Studies conducted to investigate the impact of differently coloured cards, used for fixing the host Corcyra eggs, on the biological attributes of T. chilonis indicated that under multiple choice condition, the per cent parasitism differed significantly on egg cards of different colours. Maximum parasitism (64.75%) was found on mint green coloured egg cards, followed by jade green (56.75%) and golden yellow cards (54.25%). However, the per cent adult and female emergence in differently coloured egg cards did not vary significantly from each other. In case of single choice condition, the maximum per cent fecundity was recorded on mint green (87.50), followed by deep orange (87.33) and golden yellow (87.17).
