摘要
The synthetic racemic mixture of methyl 2,6,10-trimethyltridecanoate, a component of the male produced pheromone of Euschistus heros (F.) (Heteroptera, Pentatomidae), was attractive to pentatomid species in a field test, using homemade pheromone trap designs. The pentatomid Piezodorus guildinii was caught in high numbers in field traps, during two field experiments, indicating a consistent response of this species to the E, heros pheromone. A correlation was found between the range of insects caught in the pheromone-baited traps and a random sampling method. The synthetic stereoisomeric mixture of methyl 2,6,10-trimethyldodecanoate, a minor component of E. heros pheromone, was also held tested and caught no pentatomids. Egg parasitoids were caught in traps baited with E. heros pheromone, indicating that this pheromone can be exploited as a kairomone. A synchrony in the periodicity of trap catch, between the egg parasitoids and their host, was also recorded.
