“…Feeding every 3 days was not sufficient because C. glomerata died as quickly as starved wasps in three of four comparisons (flower every 3 days versus water or control , Fig 2a,b). Similary, Aphidius ervi (Haliday) died quickly when fed every 3 days, and even required feeding twice a day, as feeding once per day decreased lifespan by one-sixth (Azzouz et al, 2004).…”

“…Providing sugar in water solution is far more beneficial than solid sugar with water (Wä ckers 2000;Pinto et al 2005). Recently, the optimal frequency of feeding, and lifespan gain from one sugar meal/day has been examined for various parasitoids (Siekmann et al 2001;Azzouz et al 2004;Fadamiro et al 2005). A 100 lg intake of sucrose extends the lifespan of C. glomerata by 50 h (Hausmann et al 2005).…”

This study examined how water, sucrose, and frequency of nectar availability affects the longevity of the parasitoid Cotesia glomerata (L.) (Hymenoptera: Braconidae). Under standard laboratory conditions, water did not extend longevity in the absence of sugar in three out of four comparisons, nor did it extend longevity with access to nectar. Cotesia glomerata lived 2-3 days when given water or nothing, 8-15 days when given buckwheat (Fagopyrum esculentum Moench) nectar daily with or without water, and 23-26 days when given a 50% sucrose solution. The lifespan of C. glomerata fed flowers every other day was one-third shorter than that of C. glomerata fed flowers every day, but this difference was not statistically significantly. Only minimal benefits occurred when flowers were given every 3 days.

“…However, feeding time of a food item may not accurately reflect its intake (Siekmann et al, 2001;Wäckers, 2001;Azzouz et al, 2004;Wyckhuys et al, 2008). Therefore, we first examined the relationship between feeding time and intake of the sucrose, glucose, fructose and maltose solutions.…”

We examined gustatory responses of the larval parasitoid Microplitis croceipes to determine whether the adults discriminate among common sugars, including fructose, glucose, maltose and sucrose, found in plants. When given single sugar solutions of sucrose, glucose, fructose and maltose at concentrations of 0.008-2.0 mol l −1 , the estimated concentrations at which 50% of wasps initiated feeding ranged between 0.054 and 0.085 mol l −1 for sucrose, glucose and fructose, which was significantly lower than for maltose. Wasps showed a strong decrease in feeding time for maltose or fructose following a brief exposure to other sugars, suggesting that wasps can distinguish maltose and fructose from the other sugars tested. The higher acceptance threshold and short feeding time in the case of maltose appears adaptive in light of the relatively poor nutritional quality of the sugar in the longevity trial. The pronounced feeding inhibition seen for fructose following exposure to other sugars is not linked with lower nutritional performance. This feeding inhibition was even seen in wasps that had fed on glucose at the lowest acceptance threshold (0.031 mol l ) and persisted for 24 h. This study is the first to show feeding inhibition of otherwise phagostimulant sugars such as maltose and fructose after gustatory stimulation on other sugars.
