The objective of this study was to evaluate the oviposition rate and the survivorship of some of the most common predators on plants of the natural vegetation of southeastern Brazil, when confined with different food sources. Forty-four laboratory tests were carried out, each corresponding to a different combination of predator species and food source. The predators tested were: Phytoseiidae--Amblyseius acalyphus, Euseius citrifolius, Iphiseiodes zuluagai, Metaseiulus (Metaseiulus) camelliae, Typhlodromips cananeiensis; Stigmaeidae--Agistemus floridanus, Zetzellia malvinae; Tydeidae--Pronematus sp. For most predators, the highest oviposition rate and survivorship were obtained when the prey was one of the tenuipalpid mites, Brevipalpus phoenicis or Tenuipalpus heveae. With the exception of A. floridanus, the predators had low oviposition rate and survivorship on Calacarus heveae relative to their respective rate on other food sources. Predators had also generally low oviposition rate and survivorship when feeding on Tetranychus urticae, Oligonychus gossypii or Frankliniella sp.
本研究的目的是评估巴西东南部自然植被植物上一些最常见捕食者在被限制于不同食物来源时的产卵率和存活率。进行了44次实验室测试，每次测试对应捕食者物种和食物来源的不同组合。所测试的捕食者有：植绥螨科——钝绥螨、酸橙真绥螨、祖氏植绥螨、茶短须螨、卡氏盲走螨；长须螨科——弗氏长须螨、锦葵长须螨；跗线螨科——原跗线螨属。对于大多数捕食者而言，当猎物为细须螨科的茶短须螨或橡胶细须螨时，产卵率和存活率最高。除弗氏长须螨外，相对于在其他食物来源上的相应比率，捕食者在橡胶刺叶螨上的产卵率和存活率较低。捕食者以二斑叶螨、棉叶螨或花蓟马属为食时，产卵率和存活率通常也较低。
