Multispecies sex pheromone trapping (trapping of more than one species in the same trap) for the bollworm,Helicoverpa (Heliothis) zea (Boddie); fall armyworm,Spodoptera frugiperda (J.E. Smith); armyworm,Pseudaletia unipuncta (Haworth); and the black cutworm,Agrotis ipsilon (Hufnagel) was evaluated. Baiting of individual traps with all possible combinations of the four species taken two at a time caused a reduction in the catches of at least one of any two species involved when compared to traps baited for only one species. These results demonstrated the species specificity of sex pheromones identified for these species. Although the effects were reduced in some cases, the interaction between species also was observed when adjacent traps were baited with the sex pheromone dispensers of the different species. These results indicate that the spacing between pheromone traps when more than one species are being trapped at the same site affects trap capture and should be evaluated further.
棉铃虫（Helicoverpa （Heliothis）zea（Boddie））、秋粘虫（Spodoptera frugiperda（J.E. Smith））、粘虫（Pseudaletia unipuncta（Haworth））和草地贪夜蛾（Agrotis ipsilon（Hufnagel））的多物种性信息素诱捕（在同一个诱捕器中诱捕超过一个物种）进行了评估。用四种物种的所有可能组合成对诱饵单个诱捕器，与仅用一种物种诱饵的诱捕器相比，至少有两种涉及的物种的捕获量减少。这些结果表明了为这些物种确定的性信息素的物种特异性。尽管在某些情况下效果减弱，但当用不同物种的性信息素释放器对相邻诱捕器进行诱饵处理时，也观察到了物种之间的相互作用。这些结果表明，当在同一地点诱捕多个物种时，性信息素诱捕器之间的间距会影响诱捕器的捕获，应进一步评估。
