Abstract
U radu je prikazan insekticidni utjecaj dijatomejske zemlje, prašiva i ekstrakta carske paulovnije na kestenjastog brašnara. U tretmanima je primijenjeno prašivo lista carske paulovnije, dijatomejska zemlja Celatom Mn-51® i SilicoSec® te vodeni ekstrakt carske paulovnije, kombinacija vodenog i alkoholnog ekstrakta carske paulovnije u omjeru 1:1 i alkoholni ekstrakt (2-propanol) carske paulovnije u različitim dozama, a mortalitet je očitavan nakon 7. i 14. dana ekspozicije. Učinkovitost svih tretmana ovisila je o dozi i ekspoziciji, povećanjem doze i produljenjem ekspozicije povećavao se i mortalitet. Najučinkovitijim su se pokazala inertna prašiva gdje je dijatomejska zemlja SilicoSec® pokazala bolji rezultat pri najvišoj dozi 81,25 % u usporedbi s dijatomejskom zemljom Celatom Mn-51®. Zadovoljavajući mortalitet postignut je kod alkoholnog ekstrakta (2-propanol) carske paulovnije 61,2 %, dok kod vodenog ekstrakta i kombinacije vodenog i alkoholnog ekstrakta carske paulovnije u omjeru 1:1, nije postignut značajan mortalitet. Prašivo carske paulovnije pokazalo se najmanje učinkovitim, a samo pri najvišoj dozi i pri najduljoj ekspoziciji (14 dana) postignut je statistički značajno viši mortalitet.
Abstract (english)
This paper presents the insecticidal effect of diatomaceous earth, dusts and extract of the empress tree against red flour beetle. Treatments were applied with the empress tree leaf dusts, diatomaceous earths Celatom Mn-51® and SilicoSec®, aqueous extract, a combination of the aqueous and alcoholic extract of the empress tree in 1:1 ratio and the alcoholic extract (2-propanol) of the empress tree in different doses, with mortality observed after 7 and 14 days of exposure. The efficacy of all treatments depended on the dose and exposure, with mortality increasing with increased dose and prolonged exposure. Inert dusts proved to be the most effective, with diatomaceous earth SilicoSec® achieving a better result of 81.25 % at the highest applied dose level compared to diatomaceous earth Celatom Mn-51®. Satisfactory mortality (61,2 %) was observed with alcoholic extract (2-propanol) of empress tree, as opposed to the aqueous extract and the combination of aqueous and alcoholic extract of empress tree in 1:1 ratio where no significant mortality was observed. Powder of the empress tree proved to be the least effective, with statistically significant higher mortality revealed at the highest dose and at the longest exposure level (14 days).
