摘要
本文报道繁殖赤眼蜂的人工寄主卵液关键物质浓缩干燥剂的研制。４批试验的结果证明，在－５℃下保存４４～５５个月的柞蚕蛹匀浆冷冻干燥剂，稀释成人工卵液后制成的人工卵卡，繁殖赤眼蜂，卵粒寄生率可达９１．４９％～９８．８６％；蜂蛹羽化率达７６．３２％～８４．４９％；雌蜂能育率为７０％～８０％；繁殖倍数达９．６２～１１．７４倍；质量与新鲜蛹匀浆无明显差异。该制品体积小，方便贮藏和远距离运输，保存期长，一次制备可供４年应用；繁殖工作可不受季节限制。
Since 1985, 4 batches of Antheraea pupal holotissues, which were concent reated and dried with antiseptic and protective material were stored in 5℃ in our laboratory. After storing 44～55 months, the dried holotissue was made int o artificial eggs and compared with artificial eggs made of fresh holotissue. Th e result showed that 91.49%～98.86% of the artificial eggs were parasitized, f rom which 76.32%～84 49% emerged adults. The fecundity was 70%～80% and th e propagation coefficient was 9.62～11.74 for the stored and fresh holotissues, respectively. This method is very convenient for storing and transporting of a rtificial diet due to its smaller size and availability at any season for indust rial production of Trichogramma spp..
