The egg masses of litchi stink bug, Tessaratonla javanica (Thunberl:) were found parasitized by two very interesting egg parasitoids viz, Anastatus colemani Crawford (Hymenoptera: Eupelmidae) and Ooencyrtus phongi Tryapitsyn, Myartseva and Kostyukov (Hymenoptera: Encyrtidae). The two parasitoids offer great potential for the hiological control of litchi bug T. javanica. Ooencyrtus phongi is being reported for the first time from India. The egg parasitization by A. colemani and O. phongi ranged from 12.9 to 52.9 per cent and 20.6 to 55.7 per cent, respectively during tbe study period. The sex-ratios of the A. colemani and O. phongi ranged from 1:1.83 to 1:4.14 and 1:1.35 to 1:3.83, (male: female), respectively.

The egg masses of litchi stink bug, Tessaratonla javanica (Thunberl:) were found parasitized by two very interesting egg parasitoids viz, Anastatus colemani Crawford (Hymenoptera: Eupelmidae) and Ooencyrtus phongi Tryapitsyn, Myartseva and Kostyukov (Hymenoptera: Encyrtidae). The two parasitoids offer great potential for the hiological control of litchi bug T. javanica. Ooencyrtus phongi is being reported for the first time from India. The egg parasitization by A. colemani and O. phongi ranged from 12.9 to 52.9 per cent and 20.6 to 55.7 per cent, respectively during tbe study period. The sex-ratios of the A. colemani and O. phongi ranged from 1:1.83 to 1:4.14 and 1:1.35 to 1:3.83, (male: female), respectively.
