Face or flee? Fenitrothion resistance and behavioral response in populations of the maize weevil, Sitophilus zeamais

, 2011
Insect survival in the presence of contact insecticides may be through physiological mechanisms or avoidance of contact with the compound. Curiously, although the first alternative is the object of frequent attention, the second is often neglected, but ...

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Seasonal Effect on the Chemical Composition of Lippia alba Volatile Chemotypes

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
L. alba, a Brazilian medicinal species, is known for its volatile chemotypes, with fewer studies of its nonvolatile composition. Chemical characterization via GC‐MS and LC‐MS of five individuals, during the rainy and dry season, confirm the variability of the volatile composition but the nonvolatile composition was similar, with a discrete seasonal ...
