Abstract：In recent years beet armyworm Spodoptera exigua( Hübner) has seriously infested crops of cabbage，cowpea，
scallion and asparagus in the Shanghai area． The impact of host plant selection on development of S． exigua were
investigated in the laboratory at (27 ± 1)℃，RH 70% ± 5% ，and photoperiod of L∶ D = 14 ∶ 10． The results revealed
significant differences between host plants in duration of larval development，larval survival rate，pupal weight，adult
longevity，adult eclosion，the intrinsic rate of increase and net reproduction rate． The mean number of eggs laid by females
reared on cabbage was significantly greater than for those reared on scallion or asparagus． Similarly，pupal weight，adult
eclosion，the intrinsic rate of increase，and net reproduction rate were significantly higher on cabbage than on scallion and
asparagus． The results suggest that cabbage provides better food quality for beet armyworm than other host plants．
