| The response of Cosmopolites sordidus (Germar, 1824) to the volatiles of its host banana plant (Musa paradisiaca cv. Prata) and conspecific adults was studied. In olfactometer, the attraction of males and females of C. sordidus to rhizome and pseudotem of the banana, fresh or rotting, was observed. The results suggested that the aggregation pheromone is produced by males and that it attracts both sexes, and that there is another pheromone produced by females which attracts males only. The results also suggest that the females are the first responsible for the aggregation of the species, but the male pheromone is mainly responsible for the mass aggregation. Nevertheless, the aggregation phenomenon is a consequence of the mutual action of both pheromones... |

| 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... |
