The infestation of slug caterpillar, Parasa lepida (L.)and its relation to weather parameters on different varieties of mango was carried out at Horticultural Instructional Farm, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during 2015. The population of P. lepidawas started from 4th week of May and remained active upto December on mango. The maximum (26.4 percent) infestation of P. lepida was recorded during 35th standard week (fourth week of August) in the variety Rajapuri. The minimum (1.1 percent) infestation of P. lepida was recorded during 47th standard week (fourth week of November) in the variety Alphanso. From the study, it can be seen that mango variety Rajapuri was more preferred by P. lepida as compare to Alphanso. The study on weather parameter in relation to infestation of P. lepidait can be concluded that when the temperature increased infestation of P. lepidaalso increased and vice versa in the Rajapuri, Kesar and Langda varieties of mango. The varieties Dasheri, Amrapali and Alphanso had significant positive correlation with the temperature. Further, relative humidity and rainfall had no effect on infestation of P. lepida.
