Effects of chlorantraniliprole on predatory capacity of Cyrtorhinus lividipennis ( Hemiptera: Miridae)
摘要
Abstract
Aimed to provide a reference to the chemical and biological control of Nilaparvata lugens (Stal) , the effects of the chlorantraniliprole on the functional response of Cyrtorhinus lividipennis ( Reuter) preying on N. lugens were studied with rice stem dipping method. The results revealed that the functional response models of C. lividipennis preying on N. lugens all conformed to Holling' s type Ⅱ curve after C. lividipennis were pretreated with the labeled dose of chlorantraniliprole ( LDC). However, the parameters in the models had some changes. The instantaneous attacking rate ( a') of C. lividipennis pretreated with the insecticide declined. The handling time (77") on eggs, 1st instar nymphs and 2nd instar nymphs of N. lugens by C. lividipennis nymphs pretreated with LDC was extended by 163.03% , 104.21 % and 95.11% , and 81.97% , 102.45% and 99.52% by C. lividipennis adults pretreated with LDC, respectively. The maximal predatory capacities (Na' ) of C. lividipennis pretreated with the insecticide reduced. The searching efficiency (5) of C. lividipennis pretreated with LDC reduced as compared to that of untreated predators. These results suggest that chlorantraniliprole at labeled dose has harmful influence on the predation of C. lividipennis.关键词
