Sex pheromones in mate assessment: analysis of nutrient cost of sex pheromone production by females of the mothHeliothis virescens

“…If one considers that the amount of glucose (18.8 µg) in the 75% feed was roughly 10 times that in hemolymph trehalose before feeding [ca. 2 µg, assuming 50 µl volume, as for the similar size Helicoverpa zea (Bushman et al, 2002), at ca. 20 mmol l −1 (Foster, 2009)], then this suggests that the contribution of AAC to pheromone production is largely replacing the contribution of larval-acquired trehalose.…”

Tracing sources of carbon and hydrogen to stored lipids in the migratory moth, Mythimna unipuncta using stable isotopes (δ2H, δ13C)

“…It is known that there are differences between the δ 2 H and δ 13 C values of the ingested dietary carbohydrates and the lipids ultimately metabolized (DeNiro & Epstein, 1977; Chamberlain et al ., 2004), with the degree of isotopic change depending upon the number of metabolic steps involved (Overmyer et al ., 2008; Newsome et al ., 2010; Vander Zanden et al ., 2016). In insects, lipid synthesis from carbohydrates requires many steps involving various enzymes (Sacktor, 1970; Crabtree & Newsholme, 1975; Bushman et al ., 2009), so, given such a complex biochemistry, it has not been clear if lipid isotope values can be consistently linked to the environments where they were produced.…”
