Olfactory Responses to Milk Powder on Foodstuff Pests

Abstract

The chemotaxis to milk powder on principal foodstuff pests were examined using the Y-tube olfactometer (Fig. 1).
The samples tested were 14 species (Periplaneta fuliginosa, Blattella germanica, Trogoderma granarium, Oryzaephilus surinamensis, Cryptolestes minutus, Tribolium castansum, Lasioderma serricorne, Rhizopertha dominica, Sitophilus zeamais, S. oryzae, Cadra cautella, Ephestia kuhniella, Plodia interpunctella and Bracon hebetor).
The experimental results were as follows: Attractive species was Bracon hebetor alone, and the other all species were ineffectiveness.
