Many animal and insect species use Batesian mimicry -- mimicking a poisonous species -- as a defense against predators. The common palmfly Elymnias hypermnestra -- a species of satyrine butterfly that is found throughout wide areas of tropical and subtropical Asia -- adds a twist to this evolutionary strategy.
A new study linking land use patterns and pest outbreaks in Bt maize suggests that slowing the resurgence of western corn rootworm may require a larger-scale strategy than previously thought.
Scientists have used gene-editing advances to achieve a tenfold increase in the production of super-bug targeting formicamycin antibiotics.
Entomologist Akito Kawahara's message is straightforward: We can't live without insects. They're in trouble. And there's something all of us can do to help.
Scientists are combining artificial intelligence and advanced computer technology with biological know how to identify insects with supernatural speed. This opens up new possibilities for describing unknown species and for tracking the life of insects across space and time
Research on cycad trees in Colombia, Guam, and the Philippines has illuminated how knowledge of their branching behavior may benefit conservation decisions for the endangered plants. In a study published in the December issue of the journal Horticulturae, scientists from the University of Guam and the Montgomery Botanical Center in Florida show that the number of times a cycad tree produces a branch can be used to infer the sex of the tree.
A resemblance to moss, lichens and fungi made for fantastic cover by a new genus and species of cylindrical bark beetle described by an Oregon State University College of Science researcher.
Researchers from the University of Hong Kong and Toho University have discovered that predation by snakes is pushing lizards to be active at warmer body temperatures on islands where snakes are present, in comparison to islands free from snakes. The findings show that lizard thermal biology is highly dependent on predation pressures and that body temperatures are rising suggest that such ectothermic predator-prey relationships may be changing under climatic warming.
Scientists have uncovered why a food-ingredient-based pesticide made from safflower and cottonseed oils is effective against two-spotted spider mites that attack over a thousand species of plants while sparing the mites' natural predators.
Bird diets provide a real treasure for research into the distribution and conservation of their prey, conclude scientists after studying the Eurasian Eagle Owl in southeastern Bulgaria. In their paper, published in the open-access, peer-reviewed journal Travaux du Muséum National d'Histoire Naturelle "Grigore Antipa", they report the frequent presence of the threatened Big-Bellied Glandular Bush-Cricket, and conclude that studies on the Eurasian Eagle Owl could be used to identify biodiversity-rich areas in need of protection.
