| Abstract | ||||
| Laboratory feeding is an effective factor for T. evanescens efficiency. Mainly, mass-rearing programs rely on sugar requirements in parasitoid nutrition. In this study, different carbohydrates sources were evaluated on the biological parameters of T. evanescens (Westwood) under laboratory conditions. Females fed on sugar cane honey; Pritchardia dates honey and licorice roots extract had the highest fecundity, produced the highest rates of emerged individuals, lived the longest days, and produced the highest rates of females in progeny than those fed on 10% sucrose solution. While starved females had the lowest fecundity and the produced adults emergence rates, lived the shortest days and produced the lowest rates of females. Generally, the highest general productivity was produced when T. evanescens females fed on sugar cane honey, Pritchardia dates honey and licorice plant extract. This finding implies that alternative carbohydrates sources could be introduced as diets in mass-rearing programs of T. evanescens for improving their performance in fields. | ||||
