木橑尺蠖(Culcula panterinaria Bremer et Grey),又名小大头虫、黄楝木尺蛾。在豫西地区主要危害刺槐、栎类、核桃、五角峰、杨树、柳树等多种树木和作物。1a发生1代,以蛹在土中越冬;越冬蛹5月下旬开始羽化,7月上旬为羽化高峰期;卵产在刺槐1年生的枝稍阴面或草丛中;幼虫7月上旬开始孵化,7月下旬为盛期。老熟幼虫于8月中旬开始化蛹,老熟幼虫下树后在疏松的土壤中结茧,9月上旬为化蛹盛期,10月下旬为末期。7月下旬至8月上旬为幼虫防治最佳时期,建议用阿维灭幼脲悬浮剂进行防治,效果较好,对环境无污染。
Culcula panterinaria Bremer et Gray, also known as the small buteo, neem wood moths.
