Uporedna analiza dužine života imaga Plodia interpunctella (Hübner) odgajenih na tri vrste orašastih plodova

Abstract

Bakrenasti plamenac brašna (Plodia interpunctella, Lepidoptera, Pyralidae) predstavlja ekonomski najznačajniju štetočinu uskladištenih prehrambenih proizvoda. Cilj istraživanja bio je da se utvrdi da li postoje razlike u dužini života imaga P. interpunctella gajenog na izlomljenim jezgrama oraha, lešnika i badema. Najduži životni vek od 7,69 dana imala su imaga gajena na orahu. Na bademu i lešniku ova vrednost se statistički značajno ne razlikuje, i iznosi 7,07 i 6,73 dana, po podlogama. Na osnovu rezultata možemo zaključiti da je orah najpogodniji supstrat za razviće P. interpunctella.

Indian Meal Moth (Plodia interpunctella, Lepidoptera, Pyralidae) is one of the most important pests of stored food products. The aim of this study was to determine the influence of different nutrient medium (broken kernels of walnuts, hazelnuts and almonds) on life span of imago P. interpunctella. The longest life span (7,69 days) was recorded on walnut. On hazelnut and almond, this value was statistically not significantly different, amounting to 7,07 and 6,73 days, respectively. According to obtained results, it can be concluded that the walnut is the most suitable nutrient medium for the development P. interpunctella.
