Genistein and Aphid Probing Behavior: Case Studies on Polyphagous Aphid Species.

(1) Background: Genistein is a naturally occurring flavonoid with a rich spectrum of biological activities, including plant-herbivore interactions. The aim of the study was to evaluate the effect of exogenous application of genistein on aphid behavior during probing in plant tissues. (2) Methods: , ssp.

Antifeedant Potential of Geranylacetone and Nerylacetone and Their Epoxy-Derivatives against (Sulz.).

Geranylacetone and nerylacetone are natural sesquiterpenoids, which play various roles in plant-insect interactions, including the deterrent and repellent effects on herbivores. The structural modifications of natural compounds often change their biological activities. The aim of the study was to evaluate the effect of geranylacetone, nerylacetone and their epoxy-derivatives on the probing and settling behavior of (Sulz.

Effect of Naringenin and Its Derivatives on the Probing Behavior of (Sulz.).

Substances that alter insect behavior have attracted a lot of attention as potential crop protection agents. Naringenin (5,7,4'-trihydroxyflavanone) is a naturally occurring bioactive flavanone. We evaluated the influence of naringenin on aphid activities during individual phases of probing and feeding and the effect of structural modifications of naringenin on its activity towards aphids.

New insight into the behaviour modifying activity of two natural sesquiterpenoids farnesol and nerolidol towards (Sulzer) (Homoptera: Aphididae).

The effect of structurally related sesquiterpenoids (E,E)-farnesol and cis-nerolidol on the host-plant selection behaviour of the peach potato aphid Myzus persicae (Sulz.) was evaluated using electrical penetration graph (EPG) technique. No repellent effects of (E,E)-farnesol and (Z)-nerolidol to M.

β-Thujone and Its Derivatives Modify the Probing Behavior of the Peach Potato Aphid.

Thujone is a natural biologically active monoterpene ketone component of essential oils of numerous plants. The aim of the study was to evaluate the effect of β-thujone and β-thujone derivatives bisulfite adduct, lactone, oxime, and lactam application on behavior of (Sulz.) (Hemiptera: Aphididae) during probing and settling.

Antixenosis Potential in Pulses Against the Pea Aphid (Hemiptera: Aphididae).

The aim of the study was to explore the acceptability of 14 species, varieties, and cultivars of grain legumes (Fabales: Fabaceae) to the pea aphid, by investigating the aphid probing behavior using the electrical penetration graph (EPG) technique. Phaseolus coccineus L. 'Felicia', Pisum sativum L.
