The Eurasian woodwasp, Sirex noctilio, is an invasive pest of pines in temperate regions the Southern Hemisphere, and has been introduced to North America. A parasitoid, Ibalia leucospoides, broadly employed for biological control this pest. Volatiles emitted from fungal symbiont S. Amylostereum areolatum, are reliable cues noctilio I. leucospoides females optimize their foraging behavior (host...

Producers in the Western Cape province of South Africa are looking towards a push-pull strategy to reduce oviposition damage plums by western flower thrips (WFT). White clover, Trifolium repens L., favoured host plant WFT, was investigated as possible trap crop provide “pull” element. The attractiveness collected volatiles white clover flowers and unopened (balloon stage) open plum (Prunus sali...

Xylella fastidiosa, the causal agent of several diseases in crops economic interest, could be rapidly transmitted and spread throughout agroecosystem landscape by xylem sap-feeding insects. Chemical signals environment drive behaviour Attractive or repulsive responses to may affect insects’ fitness, survival reproduction, elicit different movement patterns. Specific patterns derived from olfact...

Abstract Oleogels have been widely studied as delivery matrices for lipophilic compounds. Despite their potential, oleogels are underexplored the formulation and release of semiochemicals insect behavior manipulation strategies. An ethylcellulose‐candelilla wax‐oleogel a suitable carrier slow volatile semiochemicals, employing sesquiterpene β ‐caryophyllene model substance is presented. A curre...

In this study, the orientation of two different predator species [(Coccinella septempunctata L., Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae)) to aphids [Aphis fabae Scopoli and Acyrthosiphon pisum Harris (Hemiptera: Aphididae)] was investigated. Y-type olfactometer which made glass material with one entrance exit openings used in study. Different applications were applied ends pred...
