Characteristics of biological preparations for apple protection from the main pests in the Western Forest-steppe of Ukraine

The modern bioinsecticides impact was researched on the main apple agrocenosis in Western Forest-steppe of Ukraine. It has been determined that the microbiological preparations efficiency against the apple aphid (Schizotetranychus pruni Oudms), against garden spider mite and against the godling moth (Laspeyresia pomonella L.). It has been established that the mixture of biological preparations Koloradocide, powder in norm 3 kg/ha, and Gaubsin, solution in norm 10 l/ha have shown the synergestic effect and high impact on phytophages.

Occurrence of entomopathogenic fungi in arable soil and meadow soil

The samples of soil for experiment were taken from arable field and meadow. Larvae of <i>Laspeyresia pomonella</i> and <i>Plodia interpuactella</i> were used as an "insect bait" for isolation of entomopathogenic fungi from the soil. <i>Beauveria bassiana, Metarhizium anisopliae, Paecilomyces farinosus</i> and <i>P. fumosoroseus</i> were isolated from both kinds of soil.
