Efficacy of five selected acaricides against Tetranychus urticae (Acari: Tetranychidae) and their side effects on relevant natural enemies occurring in citrus orchards.

摘要: BACKGROUND: Three groups of natural enemies are fundamental in citrus IPM Spain: coccinellid and phytoseiid predators hymenopteran parasitoids. Tetranychus urticae Koch is an important pest affecting citrus, for which biological control has not yet been achieved; therefore, acaricides commonly used to it. The goal this study was measure the efficacy different on mite their side effects three relevant (Cryptolaemus montrouzieri Mulsant, Neoseiulus californicus McGregor Aphidius colemani Viereck). RESULTS: Some products proved highly effective against T. harmless A. (mineral oil, tebufenpyrad, clofentezine fenazaquin). However, almost all tested were slightly harmful both considered. Fenazaquin even moderately N. californicus. CONCLUSION: Further studies, like that presented here, necessary gain a better understanding integrating chemical controls. When considering beneficial arthropods, best options would seem be mineral tebufenpyrad clofentezine. it urgent complete testing citrus.
