摘要
对埃及柽麦蛾的年生活史、习性及其天敌进行了观察。该虫在新疆阜康县 1年 3代 ,以老熟幼虫在吐丝粘着枝条形成的丝巢中化蛹 ,秋末在地面枯枝落叶层中越冬。第 1代历期 3 0～ 45d ,第2代 2 5～ 3 0d ,第 3代为越冬代。野外采集幼虫和蛹在室内盆栽多枝柽柳上进行的接种试验表明 ,埃及柽麦蛾幼虫在盆栽多枝柽柳上可以完成生长发育 ,种群增长迅速 。
Observations showed that Ornativalva heluanensis (Lepidoptera: Gelechiidae) occurred in three generations a year on saltcedar (Tamarix, Tamaricareae) at Fukang, Xinjiang. The 1st and 2nd generations took 30-45d each. The 3rd generation larvae spun silk nests and passed the winter as pupae in plant debris on the ground. Inoculation tests showed that larvae could normally developed and the population grew rapidly on the accessions of Tamarix ramosissima from the United States. Two parasitoid wasps, Elasmus sp. (Elasmidae) and Apanteles sp. (Braconidae) were emerged from the 3rd and 4th instar larvae.
