摘      要：Fall armyworm(FAW),Spodoptera frugiperda(***),is a majorpolyphagous pest with the potential to seriously damage various crops.A better under-standing of FAW s performance on different hosts may help to predict which plants willbe attacked when the preferred host is absent,and facilitate the development of effectivepest management *** compared the larval performance of FAW fed on maizewith that of FAW fed on potato and tobacco,which are important crops in China,usingan age-stage two-sex life table and adult female oviposition preference *** experiments with potato,tobacco,or maize as the host,FAW reared on maize exhib-ited the strongest performance with shorter developmental time in thc larval stage,longerlongevity,and a higher reproductive rate in *** oviposited on maize in pref-erence to potato or *** with larvae fed on maize,those fed on potato andtobacco exhibited significantly lower survival,with only 31.61%and 8.13%developing tothe adult stage,*** life table parameters,including the mean generationtime(T),net reproductive rate(R^(0)),finite rate of increase(λ),and intrinsic rate of nat-ural increase(r)were negatively affected in FAW fed on potato and *** resultssupport the preference-performance hypothesis,that is,that herbivore females maximizefitness by choosing host plants associated with strong larval *** lar-vae and adults performed poorly on potato and tobacco,their offspring will be capable ofcstablishing populations on them,posing a potential threat to these crops in China.
