Chemosterilisation with lufenuron bait stations is a recently developed technique that is being implemented for Ceratitis capitata Wiedemann control. The aim of this work was to evaluate the chemosterilising effect of lufenuron against four economically important Latin American fruit flies species: Anastrepha ludens (Loew.), A. obliqua Macquart, A. serpentina Wiedemann and A. striata Schiner (Diptera: Tephritidae) in order to design a similar strategy for their control.
Sexually mature adults were treated by ingestion with concentrations ranging from 0.1 to 30.0 mg g(-1) of lufenuron in the diet. In addition, conspecific crosses with only one of the sexes being treated (30.0 mg g(-1)) were performed in order to appraise the contribution of each sex to the sterilising effect. In all cases, fecundity was not affected by the treatments, as opposed to fertility where all Anastrepha species studied were significantly affected, although to different extents. The conspecific crosses showed that treated males of A. ludens, A. obliqua and A. serpentina were not able to transmit the sterility to their respective untreated females. Only in the case of A. striata did crossing treated males with untreated females significantly reduced egg hatch.
Although further investigations are required, the present results demonstrate that the use of lufenuron for controlling A. striata could be potentially viable.
使用灭幼脲毒饵站对地中海实蝇进行化学绝育是一种新开发的技术，目前正在用于地中海实蝇的防治。本研究的目的是评估灭幼脲对四种重要的拉丁美洲水果蝇（安氏荔枝实蝇、寡鬃实蝇、黑带实蝇和墨西哥实蝇）的绝育效果，以便为它们的防治设计类似的策略。
性成熟的成虫通过摄入含有 0.1 至 30.0 mg g(-1)灭幼脲的饮食进行处理。此外，还进行了仅用一种性别的同种交配（30.0 mg g(-1))，以评估每种性别对绝育效果的贡献。在所有情况下，处理都没有影响生育力，而所有研究的安氏实蝇物种的繁殖力都受到显著影响，尽管程度不同。同种交配表明，处理后的 A. ludens、A. obliqua 和 A. serpentina 雄性无法将不育性传递给它们各自的未处理雌性。只有在 A. striata 中，处理后的雄性与未处理的雌性交配才会显著降低卵孵化率。
尽管需要进一步的研究，但目前的结果表明，使用灭幼脲来控制 A. striata 可能是可行的。
