    abstract = {The control of <I>Callosobruchus maculatus</I> F. on cowpea seeds was studied in the laboratory using <I>Dinarmus basalis </I>Rendani as parasitoid. Five pairs of adult <I>C. maculatus</I> were allowed to oviposit onto ten sets of cowpea seeds. Five pairs of <I>D. basalis</I> were introduced at 3 days intervals (beginning from the 6th day after oviposition) into each of the nine sets of seeds. No <I>D. basalis</I> was introduced into the tenth set (control). No significant differences (p 0.05) were observed in the number of eggs laid per female <I>C. maculatus</I> in all the sets and this ranged from 37.80-41.20. No significant (p 0.05) differences were observed on adult <I>C. maculatus</I> that emerged when <I>D. basalis</I> was introduced at the 6, 9 and 12th Day After Oviposition (DAO). Percent emergence was 0.59, 0.53 and 1.85% at 6, 9 and 12st day, respectively. <I>C. maculatus</I> emergence increased from 67.81% in the treatment that was inoculated on the 21st DAO to 74.48 % on the 30th DAO. The total <I>D. basalis</I> per female in each culture was 12.81 and 17.56% on the 6 and 15th  day  and  decreased  significantly to 11.78% when inoculation was done on the 30th day. Percentage mortality of <I>C.  maculatus</I>  increased  from 25.52 to 99.48% on the parasitised culture compared to 25.03 in the control. The time of introduction of the parasitoid critically affected the mortality of <I>C. maculatus</I>. Thus, introduction of <I>D. basalis</I> during the larval stage of <I>C. maculatus</I> caused higher mortality of the pest and had no effect on adult <I>C. maculatus</I>.}
