Abstract | ||||
This experiment was carried out in navel orange orchard at ElKhattara region during two successive flowering seasons 1994 & 1995. Four releases of Tropinota squalida Scop. adults were carried out in each season, adults were collected, sexed and marked by fixed varnish colours, one colour for each releases (200 adults; 100 6+ 100 9). The releasing was applied at the flowering period which extended from March —May. It was found that, the majority of beetles were more attracted in descending order to the western, southern, S/W and S/E. These results may help in selecting the suitable sites for monitoring or control of T.squalida. The female adults longer distances than males, 68.4% males, 56.4% females flew to 50m., while 29.3% mate, 40.7% female flew a distance of 100m. A percentage of 2.3% males and 2.9% females recorded at distance of 170m. In general, 61.4% of the total released adults flew a distance of 50m., 36% flew to 100m. and 2.6% flew to a distance of 170m. | ||||
