PREPARATIVE FORM OF PHEROMONE FOR STRUGGLE AGAINST FLOUR MOTH IN MILLING PLANT AND BAKERY

摘要

FIELD: agriculture. SUBSTANCE: preparative form of pheromone (a preparation "Kunemone-D") is obtained on the basis of 9Z,12E-tetradecadiene-1-yl-acetate that is a sexual hormone of flour moth. Preparative form is pieces (diameter is about 3 mm, wall thickness is about 0.5 mm, length is 10 mm) made of polymeric material. Their core is a bundle of Dacron threads (thickness is 0.001-0.1 mm) containing an adsorbed pheromone at amount 0.2-1.0 mg per a piece. Each piece is covered with polyvinyl chloride layer that is applied from cyclohexane as a solvent followed by solvent evaporation. Preparative form is used for trap of insect-pests to decrease their population. EFFECT: simplified method of preparing, enhanced effectiveness for a long time. 2 tbl, 3 ex
