Abstract

The use of natural enemies is the basic means of biological control of arthropods, vertebrates, weeds and plant pathogens. Chamaemyiidae, also known as silver flies or silver aphids, are larval predators of Homoptera found in a wide range of cultural plants, trees and weeds. Observation of silver flies was made during 2010-2012 in the region of Prilep, on 20 tobacco stalks and 100 tobacco leaves. The collected material was further analysed under laboratory conditions. During the investigations, the aphidophagous species Leucopis sp. (Chamaemyiidae) was determined as predator of Myzus persicae Sulz. on tobacco. Females lay their eggs singly on the underside of tobacco leaves, among the aphid colonies. The larva of this species is considerably greedier during the second, and particularly during the third larval stage. Larvae are transformed into pupae in the same plants on which they feed. Adults are mobile and they are able to locate the prey quickly. Leucopis sp. survival on M. persicae and its quantitative representation was significantly higher in 2011-2012 than 2010. The most massive occurrence of silver flies is recorded in August. Chamaemyiidae can be used in biological control of aphids, as a part of integrated protection against these pests.
