The mite Tetranychus urticae Koch is an important pest on several agricultural crops. Resistance to synthetic pesticides has encouraged evaluating more sustainable control strategies. We evaluated the predatory mites Phytoseiulus persimilis Athias Henriot and Neoseiulus californicus McGregor alone or as vectors of entomopathogenic fungi on the mortality of T. urticae. We estimated the susceptibility of the predatory mites and T. urticae to infection by Metarhizium anisopliaesensu stricto (s. str.) (Metchnikoff) Sorokin, Beauveria bassianas. str. Bals. Vuill, Akanthomyces lecanii (Zimm.) Spatafora, Kepler & B. Shrestha and Cordyceps fumosorosea (Wize) Kepler, B. Shrestha & Spatafora. Then, we determined the mortality of T. urticae due to the two predatory mites alone or in combination with the four fungal isolates. T. urticae was more susceptible to fungi than the predatory mites. B. bassiana and M. anisopliae isolates caused the greatest mortality. Greater mortality of T. urticae was achieved when predatory mites were vectoring B. bassiana or M. anisopliae conidia. Combining predatory mites and entomopathogenic fungi has potential for the control of T. urticae.

捕食性螨（Acari：Phytoseiidae）与昆虫病原真菌在铁叶螨中的相互作用

螨Tetranychus urticae Koch是几种农作物的重要害虫。对合成农药的抵抗力鼓励评估更可持续的控制策略。我们评估了捕食螨Phytoseiulus螨阿蒂亚斯亨里厄特和香瓜小新加利福尼亚小单独或作为对死亡率昆虫病原真菌的载体麦格雷戈T.螨。我们估计捕食螨和易感性T.螨的感染绿僵菌狭义（第海峡）（Metchnikoff）索罗金，白僵菌秒。海峡。巴尔。Vanill，Akanthomyces lecanii（Zimm。）Spatafora，Kepler和B. Shrestha和冬虫夏草（Wize）Kepler，B。Shrestha和Spatafora。然后，我们确定了单独的两种捕食性螨或与四种真菌分离物结合导致的荨麻疹的死亡率。荨麻疹比掠食性螨更容易感染真菌。B. bassiana和M. anisopliae菌株引起最大的死亡率。当掠食性螨虫感染球孢杆菌或拟南芥分生孢子时，荨麻疹的死亡率更高。结合捕食螨和昆虫病原真菌有控制荨麻疹的潜力。
