Protein and sugar were two important nutritional factors in the process of growth and development to B.dorsalis.The fecundity and life table of experimental population of B.dorsalis under different nutrition condition were studied.to provide a theoretical guidance to understand the mechanism of protein bait.The results of fecundity showed that the amount of eggs was significantly different among different nutrion conditions(p0.05).The fecundity was larger when the ratio was 1 to 3,in which the total eggs was 1.61 mL.The results of life table showed that the survival rate and life expectancy of the experimental population fed protein bait was better than that fed fugar before 22-day old,but the mortality rate was increased rapidly after laying egg for 15 days,in which the number of death was 76 from 25 to 28-day old.On the contrary,although the death number of population fed sugar was greater in prior period,the whole death process was more gentle.The survival curves of two corhorts were typical convex,and both showed relatively flat before 22-day old,then decreased rapidly from 22 to 40 days old,and became to slowly after 40 days,and the longest survival time of two populations were 49 d and 52 d.
