| 摘 要： | 咖啡天蛾Cephonodes hylas(Linnaeus)为栀子花的重要害虫。在福建一年发生3—4代,以蛹在土壤里越冬。卵单个散产于嫩叶表面,3—6天孵化。幼虫五龄,以取食嫩叶为主,历期19—47天。蛹期9—193天。成虫羽化后次日交尾,第3日开始产卵。成虫寿命2—8天。 第2—4代幼虫常感染质型多角体病毒,造成病毒病流行,是控制此虫种群的重要因素。 辛硫磷和质型多角体病毒对幼虫均有良好防治效果。结合修剪、松土可进行人工捕杀高龄幼虫和灭蛹。

| Abstract: | The humming-bird hawk moth Cephonodes hylas( Linnaeus) is a serious pest of the cape jasmine-tree(Gardenia jasminoides Ellis var. fortuniana ( Lind1. ) Hara) in Fujian Province.This paper reports the results of the studies on the biologieal characteristics and control of the pestmade from IG85 to 1986.The pest has 3-4 generations each year in Nanping, Fujian Province, Winter is passed as pupae in the soil. The eggs arc laid individually on the tender Ieaves ami to be hatched Within 3 - 6 bays. The larvae feed on the tender leaves. There, are five instars, and lasrval development lasts 39-47 days. When they become nature, the larvae descend to the ground and pupate in the soil. The adults live for 2-8 days.
The larvae are often infected with a cytoplasinic polyhedrosis virus in a way that It often reaches epizootic levels in natural populations. Thus it is an important factor in controlling the population of this pest.The effective measures to control the larvae are spraying with Phoxim, Cytoplasmic polyhedrosis virus of Cephonodes hylas. Manually collecting the fourth to fifth instar larvae and loosening the soil to kill the pupa in winter could also he effective. |
