不同马铃薯品种对桃蚜发育和繁殖的影响
Effects of different potato cultivars on the development and reproduction of green peach aphid,Myzus per-sicae
摘要
Abstract
To explore the effects of potato cultivars on the life table parameters of green peach aphid(Myzus persi-cae),and to provide a basis for the evaluation of aphid-resistance of potato cultivars and the population prediction and integrated management of M.persicae,we examined the growth and development parameters of M.persicae on three potato cultivars(Holland 15,Longshu 10,and Longshu 14)in laboratory.We analyzed the effects of potato cultivars on the growth and development,survival rate,fecundity,life expectancy(exj),reproductive value(vxj),and population parameters of M.persicae using the age-stage,two-sex life table.The results showed that M.persicae exhibited a longer developmental duration,shorter longevity and life expectancy(exj),and lower fecundity and re-productive value(vxj)when reared on the Holland 15 than on the Longshu 14.Moreover,net reproduction rate(R0),intrinsic rate of increase(r),and finite rate of increase(λ)of M.persicae was lower when reared on the Holland 15 than on the Longshu 10 and Longshu 14,whereas mean generation time(T)and population doubling time(Dt)was longer on the Holland 15 than on the Longshu 10 and Longshu 14.Our results indicate that M.persi-cae has different adaptability to different potato cultivars,and that the resistance of Holland 15 against M.persicae is significantly higher than that of Longshu 10 and Longshu 14.关键词
