柑桔爆皮虫是为害柑桔的一种毁灭性害虫,浙江衢县普遍发生,历年来为害惨重,个別生产队已有半数以上的桔树忍痛砍伐,多年經营毁于一旦,給柑桔生产带来巨大損失。爆皮虫的发生世代很不整齐,以幼虫在木質部或韌皮部中越冬,翌年3月上旬开始化蛹,3月底、4月初为化蛹盛期,3月底开始羽化为成虫,4月底为羽化高峯,成虫出洞与溫湿度关系密切,5月初开始出洞,5月15—21日为出洞高峯,5月下旬开始产卵,估計6月5日至7月1日为产卵盛期,卵期約10—21天,6月中旬开始孵化为幼虫,6 月下旬至7月中旬为孵化盛期,幼虫孵化后即侵入树皮为害,造成流膠、爆皮等症狀,最后树皮枯死剝落,整株桔树死亡。防治爆皮虫的藥剂以1:1火油加25％223乳剂混合液为佳。在10、11月防治越冬前幼虫,在4月底5月初防治出洞前成虫,效果均良好。在7、8月份对剛孵化的幼虫应用1:1或2:1火油加223乳剂,及5％223油剂防治效果也在93％以上。此外,掌握成虫产卵习性,在幼虫孵化前,产卵盛期后进行一次刷卵工作,將已枯死的桔树,在4月份前挖起燒毁,平时加强桔园田间管理,对防治爆皮虫都有一定作用。总之,只有全面的貫彻綜合防治措施,才能彻底的消灭爆皮虫的为害。
Citrus detritivore is a devastating pest that affects citrus. Quzhou County in Zhejiang Province is a common occurrence and has been devastatingly affected over the years. More than half of the individual production teams have reluctantly felled the trees and destroyed many years of operation. Citrus Production has brought huge losses. The occurrence of nematode insects from generation to generation is not neat, larvae wintering in the xylem or phloem, pupation began in early March the following year, the end of March, early April pupation peak, end of March began to emerge into adults, the end of April for the emergence of peak , Adult wormhole and temperature and humidity are closely related to the beginning of early May hole, May 15-21 for the hole to the peak, spawning in late May, it is estimated June 5 to July 1 for the spawning peak, Egg stage of about 10-21 days, beginning in mid-June hatching larvae, late June to mid July incubation period, the larvae hatch after invasion of the bark damage, resulting in plastic flow, blasting and other symptoms, the last bark dead Peel off, the whole plant died of orange trees. Prevention and control of explosives pesticides to 1: 1 oil plus 25% 223 emulsion mixture is better. Prevention and treatment of pre-winter larvae in October and November and prevention and treatment of pre-cave adults at the end of April and early May were all good. The application of 1: 1 or 2: 1 fire oil plus 223 emulsion to newly hatched larvae in July and August, and the control efficacy of 5% of the 223 oils are above 93%. In addition, to master adult spawning habits, larvae hatch before the spawning peak after a brush work, the dead orange trees, burned before April burned, usually to strengthen the orange field management, the prevention and treatment of explosion Leather worms have a role. In short, only a comprehensive implementation of comprehensive prevention and control measures can completely eliminate the damage of the insect.
