Anoplius splendens
Anoplius splendens is a spider wasp in the family Pompilidae. Laboratory studies have demonstrated that adult females exhibit olfactory learning behavior, specifically learning to associate the odor of host spider feces with the presence of suitable hosts. This cognitive ability enhances their efficiency in locating host microhabitats. The species was described by Dreisbach in 1949.
Telenomus podisi
Telenomus podisi is an egg parasitoid wasp first described by William Harris Ashmead in 1893. It is a primary natural enemy of stink bugs (Pentatomidae), with Euschistus heros documented as its principal host. The species has been extensively studied for biological control applications in soybean and other agricultural systems, particularly in Brazil. Laboratory studies demonstrate that females can form olfactory memories during immature development, with learned preferences persisting up to 72 hours post-emergence. The species is susceptible to several insecticides including imidacloprid, which is lethal, while some organic products show greater selectivity.
