采用室内试验结合野外观察的方法,研究新银合欢软蜡蚧(Coccus sp.)在昆明市区和东川区两地的年生活史及生活习性。结果表明:新银合欢软蜡蚧在昆明市区1 a发生4代,在东川区1 a发生4～5代,世代重叠,没有明显越冬现象,越冬虫态以1龄、2龄若虫为主。雌成虫将卵产在腹膜下,卵直接在腹膜下孵化。若虫经2龄发育为成虫。1龄若虫具爬行能力,2龄若虫固定不动,雌成虫营孤雌生殖,寿命7～25 d。
Through the test in lab in Kunming and obseration in Dongchuan,the life history and living habits of this pest in these two areas were studied.The results showed that Coccus sp.had 4 generations annually in the lab and had 4-5 generations in Dongchuan,overlapping generations and not obvious over-wintering generation.The main instars were 1 and 2 instar nymphae in winter.The female adult spawned eggs in the peritoneum.Nymph developed into adults by 2 ages,1 instar nymphae was able to crawl,2 instar nymphae fixed.Female adult was parthenogenesis and its lifetime was 7-25 days.
