The application of an experimental sample of the preparation lecanicil based on the fungusLecanicillium lecanii strain BL-1, in a 1 % concentration in the beginning of berry coloring againstthe honeythuckle-cereal aphid caused a pest number decrease on the 7 th day after treatment of41.8% (Table 3).ConclusionsIt was determined that the main pests both by occurrence and number in honeythuckle plantationsin Belarus are the honeythuckle-cereal aphid - Rhopalomyzus lonicerae Siebold, the rose tortrixmoth - Archips rosana L. and the bud moth - Spilonota ocellana Den. et Schiff. Considerably lessdamage is caused by – the red spider mite - Tetranychus urticae Koch. and the European fruitlecanium - Parthеnolecanium corni corni Bouch.It was revealed, that cv ‘Lakomka’ in the conditions of Belarus is not damaged by thehoneythuckle-cereal aphid and to a lesser degree, in comparison with the cultivars ‘Vasilievskaya’and ‘Goluboe vereteno’ is colonized by rose tortrix moth, the European fruit lecanium and the redspider mite.The biological preparation baciturine, ps., titer 45 – 60 mlrd viable spores g -1 (spore-ctystalcomplex and the exotoxin Bacillus thuringiensis, var. darmstadiensis, strain № 24 – 91) at the rateof preparation application 6 l hа -1 and at the working solution rate of 600 l hа -1 has caused 41.6 %death rate of rose tortrix moth caterpillars on the 3 rd day after treatment and 55 % - on the 7 th dayafter preparation application. The efficiency of application of an experimental sample of thepreparation lecanicil produced based on the fungus Lecanicillium (Verticillium) lecanii Zimm.Zare et W. Gams strain BL-1. 6 l hа -1 at the beginning of berry coloring against honeythucklecerealaphid was 41.8 % effective on the 7 th day after treatment.References1.
