T
he present investigation on Abundance of natural enemies associated with Rhopalosiphum maidis (Fitch) in maize
based planting system 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 coccinellids appeared in first week of August and thereafter gradually
increased with aphid population reaching to its peak in second week of September, 2017. The maximum seasonal mean
population of coccinellids was recorded inmaize + cowpea (5.09 aphids/ plant).Themean population of coccinellids had a
significant positive correlationwithmean atmospheric temperature in all the intercrop treatments.The predation of aphids
by the larval population of syrphid fly maggots was observed from the first week of August, in the maize + greengram,
maize + blackgram and maize + cowpea; while, in sole maize and maize + soybean the predation began in second week of
August. The maximum seasonal mean population of syrphid fly maggots was recorded in maize + cowpea (2.00 maggots/
plant).
