Gene family evolution in insects
Insects are amongst the most successful animal groups of our planet, dominating terrestrial and freshwater ecosystems. The invention of wings is one of the most important key innovations in insects since wings allowed the conquest ...

Evolution of detoxification gene families in insects
Plants and insects are coevolving for over 400 million years (Jensen et al., 2011; Kant et al., 2015). This evolutionary interaction is generally believed to be responsible for the wide scope of plant defense mechanisms and the ad ...

Embryogenesis of Odonata
Odonates (dragonflies and damselflies) have become prominent model systems to study the influence of temperature and photoperiod on insect development and ecology in general. The majority of the studies are covering juvenile state ...

Expression analysis of wing-regulatory genes in Odonata
The wing is a key innovation that evolved once in the evolutionary history of insects, leading to a major radiation and species richness we observe today. Nevertheless, the origin of insect wings remains elusive due to the absence ...

How did generalist insects evolve and what makes them so special?
Begindate and enddate are flexible. Interested in insects? Plant-insect interactions in specific? And would you like to study butterfly diversity by working with genome and transcriptome data? The majority of herbivorous insec ...

Mapping the genes controlling flowering time and vitamin content in the orphan vegetable Gynandropsis gynandra (Cleomaceae)
Spider plant (Gynandropsis gynandra) is a minor leafy vegetable which belongs to the Cleomaceae family, the sister family of Brassicaceae. Besides its food use, the species is used as a medicinal plant in various parts of the worl ...

The evolution of pest cutworm moths (Noctuidae)
Invertebrate pests form a serious economic and ecological threat to worldwide crop yields, especially in times where pressure on agricultural systems is intensifying due to both an increase of the human population and the predicte ...

Evolution of egg-killing in Brassicales
Members of the Brassicaceae family are known to express a hypersensitive response(HR)-like necrosis when cabbage white butterflies (Pieris sp.) lay eggs on their leaves. The plant responds with a local cell death in the leaf under ...

A hitch-hikers guide to egg parasitism
Minute hymenopteran wasps of the genus Trichogramma parasitise eggs of butterflies and moth. They are the most widely used biological control agents worldwide. However, their phylogeny, dispersal behavior, and parasitism capacitie ...

Natural selection of (anti-) sex pheromones by egg parasitoids
Butterfly males can produce and transfer an anti-sex pheromone, a so-called anti-aphrodisiac (AA), to females during mating to render them less attractive to other males. AAs from cabbage white butterflies, Pieris brassicae and ...
