摘　　要：目的分析气象因子对茶毛虫全世代生态特性和人群茶毛虫皮炎爆发的影响,为早期预防控制疾病提供科学依据。方法观察茶毛虫孵化、幼虫龄期、化蛹、羽化的全世代生态特性,调查不同季节茶毛虫皮炎爆发的病因、影响因素及患者的三间分布。结果镇江地区茶毛虫1年发生3代。茶毛虫皮炎爆发的原因为:暖冬、暖春气象有利于虫卵越冬,导致第1代虫口基数大;茶场失管、没有适时灭虫。皮炎爆发的季节差异由6～7月份的温度、湿度和雨量决定。结论茶毛虫各虫态及全世代发育速率因气象条件而异。在适宜气象条件下,幼虫3龄期后虫口累积到一定数量,即造成人群爆发皮炎。Objective To explore the effects of local climate on the ecology of tea euproctis and influence on the outbreak of dermatitis, which would provide scientific evidence for prevention and control of dermatitis causecl by tea euproctis. Methods The characteristics of whole generation of tea euproctis pseudoconspersa, including hatching, life period of larva, pupation and eclosion were observed in the field and laboratory. The etiology, influencing factors, distribution of patients with dermatitis in 1999 and 2003 were analyzed. Results There were three generations of tea euproctis in Zhenjiang annually. The main reasons of outbreak of dermatitis induced by tea euproctis were lack of control of insects and more first generation larva due to the warm winter and spring. The difference of season of outbreak of dermatitis was due to temperature, humidity, and rain volume from June to July. Conclusions The ecology and developmental speed of whole generation of tea euproctis are influenced by climate conditions, and in the appropriate condition three-stage larva may rapidly increased, and results in outbreak of dermatitis.
