Different control measurements were tested against the oriental hornet Vespa
orientalis Fab. in three sites in Quena governorate representing Upper Egypt viz. Abu-
Tisht, Quena and Isna during two successive years, The results indicated that the
efficiency of using sweep-net as a method of control, the annual mean numbers of
captured hornets throughout the study period reached 3844.3, 2566.8 and 2351.9
individuals for the three study sites, respectively. Of the four tested types of traps, the Ministry of Agriculture trap (MAT) was
found to be the most effective one in trapping the hornet, while the hanged trap was
the least. The average collected number of hornets I trap! year reached 2755.8
individuals using MAT comparing with 58.6 individuals for the hanged trap.
Attractiveness of six baits viz. fermented sugar solution, fresh honey, fermented
honey, dead bees, fresh fish and animal lung were tested using MAT. Fish bait was
superior over all tested baits, while the dead bees bait was the least attractant. Chemical control methods were tested under laboratory conditions. Two forms
of applications viz. spray and poisoned baits were experimented using Lannate 90%,
Lannate 20% and Malathion 57%. According to the obtained data Lannate 90%
proved the highest efficiency against the hornet when applied either as spray or
poisoned baits.
