Abstract

Study on population of pod borers (Helicoverpa spp.) on expectation and spring planted chickpeas carried out for two years in Maragheh (region) and Kermanshah (region). Eight promising varieties of Kabuli and Desi types planted in RCBD (split plot) with three replications. Planting dates attvibutedt main-plots and varieties to sub-plots. The results showed that in Maragheh region because of the unconformity of pest biology and plant phenology, expectation planting scaped from the pest damage. Mean number of larvae and infestation of pod borers on spring planted plots was higher than expectation planted plots. Analysis of variance results for population of pod borers and infestation rate indicated that there is a significant difference between expectation and spring plantings. On the contrary in Kermanshah, population of density pod borers in expectation planting was more than spring planting but the yield of expectation planting was than spring planting. Therefore the utilization of resistant varieties in winter planting will be affective in sumage reduction.
