dispersal/host searching capacity of Trichogramma chilonis Ishii and Trichogramma
japonicum Ashmead was studied in organic Basmati rice during 2012
and 2013. Results showed that the level of parasitism was negatively
correlated with the distance between host eggs and parasitoids' release
point. Parasitisation rate was more (11.39-18.10% and 9.77-15.49% by T.
chilonis and T. japonicum, respectively) near the release point
(1-3m) with maximum parasitism at 1m by both the parasitoid species. A very
low parasitism (0.05-0.47%) was recorded up to the distance of 8-9 m in two
species. Among the two parasitoid species, T. chilonis showed higher
parasitism (up to 18.10%) in different distance treatments in comparison to T.
japonicum (up to 15.49%). ?????
