“…This suggests a synergetic effect between glucose and fructose on the feeding response of female A. gambiae that is mediated by the sucrose taste neurone in the labellar trichoid T1 sensillum, a phenomenon already described for the blowfly Phormia regina (Dethier et al, 1956;Omand and Dethier, 1969) and the mosquitoes Culiseta inornata (Schmidt and Friend, 1991) and A. aegypti (Ignell et al, 2010). The fact that the sucrose labellar neurone of A. gambiae is activated by sucrose or by a mixture of glucose plus fructose but not by glucose or fructose alone suggests that it expresses distinct domains for glucose and fructose that both require activation to obtain a response from the neurone.…”

, but not by the same concentrations of caffeine. In conclusion, sucrose stimulates feeding and activates the labellar sucrose neurone, whereas feeding deterrents inhibit both the sucrose and water neurones. This study provides an initial understanding of the physiological mechanisms involved in sugar feeding in A. gambiae and shows how some bitter products interfere with it.Supplementary material available online at

“…As is known, sweet stimuli are important for feeding behaviour, as reported for instance in Rhagoletis indifferens (Yee 2003) and Phormia regina (Dethier et al 1956); in contrast, salty stimuli are fundamental for the regulation of electrolyte homeostasis (Lindemann 1996;Hiroi et al 2004).…”

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae), is a polyphagous pest in horticulture, mainly targeting pomaceous and citrus fruits. To gain better knowledge about its chemosensory system related to taste, essential for behavioural strategies and localisation of host plants, we examined the tarsal external morphology by highresolution scanning electron microscopy, focusing on sensilla. Numerous trichoid and chaetica sensilla, related to taste and mechanoreceptor systems, and other types of sensilla are present in tarsal segments. The responses of specific trichoid chemosensilla were also studied through electrophysiological experiments by stimulation with sodium chloride, fructose and four bitter stimuli. Electrophysiological data allowed us to distinguish three types of different neurons: high ("H"), middle ("M") and small ("S"). Increasing concentrations of sodium chloride enhanced the activity of H cells, while fructose boosted M cells activity. On the contrary, S cells showed no increase in spike activity after stimulation with these substances. Bitter stimuli induced no significant response on these cells. Behavioural assays showed no statistical difference among the responses to sugars, bitter substances and citric acid. Our results on taste stimuli will be useful in increasing knowledge of Ceratitis chemoreception, fundamental in new integrated pest management.

“…In the winter mosquito C. inornata, sucrose is the best sugar feeding stimulant followed by melezitose and an equimolar mixture of glucose and fructose (Schmidt and Friend 1991). Glucose and fructose also show synergism in the feeding responses of the yellow fever mosquito, A. aegypti (Ignell et al 2010), and of the blowfly Phormia regina (Dethier et al 1956). …”

Sugar-sensitive neurone responses and sugar feeding preferences influence lifespan and biting behaviours of the Afrotropical malaria mosquito, Anopheles gambiae

Floral nectar is the main source of carbohydrates for many insects including mosquitoes. Nonetheless, the physiological mechanisms underlying feeding on carbohydrates by the Afrotropical malaria mosquito Anopheles gambiae remain poorly understood. Here, we tested whether sugar sensitivity and sugar feeding preferences correlate with longevity in A. gambiae. We also tested whether feeding females on different sugar diets influences their biting behaviours. Electrophysiological recordings show that sugar neurones on the labella of females are most sensitive to sucrose, mixtures of glucose and fructose, and to melezitose; other sugars tested, including glucose and fructose presented alone, only weakly activate these taste neurones. Mosquitoes survive longest on sucrose, the most preferred sugar. Whereas feeding on a mixture of glucose and fructose is preferred over fructose or glucose alone, fructose supports higher longevity than either glucose or the mixture of the two hexoses. Females that had previously fed on glucose show a stronger biting response than those fed on sucrose, perhaps in an effort to compensate for their lower energetic state. These findings contribute to our understanding of the physiological basis of sugar feeding in A. gambiae and indicate how the sugar diet can affect laboratory-reared A. gambiae biting behaviours.
