Abstract
In this paper we report the behavioral responses of granary weevil to 6 blends of cereal volatiles. Four doses (1 ng minâ1, 10 ng minâ1, 100 ng minâ1, and 1000 ng minâ1 in 50 μl of hexane applied on filter paper) were tested. A Y-tube experiment revealed that females and males of Sitophilus granaries were attracted to the blend 1, 4, and 5 at concentrations of 10 and 100 ng minâ1, 10 ng minâ1, 1 and 10 ng minâ1, respectively. Moreover, females and males of granary weevil were not attracted to any concentration of blend 2 and 3. Yet, the weevil females and males were repelled by the highest concentrations (100 and 1000 ng minâ1) for all tested blends, except of blend 1, where concentration 100 ng minâ1 was an attractant for both sexes. Moreover, females and males were repelled by three tested concentrations of blend 6 (10, 100 and 1000 ng minâ1).
