Abstract

Neonate codling moth larvae, Cydia pomonella (L.) responded positively to the odor of immature apples in an enclosed arena bioassay, in a Y-tube olfactometer, and in a straight tube olfactometer. In the arena bioassay, larvae contacted paper strips treated with apple odor. In the Y-tube olfactometer, larvae moved upwind and into the olfactometer arm carrying apple odor. In the straight tube olfactometer, larvae moved farther upwind per unit time in response to apple odor. Larval orientation to apple odor appeared to involve both an increase in forward speed (orthokinesis) and turning into airflow with increased odor concentrations (chemotaxis).
