Behavioural plasticity can drive the evolution of new traits in animals. In oviparous species, oviposition behaviour could promote egg by exposing them to different selective pressures novel sites. Individual females predatory stink bug Podisus maculiventris are able selectively colour their eggs depending on leaf side, laying lightly pigmented undersides and more eggs, which resistant ultraviolet (UV) radiation damage, tops. Here, we propose an evolutionary scenario for P. pigmentation its...
Abstract Conflicts in animals are usually resolved based on asymmetries, where contest winners often those that value a resource the most and/or who have greatest potential to retain it. In parasitoid wasps, contests between females determine which individual exploits hosts for offspring production. Previous studies solitary parasitoids rarely considered role of biotic factors generating phenotypic variation could influence strength asymmetries. Some species parasitize host various sizes,...
AbstractMany animals lay their eggs in clusters. Eggs on the periphery of clusters can be at higher risk mortality. We asked whether most commonly occurring clutch sizes pentatomid bugs could result from geometrical arrangements that maximize proportion cluster's interior. Although common do not correspond with geometric optimality, stink tend to shapes protect increasing proportions offspring as increase. also considered ovariole number, an aspect reproductive anatomy may a fixed trait...

Abstract Antipredation strategies are important for the survival and fitness of animals, especially in more vulnerable life stages. In insects, eggs early juvenile stages often either immobile or unable to rapidly flee hide when facing predators. Understanding what alternative antipredation they use, but also how those change over development time, is required fully appreciate species have adapted biotic threats. Murgantia histrionica a stink bug, conspicuously colored from egg adult, known...
Le chamaemyide annelé, Leucopis annulipes, est un prédateur furtif aphidiphage indigène au Québec qui vit contact des colonies de pucerons lui servent proies.Bien que cette espèce soit encore largement méconnue, résultats préliminaires indiquent potentiel en tant qu'agent lutte biologique contre les pucerons.L'objectif du présent travail était déterminer taux mortalité trois stades immatures (oeuf, larve et nymphe) ainsi la longévité adultes L. annulipes laboratoire, puis comparer avec ceux...
