Methodology for evaluation of resistance of pollen beetle to insecticides
 Stará, Jitka ; Falta, Vladan ; Kocourek, František
The methodology of evaluation of pollen beetle resistance to insecticides includes approaches that enable easy and reliably to detect resistance to pyrethroids and organophosphates. The methodology includes also information about mechanisms of resistance of insects to insectidies and methods, how to evaluate the resistance. To prevent or slow-down development of resistance in pollen beetle, antiresistant strategies are proposed.

Certified technological procedure: antiresistant strategy for standard and spot phosphine fumigation of beetles infesting stored grain
 Aulický, Radek ; Stejskal, Václav
Currently there is growing evidence on failures of many pesticides on stored product pests including toxic insecticide fumigants. The increasing resistance is frequently a result of suboptimal use in terms of good agricultural and technological practice during fumigations. The technological procedure contains set of practical instructions on PH3 treatment of grain stored in flat grain stores leading to decrease of risk of resistance evolution. Notably, the technological procedure contains new and original information and risk evaluation on PH3 “spot. fumigation” of grain i flats stores; It shows the spatial zone of efficacy and limits for usage of this method.
