CROP PROTECTION, 9(1), 65–72.

By: R. Meagher n & . Meyer n

INFLUENCE OF TRAP COLOR AND SAN JOSE SCALE (HOMOPTERA, DIASPIDIDAE) PHEROMONE ON STICKY TRAP CATCHES OF 10 APHELINID PARASITOIDS (HYMENOPTERA)

ENVIRONMENTAL ENTOMOLOGY, 19(4), 926–931.

By: D. Mcclain n, G. Rock n & J. Woolley n

TL;DR: In comparisons with colored traps baited with pheromone, black traps attracted significantly more E. perniciosi than did yellow or white traps in the unsprayed apple orchard in 1987, which suggests an interaction between olfactory and visual cues in host location by this species.
