摘　　要：为筛选棉田主要盲蝽——绿盲蝽Apolygus lucorum和中黑盲蝽Adelphocoris suturalis高效、环境友好的新型防治技术,选择盲蝽科昆虫寄主植物——韭菜Allium tuberosum和向日葵Helianthus annuus种子,采用冷浸法制备其乙醇提取物,利用三臂嗅觉仪比较绿盲蝽对2种提取物和棉花叶片间的嗅觉反应,并筛选了1种具有显著协同增效作用的复配制剂。结果显示,绿盲蝽对韭菜籽提取物选择反应率最高,为56.04%±3.77%,显著高于葵花籽提取物和棉花叶片。当韭菜籽提取物和葵花籽提取物按照体积比3∶7复配后具有协同增效作用,且对绿盲蝽和中黑盲蝽均能表现出极强的引诱作用,选择反应率均在80%以上。结果表明,该复配引诱剂具备防治棉田盲蝽科害虫的潜在应用价值。Miridae pests including Adelphocoris suturalis and Apolygus lucorum have a wide range of hosts which are important cash crops such as cotton,jujube,and kidney bean.Due to the extensive planting of transgenic cotton,the population of Miridae pests increased significantly since the 1990s,which had a serious impact on Chinese agricultural production.Controlling these pests by chemical pesticides now faced with many disadvantages because of their pesticide resistance and strong dispersal ability.In order to obtain a new efficient and environment-friendly control method using botanical attractants for the main Miridae pests,Apolygus lucorum and Adelphocoris suturalis,in the cotton field,ethanol extracts from the seeds of Allium tuberosum and Helianthus annuus were prepared by soaking at room temperature.Three-arm olfactometer was used to compare the olfactory responses of A.lucorum to two extracts and cotton leaves.The results showed that the response rate(56.04%±3.77%)of A.lucorum to the extract of A.tuberosum was the highest,which was significantly higher than that of H.annuus and cotton leaves.When the seed extracts of A.tuberosum and H.annuus were mixed according to the volume ratio of 3∶7,they had synergistic effect and showed strong attraction to both A.lucorum and A.suturalis,with selective response rates above 80%.The results showed that the mixed attractant had intrinsic value in controlling the Miridae pests in cotton field.
