Influence of Host Plants on The Growth and Development of Cheilomenes Sexmaculata (Fabricius) (Coleoptera:Coccinellidae) Prey on Aphis Craccivora Koch
Abstract: Allelochemicals and physical barriers such as wax of leaf surfaces, trichomes, cell wall thickness and lignifications of host plants play important role in unsuitability of prey to predatory lady beetles. Four economically important host plants of family Fabaceae (Phaseolus sinensis, Lablab purpureus, Vigna radiata and Vigna mungo) infested by Aphis craccivora (Hemiptera Aphididae) were selected for experiment to observe the growth pattern of one of the most potent predator of aphids, Cheilomenes sexmaculata (Fabr. ) (Coleoptera Coccinellidae). The significant variation was observed in the length and width of grubs of each instar stage of predator when preyed on A. craccivora on these host plants. The maximum growth of each instars were observed on P. sinensis followed by L. purpureus, V. radiata and V. mungo. The highest length (7.290.15mm) and (1.320.06mm) in width of 4th instar larvae was recorded on P. sinensis than other host plants at 19.450.55C and 60.851.015 % RH. This variation is observed significant by ANOVA test for length (F1=28922.7, F2=18.6, P
