Abstract

Observations on the seasonal incidence of the tomato pin worm Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) revealed that the occurrence was less during early stage of the crop, but later increased. The effect of weather factors evaluated during 2017–18 to 2018–19 revealed a positive correlation with the maximum temperature, and a negative one with relative humidity and rainfall.
