METHOD OF PURPOSIVE SELECTION OF HIGH VIABLE TRICHOGRAMMA POPULATIONS

摘要

A method of purposive selection of high viable Trichogramma populations includes gathering thereof from the natural environment. For attracting, infecting and following selection of the Trichogramma just laid eggs of the oaken silkworm moth, preliminary glued onto slips of hard paper, which are disposed in virgin natural shrubby or tree landmarks, are used. For attracting and keeping the Trichogramma, mangers filled with a 5% honey aqueous solution in a mixture with a modified ribonucleic acid (RNA) precursor, in particular methyluracil, in concentration of 0.035-0.008% are arranged close to the slips.
