两种不同药剂对松褐天牛飞机防治效果的试验对比

Comparison of the Control Effects of Two Different Insecticides on Monochamus alternatus Hope

试验对比了两种防治松褐天牛的微囊悬浮剂在林间防治效果。结果表明:供试药剂对松褐天牛成虫都有良好的防治效果;2种药剂对比,8%氯氰菊酯触破式微囊悬浮剂(绿雷二代)比3%噻虫啉缓释型微囊悬浮剂表现出更好的速效性、持效性和综合防效的稳定性。为此,提出了相关建议:抓住天牛羽化初期和盛期开展防治;在重点保护区实施喷药防治形成自然隔离带,阻击疫情扩散蔓延;为了防止松褐天牛产生耐药性,交替使用;充分发挥两种药剂的速效性、持效性和综合防效的稳定性等特点,制定科学合理的施药方案;同时加强与有关生产企业和科研院所紧密合作。

In this paper,the control effect of two kinds of Monochamus alternatus Hope microcapsule suspension agents against Longurus pinus was tested in the forest.The results showed that the test agents had good control effect on adult Longurus pinus.Compared with the two agents,the 8%cypermethrin contact microcapsule suspension agent(Green LightningⅡ)showed better rapid,durable and comprehensive control stability than the 3%thiacloprid sustained release microcapsule suspension agent.It is suggested that the prevention and control should be carried out at the early and peak period of Monochamus alternatus Hope emergence.Spraying has been implemented in key protected areas to form natural isolation zones to prevent the spread of the epidemic.In order to prevent the development of drug resistance,the suspension agents should be alternately used;A scientific and reasonable application plan is formulated to give full play to the characteristics of the two kinds of drugs,such as quick action,efficiency and stability of comprehensive control effect;At the same time,close cooperation with related production enterprises and research institutes should be strengthened.
