Abstract
Dynamics of the main pests of cucumber over a five-year period were analysed. The impact of meteorological conditions on the pest dynamics was observed when growing photo culture cucumbers in a greenhouse all year round. The possibility of successful and efficient use of cotton aphid, spider mite, tobacco thrips, greenhouse whitefly and noctuid moth entomophagous was demonstrated. Application rates for several entomophagous were proposed for prevention and protection of cucumber plants against the above-mentioned pests.
Highlights
There is a long list of natural enemies that could be used for biocontrol of pests on cucumber indoors
Seedlings are treated with mites A. swirskii and N. cucumeris against thrips and greenhouse whitefly
Apart from mites, application of predatory bug M. pygmaeus is recommended for protection of cucumber plants against greenhouse whitefly
Summary
There is a long list of natural enemies that could be used for biocontrol of pests on cucumber indoors. Other factors have the considered impact such as cultivated plants, structure and volume of the greenhouses floor area, usage of new technologies of plant growth, and the unique phytosanitary history, which every greenhouse has. In Russia, the indoor floor area is growing, mostly because of the modern industrial greenhouses in which new plant growth technologies are widely used. In the North-West region, there is one of the leaders between greenhouse facilities - “Year around” on which base our institute has been conducted the assessment of BCA efficacy during the last five years.
