Complete Metamorphosis in Manduca sexta Involves Specific Changes in DNA Methylation Patterns

open access: yesFrontiers in Ecology and Evolution, 2021
The transition between morphologically distinct phenotypes during complete metamorphosis in holometabolous insects is accompanied by fundamental transcriptional reprogramming.

Innate olfactory preferences for flowers matching proboscis length ensure optimal energy gain in a hawkmoth

open access: yesNature Communications, 2016
Foraging is energetically demanding for animals like hawkmoths that feed while flying. Here, Haverkamp et al. show that Manduca sexta has an innate preference for feeding on species of Nicotianawhose flower corolla length best matches the length of their

Lipid transfer from insect fat body to lipophorin: comparison between a mosquito triacylglycerol-rich lipophorin and a sphinx moth diacylglycerol-rich lipophorin

open access: yesJournal of Lipid Research, 1996
Two insect lipoproteins, triacylglycerol-rich Aedes aegypti lipophorin and diacylglycerol-rich Manduca sexta lipophorin, were compared in their ability to load neutral lipid from fat body. When fat body of M.

Pollinator risks and recovery from air pollutant interactions during the fossil‐fuel transition

open access: yesFrontiers in Ecology and the Environment, EarlyView.
By altering the composition and concentration of floral scents, air pollutants such as ozone (O3) and nitrogen oxides (NOx) disrupt the ability of insect pollinators to locate flowers, threatening biodiversity and crop production. We examine the impact of these pollutants on pollinator performance and evaluate the short‐ and long‐term consequences of ...

Lipoprotein biosynthesis in the larvae of the tobacco hornworm, Manduca sexta. [PDF]

open access: yesJournal of Biological Chemistry, 1986
Lipoprotein biosynthesis in larvae of the tobacco hornworm (Manduca sexta) was investigated. By immunoblotting, it was shown that the apoproteins are present in the fat body, but not in the midgut. Fat body incubated in vitro with [35S]methionine secreted labeled apoproteins.

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

open access: yesInsect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

Differences in nicotine metabolism of two Nicotiana attenuata herbivores render them differentially susceptible to a common native predator. [PDF]

open access: yesPLoS ONE, 2014
Nicotiana attenuata is attacked by larvae of both specialist (Manduca sexta) and generalist (Spodoptera exigua) lepidopteran herbivores in its native habitat. Nicotine is one of N. attenuata's important defenses. M.

A Smelly Conflict: The Role of Olfactory Information in the Interaction of Insect Herbivores and Their Natural Enemies

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Insect herbivores rely on olfactory cues to locate natural‐enemy‐free spaces for feeding or ovipositing; conversely, natural enemies detect herbivores by chemical cues from damaged plants or from the herbivores themselves. Based on the reviewed findings, we suggest that herbivores and natural enemies converge towards using specific olfactory cues. This
