Studying the Seasonal Activity of Termites Microcerotermes diversus Silv. using Bait Stations in Nineveh Governorate

Abstract

The study was conducted in the forest nursery of the Department of Forestry / College of Agriculture and Forestry / University of Mosul, The results showed that the number of ground workers varied significantly among them according to the stations and the date of examination, and that the first appearance of the workers inside these traps was in the fourth week of April, with an average of 26.67 99 workers / station at the averages of 29 °C and 64.7% for the temperature and relative humidity, respectively. The number of worker bees reached its peak on 1/5 with an average of 99 workers / station at the mean averages of 33°C and 60% for the temperature and relative humidity, respectively. After that, the numbers of these workers continued to gradually decrease in numbers to disappear (zero / station), in the last week of June and the first week of July 1/7/2021, at averages of 42 °C and 33% of the temperature and relative humidity, respectively. To reappear again and forcefully, at the beginning of the second week of September, with an average of 134.67 workers / station, at an average of 38 °C and 30% of the temperature and relative humidity. The presence of this insect continued after that during the months of October and the first week of November, to disappear again. again during the second week of November, specifically on 112021/15/, and for all used bait stations (zero / station), at averages of 25 °C and 60% of the temperature and relative humidity, respectively. The results of the study of the correlation between temperatures and relative humidity on the one hand, and the number of these workers during the study period 2021 showed that there was a negative and insignificant correlation (-0.212) between the number of land workers and the average temperature, while the correlation was positive and insignificant (0.227 +) between the number of ground workers and humidity Relativity.
