“…In Heliothis zea (Adler 1989;Lopez et al 1995) and the nymphalid butterflies V. indica and Argyreus hyperbius (Ômura and Honda 2003;Ômura et al 2008), food-sucking behavior is induced when the proboscis tip is stimulated with a sugar solution. When a sugar solution touches the proboscis tip, it moves up through the food canal by capillary action and stimulates the firing of the sugarreceptor neuron in the sensilla.…”

The feeding behavior in nectar-feeding insects is triggered by a sugar-receptor response in contact chemosensilla. The contact chemosensilla are distributed not only on tarsi and the outside of the proboscis but also on the inside of the food canal in Lepidoptera. Although the chemosensilla inside the food canal are assumed to detect sweet taste during the passage of nectar through the food canal, their electrophysiological function has received little attention. In the nectar-feeding Asian swallowtail butterfly, Papilio xuthus (Lepidoptera: Papilionidae), we found 15-to 30-μm-long sensilla neatly lined up along the inside galea wall, which forms the food canal in the proboscis. The receptor neurons of these sensilla responded to sucrose. We hypothesized that starch and sucrose compete with each other for a taste receptor site on the sensilla. When we added starch and sucrose to the food-canal sensilla, the electrophysiological responses of food-canal sensilla were inhibited in parallel with the food-sucking behavior of the butterflies. These results suggest that the food-canal sensilla are involved in the behavioral control of nectar-sucking in this butterfly species.

“…When feeding on decaying fruit, butterflies also imbibe fermentative products associated with the metabolic activities of the fungi, of which ethanol is the most prominent (Omura et al, 2000;Omura and Honda, 2003;Leavey, 2004). Depending on its concentration ethanol either serves as an energy source or as a toxin in Drosophila (Bokor and Pecsenye, 2000;Heberlein et al, 2004).…”

“…Further, the lack of effect suggests that ethanol, acting as a feeding cue in B. anynana and other Lepidoptera (e.g. Omura et al, 2000;Omura and Honda, 2003), does not increase intake rates which in turn may affect reproductive output.…”

It was generally believed that butterflies and other holometabolous insects rely primarily on reserves accumulated during the larval stage for reproduction. Recent studies, however, highlight the often fundamental importance of adult nutrition to realize the full reproductive potential. While the importance of carbohydrates is fairly well understood, the role of most other adult-derived substances is only partially resolved. We here focus on the effects of dietary lipids (cholesterol, polyunsaturated fatty acids) and fruit decay (dietary yeast, ethanol) on female reproduction in the tropical, fruit-feeding butterfly Bicyclus anynana (Nymphalidae). We found that banana-fed control females outperformed all other groups fed on sucrose-based diets. Lipids, yeast or ethanol added to a sugar solution did not yield a similarly high reproductive output compared to fruit-fed females. Groups fed fresh or decaying banana showed no differences in reproductive performance. As we could not identify a single pivotal substance, we conclude that resource congruence (the use of nutrient types in a specified ratio) rather than any specific nutrient component is of key importance for maximum reproductive output. Further, dietary quality may affect egg hatching success in spite of no obvious effects on egg size and number. Thus, any implications about potential fitness effects of different diets need to consider egg (and hatchling) viability in addition to fecundity. r

“…For instance, the probability that butterflies, bees and flies will extend their proboscis in response to taste stimulation increases with sugar concentration (Dethier, 1976;Schoonhoven and van Loon, 2002;Omura and Honda, 2003;de Brito Sanchez et al, 2005;Dahanukar et al, 2007;Gordon and Scott, 2009;Zhang et al, 2010). Likewise, the rate at which lepidopteran caterpillars either bite from disks (Ma, 1972) or swallow solutions (Sasaki and Asaoka, 2006) increases with sugar concentration.…”

Not all sugars are created equal: some mask aversive tastes better than others in an herbivorous insect

SUMMARY Manduca sexta caterpillars are unusual because they exhibit strong peripheral gustatory responses to sugars, but nevertheless fail to show immediate appetitive responses to them. We hypothesized that the primary function of the peripheral gustatory response to sugars is to mask the taste of noxious compounds, which abound in host plants of M. sexta. We compared 10 s biting responses to water with those to mixtures of a noxious compound [caffeine (Caf) or aristolochic acid (AA)] and various combinations of sugars [i.e. sucrose (Suc), glucose (Glu), inositol (Ino), Suc+Glu, Suc+Ino or Glu+Ino]. The biting assays indicated that the aversive taste of AA was completely masked by Suc+Ino, and partially masked by Suc+Glu, Glu+Ino and Suc, whereas that of Caf was completely masked by Suc+Ino and Suc+Glu, and partially masked by Glu+Ino, Suc and Ino. To examine the contribution of the peripheral taste system to the masking phenomenon, we recorded responses of the maxillary gustatory sensilla to each stimulus mixture. The sugars differed greatly in their capacity to suppress peripheral gustatory responses to AA and Caf: Suc+Ino and Suc+Glu produced the greatest suppression, and Glu and Ino the least. Further, the extent to which each sugar stimulus suppressed the peripheral gustatory responses to AA reliably predicted the extent to which it masked the taste of AA in biting assays; no such predictive relationship was observed for the sugar/Caf mixtures. We conclude that some, but not all, sugars act on both peripheral and central elements of the gustatory system to mask the taste of noxious compounds.
