【摘要】 昆虫病原线虫制剂产业化需要有效的贮存方法。本试验利用国产硅藻土和高分子凝胶，比较硅藻土和凝胶不同比例、不同温度及添加防霉剂，对线虫存活率、霉菌控制和线虫毒力的影响。线虫在１０℃下２４周后存活率仍达９０．５％，线虫对大蜡螟幼虫的感染率仅下降１９．５％。 ２３℃下贮存８周时，存活率高于９３％，但１６周后几乎全部死亡；对测定昆虫的感染率８周后下降了２６．８％。加人的食品抗霉剂对线虫存活率和感染率无明显影响，但防霉效果仅维持２周。结果表明，利用国产硅藻土可贮存Ｓｔｅｉｎｅｒｎｅｍａ　ｃａｒｐｏｃａｐｓａｅ线虫。。更多还原

【Abstract】 Survival and infectivity of the dauer juveniles of Steinernema carpocapsae A24 were determined to evaluate the suitability of a domestic attapulgite clay for nematode formulation. 50 g (80 × 106 dauer juveniles) of S. carpocapsae were mixed with 60 g of domestic attapulgite clay, and respectively Placed in 10℃ and 23℃, 75% RH growth cabinets. 90.5 % of freshly harvested dauer juveniles survived after 24 weeks at 10℃ and their infectivity to Galleria mellonella larvae dropped slightly. Survival of the dauer juveniles at 23℃ decreased to 93% in the find 8 weeks and then dropped sharply to about 50% on the 12th and 0 % on the 16 th. The infectivity of the dauer juveniles at 23℃ was 19.5 % less at week 4 and 26.8 % at week 8.更多还原
