摘　　要：为探寻扶桑绵粉蚧（Phenacoccus solenopsis Tinsley）对高温干旱的适应性,在37,39,41,43,45℃,相对湿度20％,30％,50％,70％,90％的条件下对扶桑绵粉蚧雌成虫进行了处理试验,并对扶桑绵粉蚧存活率及发育情况进行了统计.结果表明,扶桑绵粉蚧存活率随温度升高而降低,37~43℃条件下,扶桑绵粉蚧存活率与处理时间长短无关,在45℃条件下,处理时间越长扶桑绵粉蚧存活率越低；不同空气相对湿度条件下扶桑绵粉蚧存活率差异不显著（P ＞0．05）,但空气相对湿度对扶桑绵粉蚧发育历期存在明显影响,即相对湿度高发育历期短,相对湿度低发育历期长；根据试验结果来看,扶桑绵粉蚧在新疆高温、干旱的环境条件下是可以存活的,并可以在野外完成各虫态的正常生长发育,顺利越夏.In order to explore the adaptability of Phenacoccus solenopsis Tinsley in fields in Xinjiang,sur-vival rates and developmental conditions of its female adult were observed in this paper at different high temperatures （37 ℃,39 ℃,41 ℃,43 ℃ and 45 ℃）and different relative humidities levels （20%,30%, 50%,70% and 90%）.The results showed that survival rate of Phenacoccus solenopsis Tinsley decreased with temperature increase;Under the conditions of high temperature 37 -43 ℃,the survival rate of Phe-nacoccus solenopsis Tinsley had nothing to do with long or short processing time.Under the conditions of 45 ℃,the longer the processing time was,the shorter the survival rate of Phenacoccus solenopsis Tinsley was.Ambient humidity had no influence on its survival rate but a great influence on its developmental peri-od-the higher the humidity was,the shorter the developmental period became.According to the outdoor test results,Phenacoccus solenopsis Tinsley in Xinjiang can survive with the high temperature and arid environ-ment and complete its life cycle in fields in summer.
