摘要：

Six gramineous plant species, including cereal crops, were used as food for the ladybird beetle Cynegetis impunctata in a laboratory experiment. Five of them, including wheat and barley, were suitable for larval development, while Phalaris arundinacea L. was unsuitable as food. Larval development lasted 20-23 days. Females reared on leaves of wheat and Agropyron repens L. laid on average 153-182 eggs. Larvae and adults did not exhibit a preference to wild gramineous plants compared to cultivated cereal crops. Although wheat and barley represented suitable food for C. impunctata, this species is not a potential pest for these crops. This ladybird is wingless, has limited dispersion abilities and is vulnerable to agrotechnical cultivations that may destroy dormant adults in agricultural plots.
