栗瘿蜂在北京地区一年发生一代。无雄蜂,营孤雌生殖。以初龄幼虫在栗芽组织内越冬,翌年5月下旬幼虫老熟在虫瘿里化蛹,6月中、下旬羽化,脱孔出蜂,产卵于栗芽内。卵于7月中旬孵化,初孵幼虫先在栗芽组织表面危害,然后形成小虫室越冬。室内药效测定表明,10%六六六乳剂200倍液、50%杀螟松乳剂1000倍液、50%乐果乳剂1000倍液,对刚脱孔和正在咬孔的成虫触杀效果都很好。田间栗树喷药试验结果表明,成虫羽化95%以上时,喷布10%六六六乳剂或超低量油剂,效果良好。冬季剪枝,保留结果母枝和有用发育枝,防虫效果明显。保护及利用自然天敌长尾小蜂是防治栗瘿蜂值得注意的途径。
Chestnut bee bees occur in Beijing one generation a year. No drone, camp parthenogenesis. The first instar larvae wintering in the chestnut bud tissue, the larvae mature in late May the following year pupae insects, emergence in mid-June, late, take off the hole bees, spawning in the chestnut bud. Eggs hatch in mid-July, first-hatched larvae first chestnut bud tissue surface damage, and then form a bug room overwintering. Indoor efficacy tests showed that 10% BHC emulsion 200 times, 50% fenitrothion emulsion 1000 times, 50% dimethoate emulsion 1000 times, just off the hole and are biting adult worm kill effect is very good . Field chestnut spraying test results show that adult emergence of more than 95%, spray 10% BHC emulsion or ultra-low oil agent, the effect is good. Winter pruning, retain the results of the mother branch and the useful development of branches, pest control effect is obvious. Protection and use of natural enemies Polar beetle is a noteworthy way to control chestnut bee.
