Pest infestations in net-houses are not sometimes different from that under open-field conditions, necessitating usage of pesticides. To examine the hypothesis that bioagents may have more potential under restricted plant growing conditions, the predatory potential of green lace wing, Chrysoperla zastrowi sillemi Esben-Peterson (Neuroptera: Chrysopidae) was evaluated against the sucking pests of tomato under screen-house conditions. The rates of release were fixed as 4, 5, and 6 s instar grubs plant−1 and a total of 3 releases were made at 7 days interval, with first release at appearance of the aphid, Myzus persicae (Sulzer) and whitefly, Bemisia tabaci (Gennadius). The pooled data for the years 2018 and 2019 revealed that, the release rates 4, 5, and 6 grubs plant−1 were not statistically different in reducing the population of these pests. The factorial analysis based on the release rate and time of these releases suggested that single release of C. zastrowi sillemi at 4 grubs plant−1 was effective against sucking pests in tomato grown under screen-house conditions.

绿色花边翅膀Chrysoperla zastrowi sillemi（Esben-Peterson）（Neuroptera：Chrysopidae）对吮吸番茄害虫的功效：在保护条件下的评估

网箱中的虫害有时与露天环境下的虫害没有什么不同，因此需要使用农药。为了检验生物制剂在受限的植物生长条件下可能具有更大潜力的假说，对绿色蕾丝翅膀Chrysoperla zastrowi sillemi Esben-Peterson（Neuroptera：Chrysopidae）的捕食潜力在筛选条件下针对番茄的吮吸害虫进行了评估。释放速率固定为4、5和6 s龄幼虫plant-1，并且每隔7天进行3次释放，第一次释放出现在蚜虫Myzus persicae（Sulzer）和粉虱Bemisia的粉虱上。塔巴奇（Gennadius）。2018年和2019年的汇总数据显示，减少这些害虫数量的4、5和6 rub植物的释放速率在统计学上没有差异。
