We tested the predatory capacity of newly-hatched or newly-molted (Banks) and (Hagen) larvae after a 24 h fasting period on adults of (Pergande) that were feeding on tomato plants (at vegetative and blooming stage) under glasshouse conditions. We also recorded fruit damage by the thrips. Both spp. depredated a similar number of (thrips) adults regardless of the phenological stage of the plant. Second and third instar larvae of both species consumed significantly more thrips than first instar during plant blooming, however when the plant was at vegetative stage, all larval stages of both species predated a similar number of thrips. A significantly lower fruit damage percentage was recorded at the blooming plant when larvae were in the experimental cage, however the presence of second and third instar of both species significantly reduced the fruit damage. No foliar damage was recorded. As far as we know, this is the first assessment of the predatory capacity of and on thrips feeding on tomato under glasshouse conditions.
我们测试了在温室条件下，经过24小时禁食期后，新孵化或新蜕皮的（班克斯）和（哈根）幼虫对以番茄植株（处于营养期和开花期）为食的（佩尔甘德）成虫的捕食能力。我们还记录了蓟马造成的果实损害情况。两种（捕食者）捕食的（蓟马）成虫数量相似，与植株的物候期无关。在植株开花期间，两种物种的二龄和三龄幼虫捕食的蓟马明显多于一龄幼虫，然而当植株处于营养期时，两种物种的所有幼虫阶段捕食的蓟马数量相似。当（捕食者）幼虫置于实验笼中时，开花植株上记录到的果实损害百分比显著降低，然而两种物种的二龄和三龄幼虫的存在显著降低了果实损害。未记录到叶片损害。据我们所知，这是首次在温室条件下评估（捕食者）对取食番茄的蓟马的捕食能力。
