How tyramine β-hydroxylase controls the production of octopamine, modulating the mobility of beetles [PDF]
Biogenic amines perform many kinds of important physiological functions in the central nervous system (CNS) of insects, acting as neuromodulators, neurotransmitters, and neurohormones.

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
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]
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
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
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?
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]
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.
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.
