About Georg Petschenka

Georg Petschenka, With an exceptional h-index of 20 and a recent h-index of 19 (since 2020), a distinguished researcher at Universität Hohenheim, specializes in the field of Chemical Ecology, Insect Physiology, Evolutionary Biology, Insect adaptations to plant toxins, Entomology.

His recent articles reflect a diverse array of research interests and contributions to the field:

The neonicotinoid acetamiprid is highly toxic to wild non-target insects

Late-instar monarch caterpillars sabotage milkweed to acquire toxins, not to disarm plant defence

Environmental complexity and predator density mediate a stable earwig-woolly apple aphid interaction

Predatory fireflies and their toxic firefly prey have evolved distinct toxin resistance strategies

A simple artificial diet for feeding and sequestration assays for the milkweed bugs Oncopeltus fasciatus and Spilostethus saxatilis

Spatial metabolomics reveal divergent cardenolide processing in the monarch (Danaus plexippus) and the common crow butterfly (Euploea core)

No physiological costs of dual sequestration of chemically different plant toxins in the milkweed bug Spilostethus saxatilis (Heteroptera: Lygaeidae)

Antioxidant availability trades off with warning signals and toxin sequestration in the large milkweed bug (Oncopeltus fasciatus)
