摘　　要：在湿度80%、L//D=12h//12h的条件下,分别设置7、16、18℃储存巴氏新小绥螨6、12、18 d处理,另设26℃饲养巴氏新小绥螨0、6、12、18 d为对照,测定不同温度与时间的储存处理对巴氏新小绥螨存活率与生殖力的影响。在18℃下储存6 d时,巴氏新小绥螨的存活率最高,为110.50%;在储存天数均为18 d时,16、7℃下存活率分别为91.00%和90.50%,显著高于18℃下的存活率。在16、18℃下储存18 d后,单雌7 d总产卵量较高。综合调查数据得出:巴氏新小绥螨短期储存可在18℃下放置不超过6 d,在7℃和16℃下储存均可延长产品货架期至18 d,在7℃下储存18 d可用于大田释放,在16℃下储存18 d可用作保种。Under the conditions of 80%humidity of 80%and L//D=12h//12h,we set up treatments of storing Neoseiulus barkeri at 7,16,18,and 26℃(control)for 6,12,and 18 days to study the effects of storage temperature and time on the survival and fecundity of N.barkeri.When stored at 18℃for 6 days,the survival rate of N.barkeri was the highest at 110.50%.After 18 days of storage,the survival rates at 16℃and 7℃were 91%and 90.5%,respectively,significantly higher than those at 18℃.After storage at 16℃and 18℃for 18 days,the total fecundity per female for 7 days was significantly higher than that of the control.Comprehensive survey data showed that short-term storage of N.barkeri can be stored at 18°C for no more than 6 days,and the shelf life of the product can be extended to 18 days at 7℃and 16℃.Storage at 7℃for 18 days can be used for field release,and storage at 16℃for 18 days can be used for breed conservation.
