| Summary: | A method for succesive rearing of the common green lacewing, Chrysoperla carnea Stephens, on adult food consisting of milk, eggs, fruit, sugar, yeast in the form of small grains and wheat germ stuffing 'Kalčko' was established. For the first time the common green lacewing, Chrysoperla carnea Stephens, was reared in this way on improved artificial food described in the study, which contains wheat germ stuffing 'Kalčko'. Larvae were reared on green peach aphid, Myzus persicae Sulz. A test of the efficiency of Chrysoperla carnea of the green peach aphid on hydroponically grown peppers was done. Reproduction of the common lacewing, Chrysoperla carnea Stephens, was successful under laboratory conditions. The artificial diet specially prepared for the purpose had a favourable effect on the fecundity of females. The larvae developed well when they were fed on the green peach aphid, Myzus persicae Sulz. Because an abundant supply of aphids was provided and additional obstacles were used so that the larvae did not find one another, cannibalism was reduced. Natural mortality of subjects during reproduction time was moderate. The application of eggs of Chrysoperla carnea attached to cotton gauze is an appropriate method for target introduction into greenhouses on a smaller scale.
