在美国白蛾第1代幼虫期喷施了小分子诱导制剂,喷后3d美国白蛾幼虫活动迟缓率达90%,不再取食危害叶片,不能正常完成化蛹,幼虫肠道蛋白凝结死亡。试验为防治美国白蛾提供了有效、安全、无公害的防治药剂,改变了以往重复喷药效果差的局面。小分子诱导制剂防治美国白蛾每代喷药一次即可,喷施次数少、用量小、经济、安全、无毒,属于生物防治措施。
Small-molecule-induced preparations were sprayed on the first generation larvae of C. medinalis. After 3d, the larvae of Laodelphax striatellus larvae delayed their activity to 90%, no longer fed on the leaves and could not complete pupation. The larvae died of intestinal protein condensation . Test for the prevention and control of American white moth provides an effective, safe, pollution-free control agents, changing the previous repeated spraying ineffective situation. The small molecule inducing preparation can prevent and cure the American white moth once a time, spraying less times, less dosage, economical, safe and non-toxic, which belongs to biological control measures.
