Abstract
The study was conducted in the researcher's apiary located in the Salah al-Din governorate, Iraq. The experiment took place during the winter months of January, December, and February of the year 2021-2022 Which aims to evaluate the Overwintering period based on the temperature and humidity inside Lancastroth cells using a computer monitoring system. 15 cells were used in the experiment. were divided into different treatments: T1 as the control treatment using the usual Lancaster cells, T2 using Langstroth hives coated with secondary ceilings, and T3, T4, and T5 using Langstroth hives coated with adhesive walls of cork, Polyvinyl chloride (PVC), and Alkabon, respectively.The results of the statistical analysis of the data obtained from the computer control system showed that the treatments led to the preservation of heat inside the cells by preventing heat leakage to and from the cells. Additionally, there was a highly significant decrease (P≤0.01) in the relative humidity recorded inside the cells and brood by the computer control system during all experimental periods and the general average. The average temperature during winter 22.30, 30.25, 27.64, and 27.53 °C, while the humidity was 79.93, 66.81, 64.95, 61.34, and 62.44% in the treatments.
