| Abstract | ||||
| The seasonal abundance of oriental wasp (vespa orientalis) population attacking honeybee colonies was investigated based on the number of trapped workers in Minia region, during the two successive seasons of 2019 and 2020. Results revealed that V. orientalis workers were started to appear from July to December with a peak of activity during October. But a gradual decrease in V. orientalis numbers was observed during December of the studied seasons. On the other hand , the effect of this predator attack on the average no. of covered combs by bees was calculated. It is clear from the obtained results that the damaged colonies due to direct attack of this hornet were increased during active months to reach the maximum of destruction in October (5 and 4.5 in infested colonies as compared with 7.8 and 7 in un infested colonies). Mean while, a latent negative effect of this hornet was observed during December however, the average no. of covered combs by bees was 1.25 and 0 (as in infested colonies) as compared with 5.3 and 5 (un infested colonies).The two successive seasonal of 2019 & 2020, respectively. Moreover, the highest numbers of this orient horned was calculated at 6 pm during the mid of the two active months of September and October in the two seasons of 2019 & 2020 at Minia region. | ||||
