Certified methodology for rapid evaluation of the current level of resistance of stored product infesting pests to phosphine gas based fumigants: Methodology for DDD, agriculture and food industry workers
Aulický, Radek ; Stejskal, Václav ; Frýdová, Barbora
The presented new methodology is a set of information and procedures for evaluation of the sensitivity/resistance of storage pests to the phosphine (PH3) which is plant protections and/or biocide active substance commonly used for fumigation of infested commodities and empty store spaces as a key pest control intervention. The procedure is based on the international tests Phosphine Resistance Test Kit (Detia DEGESH's) and on the originally scientifically developed findings and information. The regular assessment of the resistance or resistance of field populations is one of the pillars of IPM whose implementation into practice helps to reduce the consumption of chemical products.

Certified method for evaluation of biological efficacy of controlled atmospheres and fumigation in silos using biotest kits: methodology for workers in DDD, agriculture and food industry
Aulický, Radek ; Stejskal, Václav ; Plachý, Jan
Evaluation of the efficacy of controlled atmosphere or insecticide fumigation treatment of stored commodities is very difficult when these materials are located in silo bins. The main difficulty is to take measurements and samples within the entire commodity (vertical-silo) profile. Until now, there are no standard procedures and tools that would allow the evaluation of efficacy of controlled atmospheres under such situations. These methodical deficiencies are some of the main reasons why t controlled atmosphere methods are not commonly used in practice, although they are – under many conditions - relatively cost-effective disinfection measures. This methodology is the first Czech set of procedures for the proper preparation, application and evaluation of bioassays that can be used for evaluation of the efficacy of controlled atmospheres and fumigation in silo bins cells. The methodology also shows some practical examples and experimental results on how to use bioassay. The certified methodology was prepared with the financial support of the NAZV agency and is the technological an scientific output of the project QJ1310057.

Application of gel baits for control of pest cockroaches
Aulický, Radek ; Stejskal, Václav
The certified technological procedure was developed in order to support Czech national legislation 258/2000. The procedure is aimed at the control of pest cockroaches in agricultural and food industry premises using insecticide gel baits. The technological procedure contains new and original information on gel bait efficacy and instructions on their application under various environmental circumstances.

Low-labour demanding technological procedure of monitoring of stored product beetles using traps with multi-component attractant
Stejskal, Václav ; Aulický, Radek
The aim of the work was to provide pest control, agricultural and food industry practice with information about multi-component monitoring tool for stored product pest beetles. It was evaluated the laboratory efficacy of a new trap „Multi-Insect-Trap“, containing combined pheromone and food attractant for several storage pests species. In small arenas (exposure: 74 hours, 25oC) was tested 6 species of stored product beetles. The efficacy decreased in the following order: Cryptolestes ferrugineus – 100%, Lasioderma serricorne – 100%, Oryzaephilus surinamensis - 70%, Stegobium paniceum - 70%, Sitophilus granarius – 60% and Tribolium castaneum- 40%. The work was supported by projects of Czech ministry of agriculture NAZV QH91146 and Vyzkumný zamer 0002700604.

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.
