Water availability and land‐use shape the diversity of Odonata in the Middle East

open access: yesInsect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

open access: yesInsect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

The influensing of the tick-borne encephalitis virus to the process of metamorphosis of engorged larvaes and nimphs of the tick Ixodes ricinus

open access: yesБюллетень сибирской медицины, 2006
In laboratory experience the conditions for development engorged larvaes (n = 2 500) and nymphs (n = 800) of Ixodes ricinus with diapause (6 h of light) are simulated.

A protracted phenology: Post‐diapause larval development of a threatened butterfly

open access: yesInsect Conservation and Diversity, EarlyView.
Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.

Therapeutic Bark Gouging as an Effective Complement for the Management of Ips typographus and Pityogenes chalcographus While Preserving Habitat for Secondary Scolytine (Coleoptera: Curculionidae) Species

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Norway spruce will likely remain an important tree species in Europe over the next few decades despite efforts to transform forests and reduce its distribution range more to its natural range. Consequently, Ips typographus will remain one of the most relevant forest pests the management of which will become increasingly challenging due to ...

Daily Rhythms of Sex Pheromone Emission and Courtship Behaviour in the Neotropical Brown Stink Bug Euschistus heros

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Understanding the chemical and behavioural ecology of the Neotropical brown stink bug, Euschistus heros (Hemiptera: Pentatomidae), is essential for developing effective integrated pest management (IPM) strategies in South American soybean production. This study investigated the courtship behaviour and diel periodicity of sex pheromone emission.

Embryonic diapause: a unique stage of development

open access: yesClinical Theriogenology
Embryonic diapause is a unique stage of development that occurs in some mammalian species. Diapause serves as an evolutionary reproductive strategy to maximize the survivability of dam and offspring. Although individual mechanisms of control vary among species, the overarching physiology of diapause extends the length of pregnancy to delay parturition ...

THE PHYSIOLOGY OF INSECT DIAPAUSE. VII. THE RESPIRATORY METABOLISM OF THE CECROPIA SILKWORM DURING DIAPAUSE AND DEVELOPMENT

open access: yesThe Biological Bulletin, 1953
The endocrine control of the pupal diapause of the Cecropia silkworm has been the principal theme of the preceding papers of this series. A considerable body of evidence is now at hand pointing to the prothoracic glands as the source of a hormone which reacts with the tissues to terminate the pupal diapause.

Three Decades of China's Bt Cotton: Achievements and Insights

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Cotton is a vital natural fibre crop with significant economic value worldwide. In response to the threat of cotton bollworm (Helicoverpa armigera), the China government initiated a research project in 1992 to develop transgenic Bacillus thuringiensis (Bt) cotton.
