 ABSTRACT

Leaf miner, Aproaerema modicella (Deventer) and leaf bud borer, Anarsia ephippias (Meyrick) are the two insect pests belonging to the family Gelechiidae causing considerable yield losses. An experiment was conducted to study the mechanisms of resistance on different groundnut genotypes towards groundnut leafminer. Groundnut genotypes tested for their reaction to leaf miner revealed that the proteins had shown significant negative correlation with incubation period, fourth instar duration, fifth instar duration, and total larval duration and total life span, phenols showed a significant positive correlation with third instar duration, fourth instar duration, total larval duration and total life span and reducing sugars showed positive correlation with incubation period and total life span.

Keywords: Groundnut leaf miner, Proteins, Phenols, Reducing sugars.
