How tyramine β-hydroxylase controls the production of octopamine, modulating the mobility of beetles [PDF]

open access: yes, 2018
Biogenic amines perform many kinds of important physiological functions in the central nervous system (CNS) of insects, acting as neuromodulators, neurotransmitters, and neurohormones.

Heating up parasitoid–host interactions: High temperature increased mortality of late‐instar braconid larvae and reduced ladybird recovery rate

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 773-785, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract With ongoing climate change, temperature‐dependent outcomes of host–parasitoid interactions can affect ecosystem functioning and key ecosystem services such as biological control. However, most studies addressing the impacts of temperature on host–parasitoid systems are

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.

Fitness benefits of trypsin proteinase inhibitor expression in are greater than their costs when plants are attacked. [PDF]

open access: yes, 2004
Background The commonly invoked cost-benefit paradigm, central to most of functional biology, explains why one phenotype cannot be optimally fit in all environments; yet it is rarely tested.

Diel thermal variability does not always have detrimental effects on the performance of ectotherms

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 786-799, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change directly affects animal survival, with ectotherms being particularly vulnerable because their vital rates are closely related to environmental temperatures.

α-Cyclodextrin extracts diacylglycerol from insect high density lipoproteins

open access: yesJournal of Lipid Research, 2000
α-Cyclodextrins are water-soluble cyclic hexamers of glucose units with hydrophobic cavities capable of solubilizing lipophiles. Incubating α-cyclodextrin with high density lipophorin from Manduca sexta or Bombyx mori resulted in a cloudy, turbid ...

A senior moment: What is the program of programmed cell death?

open access: yesCell Communication and Signaling
A previously generated sequence of putative mRNA from intersegmental muscles of Manduca sexta moths just before the death of the muscles has been identified as the N-terminal sequence of a copper chaperone for superoxide dismutase.

Characterisation of Bombyx mori odorant-binding proteins reveals that a general odorant-binding protein discriminates between sex pheromone components [PDF]

open access: yes, 2009
In many insect species, odorant-binding proteins (OBPs) are thought to be responsible for the transport of pheromones and other semiochemicals across the sensillum lymph to the olfactory receptors (ORs) within the antennal sensilla.

Lipophorin of the larval honeybee, Apis mellifera L.

open access: yesJournal of Lipid Research, 1985
Most insects have a major lipoprotein species in the blood (hemolymph) that serves to transport fat from the midgut to the storage depots in fat body cells and from the fat body to peripheral tissues.
