not in Young Studies on population dynamics of field bean revealed that, during the study period 22 species of insect pests were recorded on field bean. Population build up of pod borers noticed from May II fortnight to February I fortnight with peak during the II fortnight of November. The pod borers population exhibited significant negative correlation with minimum temperature and non-significant negative correlation with maximum temperature and relative humidity. However, it was nonsignificant positive correlation with total rainfall. Among sucking pests Aphis craccivora Koch, leaf hoppers, thrips, Riptortus pedestris F., Riptortus strennus Horvarth, Coptosoma cribraria F, Anoplocnemis phasiana F. and Nezara viridula L. were more predominant. Defoliators like Spilactia obliqua Walker and grass hoppers were also observed but in less numbers. The natural enemies recorded included Campoletis chlorideae Uchida, Bracon sp. nr. green, Herpector costalis (Str.), Cryptopeltis tenuis (Mirid! ), ladybird beetles, mirids, syrphids and carabid predators.
