Tests on the rearing of Chrysopa carnea Steph. (Neuroptera, Chrysopidae) in a controlled environment



Tests on the rearing of Chrysopa carnea Steph. (Neuroptera, Chrysopidae) in a controlled environment



Bollettino dell' Istituto di Entomologia della Universita degli Studi di Bologna 32: 291-304



Chrysopa carnea Steph., a predator of aphids, coccids and mites, was reared in the laboratory in Bologna, Italy, under controlled conditions of 19-21 deg C, 65-85% R.H., LD 16:8 and a light intensity of 2400 lux. The adults were fed on 2 semi-synthetic diets based on yeast extracts, and the greatest fecundity (which was statistically significant) was obtained with the diet containing an extract of the yeast Saccharomyces fragilis, saccharose and water.
