In trapping programs prior capture of individuals of the same or different species may influence subsequent attractiveness of the trap. To evaluate this process with stored-product insects, the effect of the presence of dead or alive adults in traps on the behavioral responses of six stored-product insect species, Tribolium confusum Jacquelin du Val, T. castaneum (Herbst) (Coleoptera: Tenebrionidae), Sitophilus oryzae (L.), S. granarius (L.) (Coleoptera: Curculionidae), Oryzaephilus surinamensis (L.) and O. mercator (Fauvel) (Coleoptera: Silvanidae), was studied in choice tests under laboratory conditions. Two series of tests were carried out. In the first series, the choice was between either alive or dead adults of same species and blank (no adults). Overall, dead adults had the strongest influence, increasing the response of S. oryzae, S. granarius, O. surinamensis, and O. mercator and decreasing the response of the two Tribolium species. Presence of alive adults generally did not result in a response different from blank, except for T. castaneum and O. surinamensis that had a reduced response. In the second series of tests, the choice was between alive or dead individuals of the species vs. alive or dead individuals of its relative cogeneric species. For choices between alive individuals, S. oryzae, S. granarius, and O. surinamensis showed a preference for alive individuals of the same species vs. the cogeneric species, and for all the other species there was no preference. For choices between dead individuals, T. castaneum exhibited a preference for individuals of the same species, while S. oryzae, S. granarius, and O. mercator showed a preference for individuals of the cogeneric species, and all other combinations did exhibit a preference. Our results suggest that traps containing alive and dead individuals of the same and other species can seriously affect the response and capture of additional insects.
在诱捕程序中，先前捕获的同种或不同种个体可能会影响诱捕器随后的吸引力。为了用储粮害虫评估这一过程，研究了诱捕器中死成虫或活成虫的存在对六种储粮害虫行为反应的影响，这六种害虫分别是杂拟谷盗（Tribolium confusum Jacquelin du Val）、赤拟谷盗（T. castaneum (Herbst)）（鞘翅目：拟步甲科）、米象（Sitophilus oryzae (L.)）、谷蠹（S. granarius (L.)）（鞘翅目：象甲科）、锯谷盗（Oryzaephilus surinamensis (L.)）和长角扁谷盗（O. mercator (Fauvel)）（鞘翅目：扁甲科），研究是在实验室条件下的选择试验中进行的。进行了两个系列的试验。在第一个系列中，选择是在同种的活成虫或死成虫与空白对照（无成虫）之间进行。总体而言，死成虫的影响最大，增加了米象、谷蠹、锯谷盗和长角扁谷盗的反应，降低了两种拟谷盗的反应。活成虫的存在通常不会导致与空白对照不同的反应，除了赤拟谷盗和锯谷盗的反应有所降低。在第二个系列的试验中，选择是在该物种的活个体或死个体与同属近缘物种的活个体或死个体之间进行。对于活个体之间的选择，米象、谷蠹和锯谷盗表现出对同种活个体而非同属近缘物种活个体的偏好，而对于所有其他物种则没有偏好。对于死个体之间的选择，赤拟谷盗表现出对同种个体的偏好，而米象、谷蠹和长角扁谷盗表现出对同属近缘物种个体的偏好，所有其他组合均未表现出偏好。我们的结果表明，含有同种和其他物种活个体和死个体的诱捕器会严重影响对其他昆虫的反应和捕获。
