Experimental design for non-choice (A) and feeding choice (B) assays of Lymantria dispar. Schematic presentation of experimental setup where 10 larvae were introduced under glass cylinder: branches of Prunus cerasifolia with 10 leaves (3) were put into flasks with water (2) and then held in the pots (1) with sand (5) covered with filter paper on the top (4); leaf mass was treated by spraying with test solutions, and after the drying of deposit, glass cylinders (6) covered with cheesecloth (8) fixed with rubber (7) were put for isolation of the treatment. In the no-choice feeding assay, a branch was treated with tested solutions (A), while in the choice feeding assay, one branch was treated with tested solutions and another remained untreated (B).
