Seasonal incidence of A. modicella in groundnut was studied during rabi, 2015-16 at S.V. Agricultural College, Tirupati in two groundnut varieties i.e., Dharani and Kadiri-6 (K6). The results indicated that, the D3 (December second fortnight) and D4 (January first fortnight) sown groundnut crop, foliar damage due to leaf miner was high when compare with D1 (November second fortnight) and D2 (December first fortnight) sown crops during 6th standard week to 11th standard week of 2016.Weather parameters like wind speed showed a positive association with leaf miner incidence in terms of foliar damage and maximum temperature, minimum temperature showed a positive association with leaf miner incidence in D2, D3, D4 showed a negative association in D1. All the six weather parameters combinedly influenced the damage to the extent of 56 per cent (R2=0.566), 56 (R2=0.564) in D1 and58 per cent (R2=0.583), 48 percent (R2=0.482) in D2, 79 per cent (R2=0.79), 75 per cent (R2=0.75) in D3 and in D4 sown crop all the weather parameters were influenced the damage up to 66 and 69 per cent (R2= 0.66 and 0.69) in Dharani and K-6 respectively.
