摘要
通过药效试验对农保乐、农哈哈杀虫素、杀虫单、毒死蜱、功夫、灭扫利和万灵轮用在大田中防治香瓜上美洲斑潜蝇的效果和对天敌的影响进行了评价。结果表明：农保乐、农哈哈杀虫素、毒死蜱、功夫、灭扫利和万灵轮用处理的平均校正防治效果分别是９０．８９％、８９．８５％、８４．９５％、８４．３５％、７３．７６％和５６．７８％，防治收益分别为４３０６．４０、４２７１．１０、３７８３．８０、３７２２．２０、２２９４．６０和１３４６．２０元／ｈｍ２。同时，农保乐和农哈哈杀虫素对美洲斑潜蝇主要寄生天敌釉姬小蜂Ｃｈｒｙｓｏｃｈａｒｉｓｓｐ．、新釉姬小蜂Ｎｅｏｃｈｒｙｓｏｃｈａｒｉｓｓｐ．和潜蝇茧蜂Ｏｐｉｕｓｓｐ．较安全。
The field experiments were conducted to determine the feasibility of using Nongbaole, Jieyangmygin, Chlorpyrifos, Mehypo, Cyhalothrin, Fenpropathrin which had been applied in an alternation of Methomyl for controlling the vegetable leafminer, Liriomyza sativae Blachard on Cucumis melo L. in 1997 in Guangdong Province. The results showed that Nongbaole, Jieyuangmygin, Chlorpyrifos, Mehypo, Cyhalothrin, Fenpropathrin which had been appolied in an alternation of Methomyl gave a control efficiency 89.85%, 84.35%, 73.76% and 56.78% respectively. The control economic profit recorded from those insecticidetreated plot were 4306.40, 4271.10, 3783.80, 3722.20, 2294.60 and 1346.20 yuan (RMB) per hm 2. Nongbaole and Jieyangmygin were found to be safer to Chrysocharis sp., Neochryocharis sp. and Opius sp., hymenopterous parasites as the most important natural enemies of vegetable leafminer Liriomyza sativae Blanchard.
