Investigations on studies of aphid on brinjal and chilli and host plant resistance studies were carried out during 2020 in vallampadugai village, Tamil Nādu, India. Significant difference was observed between the brinjal and chilli local variety in length, thickness, breath was positive correlated and trichome density and trichome length and types were negatively correlated. Biochemical component of resistant plants is sugar, nitrogen was positively correlated, and phenol, potash and silica were negatively correlated with aphid feeding preference.
