Gut Check: How Stink Bugs’ Insides Illuminate Their Eating Habits

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.

Researchers Share New Method for Detecting Insect Egg Predators

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.

Psyllid Movements Revealed Via Gut Content Analysis

Tracking the movements of the diminutive pests is a challenge, but a new study shows that DNA analysis of psyllid gut contents can reveal what plants psyllids have fed on, thereby pinpointing the non-crop "whistle stops" psyllids make before infesting crop fields.

Fruit DNA in Invasive Flies’ Guts Could Help Track Their Dispersal

A recent study at North Carolina State University shows that DNA analysis of spotted-wing drosophila (Drosophila suzukii) flies can detect whether they fed on strawberries as much as seven days prior. Researchers hope the proof of concept will lead to more accurate analysis of the invasive pest's dispersal in the field.
