Název v původním jazyce

Improvement of vacuum effect on mortality of Sitophilus granarius (Curculionidae) using oxygen chemical absorber in laboratory conditions

Popis výsledku v původním jazyce

The aim of this preliminary study was to find out if oxygen absorber can improve the efficacy of vacuum on mortality of stored product pests. The effect of vacuum (V) and vacuum in combination with the chemical absorber ATCO 400 (VA) on mortality of S. granarius adults was compared in dependence on temperature (15oC, 25oC), exposition time (1-7 days) and vacuum value (1.5 kPa). The airtight bags were used for laboratory experiments. Each bag contained a plastic vial with 50 beetles (age 1-2 weeks) without grain substrate. The vials were closed with permeable caps. Seven replicates were used for each treatment. Bags were sealed using vacuum packing machine (KOMET Vacuboy). The results showed significant differences in efficacy of both V and V+A in dependence on temperature. Lethal time was 74 (LT50) and 160 h (LT99) of exposure in vacuum at 25oC. Low temperature (15oC) significantly prolonged the exposition time necessary for mortality of tested beetles in constant value of low pressure
