对中华草蛉卵喷卵和挂放卵卡试验表明,在5种不同卵粘着剂中,0.125％琼脂溶液效果最好,蛉卵悬浮均匀,粘着率为96.83％,浸卵2—3小时后,孵化率为80.77—92％;发育后期的蛉卵,在溶液中承受1—2.5kg/cm~2压力15分钟后,经高速旋转喷出,孵化率为65.06—78.21％,较对照明显提高;田间喷卵,孵化率为51.06—60％,与对照无明显差异。用发育后期的卵直接挂放田间,卵卡上先孵幼虫残杀卵率为6.45％,卵粒孵化率为72.26％。较用工农—16型手摇喷雾器喷卵的孵化率(51.06—60％)提高了12％。
The results showed that 0.125% agar solution had the best effect among the five kinds of different egg-sticking agents, and the oyster suspension was uniform, with an adhesion rate of 96.83%. After soaking eggs for 2-3 hours , The hatching rate was 80.77-92%. In the late developmental stage, the ovipositor was subjected to a pressure of 1-2.5kg / cm ~ 2 in solution for 15 minutes. After being spun at a high speed, the hatching rate was 65.06-78.21%, which was significantly higher than that of the control ; Spraying in the field, hatching rate was 51.06-60%, no significant difference with the control. The newly hatched eggs were placed in the field directly at the late stage of development. The larvae egg hatch rate was 6.45% and the egg hatching rate was 72.26%. The hatching rate (51.06-60%) was 12% higher than that of spraying with worker-peasant -16 hand sprayer.
