| 摘 要： | 樗蚕在荆州市1年发生2代,以蛹越冬.第一代幼虫期6月上旬～7月中旬,危害盛期为6月下旬;第二代幼虫期8月下旬～10月上旬,危害盛期为9月中旬.人工剪除越冬茧蛹,成虫羽化盛期使用黑光灯和杀虫灯诱杀,可降低虫口基数.在低虫口密度时,采取生物制剂防治和保护利用天敌的措施,可以有效控制樗蚕的发生和危害;在高虫口密度时,使用高效、低毒、低残留的无公害药剂喷雾防治,可以迅速压低虫口密度.

| Abstract: | Abstracts:Philosamia Cynthia has two generations every year in Jingzhou and overwinters as pupae;The larvae period of its first generation is from early June to middle July and the harmful period is in late June;The larvae period of its second generation is from late August to early October and the harmful period is in middle September.Cutting its overwintering chrysalis artificially and trapping its adult by the black light lamp or the insecticidal lamp during its emergence peak period can reduce its population number.At the low density of Philosamia Cynthia,taking measures to protect and utilize the natural enemies and using the biological agents use can effectively control the occurrence and damage of Philosamia Cynthia;At the high density of Philosamia Cynthia,using pollution-free pesticides of high efficiency,low toxicity and low residue can lower the population density quickly. |
