Abstract

An experiment was conducted to evaluate 14new genotypes and released varieties of Pigeon Pea for their resistance or tolerance to bud Weevil Indoza cladustheresiae (Dolla Torre) under natural infestation in pesticide free field about one month prior to observation. In order to assess the degree of infestation 50 buds were randomly picked up from each replication. Bud weevil incidence was recorded with actual larvas inside the buds with the help of magnifying lense and digital USB microscope. On the basis of mean infestation among 14 treatments (4 checks and 10 genotypes) the genotype PT 0911-5-1-1 (5.67 %) and AKTE-1905 (5.67 %) followed by Rajeshwari (10.67 %), BDN 2013-41 (10.67 %) and BDN 2018-2 (10.67 %) were found to be less susceptible whereas genotype BDN-711 (40.67%) and BDN-716 (50.00%) were found to be most susceptible genotypes to bud weevil incidence released varieties
