摘 要:
2003.2004年研究了上海地区为害杨树的分月扇舟蛾的生物学特性,该虫1年发生6—7代,以卵越冬,1龄、2龄、3龄、4龄、5龄幼虫头壳宽分别为0.26±0.03mm、0.37±0.06mm、0.99±0.08mm、1.78±0.19mm、2.76±0.08mm。雌雄性比1:1.25。初孵幼虫耐饥力平均为1.63±0.48d。在室外喷雾2000倍20%杀灭菊脂、4000倍30%乙酰甲胺磷、6000倍20%除虫脲、1000倍25%灭幼脲三号和6000倍1%阿维菌素7d后的校正死亡率分别在80.28%.95.61%。[著者文摘]

Abstract:
The biological characteristics of Clostera anastomosis(Linnaeus) were observed in Shanghai during 2003-2004. It occurs at 6-7 generations annually and overwinters as eggs, the width of headcapsue of the lst-5th instar larva was 0.26±0.03 mm, 0.37± 0.06 mm, 0.99±0.08 mm, 1.78±0.19 mm and 2.76±0.08 mm, respectively. The sexual ratio of female to male was 1:1.25. Average huger tolerance of 1st instar larva was 1.63±0.48 d. The corrected mortality is 80.28%-95.61% seven days after spraying with 1: 2 000 dilution of 20% Fenvalerate,1:4 000 dilution of 30% Acephate,1:6000 dilution of 20% diflubenzuron, 1:1 000 dilution of 25% Benzoy Ihenyl ureas, 1:6 000 dilution of 1% Abamectin under field test conditions.[著者文摘]
