Abstract EN

This research was carried out to test the attraction of Red flour and Khapra beetles insects to six food packages, as follows : gunny, polyester, plastic reticular, cellophane, nylon and paper.

This attraction is carried out during the first larval star, pre-lasted larval star and mature stage.

The results revealed that no significant differences in percentage mean values of attraction of the two beetles.

The results showed that there are no significant differences in mean percentage values of attraction to the first larval star to gunny, plastic reticular and cellophane, as follows :12.26, 12.86 and 13.26 %.

On the other hand, significant differences in mean percentage values of attraction to cotton, nylon and paper are detected, as follows : 18.44, 15.65 and 15.55 % respectively.

Moreover, pre-lasted larval star showed significant differences in percentage mean values of attraction to gunny, cotton, plastic reticular, cellophane, nylon and paper, as follows : 17.7, 17.0, 16.0, 14.7, 12.5 and 13.0 %, respectively.

Significant differences in percentage mean values of attraction of mature stage of Red flour and Khapra beetles to paper, cotton, nylon, gunny, plastic reticular and cellophane are, as follows : 17.31, 15.92, 15.62, 14.52, 12.86 and 11.54 %, respectively.
