几种常用杀虫剂对日本食蚧蚜小蜂的毒性
The Toxicities of Several Common Insecticides on Coccophagus japonicus Compere
摘要
Abstract
Parasaissetia nigra Nietner and Eotetranychus sexmaculatus Riley are two serious pests on rubber tree.To study the coordinating utilizations of insecticides and natural enemies,the toxicities of six common insecticides (miticide) to Coccophagus japonicus Compere were tested by residual film and foliar spray in the laboratory.The results showed that the mortalities of adult parasitoids were all 100％ treated by Buprofezin,Cyhalothrin and Abamectin after 24 hours,but the mortalities was 2.16％ and 17.39％,respectively treated by Spirotetramat and Flonicamid.The order of eclosion rates of the C.japonicus pupa treated by the six pesticides as flows:Flonicamid＞Spirotetramat＞Buprofezin＞Abamectin＞Cyhalothrin＞D eltamethrin.Adults emerging from pupae got the highest life span (23.89 d) under the treatment of 1 500 fold Spirotetramat solution and the lowest life span (0 d) with 1 500 fold Deltamethrin solution.The order of eclosion rates of the C.japonicus old larva treated by six pesticides as flows:Spirotetramat＞Flonicamid＞Deltamethrin＞Abamectin.Adults emerging from old larva got the highest life span (18.8 d) under the treatment of 2 500 fold Flonicamid solution.The order of parasitic rates and fecundities of adult C.japonicus from high to low was Buprofezin Abamectin Cyhalothrin＞Flonicamid＞Spirotetramat＞D eltamethrin.In conclusion,we used the mortality,eclosion rates,life span and fecundity of adult C.japonicus as biological standards and recommended using Flonicamid and Spirotetramat to control P.nigra.关键词
