dc.description.abstractThe effect of host availability on Trichogramma cordubensis Vargas & Cabello (Hymenoptera, Trichogrammatidae) fecundity and survival rates was analyzed in this study. When hosts were daily provided (either with an unlimited or limited number), wasps had the highest rate of reproduction in the first day of parasitism, decreasing with oscillating values thereafter. When a limited number of hosts was provided with 3 days intervals, the parasitoids reproduction rate was significantly reduced, tending to be equally distributed throughout lifetime. A positive linear relation was found between reproduction and survival: wasps that had daily oviposited had greater longevity than those that had oviposited only every 3 days or did not oviposit. These results suggest that T. cordubensis is able to adjust fecundity schedule as an adaptation to changing hosts resources, which is an important survival feature for this species as host shortage is likely to occur in nature.por
