Abstract
th week of February was found to be very favourable for aphids in wheat fields in the study area. The highest and lowest populations of coccinellid predators (all species) were recorded on TW0135 and 99T007 cultivars, respectively. The highest population of coccinellid predators was recorded during the 3 rd week of February. We observed a significant synchronization between aphids and coccinellids populations. It is concluded from the study that as INQLAB-91 is resistant to the attack of aphid’s population, this cultivar should be promoted in the areas of high aphid infestation. The populations of coccinellids follow the aphid’s population and coccinellids can be important biological control agents of aphids and can be imported tool for IPM programme in the study area.
