We decided to present the use of different inert dusts as a way of controlling the aforementioned pest. We focused on the categorization of powders, the presentation of individual groups of inert dusts and the description of one or more substances belonging to a specific group. In addition to a general presentation and the mode of action of specific inert dusts, we also provided practical examples that show whether the agent/substance has already been used against the Colorado potato beetle. With the aforementioned, we also tried to sum-marize whether the described substance has the potential to be used in practice or not. We would also like to point out that wood ash and diatomaceous earth are the most promising in-ert dusts against L. decemlineata. Wood ash is effective against larvae and to a lesser extent also against adults. Diatomaceous earth is also effective in reducing the number of pests on po-tato plants. Other inert dusts mentioned in scientific literature are probably less effective or have not even been tested or used against this pest yet. Further research, both under laboratory conditions and outdoors, are necessary to definitively deter-mine the effectiveness of this selected inert dustsV preglednem članku se osredotočamo na al-ternativni pristop varstva krompirja (Solanum tuberosum) pred koloradskim hroščem (Leptinotarsa decemlineata), ki pri nas in v svetu velja za najpomembnejšega škodljivca te pomembne poljščine. V prispevku predstavljamo uporabo različnih inert-nih prahov za zatiranje tega škodljivca. Osredotočili smo se na kategorizacijo prahov, predstavitev posameznih skupin inertnih prahov in opis ene ali več snovi, ki pripadajo specifični skupini. Poleg splošne predstavitve načinov delovanja posameznih pra-šiv navajamo tudi praktične zglede uporabe prašiv proti kolo-radskemu hrošču, s čimer želimo predstaviti potencial različnih prašiv za uporabo v praksi. Ugotavljamo, da veljata lesni pepel in diatomejska zemlja za bolj perspektivna inertna prahova pri zatiranju škodljivih žuželk. Lesni pepel učinkovito deluje proti ličinkam ter v manjši meri tudi na odrasle osebke, diatomejska zemlja pa prav tako vpliva na zmanjšanje številčnosti kolorad-skega hrošča na krompirju. Ostala inertna prašiva so v strokov-ni literaturi izpostavljena kot manj učinkovita oz. sploh še niso bila preizkušena ali uporabljena proti temu škodljivcu. Za do-končno določitev učinkovitosti prašiv bodo potrebne nadaljnje raziskave, tako v laboratorijskih razmerah kot na prostemTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Biotehniška fakulteta
