Abstract:

Chillies (Capsicum annuum) are an important commercial and export-oriented crop in India. Whitefly, Bemisia tabaci is a serious pest on chillies by destabilizing the plants through desapping plant juice and also transmitting chilli leaf curl disease (ChiLCD). Varietal resistance is the most economic, least complicated and environmental friendly approach for the control of insect pest damage. Fifteen accessions of Capsicum were screened against whitefly, under green house condition for categorization of the mechanism(s) of resistance. Accessions CA9, CA28, CA29, ACC 05, ACC 16, ACC18 and ACC 29 were found to be less preferred for adult settlement, whereas accessions CA17, CA30, CA187, CA189, CA247 and ACC08 were the most preferred one. In resistant accessions of chillies accumulative reduction in pest population was noticed by reduced rate of reproduction and increased developmental period. The number of eggs laid and the percentage of nymphal and adult emergence were low on resistant accessions viz., CA9, CA28, CA29, ACC 05, ACC 16, ACC18 and ACC 29. In population build-up study, significantly lower numbers of progeny were observed on accessions CA9, CA28 and ACC05. Conversely, the number of progeny produced by F2 was significantly greater on ACC 08. Additional experiment indicated that tolerance category of resistance was present in the accessions viz., K2, CA 247, CA 189 and CA 187 for B. tabaci feeding. The accessions CA 9, CA28 and ACC 05 have displayed strong antixenotic and antibiotic effect against whitefly, Bemisia tabaci.
