There can be substantial negative consequences for insects colonizing a resource in the presence of competitors. We hypothesized that bacteria, associated with an oviposition resource and the insect eggs deposited on that resource, serve as a mechanism regulating subsequent insect attraction, colonization, and potentially succession of insect species. We isolated and identified bacterial species associated with insects associated with vertebrate carrion and used these bacteria to measure their influence on the oviposition preference of adult black soldier flies which utilizes animal carcasses and is an important species in waste management and forensics. We also ascertained that utilizing a mixture of bacteria, rather than a single species, differentially influenced behavioral responses of the flies, as did bacterial concentration and the species of fly from which the bacteria originated. These studies provide insight into interkingdom interactions commonly occurring during decomposition, but not commonly studied.
昆虫在有竞争者的情况下占领资源可能会产生实质性的负面影响。我们假设与产卵资源以及在该资源上产卵的昆虫相关的细菌可以作为一种调节随后昆虫吸引力、定殖和潜在物种演替的机制。我们分离和鉴定了与脊椎动物腐肉相关的昆虫相关的细菌，并使用这些细菌来衡量它们对利用动物尸体的成年黑蝇产卵偏好的影响，黑蝇是废物管理和法医学中的重要物种。我们还确定，与使用单一物种相比，使用细菌混合物会对苍蝇的行为反应产生不同的影响，细菌浓度和苍蝇的种类也是如此。这些研究提供了对分解过程中常见但通常未被研究的跨界相互作用的深入了解。
