EFFICACCY OF NEW DESIGNED TRAPS FOR CONTROLLING THE ORIENTAL HORNET (VESPA ORIENTALS) IN EGYPTIAN APIARIES AND ITS MEASURMENTS

This study was carried out at a private apiary in Diarb Negm, Sharkia governorate and Meat Ghamr Region, El-Dakhlia Governorate, Egypt, during 2012, 2013.Results showed the monthly average numbers for catching of V. orientalis adults was recorded at October followed by September and November. The best trap was the new trap with mean captured wasps 72.11, 82.34, 77.63 and 75.31 for Sharkia, Dakhlia governorate at both 2012, and 2013 years, respectively .also , results showed the monthly average numbers for catching of V. orientalis adults in the four directions during 2013. From which it can be seen during 2013 season that the highest population of V. orientalis adults was recorded at October followed by September and November. Results , also showed that the comparison between the new trap and bottle trap at the four directions (East , West, North and South ) to evaluate the recommended directions to the beekeeper . As a conclusion, the highest occurrence of V. orientalis was at east and south direction and the lowest mean at north and west directions. Results showed the monthly average numbers for catching of V. orientalis adults in the three heights (0.5, 1.0 and 1.5 m above the land) during 2013. From which it can be seen during 2013 season that the highest occurrence of V. orientalis was at 1.0 m above the apiary land as best height. The results of this study reveal that the new trap (plastic bottle 20L.) was the best trap for the V. orientalis. The effect of trapping on populations sizes and suggests that trapping can be used to control the wasps populations. The obtained results obviously showed that , there were significantly influenced by the trap height. However, the efficacy of the trap at 0.5 m was the lowest of all. So, the use of new trap may be an efficient solution for controlling the wasps that invade bee hives in Egypt.
