| 为筛选出能有效防治橘小实蝇的药剂, 采用药膜法测定16种药剂对橘小实蝇成虫的触杀毒力, 同时测定了田间种群对6种药剂的抗性水平。结果表明, 处理24 h后各供试药剂的毒力大小依次为:毒死蜱>甲维盐>辛硫磷>马拉硫磷>高效氯氰菊酯>噻虫胺>呋虫胺>乙基多杀菌素>多杀霉素>噻虫嗪>氰戊菊酯>溴氰菊酯>阿维菌素>氯氰菊酯>虫螨腈>杀虫单。抗生素类药剂随着时间的延长, 触杀活力明显提高。田间抗药性检测结果显示, 广西4个地区的橘小实蝇均对高效氯氰菊酯产生了中等抗性, 玉林和桂林地区种群对阿维菌素也达到中抗水平。本试验明确了多种杀虫剂对橘小实蝇的毒力和田间抗性水平, 可为化学防治橘小实蝇提供参考。 |
| 英文摘要: |
| In order to get effective and safe insecticides for controlling oriental fruit fly, dry residue film bioassay method was used to test the toxicity of 16 insecticides to the adults of susceptible strain of Bactrocera dorsalis (Hendel). Resistance of field populations of B.dorsalis from Guangxi to six insecticides was also determined simultaneously by vial residue analysis in the laboratory. The results showed that the toxicity of sixteen insecticides to B.dorsalis adults from high to low was as follows: chlorpyrifos, emamectin benzoate, phoxim, malathion, β-cypermethrin, clothianidin, dinotefuran, spinetoram, spinosad, thiamethoxam, fenvalerate, deltamethrin, abamectin, cypermethrin, chlorfenapyr and monosultap. However, with the extension of time, the contact toxicity of antibiotic insecticide was obviously increased. Resistance test demonstrated that four field populations of B. dorsalis were all showed mid-resistance to beta-cypermethrin, and Yulin and Guilin populations also showed mid-resistance to abamectin. The results provide a guidance for chemical control against the pest. |
