Effect of four types of honey on longevity and reproduction of Catolaccus grandis (Hymenoptera:Pteromalidae)

The aim of this work was to investigate the best type of honey in relation to longevity and life fertility of Catolaccus grandis. Recent emerged adults were transferred to 500ml plastic recipients adapted to supply water and moisture to insects. A couple of parasite was kept for each recipient in climatic chamber at 25±1°C, RH = 70±10% and photofase 14h. The work had four treatments: orange, wild plant species honey, Jatai Tetragonistica angustula and sugar cane honey with fifteen replications each. Recent emerged adults received five Euscepes postfasciatus larvae, which were encapsulated in parafilm. Three drops of honey from respective treatment were placed on parafilm. Longevity of males and females were calculated, as well as the number of eggs female-1. Tables of fertility were made. The best diets to feed adults of C. grandis were wild plant species honey and orange honey; the best fecundity was observed on orange honey diet (101,60 eggs female-1) and the parameters of life fertility table were obtained using diets based on orange honey and wild plant species honey.
