- Abstract
The current experiment was carried out in the Faculty of Agriculture, Ain Shams University, Shoubra El-Kheima, Qualubia governorate, during the oriental hornet active season extended from September 1st until end of December 31st, 2015, to estimate the daily counts of the oriental hornet (Vespa orientalis L.) as well as its population dynamics during its active season. The experimental apiary composed of twenty four honeybee colonies, each contained seven frames covered with adult bees and four frames of them contained brood. The wasp’s traps were used for capturing the wasps during the day. The data summarized that, the average means of wasps captured for tested months were 8.79, 21.99, 13.42 and 1.10 wasp/trap for September, October, November and December 2015, respectively. The highest population of oriental hornet captured by the traps was recorded during October month, followed by November and September; meanwhile the population captured during December was the lowest, with significant differences between them. For daily count, the mean average numbers of wasps captured by the traps were 10.20, 17.55 and 6.22 wasp/trap for the three periods (9am – 12pm, 12pm – 3pm and 3pm – 9am of next day), respectively. The highest numbers of wasps captured by the traps were recorded during the noon period (12pm – 3pm) followed by morning period (9am – 12pm), meanwhile the afternoon and evening period (3pm – 9am of next day) recorded the lowest numbers of wasps captured by the traps, with significant differences between all the tested periods. Overall the highest numbers of oriental hornet captured by wasp’s traps were recorded in October month during the noon period, 12pm – 3pm and averaged (33.15 wasp/trap), followed by November month during the same period 12pm – 3pm (20.50 wasp/trap).
