Lacewing larvae (Chrysoperla rufilabris), used for biological control of insect pests, are typically released by hand for treatment of small-scale ornamental and fruit crops. This study investigated the potential for mechanical release of larvae. Second instar larvae were mixed into vermiculite and rice hull carriers and subjected to vibrational and rotational motion. The number of live, mobile larvae reclaimed from the treated material was determined. While the mechanical treatments did not significantly reduce the number of mobile larvae recovered, rotation resulted in slightly greater larval damage than vibration.
