Abstract Litchi stink bug, LSB (Tessaratoma javanica) is a major insect pest of litchi in India and insecticidal control of this pest is non effective. Therefore, in present study, exploration of natural enemies of litchi stink bug and their effect on pest population was investigated for two years during 2012 and 2013. The LSB females were found to start laying eggs from February and peak activity was recorded in the month of March to April during both years. Three egg parasitoids of litchi stink bug were recorded, two were from the family Eupelmidae and one was from the family Encyrtidae of order Hymenoptera. Among parasitoids recorded, only two were identified up to species level namely Anastatus bangalorensis and Anastatus acherontiae. We are reporting these two parasitoids as new record from litchi stink bug (T. javanica). Maximum parasitized eggs were found in the month of March with 42.54% and 46.12%, respectively in insecticides free litchi orchard during 2012 and 2013 with major parasitization by A. bangalorensis. The egg parasitoids of litchi stink bug would be beneficial in the integrated management of the pest if mass reared and released in the litchi orchards.
