白僵菌对西花蓟马若虫的致病力和对巴氏钝绥螨的影响
Virulence of Beauveria bassiana Isolates against the First Instar Nymphs of Frankliniella occidentalis and Effects on Natural Enemy Amblyseius barkeri
摘要
Abstract
Virulence of five Beauveria bassiana isolates against the first instar nymph ofFrankliniella oceidentalis was evaluated in this study. Three isolates TL^-7, SZ%-15 and RSB were highly virulent to the first instar nymph with 90.8%, 92.5% and 100% mortality at the dose of 1 ×^108 conidia-mL-1, respectively. Among the five isolates, isolate RSB was the most virulent, with LTs0value of 2.383 d and LCs0value of 1.53 × 103 conidia.mL-1. The non-target effects of RSB on Amblyseius barkeri, an important predator ofF. occidentalis, were investigated. Results showed that RSB （ 1 × 10^7 conidia .mL-^1 ）-treated A. barkeri could develop into adult stage. RSB did not significantly reduce the development duration, fecundity and longevity of A. barkeri compared to control, with the development duration of 5.9 d, fecundity of 33.850 d and longevity of 1.78 individual, indicating that the isolate RSB had no significant negative effects on the non-target predator A. barkeri. All the data above suggested that B. bassiana combined used with A. barkeri would be potential for the control ofF. occidentalis under field conditions.关键词
