Additional Information



The groundnut leaf mine (GLM), aproaerema modicella (Deventer), is a serious pest of groundnut in peninsular India. Two distinct GLM population peaks, July-Sugust during the rainy season and Feb. -March during the post- rainy season, are common. Though it is sporadic, under epidemic situations GLM can cause complete crop loss, particularly severe in moisture-stress conditions. The identification of sex pheromone facilitate better monitor- ing than light traps, which were comparatively tedious. Several larval par- asitoides and predators have been found to control this pest effectively in nature. Among diseases, Metarrhizium anisopliae was observed to be a potential larval pathogen. In addition to ICGV 86031, a few other good sources of resistance have been identified. Meaningful control desicions are possible with economic thresholds based on crop phenology clubbed with the activity of natural enemies. Furthe studies on the cultural control, insect pathogens, hot-plant resistance, mass trapping, and mating disrup- tion effects of the pheromone are needed to strengthen the future integrat- ed pest management (IPM) program for GLM
