Mites in the genus Tropilaelaps could follow in the footsteps of Varroa mites as significant threats to honey bees if they were to expand their range. A new test using analysis of the “melt curves” of DNA samples can discern the four known Tropilaelaps species and could be an important tool in surveillance for the mite pests in apicultural settings.
Brown marmorated stink bugs are generalist eaters, and finding them on one plant doesn't mean they haven't also been feeding on another. New research explores the potential of DNA analysis of stink bugs' gut contents to identify the plants they've eaten in the preceding two weeks.
A proof-of-concept study shows insect eggs can be marked with protein that can be later detected in a gut-content analysis of arthropod predators that fed on the eggs. Researchers say the method has applications in biological control and beyond.
A crucial step in management of mosquito-borne diseases is knowing exactly what kind of mosquitoes are present in any given locale. Are they garden-variety species that aren’t carriers of human […]
