A Chemosensory Protein Detects Antifeedant in Locust (Locusta migratoria)
Insects, 2020 Chemosensory system is vitally important for animals to select food. Antifeedants that herbivores encounter can interfere with feeding behavior and exert physiological effects.

Pest Management Science, EarlyView.Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...

Antifeedant Activity of Spin-Labeled Derivatives of Deoxypodophyllotoxin against Larvae
Natural Product Communications, 2013 To continue our search for natural product-based compounds for the control of Brontispa longissima larvae, eight spin-labeled podophyllotoxin derivatives (4a-h) and the intermediates 2 and 3 were tested for their insect antifeedant activity against third-

Pest Management Science, EarlyView.Extended bioassays revealed that azadirachtin and spirotetramat show strong delayed effects against Phthorimaea absoluta, underestimated by the standard Insecticide Resistance Action Committee (IRAC) method 022 protocol. Incorporating long‐term exposures is essential to accurately assess slow‐acting insecticides and improve resistance management ...

Guaianolides from the Aerial Parts of
Natural Product Communications, 2006 Seven guaianolides were isolated from the acetone extract of the aerial parts of Centaurea hololeuca Boiss. The antifeedant activity of the natural compounds (1–7) and of four chloro derivatives (8–11), synthesized from repin (1) and janerin (3) were ...

Antifeedant Activity of Some Polygodial Derivatives
Zeitschrift für Naturforschung C, 2008 Polygodial (1) and its derivatives acetal 2 (propylene) and 3 (ethylene) were prepared and their antifeedant activity and toxic effects evaluated on several insect species with different feeding ecologies (Spodoptera littoralis, Leptinotarsa decemlineata, Myzus persicae and Rhopalosiphum padi) along with that of polygonone (4).
