Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, and pathogens. They can be an important component of integrated pest management (IPM) programs. Family Chamaemyiidae (Diptera) are small silver flies, distributed worldwide. The larvae are predators of plant’s aphids and similar insect pests. The observation of silver flies were made during 2010-2012, on tobacco plants in the area of Prilep, with application of the following methods of catching: check on all leaves of 20 tobacco stalks and check of 100 tobacco leaves (Davies method). The collected material was further nourished, cultivated and analysed under laboratory conditions. Factors that are optimal for tobacco plant development (temperature, precipitations and insolation) are also favorable for development of aphids. M. persicae develop the number colonies on tobacco leaves, also on flower and seed capsules. Common feature is that silver flies follow the development of the leaf aphids and greatest quantitative representations of silver flies are noticed in August. During investigations we determined one aphidophagous species Leucopis sp., as an predator of green peach aphid Myzus persicae Sulzer on tobacco. Leucopis sp. survival on M. persicae and quantitative representation was significantly higher during the 2011-2012 than 2010. Their abundance is highly correlated with aphid density.Our research and climate monitoring data can be used for making prediction models for biological control of insects that can be useful for plant protection. Leucopis sp. may be successfully used for the classical biological control of living within a high density aphid colony.
