Abstract- It has been classified that mechanisms of resistance into 3 main categories Antixenosis (Non preference) Antixenosis is mechanism employed by the plant to deter or reduce colonization by insects. Plants that exhibit antixenotic resistance should have a reduced initial number of colonies early in the season. Antibiosis Antibiosis operates after the insect have colonized and have started utilizing the plant. Tolerance Tolerance of the plant does not affect the rate of population increase of the target pest but does raise the threshold level.
Keywords-Tolerance, Non preference, Antibiosis , resistance
