Abstract:Mite mortality in two apiaries, one with 32 and the other with 15 honeybee (Apis mellifera carnica) colonies, was recorded prior to and after flumethrin or fluvalinate treatments and after a control, oxalic-acid application. During the 42- and 51-day pre-treatment periods, the average daily natural mite drop was 0.04 (± 0.04) and 2.82 (± 2.19), respectively, which represents 1.09% (± 1.06) and 3.84% (± 3.04) of the total number of mites found during the experiment. The flumethrin or fluvalinate applications resulted in an average mite mortality at the two apiaries of 214.46 (± 260.02) and 4,098.64 (± 2,508.31). The treatments resulted in a 19.11% (± 14.62) and a 39.28% (± 10.47) reduction in the number of mites in slightly infested colonies and 94.30% (± 4.26) and 96.24% (± 3.14) in highly infested colonies. The difference in treatment efficacy between both apiaries was significant (P < 0.001) and indicates that fluvalinate and flumethrin are highly efficacious in dealing with highly infested honeybee colonies with sealed brood. The importance of effective mite control in colonies with a high level of natural mite mortality is discussed in this study.

Title:Likvidace Varroa destructor ve včelstvech včely medonosné pomocí Flumetrinu nebo Fluvalinátu
Abstract:Ve dvou včelínech, s 32 a s 15 včelstvy (Apis mellifera carnica), byla sledována mortalita roztoče před a po ošetření flumetrinem nebo fluvalinátem a po kontrolní aplikaci kyseliny šťavelové. Během doby před ošetřením (42 a 51 dní) byl průměrny přirozený spad roztočů 0,04 (± 0,04) a 2,82 (± 2,19), což bylo 1,09 % (± 1,06) a 3,84 % (± 3,04) z celkového počtu roztočů zachycených během experimentu. Po aplikaci flumetrinu nebo fluvalinátu ve dvou včelínech byla průměrná mortalita roztočů 214,46 (± 260,02) a 4 098,64 (± 2 508,31). Ošetření vedlo ke snížení počtu roztočů o 19,11 % (± 14,62) a 39,28 % (± 10,47) u lehce napadených včelstev a o 94,30 % (± 4,26) a 96,24 % (± 3,14) u silně napadených včelstev. Rozdíl v účinnosti ošetření mezi oběma včelíny byl statisticky významný (P < 0,001) a ukázalo se, že fluvalinát a flumetrin jsou vysoce účinné v boji se silně napadenými včelstvy se zavíčkovaným plodem. V této studii je pojednáno o významu/důležitosti efektivní kontroly roztočů ve včelstvech s jejich vysokou přirozenou mortalitou.
