Methodology for evaluation of pest resistance to zoocides by biological methods and antiresistance staregies
 Kocourek, František ; Stará, Jitka ; Zichová, Tereza ; Hubert, Jan ; Nesvorná, Marta
The methodology contains description of biological methods for evaluation of pest resistance to zoocides arranged according to world standards. The methods are verified on case studies on pests with proved resistance to insecticides or with high risk of selection of resistance in Czechia, as pollen beetle, Colorado potato beetle, cabbage seedpod weevil, cabbage stem flea beetle and codling moth. The methodology contains survey of basic principles of insect resistance management and proposals of antiresistant strategies for pest mentioned in the case studies. The methods for evaluation of resistance are utilized for resistance monitoring performed by state administration or other organisations. Recommendations given in antiresistant strategies are utilized for pest management in winter rape, potatoes and apples.

Certified technological procedure of laboratory tests of acaricidal compounds against stored product mites
 Hubert, Jan ; Nesvorná, Marta ; Stará, Jitka
The certified technological procedure was developed in order to support Czech national legislation - Act No. 258/2000. The procedure is aimed at the protection of stored plant substrates against infestation of mites (Acari: Astigmata). The procedure includes two tested methods (i) impregnated filter paper test and (ii) population growth tests. The procedure includes novel findings describing the discrimination doses of acaricidal compounds to the mites. The doses are useful for identification of resistance. The described methods enable the comparison of efficacy of different acaricidal compounds as well as the comparison of toxic effect to various populations of mites.
