以棉蚜Aphis gossypii Glover饲养日本通草蛉Chrysoperla nippoensis(Okamoto)作为对照,用一种半固体人工饲料连续饲养10代日本通草蛉,对日本通草蛉各生长阶段的生长和发育指标进行观测。结果显示,用人工饲料饲养的日本通草蛉的幼虫历期为13～15d,蛹期为8d,较对照组的7d和6d分别延长6～8d和2d;用棉蚜饲养的对照组日本通草蛉幼虫累计存活率为94%,成虫获得率为87%,而人工饲料饲养连续10代的幼虫累计存活率为81%～89%,成虫获得率69%～79%。取食人工饲料的日本通草蛉成虫,在产卵前期、产卵量、产卵期及寿命方面与对照组存在显著的差异,人工饲料组草蛉的产卵前期为5.07～5.22d,而对照组草蛉的产卵前期为4.12d,人工饲料组草蛉的产卵量为190～390粒,对照组的单雌产卵量为667.2粒,人工饲料组草蛉的寿命为36～38d,对照组成虫寿命52d。以上结果表明,这种半固体人工饲料可以满足日本通草蛉幼虫生长发育基本需要,可用于日本通草蛉的室内继代饲养,但需要进一步优化配方。
Aphis gossypii Glover was used to feed Chrysoperla nippoensis (Okamoto) as a control, and the growth and development of each stage of T. japonicus were observed with a semi-solid artificial diet for 10 generations. The results showed that the larvae of Thunnuscaus przewalskii fed with artificial diet had a larval duration of 13-15 days and a pupal stage of 8 days, which were prolonged by 6-8 days and 2 days respectively compared with the control group at 7d and 6d respectively. In the control group, The cumulative survival rate of larvae was 94% and the adult’s acquisition rate was 87%. The cumulative survival rate of larvae fed on artificial diet for 10 generations was 81% -89% and the adult’s acquisition rate was 69% -79%. There was a significant difference between control group and pre-oviposition period, spawning time, oviposition period and life span of artificial feeding group, while that of artificial feeding group was 5.07-5.22d, while that of control The pre-oviposition stage was 4.12 days for the group of grass 蛉, 190-390 for the grass-fed group and 667.2 for the control group, while that of the artificial feed group was 36-38 days. Control component life 52d. The above results show that this semi-solid artificial feed can meet the basic needs of Japanese thistle larvae growth and development can be used for indoor passaging of Japanese thistle, but further optimization of formulations.
