| 摘 要： | 在石家庄梨园,调查了梨园梨小食心虫成虫和卵的发生规律,并进行了化学药剂防治试验。结果表明：成虫1 a出现5个高峰期,分别为4月中旬、5月底～6月初、6月底～7月上旬、7月底～8月初和8月底～9月初,以最后2个峰值较高;梨果从6月底7月初开始着卵,到梨采收时仍有卵发生。用48%乐斯本2 000～2 500倍液、4.5%高效氯氰菊酯乳剂2 000倍液、2.5%溴氰菊酯2 000～2 500倍液喷施,防治效果均较好,虫果率控制在1.31%～4.13%。并对梨小食心虫的综合防治提出了一些建议。

| Abstract: | The occurrence of adults and eggs of oriental fruit moth in pear orchard in Shijiazhuang was investigated.The pesticide control was tested.The results showed that adult had five peaks in one year including the middle ten days of April,the end of May to the early June,the end of June to the first ten days of July,the end of July to the early August,and the end of August to the early September.And the last two peaks were the highest.The eggs appeared in fruits since the end of June or the early July,and they could last for harvest.The control effects 48% chlorpyrifos EC 2 000-2 500 times liquid,4.5% beta-cypermethrin EC 2 000 times liquid,and 2.5% deltamethrin EC 2 000-2 500 times liquid were better,which could control the ratio of insect and fruit at 1.31%-4.13%.The suggestions on the integrated control of oriental fruit moth were indicated. |
