七种物质(聚乙烯醇、明胶、白乳胶、琼脂、木薯粉、米粉和淀粉一定浓度的水溶液或悬液用作松毛虫赤眼蜂Trichogramma dendrolimi拟澳洲赤眼蜂T.con fusum及广赤眼蜂T.euanescens人工体外培育的产卵增效剂以吸引这些蜂在人工卵上产卵.这七种溶液都能提高三种赤眼蜂在人工卵内的产卵量,不同的赤眼蜂对不同的增效剂有不同的产卵行为反就,我们可利用其中最有效而经济的增效剂以增强体外培育赤眼蜂的效率.
Trichogramma dendrolimi Trichogramma dendrolimi Trichogramma T.con fusum and broad-red eye (polygryl alcohol, gelatin, white latex, agar, tapioca, rice noodles and starch at a certain concentration of aqueous solution or suspension) The beetles T.euanescens were cultured in vitro by artificial spawning synergists to attract the bees to lay eggs on the artificial eggs.These seven solutions can increase the amount of eggs laid in the artificial eggs of three Trichogramma species, There are different spawning behaviors for different synergists. One of the most effective and economical synergists can be used to enhance the efficiency of trichogramma cultivation in vitro.
