Results of the use of chrysopids


, : Results of the use of chrysopids. Rastitelna Zashchita 25(3): 14-16

Various species of chrysopids afford control of insect and mite pests in Bulgaria, and an account is given of an attempt there to rear the common one, Chrysopa carnea Steph., on Myzus persicae (Sulz.) on tobacco in the laboratory for release according to a Russian technique. Fair success had been obtained by 1975, and seasonal field releases of second-instar larvae on tobacco were therefore made. Excellent control of the aphid was obtained in a short time.
