Abstract:

The present investigation on Effect of intercropping on seasonal incidence of maize aphid, Rhopalosiphum maidis was carried out at Instructional farm and Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur. Maize variety Pratap maize-5 was sown with different intercrops viz., green gram, black gram, cowpea and soyabean in kharif, 2017. The experiment was laid out in plots size 3.0 m x 5.0 m replicated four times with row to row and plant to plant spacing of 60 cm and 20 cm, respectively. The population of maize aphids initiated in the first week of August and remained active throughout the growing stage and reached to its peak in the second week of September. The mean aphid population had a significant positive correlation with mean atmospheric temperature in all the intercrop treatments. The correlation coefficient values in the different maize based planting patterns were: sole maize (r=0.76), maize + green gram (r=0.73), maize + black gram (r=0.66) and maize + soybean (r=0.63) except in maize + cowpea (r=0.26). The aphids showed a negative correlation with mean relative humidity; while, a positive correlation with total rainfall in the sole as well as intercrop treatments.
