INVESTIGATION OF THE EFFECT OF LIQUID SOAP AND GRANULOUS VIRUS (BACULOVIRUS LASPEYRESIA) ON THE INSECTICIDE EFFECTIVENES OF TOTAL PLANT EXTRACTS, TOWARD LASPEYRSIA POMONELLA L (LEPIDOPTERA; TORTRICIDAE) UNDER LABORATORY CONDITIONS

摘要

effect of liquid soap and granulous virus on codling moth (Baculovirus Laspeyresia) has been studied under laboratory conditions, on the insecticide efficiency of total plant extracts, toward codling moth (Laspeyresia pomonella L; Lepidoptera, Tortricidae). The best results - 100% of mortality with first instar caterpillars of codling moth (Laspeyresia pomonella L) can be obtained following the use of operating solutions made of mixtures containing a total extract of tobacco (Nicotiana tabacum L) orwhite hellebore (Veratrum album L), liquid soap (up to 0.2%), granulous virus on codling moth (Baculovirus Laspeyresia), having a titre of 10~9 granules/ml (up to 5%). The addition of liquid soap"Medics"~R-lemon increases the insecticide efficiencyby 23% compared to the applied extract without soap addition, against the first instar caterpillars of the pest.
