ATIRACTIVENESS OF VOLATILE OILS AND PARAFFIN OIL TO THE ORIENTAL WASP (Vespa orientalis tab.) ATIACKING APIARIES

The oriental. Vespa orienta/is Fab. represents a big threat to the apiaries and
the mature fruits which necessitates t a it' s control. Some volatile, each a lone or
mixed with paraffin oil. were tested under field conditions at two districts of Gharbia
and Kaffr-Etshak Govemorats as lures for capturing the homet in the traps. The
volatile; Citraneliol, Geraniol, Linalool and Para-Coryophyllene were tested. These
volatile proved to be attractive to V. orienta/is but their attractiveness was greatly
enhanced when mixed with paraffin oil. Results indicated that the most attractive lure
was saturated sugar syrup mixed with paraffin oil, followed by only both saturated
sugar syrup or paraffin oil since insignificantly difference between them. The trap
catch was higher in August and September than in June and November. The
population of the captured hornet was higher in 2003 than 2002.
In a conclusion, using paraffin oil as lure for capturing the homet in the traps or
it's mixed, with sugar syrup was recommended, in order to Vespa orienta/is Fab.
control in the apiaries and fruit orchards.
