Abstract:
The field experiment was conducted at Potato and Temperate Fruits Research Station Mainpat, Surguja (C.G.) during Rabi season of 2022-23, to know the seasonal incidence of different insect-pests of potato along with their natural enemies. The incidence of Whitefly, Bemisia tabaci was first observed during 50^th SMW i.e., second week of December with 3.87 fly /plant then it gradually increased and the maximum number of flies was observed during 2^nd SMW i.e., second week of January with 4.00 fly /plant. The incidence of potato aphid, Myzus persicae was first observed during 49^th SMW i.e., maximum number of potato aphid, Myzus persicae was observed during 3^rdSMW i.e., third week of January with 14.13 aphid/plant. The tobacco caterpillar, Spodoptera litura revealed significant and negative correlation with maximum temperature (r= -0.635). The cutworm, Agrotis ipsilon revealed significant and negative correlation with morning relative humidity (r= -0.635). The major activity period of lady bird beetle was observed from fourth week of January, after that the infestation was declined.
