Field experiment carried out at the Entomology Instructional Farm, JNKVV-College of Agriculture Rewa, MP during rabi season 2018-19 revealed that incidence of the chickpea pod borer Helicoverpa armigera. Population range of pod borer during different weather weeks varied between 0.30 and 1.89 larvae/mrl (April 2nd week and March 2nd week respectively). Peak larval population of Helicoverpa armigera was recorded in 2nd week of March (11 standard weeks). A weak negative correlation was observed with the maximum relative humidity and minimum relative humidity correlation, -0.172 and -0.595 respectively and a non significant positive correlation with maximum temperature, minimum temperature and rainfall. The respective r was found to be 0.306, 0.391 and 0.269. In district Rewa, MP, India the insect-pests of chickpea and their natural enemies during rabi the total seven species was recorded in Chickpea in which six pests minor in nature and one major pest Chickpea pod borer (Helicoverpa armigera). Termite (Odontotermes obesus Ram.), White grub (Holotrichia consanguinea Bl.), Black aphid (Aphis craccivora Koch), Grasshopper (Chrotogonus trachypterus Blan.), Semilooper (Autographa nigrisigna L.), Cut worm (Agrotis ipsilon Huf.) are minor in nature. Seven natural enemies found during field investigation i.e. lady bird beetle (Chilomenes sexmaculata Fab.), lady bird beetle (Coccinella septempunctata L.), Praying mantis (Mantis religiosa), Dragon fly (Crocothemis servilia Drury), Campoletis parasitoid (Campoletis chlorideae Uch.), Indian mynah (Acridotheris tristis L.), King crow (Dicrurus macrocerus Vie.) in chickpea observed in low to medium population on the crop and to help in reduction of pest population.
