Abstract:
The chickpea pod borer, Helicoverpa armigera (Hübner) is an important insect pest of chickpea crop causing huge losses all over the world. Farmers generally rely on the use of conventional chemical insecticides to combat this pest but pest has been reported toshow resistance against these insecticides. Host plant resistance formanaging this pest is best as it is compatible with other pest management practices. Thechickpea plant was observed to have certain morphological characters which reduce the preference of the pod borer. At the same time, meteorological factors also play a key role in pest infestation during the cropping season.In the current study, physio-morphic characteristics viz. pod trichomes density, pod wall thickness and chlorophyll contents of leaves of nine chickpea genotypes were evaluated.The results revealed that pod wall thickness and pod trichomes density negatively correlated with the pod borer population and percent pod damage but positively correlated with chlorophyll contents of leaves. Larval population and percent pod borer damage differed significantly among the genotypes with PCK-16027 having lowest larval population (0.97 larvae/plant) and percent damage (11.05 pods). Highest larval population was recorded on PCK-17030 (2.22 larvae/plant) with percent pod damage (15.28 pods). Pod trichomes density, pod wall thickness and chlorophyll contents of leaves were also differed significantly among the genotypes. Abiotic factors such as temperature and humidity also play a fundamental role in changing the crop pest infestation. Data revealed that temperature had a positive relation with the pod borer population while relative humidity had a negative relationship.
