摘要
用红外光、紫外光照射蝗虫卵,观察其对蝗虫卵孵化率等的影响。结果表明:红外、紫外育种和杀虫具有可行性。25 W的红外光照射无预先培养的虫卵20 min左右可以显著提高其孵化率,达95%以上,降低其最快孵化时间(降低4 d)和加快其总体孵化速度(提前3 d)。25 W的紫外光照射无预先培养的虫卵40 min以上,杀虫率可达87%以上,并且可以延缓其最快孵化时间(可延缓6 d)。
The effect of infrared and ultraviolet irradiation on the eggs of locust was studied. The results showed that using infrared and ultraviolet to breed and kill was feasible. It could improve the hatching rate significantly using 25 W infrared on the eggs for 20 min,the rate reached over 95% ,decrease the fast hatching time（decreasing 4 days） and accelerate the general hatching velocity（about 3 days）, When irradiating over 40 min, killing rate could over 87% ,and could also the fast hatching time（6 days）.
