Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

Insect Molecular Biology, Volume 35, Issue 5, Page 556-575, October 2026.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

The Controlled Release of Insect Pheromones From Biobased Thermoplastic Compounds for Sustainable Pest Management

Advanced Sustainable Systems, Volume 10, Issue 9, September 2026.
This study advances sustainable pest management by characterizing novel insect‐specific pheromone compounds with a linear release profile. Release rate constants are derived from accelerated high‐temperature tests, enabling broadly applicable comparisons of pheromone‐polymer compounds.

Lessons to be popular: the chemical basis of aggregation in Trypanosoma cruzi-infected and non-infected Chagasic bugs

Royal Society Open Science
Aggregation is one of the most remarkable behaviours in the animal kingdom—a process that is usually governed by pheromones. Triatomines are blood-sucking bugs that act as vectors of Trypanosoma cruzi, the etiological agent of Chagas disease in mammals ...

Chemical cues mediating aphid location by natural enemies

European Journal of Entomology, 2008
There is increasing evidence that chemical cues play a pivotal role in host selection by the natural enemies of aphids. We use Vinson's (1976) division of the host selection process into habitat location, host location and host acceptance for both ...

The role of semiochemicals in the avoidance of the seven-spot ladybird, Coccinella septempunctata , by the aphid parasitoid, Aphidius ervi

, 2004
The role of semiochemicals in mediating intraguild interactions between the seven-spot ladybird, Coccinella septempunctata, and the aphid parasitoid, Aphidius ervi, was investigated. Female parasitoids avoided leaves visited by C.

Testing the behaviour of Australian brushtail possums (Trichosurus vulpecula) to candidate semiochemicals from conspecifics’ urine

, 2017
The Australian brushtail possum (Trichosurus vulpecula) is a prolific introduced mammalian pest. Current pest control methods involve traps and poisons, but are proving to be ineffective long term solutions.

Decoding chemical profiles in insect‐induced gall development: Insights from Phacopteron lentiginosum–Garuga pinnata interactions

Entomological Science, Volume 29, Issue 3, September 2026.
Analysis of volatile and non‐volatile metabolites across three developmental stages (3rd, 4th and 5th instar nymphal stages) of leaf galls induced by Phacopteron lentiginosum on Garuga pinnata revealed that the 3rd stage exhibited the highest chemical diversity and concentration followed by 4th and 5th stages.
