TRAPPING CRYPTOPHLEBIA-ILLEPIDA AND C-OMBRODELTA (LEPIDOPTERA, TORTRICIDAE) IN MACADAMIA IN HAWAII

Two species of Cryptophlebia found in Hawaii's macadamia orchards are active in different parts of a tree canopy. C. illepida (Butler) males were mostly caught in traps hung 1.5 m to 9.1 m from the ground; whereas C. ombrodelta (Lower) males were caught from 9.1 m to 15.2 m. A plastic, cylindrical sticky trap caught equal numbers of C. illepida males as Pherocon 1C traps but more than delta traps. A synthetic pheromone blend of 93% (Z)-8-dodecenyl acetate, 4% (E)-8-dodecenyl acetate, 1% (Z)-8-dodecenol, and 2% (Z)-7-dedecenyl acetate attracted more males than other blends. No significant differences were detected between the two Cryptophlebia species in their response to the four-component pheromone blend when traps were hung 4.6 m from the ground.
