Abstract

Data suggest that the flower thrips, F. insularis, could reduce the yield of pigeon pea, Cajanus cajan, cv. UW 17. Yield (pod-set) per plant differed by 47·25 per cent in thrips-free plants as compared with thrips-infested plants. Evidence also suggested the likely importance of cross-pollinators with a possible contribution of 42 per cent towards the final yield per plant.
