摘要
花丽细蛾是福建省茉莉的重要害虫之一,在福州室内1a发生12代,世代重叠.田间以幼虫在茉莉叶上过冬.卵产于茉莉嫩叶上,卵期2-7d.幼虫潜入叶内取食叶肉,并食成弯曲的隧道,幼虫期9-25d,老熟幼虫于叶上吐丝作茧化蛹;蛹期3-9d.成虫寿命4-11d.田间幼虫和蛹常被3种小蜂寄生致死.
Caloptilia sp. is one of the most important pest of jasmine in Fujian Province. This paper reports the results of our studies on its morphological biology conducted during 1984—1987 in Fuzhou District. Under laboratory condition it occurs 12 generations in a year and overlaps between generations. In the field the larvae overwinter on the underside of jasmine leaves. The eggs are laid on the tender leaves and hatched within 2—7 days. The larvae usually enter the tender leaves and feed on them. The larval stage is 9—25 days with an average of 13.5 days. When they become mature, the larvae spin the silk cocoons on the leaves. The pupal stage is 3—9 days with an average of 5.8 days. The adults live 4-11 days with an average of 6.9 days. The larvae and pupae are often attached by hymenopterous. These parasites usually inhibit the outbreak of the pest.
