thermal stress are similar in the variety of manifestations. However, the influence of thermal shocks on the incidence of insect diapause has not been sufficiently studied. Our laboratory experiments showed that both cold (-10 °C) and heat (43 °C) shocks experienced for at least 20-30 min significantly reduced the incidence of facultative larval winter diapause in the insect egg parasitoid .

Adult polyphenism is a prevalent form of adaptive evolution that enables insects to generate discrete phenotypes based on environmental factors. However, the morphology and molecular mechanisms underlying adult dimorphism in (a global storage pest) remain elusive. Understanding these mechanisms is crucial for predicting the dispersal and population dynamics of .

Background: The Tephritidae family, commonly referred to as true fruit flies, comprises of a substantial group within order Diptera. Numerous species within this family are major agricultural pests, with a tendency to infest a wide array of fruits and vegetables in tropical and sub- tropical regions, leading to considerable damage and consequent reductions in the market value of the crops.
Methods And Results: The current study was aimed to propose a promising solution to the menace posed by fruit flies by offering rapid, accurate and reliable species identification by using character-based DNA barcode methodology.

Obligatory parthenogenesis in vertebrates is restricted to squamate reptiles and evolved through hybridisation. Parthenogens can hybridise with sexual species, resulting in individuals with increased ploidy levels. We describe two successive hybridisations of the parthenogenetic butterfly lizards (genus Leiolepis) in Vietnam with a parental sexual species.

The genus Gigantorhynchus comprises six valid species that require a terrestrial arthropod as an intermediate host. Cystacanths of G. echinosdiscus were previously reported infecting termites in Brazil.
