摘要: 【目的】明确巴氏新小绥螨(Neoseiulus barkeri)高效氯氟氰菊酯抗、敏性品系对二斑叶螨(Tetranychus urticae)的捕食功能,探究防治潜力。【方法】在实验室条件下以观察小室法测定巴氏新小绥螨高效氯氟氰菊酯抗、敏品系雌成螨对二斑叶螨3个发育阶段(卵、若螨、成螨)的捕食功能及搜寻效应。【结果】巴氏新小绥螨高效氯氟氰菊酯抗、敏品系对二斑叶螨的捕食功能类型均为Holling-Ⅱ型,且对二斑叶螨卵、若螨和成螨的捕食量变化趋势相同,均随着猎物密度增长而增加,捕食量达到最大后趋于平衡。巴氏新小绥螨抗性品系对二斑叶螨卵和成螨的处理时间分别为0.017 7 d和0.026 9 d,均短于敏感品系(0.018 8 d和0.029 5 d);攻击速率分别为2.253 6和1.158 6,均快于敏感品系(2.302 9和1.629 2)。巴氏新小绥螨抗高效氯氟氰菊酯品系对二斑叶螨卵和成螨的捕食能力(a/Th)和搜寻效应较敏感品系更优。【结论】巴氏新小绥螨高效氯氟氰菊酯抗药性品系对二斑叶螨卵和成螨有非常好的捕食能力,可与减量化学药剂共同应用于田间防治二斑叶螨。

Abstract: 【Objectives】To clarify the predatory function of Neoseiulus barkeri lambda-cyhalothrin resistant and susceptible strains on Tetranychus urticae and explore its potential for prevention and control.【Methods】The predatory function and searching efficiency of lambda-cyhalothrin resistance and sensitive strains of Neoseiulus barkeri female adult mite against Tetranychus urticae eggs,nymphs and adult mites were determined by observation units methods under laboratory conditions.【Results】The predatory function types of the lambda-cyhalothrin resistance and sensitive strains of Neoseiulus barkeri against Tetranychus urticae were all Holling-II,and the predation amount of eggs,nymphs and adult mites of Tetranychus urticae had the same change trend,which increased with the increase of prey density,and the predation amount reached the maximum and then tended to be balanced. The handling time of the resistant strain to Tetranychus urticae eggs and adult mites was 0.017 7 d and 0.026 9 d respectively,which were shorter than the sensitive strain(0.018 8 d and 0.029 5 d);and the attack rates were 2.253 6 and 1.158 6,respectively,which were faster than the sensitive strain(2.302 9 and 1.629 2). The predation ability(a/Th) and searching efficiency of the resistance strain to Tetranychus urticae eggs and adult mites were better than the sensitive strain.【Conclusion】The lambda-cyhalothrin resistant strain of Neoseiulus barkeri has very good predation ability to Tetranychus urticae eggs and adult mites,and can be used together with reducing chemicals to control Tetranychus urticae in the field.
