dc.description.abstractThe studies on occurrence and control of insect pests on pigeonpea were conducted during the year 1994-95 under field conditions at Agricultural College Farm, Bapatla. The data with regard to the occurrence of pests indicated that the leaf roller and the leaf miner were confined mostly to preflowering stage and their peak infestation synchronising with peak vegetative growth. November and December months are favourable for their multiplication on pigeonpea. The sucking pest, cow bug appeared during vegeta— tive stage in late November and the pod bug appeared during mid December, and both the pests remained in the field up to the end of the season with their peak during January. Flower feeding blister beetles appeared during first fort— night of January with the on set of blooming and remained up to the third week of February. 'Among the pod borers the gram caterpillar and the spotted pod borer appeared during first fortnight of January where as the plUme moth larvae during second fortnight of January. Early February month was found favourble for the borers. Among the different NPK sources, FYM was most effective and was followed by combination of FYM and inor— ganic straight fertilizer in 50:50. Inorganic form of NPK application was least effective in maintaining the population of gram caterpillar, spotted pod borer, plume moth, bister beetle and pod bug at low level. Pod damage by pod borer complex and seed damage by pod fly also followed the same trend. Insecticidal control indicated that fenvalerate 0.01% was the most effective in bringing down the pest population. The next best treatment was profenofos 0.05% and methomyl was the least effective among tfe insecticidal treatments. Fenvalerate recorded maximum yield and was followed by profenofos and methomyl.en_US
