ABSTRACT

The Sterile Insect Technique (SIT) is a method of pest control used in the management of Ceratitis capitata (Medfly). This technique is based on the mating and transfer of ejaculate sperm to the wild female population from released sterile males. This transfer will induce sterility in the female through sperm dominant lethal mutations. Consequently, the factors influencing sperm transfer and sperm storage are issues that must be understood to enable successful SIT implementation. Age, size, nutritional status, copula duration, and irradiation are the most important factors that affect sperm transfer and storage. Inconsistent results from studies investigating the influence of these factors on sperm transfer/storage may be due to, the strain of fly studied and variability in the sexual experience of the flies used. In this review, we highlight the interaction between these factors, issues that still need to be addressed, and propose future directions for the improvement of medfly males’ sexual performance and the successful application of SIT against this pest.

摘要

无菌昆虫技术（SIT）是一种用于控制人形角膜炎的害虫控制方法。（Medfly）。该技术基于将精子从已释放的不育雄性中交配并转移到野生雌性种群中。这种转移将通过精子显性致死突变诱导雌性不育。因此，影响精子转移和精子存储的因素是必须成功理解才能成功实施SIT的问题。年龄，大小，营养状况，系膜持续时间和辐照是影响精子转移和储存的最重要因素。研究这些因素对精子转移/贮藏的影响的研究结果不一致，可能是由于所研究的苍蝇的应变以及所用苍蝇的性经验的差异所致。在这篇评论中，我们重点介绍了这些因素之间的相互作用，这些问题仍然需要解决，
