The asexual reproductive eggs and larvae were obtained when 50 commercial and bivoltine races induced by hot water. But the rate of asexual developed eggs varied markedly among these races, the range was 11. 99～88. 88 percent. About one-third races, their rates of asexual developed eggs attained 70～80 percent. The rate of asexual developed eggs about hybrid was higher than its parent.

对我国50个二化性现行品种资源进行无性繁殖发生率调查，结果表明各品种都可经诱导获得一定比例的无性繁殖发育卵和幼虫，但品种间存在较大差异，其发生率范围在11.99~88.88%之间，有1/3品种的无性繁殖发生率达到70~80%，而杂交种的无性繁殖发生率明显超过原种的水平。
