Abstract
The influence of the age of host (Chile partellus) pupae on parasitoid Pediobius furvus fecundity, developmental period, progeny production, and sex ratio is reported. The extent of parasitism was determined fr om the proportions of parasitoid emergence to host adults recorded. Ho st age was found to be an important factor in development of immature of P. furvus with greater emergence from younger hosts, and C. partell us pupae over 5-day-old being rejected by the gravid female parasitoid . The result showed that both acceptability and suitability of C. part ellus pupae drop off after 2 days, and to zero after 4 days. However, the host ages that are accepted by the parasitoid appear to be fairly wide.
