不同食料条件下白背飞虱实验种群繁殖力及存活率模拟模型

 白背飞虱在5个生育期（苗期、分蘖期、拔节期、孕穗期、齐穗期）稻株上所产的卵，期孵化率差异不明显。若虫以取食拔节期稻株存活率最高。成虫产卵次数、日产卵量、总产卵量、各天存活率则以取食分蘖期稻株为最多。根据若、成虫存活率试验结果，建立了白背飞虱在不同水稻生育期上实验种群存活率模拟模型。

The Fecundity and Survival Simulation Modes of Experimental Population of Sogatella furcifera under Various Diet Condition

The life parameters of Sogatellafurcifera on rice at 5 growing stage (seedling, tillering, elongation,booting, heading) were studied. There were no significant differences among hatching rates of egg at 5 growing stages of rice plant. The survival rate of nymphs feeding on rice plant at elongation stage was the highest. Times of egg oviposition per female, egg number of a day per female, total egg number per female, daily survival rate of adult duration were the most when adults fed on rice plant at tillering stage. They were second in sequence when adults fed on rice plant at elongation stage. Based on experimental results of survival rate of nymph and adult, the experimental population simulation modes of survival rate of sogatellafurcifera were developed.
