“…This proboscis extension response (PER) first reflects the integration of gustatory perception and motivation for sugar and then allows feeding. Sucrose-elicited PER has been described and involved in associative learning in restrained insects including moths (Hartlieb, 1996; Fan et al, 1997; Hartlieb et al, 1999a,b; Fan and Hansson, 2001; Skiri et al, 2005; Jorgensen et al, 2007), butterflies (Kroutov et al, 1999), bees (Menzel, 1999, 2012; Page and Erber, 2002; Sandoz, 2011; Giurfa and Sandoz, 2012; Giurfa, 2015) and flies (Fresquet, 1999; Chabaud et al, 2006); similar feeding-related responses exist in ants (Guerrieri and d’Ettorre, 2010; Perez et al, 2013), crickets (Matsumoto et al, 2015), and bugs (Vinauger et al, 2013; Labrousse et al, 2017). PER has been used by Scheiner and her colleagues to assess responsiveness to sucrose in bees and flies (Scheiner et al, 2004a,b, 2013; Mujagic et al, 2010).…”

Adult moths need energy and nutrients for reproducing and obtain them mainly by consuming flower nectar (a solution of sugars and other compounds). Gustatory perception gives them information on the plants they feed on. Feeding and food perception are integrated in the proboscis extension response, which occurs when their antennae touch a sugar solution. We took advantage of this reflex to explore moth sugar responsiveness depending on different parameters (i.e., sex, age, satiety, site of presentation, and composition of the solution). We observed that starvation but not age induced higher response rates to sucrose. Presentation of sucrose solutions in a randomized order confirmed that repeated sugar stimulations did not affect the response rate; however, animals were sometimes sensitized to water, indicating sucrose presentation might induce non-associative plasticity. Leg stimulation was much less efficient than antennal stimulation to elicit a response. Quinine prevented and terminated sucrose-elicited proboscis extension. Males but not females responded slightly more to sucrose than to fructose. Animals of either sex rarely reacted to glucose, but curiously, mixtures in which half sucrose or fructose were replaced by glucose elicited the same response rate than sucrose or fructose alone. Fructose synergized the response when mixed with sucrose in male but not female moths. This is consistent with the fact that nectars consumed by moths in nature are mixtures of these three sugars, which suggests an adaptation to nectar perception.

“…Wigglesworth and Gillett (1934a, b) were unable to elicit proboscis extension in R. prolixus using mouse skin. According to Vinauger et al (2013) "heat constitutes the only necessary and sufficient signal to trigger" what they called the proboscis-extension response (Flores and Lazzari 1996;Labrousse et al 2017). These studies recognized proboscis extension as an innate behavior, which they labeled a Fig.…”

Triatomines (Heteroptera, Reduviidae) are vectors of Trypanosoma cruzi, the etiological agent of Chagas disease in America. These true bugs have traditionally been considered to be blood suckers, although some species have been catalogued as being entomophagous. By using their highly specialized mouthparts, these insects have evolved a stereotyped habit which includes lifting up the proboscis, piercing and sucking, when the occasion arises. Most triatomines bite their sleeping and unaware vertebrate or invertebrate hosts, but they can also search for other targets, guided, in part, by visual and chemical stimuli. In this study, we observed that triatomines apparently visually identify a drop of water in the distance, then taste it with their legs, upon which proboscis extension and sucking ensues. This invariant behavior or fixed action pattern, observed in several triatomine species (Rhodnius prolixus, Triatoma infestans and Panstrongylus geniculatus), was also elicited by a dummy drop of water and guava fruit. We discuss evolutionary and ethological aspects of this innate behavior.

BACKGROUNDIn the field, we observed that many white‐backed planthoppers (Sogatella furcifera, WBPHs) stayed in the top region of rice plants exposed to direct sunshine. It was known that WBPHs frequently took flight when the ground temperature was about 25 °C, then climbed to and flew in a dense layer corresponding to an air temperature of about 16 °C in the sky. Its migration height was higher than the top of the surface temperature inversion. It is still unclear whether WBPHs prefer warm or cold regions, and therefore we studied the thermal responses of WBPHs and other insects using a simulated system.RESULTSWe found that WBPHs preferred a cold region to a warm one, unexpectedly below their comfort temperature zone. After comparative analysis with other insect species, such as small brown planthoppers, brown planthoppers, Trialeurodes vaporariorum (stinkbugs, a predator of planthoppers) and Bemisia tabaci (whitefly), only three planthoppers showed cold preference behavior. RNA interference experiments revealed that this behavior of WBPHs can be regulated by the transient receptor potential (TRP) channels TRPA1 channel. Furthermore, podocarpic acid, an agonist of TRPA1, weakened the cold preference, whereas A‐967079, an antagonist of TRPA1, had the opposite effect.CONCLUSIONWe reported a novel cold preference (negative thermotaxis) in rice planthoppers that was regulated in WBPHs by the TRPA1 channel. Cold preference of rice planthoppers is probably related to its choice behavior of the special migratory temperature layer. Our results expanded a new perspective to develop novel strategies for behavioral manipulation and management of rice planthoppers. © 2020 Society of Chemical Industry
