Spodoptera frugiperda (J.E.Smith) (fall armyworm), is very serious pest in Americas and has newly be an invasive pest in Africa. Exhaustive register of S. frugiperda's plant of hosts is major to better understand the biology of this pest and develop Integrated Pest Management programmes. Impact of various plant of hosts on food consumption,host preference and several biological side,determine total protein,carbohydrate and lipid for third instar larvae of S. frugiperda were executed on laboratory. Outcome indicated that, larvae fed on leaves of maize, rice and artificial diets had the fastest larval and pupal development cycle. While those fed on pea and tomato had the longest one. In case of moth emerging from larvae fed on maize showed longest life span. But moths producing from larvae fed on leaves of tomato had the shortest life span. Obtained results revealed that, female moths produced from larvae fed on maize, rice and artificial diet laid the highest number of eggs,but female producing from larvae fed on tomato leaves produced the least number of eggs. Otherwise,the highest mean larval consumption for maize and wheat. While,larvae fed on leaves of tomato showed lowest mean consumption. Results reported that, total protein,carbohydrate and lipid were higher in the haemolymph of 3^rdinstar larvae of S. frugiperda reared on maize, wheat and rice leaves. Meanwhile, tomato and cucumber were present at a low value level. Studies showed that,maize was the preferred host for S. frugiperda,but may be also,successfully reared on another plants especially in absence of the main host.
