A. Morales-Ramos, M. G. Rojas, E. G. King] The effect of different concentrations of fructose and glucose on the longevity of the boll weevil, Anthonomus grandis grandis Boheman, ectoparasitoid Catolaccus grandis (Burks) was tested. Parasitoid females feeding sugar concentrations of 30% had a significantly increased longevity compared with females feeding 50 and 70% sugar solutions. Host-feeding on boll weevil larvae did not significantly increase longevity. In the absence of a carbohydrate source, host-feeding was ineffective maintaining C. grandis alive for >2.5 d. Dissections showed that C. grandis is a synovigenic and autogenous parasitoid, but providing C. grandis females with diets supplemented with amino acids and boll weevil haemolymph did not increase oögenesis. Females with oviposition experience, on the other hand, produced 4 times as many eggs as did inexperienced females regardless of the quality of the adult diet provided. However, adult nutrition was important for egg production after host contact. Catolaccus grandis females experienced in oviposition produced significantly more eggs when a supplemental diet was provided in the absence of host-feeding opportunities. Exposure of the parasitoids to encapsulated weevil larvae for at least 2 d before the field release is recommended. © 1996 Entomological Society of America Physiology, Biochemistry, and Toxicology nationallicence boll weevil nationallicence host-feeding nationallicence parasitoid nationallicence nutrition nationallicence oogenesis nationallicence diet nationallicence Morales-Ramos J.
