Sometimes, less is more. Case in point: the mass-rearing program that produces millions of sterile Mexican fruit flies (Anastrepha ludens) for managing wild populations. Scientists refining the effort find that a lower ratio of males to females in mating cages leads to higher fecundity and fertility in the females—and higher cost-effectiveness for the operation.
LeafByte is a free, open-source mobile app for quickly measuring leaf damage caused by herbivorous insect pests. If you've ever considered building a mobile app to aid in your research, here's a first-hand account from the Cornell entomology student who took LeafByte from idea to action.
By using the brown marmorated stink bugs' own aggregation pheromone, the pests can be lured into a condensed area, thereby reducing the area that a grower must spray with insecticide. A two-year study in apple orchards suggests the method could soon become economically feasible.
Boric acid dust is a common tool in urban pest management, but a new study shows external exposure is minimally effective against bed bugs. When bed bugs ingest boric acid, though, few survive.
