Effects of Rearing Density and Sex Ratio of Adult Arma chinensis (Hemiptera: Pentatomidae)on Their Survival, Fecundity and Offspring's Suitability
摘要
Abstract
Arma chinensis is one of the most important predatory natural enemies predating on more than 40 important pests in China.To develop a mass-rearing protocol ofA.chinensis,we tested the effects of rearing density (female/male were 4F/2M,2F/1M,3F/3M,2F/2M and 1F/1M) and sex ratio (female/male were 4F/2M,3F/3M,2F/4M,6F,and 6M) of adult A.chinensis on their survival,fecundity,trophic eggs ratio,egg hatchability,and fitness of offspring in the laboratory.The results showed that rearing density and sex ratio of A.chinensis significantly affected the survival,fecundity,trophic egg ratio and egg hatchability,but had no effects on the development and sex ratio of offspring.A.chinensis in 2F/2M treatment had high survival rate (65％) and lowest trophic egg ratio (12.68％),with fecundity of 105.5 eggs/female that was not significantly different from that of the 1 F/1M treatment showing the highest fecundity.The hatchability of eggs in the 4F/2M treatment (88.05％) is the highest,but not significantly different than that of the 2F/2M treatment (81.57％).Adult ofA.chinensis in 2F/2M had the highest fitness index (441.14),while those in 3F/3M had the lowest (35.21).In conclusion,A.chinensis performed the best when reared at two male and two female per plastic cup of 10 cm high and 7 cm in diameter.The results suggest that appropriate rearing density and sex ratio can greatly promote fecundity ofA.chinensis.关键词
