Development and testing of dispensers with aggregating pheromone and attractant to increase the capture of Western flower thrips with sticky traps

Abstract
Methyl nicotinate and its analogues are effective attractants for various thrips species, including Western fl wer thrips. These compounds are highly volatile; therefore, for the convenience of their practical use as attractants in traps, it is necessary to ensure their prolonged evaporation. The article presents the materials of laboratory studies of the evaporation of methyl nicotinate from dispensers of various designs. The best option turned out to be 2 x 2.5 cm plates hermetically sealed in double bags of high-density polyethylene 200 microns thick. This version of the dispenser with an attractant (methyl nicotinate, 150 mg) and an aggregation pheromone (neryl-2-methylbutanoate, 1 mg) applied to it, manufactured at the VNIIKR, was tested for efficiency when catching the Western fl wer thrips Frankliniella oc cidentalis on a cucumber culture in conditions of closed ground with colored sticky traps “Plate”. The traps with the developed dispensers caught 1.4–1.9 times more thrips compared to the control ones for 40 days. After 40 days, experimental and control traps caught insect pests in approximately the same way, which indicated the exhaustion of the dispenser resource.
