虽然昆虫捕食者[Feltiella acarisuga（Vallot），Scolothrips takahashiPriesner，Oligotaspp.和Stethorusspp.]在控制蜘蛛螨方面发挥作用，在野外条件下很难直接收集昆虫捕食者。为了证明植物陷阱收集捕食者的适用性，我们调查了盆栽小松菜（Brassica rapaL.）和菜豆（Phaseolus vulgarisL.）二斑叶螨（Tetranychus urticaeKoch）的寄生植物，分别作为新型和常规植物诱捕器，用于收集活体捕食性昆虫。大量的捕食者被发现在这些陷阱放置在一个Puerariamontanavar.lobata（Willd.）Sanjappa和Pradeep]，尽管在杂草群落中肉眼观察到低密度。在小松纲诱捕器上采集的存活率（99.5- 100%）显著高于用菜豆诱捕器采集的存活率（26.6- 61.1%），这是由于捕食者被菜豆叶片上的钩状毛状体诱捕所致。这些结果表明，小松纲陷阱是适合收集活的昆虫捕食者，即使捕食者很少或无法直接在肉眼下观察到。我们还表明，小松纳陷阱是有效的收集寄生蜂（Aphanogmussp.）关闭.真螨
Although insect predators [Feltiella acarisuga(Vallot),Scolothrips takahashiiPriesner,Oligotaspp. andStethorusspp.] play a role in controlling spider mites, it is difficult to collect insect predators directly under field conditions. To prove the suitability of a plant trap for collecting the predators, we investigated the efficiency of potted komatsuna (Brassica rapaL.) and kidney-bean (Phaseolus vulgarisL.) plants inhabited byTetranychus urticaeKoch, using as novel and conventional plant traps respectively, for collecting living insect predators. Large numbers of predators were found on these traps placed in a kudzu vine community [Puerariamontanavar.lobata(Willd.) Sanjappa and Pradeep] despite being observed in low densities under the naked eye in the weed community. Significantly higher survival rates (99.5–100 %) were obtained when collecting them from komatsuna traps than those (26.6–61.1 %) obtained with kidney-bean traps due to predators’ entrapment by the hooked trichomes on bean leaves. These results indicate that the komatsuna trap is suitable for collecting living insect predators, even when predators are rarely or not observed directly under the naked eye. We also showed that the komatsuna trap is effective for collecting a parasitoid (Aphanogmussp.) ofF. acarisuga.
