Compatibility of the Turkish entomopathogenic nematode isolates Steinernema feltiae (Filipjev) and Heterorhabditis bacteriophora (Poinar) with six chemical pesticides registered for vegetable crops in Turkey was investigated. Mortality, infectivity, and reproduction capacity of pesticide-treated EPNs have been assessed. Our study indicated that imidacloprid and cyflumetofen showed no adverse effect on the survival, infectivity, and reproduction rates of EPNs and can be considered as the most compatible pesticides. The fungicides, fluxapyroxad + difenoconazole and ametoctradin + dimethomorph, caused significantly higher mortality on S. feltiae; however, only fluxapyroxad + difenoconazole showed the negative effect on the survival of H. bacteriophora. Although spiromesifen, spinosad and fluxapyroxad + difenoconazole treated H. bacteriophora had significantly lower reproduction capacity, no negative effect has been observed on the progeny production of S. feltiae among the tested pesticides. In this study, compatibility of cyflumetofen, fluxapyroxad + difenoconazole and ametoctradin + dimethomorph with EPNs have been reported for the first time. The results of the present study will contribute to cost-effective and sustainable management of vegetable pests.

在实验室条件下，昆虫病原线虫与蔬菜作物中注册的农药的相容性

研究了土耳其昆虫病原线虫分离株Steinernema feeliae（Filipjev）和Heterorhabditis bacteriophora（Poinar）与在土耳其注册的用于蔬菜作物的六种化学农药的相容性。已评估了农药处理的EPN的死亡率，传染性和繁殖能力。我们的研究表明吡虫啉和氟氰菊酯对EPNs的存活，感染性和繁殖率均无不利影响，可以被认为是最相容的农药。杀真菌剂fluxapyroxad + difenoconazole和阿美替拉丹+ dimethomorph导致了S.感受派的死亡率大大提高。然而，只有fluxapyroxad + difenoconazole对肝癌的生存有负面影响H.细菌。尽管用螺吡西芬，多杀菌素和fluxapyroxad + difenoconazole处理过的H.细菌隐喻具有明显较低的繁殖能力，但在所测试的农药中，未观察到对S. feeliae的后代产生负面影响。在这项研究中，首次报道了氟苯乙芬，氟哌啶虫酰胺+联苯达康唑和阿米卡丁+二甲基吗啡与EPN的相容性。本研究的结果将有助于经济有效地和可持续地管理蔬菜害虫。
