The rate of infestation and its distribution can be in fluenced by feeding through direct and indirect effects on their life cycles. Thus, this study aimed to examine the biological character-istics, food preference and leaf consumption of C.includens on soybean (BRS 284), cotton (FMT 701), sun flower (BRS 323) and common morning glory leaves (Ipomoea sp.) as possible host plants. The experiments were conducted with specimens obtained from mass rearing in the laboratory.C. includens larval and larval-adult stages were shorter in sun flower and longer in cotton. Also, larval preference was greater for sun flower and lower for cotton leaves. Soybean leaves were consumed the least in contrast to sun flower and common morning glory leaves, which were consumed the most. These results suggest that soybean, sun fl ower or common morning glory leaves were favourable hosts for C. includens development, whereas cotton leaves are less nutritionally adequate for insect development. In addition, sun flower leaves reduce C. includens development time and promotes a survival rate greater than 95%, and the leaves are more attractive to larvae when compared with the other tested hosts. This indicates sun flower is the most favourable host among the tested plants for C. includens. aSoja1 aBUENO, A. de F.1 aSILVA, D. M. da1 aSTECCA, C. dos S.1 aPASINI, A.1 aOLIVEIRA, M. C.
