摘　　要：利用平腹小蜂Ａｎａｓｔａｔｕｓｓｐ．防治荔枝蝽的若干技术问题进行研究与探讨．结果表明，平腹小蜂在田间以成虫和老熟幼虫越冬．平腹小蜂成虫的抗寒性比较差，如３℃条件下待续２～４ｄ就出现部分虫体被冻死，但仍有一定的抗寒能力，在３℃条件下持续１０ｄ以后，还有１／５的被测试虫体未被冻死．成虫羽化的最适温度为３０～３２℃．荔枝蝽产卵始盛期为当年第１次散放平腹小蜂的最适时期，于散放平腹小蜂前１０ｄ喷第１次农药，再行放蜂，又于放蜂后５０ｄ喷第２次农药，还可防治其它病虫害，是最佳的综合防治方案．Several technological problems of applying Anastatus sp.to control Tessaratoma papillosa were studied and the results were presented in this paper. A.sp. overwintered with adult and mature larva in fields. Adult of A.sp. possessed low cold tolerance, so that some tested adults died at 3℃ for 2-4 days, but still onefifth of them survived in 10 days later. The optimal temperature of adult emergence was 30-32℃. The optimal option of　the first time to release A.sp. in a year could be in the stage when T.papillosa began to oviposit in a large quantity. The best strategy of intergrated management for T.papillosa was to release A.sp. in 10 days after the first spraying of pesticide and 50 days before the second spraying.
