Extent of parasitization by Trichogramma chilonis was tested for two consecutive years (2020-2021) at AICRP on Biological control, Regional Agricultural Research Station, Anakapalle, Andhra Pradesh, India by taking factitious host Corcyra cephalonica and Samia cynthia ricini to assess the predilection ethology towards host eggs whilst Trichogrammatids that developed after emerging from C. cephalonica preferred its eggs (85.00%) over erisilkworm eggs (72.33%) for parasitization under circumstances subjected to no choice Similarly, trichogrammatids that erupted from eggs of eri silkworm in the absence of free choice as well opted C. cephalonica eggs (80.00%), when compared to erisilkworm eggs (75.33%) for parasitization. Trichogramma chilonis parasitoids that emerged out from the eggs of rice moth documented higher percent egg parasitisation on rice moth eggs (91%) especially in contrast to eri silkworm eggs (71.33%) in free choice test, whilst the study of emergence pattern of T. chilonis from eri silkworm eggs has unveiled higher proclivity for parasitization of rice moth eggs (83.66%) contrary to eri silkworm eggs (73.66%). Although, the percent parasitization was comparatively higher in rice moth than eri silkworm egg on the other hand eri silkworm can still be used as a substitute as well an alternate host to rice moth in Trichogramma production as the size of eri silkworm egg (0.87±0.99 mm) is three times larger as well as it can accommodate more number of Trichogrammatids (9-10) than rice moth egg (0.34±0.38 mm) which accommodate only one trichogrammatid.
