Effect of some plant extract on Indian meal moth Plodia interpunctella (Hübner) (Lepidoptera: Pyrallidae) on Pistacio fruits in Erbil-Kurdistan Region

Abstract

In this study the Controlling of imature stages of Indian meal moth, Plodia interpunctella (Hübner) (Lepidoptera-Pyralidae) By botanical control were investigated in laboratory of Agricultural engineering Science Erbil Governorate, Kurdistan Regionon (2022). The natural insecticides (Urtica dioica, Ricinus communis, Lactuca seirola and Cephalaria setosa) were used to control the pest during larval instars. Crude plant extracts (Cephalaria setosa) with the highest mortality rate (73.94) % against the studied larval instar and crude plant extract Ricinus communis with mortality rate 72.27% against the studied larval instars, while in the crude plant extract Urtica diocia was the lowest mortality rate 50.69% against the studied larval stage of P. interpunctella (Hübner).
