Abstract

The incidence of leaf miner, A. modicella (maximum 0.02 larvae/plant in 32nd MW), S. litura (maximum 0.33 larvae/plant in 32nd & 35th MW) and H. armigera (maximum 0.66 larvae/plant in 32nd mw) was very low/negligible. the girdle beetle, O. brevis incidence started in 30th MW by recording 1.36% infestation which at harvest reached 61.22% whereas stem tunneling observed due to stemfly at physiological maturity was 59.45%. Green semiloooper, G. gema recorded a peak of 3.00 larvae/mrl during 34th MW. the infestation of O. brevis in relation to bright sunshine hours (0.714*) was positively significant and negatively significant with wind velocity (−0.674*). the population of G. gema in relation to wind velocity (r = 0.613*) was found positive and significant.
