摘　　要：对不同气候类型、繁养方式繁养的胭脂虫的胭脂红酸（CA）含量进行测定，结果表明：不同气候类型的胭脂红酸质量分数为14．56％-26．29％，平均为19．78％；春虫、夏虫和秋虫的胭脂红酸质量分数分别为19．79％、21．03％和18．51％。同一气候类型、自然条件下的胭脂红酸含量为17．71％～19．79％，平均18．77％；遮阴棚中的为20．84％-23．96％，平均22．06％；塑料大棚中的为18．74％～26．29％，平均22．24％；胭脂红酸平均含量（B试验点）分别为春虫23．35％，夏虫20．45％，秋虫19．27％。收虫季节、试验点的胭脂红酸含量无显著性差异，繁养方式和胭脂虫级别的胭脂红酸含量呈极显著性差异。依此提出在南亚热带气候区应以塑料大棚和遮阴棚繁养胭脂虫，而中亚热带和北亚热带气候区以塑料大棚繁养为宜。Carminic acid （CA） of cochineal insects （Dactylopius coccus Costa） which were bred in different climate conditions and different bred methods was determined. Results showed that the CA contents of cochineal insects bred in different climate conditions were 14.56%--26.29% with average 19.78%. Therein, the CA contents of cochineal insects harvested in spring, summer and autumn were 19.79% , 21.03% and 18.51% respectively. The CA contents of cochineal in- sects bred in the same climate conditions were 17.71%--19.79% with average 18.77% in nature condition, 20.84%- 23.96% with average 22.06% in shade canopy, 18.74% --26.29% with average 22.24% in greenhouse. Therefore, the CA contents of cochineal insects harvested in spring, summer and autumn were 23.35% , 20.45% and 19.27% from site B. There was no significant difference in CA of cochineal insects derived from different bred areas and harvest seasons. Nevertheless, there was high significant difference in CA of cochineal insects derived from different bred methods and cochineal insects＇ classes. The results indicated that it was suitable to breed cochineal insects under the plastic house and the shade canopy in south subtropical, but under the plastic house in middle subtropical and north subtropical.
