Black soldier fly (Hermetia illucens (Linnaeus, 1758)) larvae inhibit oviposition of house fly (Musca domestica Linnaeus, 1758) by releasing a semiochemical, although in some situations, inhibition is only partial. We hypothesized that there is a certain period in the life cycle of black soldier fly when it can cause antibiosis of the house fly. Choice and non-choice tests were used to separately examine the effectiveness of each developmental stage of black soldier fly (egg, larval (phase I, II, and III), prepupal and pupal stages) and crude extract of larvae on house fly oviposition. Tests using each developmental stage were compared with controls lacking black soldier fly. The effects of black soldier fly on the number of newly hatched house fly larvae were evaluated and there was a significant difference between the test and control in the number of eggs laid by house fly for all phases of the black soldier fly larval stage. Strong inhibition was found in some black soldier fly larval phases. Significant differences in the numbers of house fly eggs oviposited in food containers treated with crude extract were found when compared with a control, confirming that chemicals from black soldier fly larvae resulted in inhibition of oviposition of house fly. The results from experiment also indicated that chemicals from black soldier larvae influenced the number of house fly larvae newly hatched from eggs.
黑蝇幼虫（Hermetia illucens（Linnaeus，1758））通过释放信息素来抑制家蝇（Musca domestica Linnaeus，1758）的产卵，尽管在某些情况下，抑制作用只是部分的。我们假设黑蝇幼虫在其生命周期的某个特定阶段可以对家蝇产生抗菌作用。选择和非选择试验分别用于检查黑蝇幼虫（卵、幼虫（I、II 和 III 期）、预蛹和蛹期）和幼虫粗提物对家蝇产卵的有效性。用每个发育阶段进行的测试与缺乏黑蝇的对照进行了比较。评估了黑蝇对新孵化的家蝇幼虫数量的影响，在黑蝇幼虫的所有阶段，家蝇产卵的数量在测试和对照之间存在显著差异。在一些黑蝇幼虫阶段发现了强烈的抑制作用。与对照相比，用粗提取物处理的食物容器中家蝇产卵的数量存在显著差异，证实了黑蝇幼虫的化学物质导致了家蝇产卵的抑制。实验结果还表明，黑蝇幼虫的化学物质影响了从卵中新孵化的家蝇幼虫的数量。
