| Résumé: | The objective of the research was to study sex ratio and oviposition sequence of egg parasitoid <em>Trichogramma chilotraeae</em> in relation with host density under laboratory condition. Parasitoid response with respect to oviposition sequence was examined by exposing five different host (egg) densities: 3, 6, 12, 24 and 48 on female parasitoids <em>T. chilotraeae</em>. Results showed that in general, female parasitoid laid its female progeny at the beginning of oviposition sequence. Host density was found to have a strong effect on sex ratio. Sex ratio increase with increasing of host number. |
