摘　　要：栗剪枝象鼻虫在福建一年1代，以老熟幼虫在土中筑土室越冬，5月上、中旬化蛹，6月上旬成虫羽化出土，7月中旬至8月中旬为危害盛期，在成虫羽化始盛期、高峰期、末期各喷洒一次50％辛硫磷或80％敌敌畏或25％亚胺硫磷1000倍液，均有良好效果．Cyllerhynchites ursulus (Reolofs) Reproduces only one generation each year and overwinters as larvae in soil. The pest pupates in early and middle March The adult begins to appear in early June and bores does harm to the branch critically from middle July to middle August. The effective measures to control the adult are spraying with 50% Phoxim. 80%DDVP or 25% Phosmet three times while it emerges mostly.
