| Abstract | ||||
| The study was carried out across three Egyptian governorates: Giza and Kafr El-Sheikh, specifically at the bee research department branches in Dokki, and Sakha. The goal was to assess how atmospheric temperature and relative humidity impact the activity of the oriental wasp, Vespa orientalis L., during the autumn season over two consecutive years, 2020-2021. Wire screen traps were used to monitor wasp population density, with data collected twice weekly. Throughout the study, average atmospheric conditions were recorded. in El-Doki in 2020 in October, the highest population was observed on October 7, with 55 individuals, the lowest was 16 individuals at 28 October. In November, the peak population was recorded on 4, with 27 individuals, the lowest was 4 individuals, observed in both November 24 and 28. In December, the highest population recorded was 2 individuals in December 2, the lowest wasp count was 0 individuals in December 9. Kafr El-Sheikh in October, the peak population was recorded on October 28, with 11 individuals, lowest population for October was an average of 5.33 individuals, recorded in both October 10 and 31. In November, the highest population was recorded in November 21, with 7.67 individuals observed, the lowest count was 0 individuals in November 4. In December, the highest population was observed in December 2, with an average of 5.67 individuals, the lowest count for December was 1.67 individuals in December 5. | ||||
