Hexokinase Is Required for Sex Pheromone Biosynthesis in Helicoverpa armigera

Insects, 2021
Acetyl-CoA, the precursor of sex pheromone biosynthesis in Helicoverpa armigera, is generated from glycolysis. As the first speed-limited enzyme in glycolysis, Hexokinase (HK) plays an important role in acetyl-CoA production.

Scents and sex: Insect pheromones [PDF]

The Biochemist, 2009
Pheromones are chemical signals (semiochemicals) that act between members of the same species, sex pheromones being the signals that facilitate sexual reproduction. Many organisms use such semiochemicals, but it is insects to which the main research attention has been directed. This article will therefore concentrate on the insect sex pheromones.

Functional identification of the sex pheromone receptor MsepOR6 in the natural population of Mythimna separata (Walker)

浙江大学学报. 农业与生命科学版, 2023
In order to further understand the calling behavior of Mythimna separata (Walker) (Lepidoptera, Noctuidae) and explore the olfactory molecular recognition mechanism of male moths to intra- and inter-specific sex pheromones, the male moths collected by ...

Supplemental Sugar Is Required for Sex Pheromone Biosynthesis in Mythimna separata

Frontiers in Physiology, 2020
Supplemental nutrients of adult moths maximize moth fitness and contribute to the pollination of many plants. Previous reports have revealed that sugar feeding promotes to sex pheromone biosynthesis by increasing the haemolymph trehalose concentration in

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

, 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.

Exposure to Conspecific and Heterospecific Sex-Pheromones Modulates Gustatory Habituation in the Moth Agrotis ipsilon

Frontiers in Physiology, 2019
In several insects, sex-pheromones are essential for reproduction and reproductive isolation. Pheromones generally elicit stereotyped behaviors. In moths, these are attraction to conspecific sex-pheromone sources and deterrence for heterospecific sex ...

Female-induced increase of host-plant volatiles enhance specific attraction of aphid male Dysaphis plantaginea (Homoptera: Aphididae) to the sex pheromone [PDF]

, 2009
All aphid species studied so far share the same sex pheromone components, nepetalactol and nepetalactone. Variation by different enantiomers and blends of the two components released by different aphid species are limited and can only partially explain ...

Optimization of the sex pheromone-based method for trapping field populations of Phthorimaea operculella (Zeller) in South China

Journal of Integrative Agriculture, 2021
Despite the identification of the potato tuber moth Phthorimaea operculella (Zeller) sex pheromone, no effective application based on this pheromone has yet been developed and evaluated.

A carboxylesterase, Esterase-6, modulates sensory physiological and behavioural response dynamics to pheromone in Drosophila [PDF]

, 2012
Background: Insects respond to the spatial and temporal dynamics of a pheromone plume, which implies not only a strong response to"odor on", but also to"odor off". This requires mechanisms geared toward a fast signal termination.
