The role of low levels of juvenile hormone Esterase in the metamorphosis of Manduca sexta

open access: yesJournal of Insect Science, 2001
The activity of juvenile hormone esterase (JHE) in feeding fifth instar larvae of Manduca sexta increases gradually with larval weight and rises to a peak after larvae pass the critical weight when juvenile hormone secretion ceases.

Innate food preference in the larval tobacco hornworm, Manduca sexta [PDF]

open access: yes, 2017
Food preference can drive an organism to seek a specific food source even if another food, which can provide needed nutrition, is easier to obtain. Food preference can develop in different ways, including innate preference, i.e., organisms display food ...

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

Feeding-induced rearrangement of green leaf volatiles reduces moth oviposition

open access: yeseLife, 2013
The ability to decrypt volatile plant signals is essential if herbivorous insects are to optimize their choice of host plants for their offspring. Green leaf volatiles (GLVs) constitute a widespread group of defensive plant volatiles that convey a ...

The main triglyceride-lipase from the insect fat body is an active phospholipase A1: identification and characterization

open access: yesJournal of Lipid Research, 2006
The main triglyceride-lipase (TG-lipase) from the fat body of Manduca sexta has been identified as the homolog of Drosophila melanogaster CG8552. This protein is conserved among insects and also shares significant sequence similarity with vertebrate ...
