Kasianov A. Pests of oilseed rape, and measures to restrict their numbers in the Right-Bank Forest-Steppe of Ukraine

The objects of research - a harmfulness and biological characteristics of the cabbage flea beetles, beetle rape, cabbage aphid, cabbage seed pod weevil. An aim of researches is improving the environment - oriented security of oilseed rape to major pests in the Right-Bank Forest-Steppe of Ukraine taking into account soil and climatic conditions and crop management technologies. Scientific novelty is: in the Right-Bank Forest-Steppe of Ukraine in modern conditions studied and refined features of the seasonal dynamics of the crucifer flea beetles, beetle rapeseed and cabbage aphid in the agricultural lands of spring and winter oilseed rape during the growing season. First studied by developmental and environmental cabbage seed pod weevil. Clarified the species composition of these pests in the agricultural lands of rape. The influence of some agro-technical measures (crop rotation and hunting cultures) on the population density of the crucifer flea beetles and beetle rape. It was established technical efficiency of new insecticides at the pre-treatment of seeds against crucifer flea beetles and spraying of crops against rape pollen beetle and cabbage aphids.
