Pheromone Monitoring in the Granaries of Uzbekistan
Abstract
The pheromonitoring of pest insects population was carried out in the granary conditions. The results of pheromonitoring let us detect the pest insect’s location at lowest abundance, while visual inspections are not effective, and to determine the data of effective location in granary, proportions traps and pheromone preparative dose. The aggregation pheromone of the synthetic analogue Sitophilus weevils had been carried out, according to the general procedure for preparation of aldol product. Especially for increasing attractiveness of pheromone traps, different types of food baits were tested. The results were observed with using of germinated wheat grains moisten by wheat germ oil. The corn oil was more attractive and effective for attractiveness of whole pest insects in granary. The wheat germ oil and burdock oil was preferred, as food bait, especially for weevils. The special perforated construction of the pheromone trap for pest insects usage has been developed and recommended for storage areas. In a condition of granary, successful testing of pheromone monitoring makes it possible to establish the timing and necessity of quantitative chemical treatments.
