Worldwide, the potato tuber moth (PTM), (Zeller), is one of the most severe pests affecting potato ( L.), whether in open-air crops or during tuber storage. This work examines the potential control of this pest by two species of predatory mites, (Berlese) and (Berlese), on pest eggs under laboratory conditions. In the two first assays, the acceptance rate of the pest eggs was assessed for each predatory mite. Then, in a third assay, the functional response of was studied. The results showed that did not prey on the pest eggs (number of eggs surviving = 4.33 ± 0.38), whereas did (number of eggs surviving = 0.5 ± 0.5). Likewise, showed a type II functional response when it killed the eggs. The results showed the potential use of as a biological control agent of in potato under storage conditions.
在全球范围内，马铃薯块茎蛾（Phthorimaea operculella ，泽勒）是影响马铃薯（Solanum tuberosum L.）的最严重害虫之一，无论是在露天作物中还是在块茎储存期间。这项工作研究了两种捕食螨，智利小植绥螨（Phytoseiulus persimilis ，贝雷塞）和西方盲走螨（Typhlodromus occidentalis ，贝雷塞）在实验室条件下对害虫卵的潜在控制作用。在前两个试验中，评估了每种捕食螨对害虫卵的接受率。然后，在第三个试验中，研究了智利小植绥螨的功能反应。结果表明，智利小植绥螨不捕食害虫卵（存活卵数 = 4.33 ± 0.38），而西方盲走螨会捕食（存活卵数 = 0.5 ± 0.5）。同样，西方盲走螨在杀死卵时表现出II型功能反应。结果表明西方盲走螨在储存条件下作为马铃薯块茎蛾的生物防治剂具有潜在用途。
