Abstract

Plants synthesize a large number of different secondary metabolites. Secondary metabolites have been known for acting as defense against HERBIVOREs. Glucosinolates are secondary metabolite, which occur in Capparales and a few other taxa. Among the Brassicaceae, the genus Arabidopsis contains 36 different glucosinolates. In order to know whether variation in glucosinolate influences the suitability of A. thaliana for generalist HERBIVORE SPODOPTERA EXIGUA, 4 natural populations of A. thaliana was studied. Glucosinolate concentration of 4 populations analyzed using HPLC- UV.Glucosinolate were different in their quantities and abundance between all groups.Caterpillars from S. exigua were obtained from a lab culture, reared on artificial diet. In a growth chamber experiment two second instar caterpillars from S. exigua were placed on each of the plants. Laval weight of HERBIVORE was measured after 5 days. The results showed the generalist HERBIVORE S. exigua grew significantly better on the plants with lower glucosinolates. Significant correlations were negatively found between larval weight of S. exigua and glucosinolates. Larval weights of S. exigua also were affected by glucosinolate composition. Significant correlations were negatively found between larval weight of S. exigua and glucinapin, sinigrin and 4 methoxyglucobrassicin.Therefore concentration and composition of glucosinolate reduced palatability of leaf tissue to generalist HERBIVORE S. exigua.
