摘要
微红梢斑螟(Dioryctria rubella Hampson)幼虫危害松树主梢,并且由于其具有隐蔽性,一般药物无法直接作用于幼虫虫体。研究在筛选出高效渗透剂的基础上,采用"药剂+渗透剂"的组合,进行了微红梢斑螟的化学防治研究。结果表明:渗透剂明显增加了化学药剂的防治效果,其中"甲维盐+柔脂通"组合防治效果最好,施药60d后新梢受害率仅为1.13%,被害率减退率达到了89.32%,防治效果为85.56%。
The larvae of Dioryctria rubella damage the main shoots of pine trees,and because of their hidden nature,general drugs cannot act directly on the larvae.In this study,the chemical control of Dioryctria rubella was carried out based on the screening of highly effective penetrators and the combination of"pesticide+penetrant".The results showed that the penetrant significantly increased the control effect of chemical agents,among which the combination of"emamectin+Rouzhitong"had the best control effect,and the new shoot damage rate was only 1.13%after 60 days of application,decrease rate of damage rate reached 89.32%,and the control effect was 85.56%.
