The use of a suction trap for monitoring flight activity of cereal aphids (Homoptera: Aphidinea: Aphididae)


, : The use of a suction trap for monitoring flight activity of cereal aphids (Homoptera: Aphidinea: Aphididae). Entomologia Generalis 16(2): 161-166

A suction trap at a height of 12.2 m above the ground was used to monitor aphids at Aschersleben, Germany, in 1985-90. The results were compared with those for a yellow tray. Of the cereal aphids, Rhopalosiphum maidis and Sitobion avenae were much more abundant in the suction trap than in the yellow tray, while the number of examples of Metopolophium dirhodum was mostly no higher than in the yellow trap.

Naturally occurring beta-carbolines are lipophilic compounds which show psychotropic and physiological effects in mammals. They bind to distinct high-affinity binding sites in various mammalian tissues. However, the mechanism by which the beta-car...
