Abstract

Attempts were made to correlate the moth catches in the light trap with field incidence of groundnut leaf miner. The light trap catches exerted a positive correlation with the field incidence, Among the three generations in a crop period, third genera- tions accounted for the maximum field incidence for a unit increase of the number of moths in the light trap. The value was higher whenever the mean incidence of six observations in a sowing was considered for correlation, compared with the mean incidence at each observation in the different sowings. The number of moths caught was at its peak during the second week of October and highest incidence was observed in the first week of November.
