中文摘要:
      异色瓢虫 Harmonia axyridis (Pallas) 是一种重要的天敌昆虫, 在田间应用时常会受到施用药剂的影响。为了解浙江地区常用杀菌剂对异色瓢虫的影响, 本文选用该地区田间15种常用杀菌剂, 采用喷雾法, 在实验室条件下测定了其对异色瓢虫2龄和4龄幼虫、蛹以及成虫的影响。结果显示:不同杀菌剂对异色瓢虫不同虫态有不同程度的影响, 但大多数杀菌剂对异色瓢虫相对安全。60%唑醚·代森联 WG、50%异菌脲 SC、99%矿物油 EC、43%氟菌·肟菌酯 SC、42.4%唑醚·氟酰胺 SC对异色瓢虫2龄幼虫影响较大, 其中42.4%唑醚·氟酰胺 SC对异色瓢虫2龄幼虫影响最大, 平均校正死亡率最高达到93.22%。30%氧氯化铜 SC、1亿cfu/g 枯草芽孢杆菌 CG、0.5%几丁聚糖 AS、42.4%唑醚·氟酰胺 SC、40%噻唑锌 SC对异色瓢虫蛹有一定程度的影响, 其中40%噻唑锌 SC对异色瓢虫蛹的影响最大, 平均校正死亡率达到31.04%。试验的15种杀菌剂对异色瓢虫4龄幼虫和成虫相对安全, 平均校正死亡率皆小于21%。从安全性考虑, 当异色瓢虫处于2龄幼虫阶段时, 不建议使用60%唑醚·代森联WG、50%异菌脲 SC、99%矿物油 EC、43%氟菌·肟菌酯 SC、42.4%唑醚·氟酰胺 SC。当异色瓢虫处于4龄幼虫、蛹和成虫时, 15种供试杀菌剂都比较安全, 使用时可选用对其影响较小的杀菌剂。
英文摘要:
      Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) is an important natural enemy, and its application in the field is often affected by the pesticides. To clarify the effects of commonly used fungicides on H.axyridis in Zhejiang area, the effects of fifteen fungicides on the second-instar larvae, the fourth-instar larvae, pupae and adults of H.axyridis were examined by spray method under laboratory conditions. The results showed that different fungicides had different effects on different stages of H.axyridis, and most of the fungicides were relatively safe to H.axyridis. Pyraclostrobin·metiram 60% WG, iprodione 50% SC, petroleum oil 99% EC, fluopyram·trifloxystrobin 43% SC and pyraclostrobin·fluxapyroxad 42.4% SC had high effects on the second-instar larvae of H.axyridis, and pyraclostrobin·fluxapyroxad 42.4% SC had the highest effect on the second-instar larvae of H.axyridis, with average corrected mortality of 93.22%. Copper oxychloride 30% SC, Bacillus subtilis 1×108 cfu/g CG, chltosan 0.5% AS, pyraclostrobin·fluxapyroxad 42.4% SC and zinc thiazole 40% SC had some effects on the pupae of H.axyridis, among which zinc thiazole SC 40% had the highest effect on the pupae of H.axyridis, with average corrected mortality of 31.04%. In general, the tested fifteen fungicides were relatively safe to the fourth-instar larvae and adults of H.axyridis, and the average corrected mortality was less than 21%. Considering the safety of fungicides to H.axyridis, it is not recommended to use pyraclostrobin·metiram 60% WG, iprodione 50% SC, petroleum oil 99% EC, fluopyram·trifloxystrobin 43% SC, pyraclostrobin·fluxapyroxad 42.4% SC when it is at the second-instar stage. The fifteen tested fungicides were all safe to the fourth-instar larvae, pupae and adults of H.axyridis, and the one with little effect could be used.
