摘要

摘要: 目的木瓜秀粉蚧Paracoccus marginatus Williams and Granara de Willink是我国一种重要的新入侵害虫，为筛选出防治木瓜秀粉蚧的高效药剂，明确其对不同杀虫剂的敏感性。方法采用浸叶法测定了2龄若虫和雌成虫对15种常用杀虫剂的敏感性。结果从15种药剂中筛选出5种对木瓜秀粉蚧毒力较高的杀虫剂，分别为25 g·L⁻¹高效氯氟氰菊酯乳油、10%虫螨腈悬浮剂、4.5%高效氯氰菊酯乳油、15%哒螨灵水乳剂和15%唑虫酰胺悬浮剂；其中，25 g·L⁻¹高效氯氟氰菊酯乳油对木瓜秀粉蚧的致死中浓度（LC₅₀）最小，2龄若虫和雌成虫的致死中浓度LC₅₀分别为0.243 0 、0.782 1 mg·L⁻¹，其次为10%虫螨腈悬浮剂、4.5%高效氯氰菊酯乳油和15%哒螨灵水乳剂，15%唑虫酰胺悬浮剂的LC₅₀值最大；木瓜秀粉蚧2龄若虫对药剂的敏感性明显高于雌成虫。结论就生物活性测定而言，在木瓜秀粉蚧爆发时，可选用25 g·L⁻¹高效氯氟氰菊酯乳油、10%虫螨腈悬浮剂、4.5%高效氯氰菊酯乳油、15%哒螨灵水乳剂和15%唑虫酰胺悬浮剂作为当前防治木瓜秀粉蚧的主要防治药剂，可有效遏制入侵害虫木瓜秀粉蚧的危害。

Abstract: Objective Tests to screen and determine sensitivities of insecticides for controlling Paracoccus marginatus Williams and Granara DE Willink, an important new invasive pest on papaya plants in China, were conducted. Method The sensitivities of 2^nd nymphs and female adults of P. marginatus to 15 insecticides were determined by means of leaf immersion for pesticide selection. Result Five applications of pesticides including 25 g·L⁻¹L lambda-cyhalothrin SC, 10% chlorfenapyr SC, 4.5% beta-cypermethrin EC, 15% pyridaben EW, and 15% tolfenpyrad SC with high toxicity to P. marginatus were selected for further evaluation. Among them, the lethal medium concentration (LC₅₀) of 25 g·L⁻¹ lambda-cyhalothrin SC was the lowest with LC₅₀ on the 2^nd nymphs and female adults being 0.243 0 mg·L⁻¹ and 0.782 1 mg·L⁻¹, respectively. It was followed by 10% chlorfenapyr SC, 4.5% beta-cypermethrin EC, 15% pyridaben EW and 15% tolfenpyrad SC in that order. The 2^nd nymphs were significantly more sensitive to the insecticides than the female adults. Conclusion It appeared that 25 g·L⁻¹ lambda-cyhalothrin SC, 10% chlorfenapyr SC, 4.5% beta-cypermethrin EC, 15% pyridaben EW or 15% tolfenpyrad SC could be used to control or prevent a P. marginatus outbreak.
