The influence of food on eggs’ hatching of Plodia interpunctella (Hbn.) was valued; 24 substrates were tested. 100 eggs were placed on a first layer of product about 2-3mm thick and afterwards they were covered with a second layer of equal thickness. 4 replications were carried out for every product. In absence of food, the eggs show the highest average values for hatching (95±0,4). The lowest average values of hatching were observed on finely ground pine seeds (6±0,7) and on finely ground almonds (11,8±1,4), while those higher than 90 are observed for castor sugar, powdered cinnamon, dried yeast and powdered garlic.
E’ stata valutata l’influenza del substrato alimentare sulla schiusura delle uova di Plodia interpunctella (Hbn.); sono stati saggiati ventiquattro substrati. Cento uova sono state distribuite su un primo strato di prodotto dello spessore di circa 2-3mm e successivamente sono state ricoperte con un secondo strato di uguale spessore. Per ogni prodotto sono state effettuate quattro replicazioni. Le uova in assenza di substrato mostrano i valori medi di schiusura più elevati (95±0,4). I valori medi di schiusura più bassi sono stati osservati su farina di pinoli (6±0,7) e farina di mandorle (11,8±1,4), mentre quelli superiori a 90 si osservano per zucchero semolato, cannella in polvere, lievito di birra in polvere e aglio in polvere.

Abstract
The influence of food on eggs’ hatching of Plodia interpunctella (Hbn.) was valued; 24 substrates were tested. 100 eggs were placed on a first layer of product about 2-3mm thick and afterwards they were covered with a second layer of equal thickness. 4 replications were carried out for every product. In absence of food, the eggs show the highest average values for hatching (95±0,4). The lowest average values of hatching were observed on finely ground pine seeds (6±0,7) and on finely ground almonds (11,8±1,4), while those higher than 90 are observed for castor sugar, powdered cinnamon, dried yeast and powdered garlic.Pubblicazioni consigliate
