| Resumo: |
Traps baited with synthetic pheromones for either Podisus nigrispinus (Dallas) or Supputius cincticeps (Stäl) were field tested at the Universidade Federal de Viçosa, Minas Gerais, Brazil, beginning September 7, 1995. No P. nigrispinus were caught but, in September and October, several adult males and females of P. distinctus (Stäl) were caught along with a few adults of S. cincticeps and two females of a tachinid fly parasitoid, Cylindromyia atra Roeder. Chemical analysis of the pheromone gland extract of P. distinctus males indicated that this species produces a pheromone containing the major compounds of P. nigrispinus and S. cincticeps. Therefore, on November 6 a set of traps was baited with the pheromones of both P. nigrispinus and S. cincticeps, and monitored in the field until February 6, 1996. During this second phase of the study, six times more P. distinctus were caught in the combined pheromone treatment than in traps baited only with the P. nigrispinus pheromone. The phenology of these neotropical asopines is like that for P. maculiventris (Say) in temperate North América, although fewer predators and host-seeking parasitoids were caught. Suspected pheromones were also identified for P. rostralis (Stäl) from Goiás, Brazil, and P. sagitta (Fabricius) from Honduras. In addition, the chemistry of other exocrine secretions from these neotropical species was investigated.
