Abstract
The present research work was planned
considering the importance of linseed in the rabi oilseed economy of Bihar. The
field works were conducted at Mushari block of Muzaffarpur district, Bihar
during rabi season in two consecutive years 2022-23 and 2023-24. Linum usitatissimum
was cultivated in the experimental plots and the number of foragers (Apis
mellifera and Apis florea) were noted at 900h, 1100h, 1300h and
1500h of the day at one-week intervals. In both years the mean population of Apis
species on linum was highest at 900h and lowest at 1500h. Apis florea
were the dominant visitors followed by Apis mellifera. To document the
impact of weather factors on foraging behaviour, the abundance of Apis
mellifera and Apis florea was correlated with mean temperature and
mean relative humidity. Mathematical regression models revealed the combined
contributions of temperature and relative humidity to populations of Apis
mellifera and Apis florea. The present study suggested that the
populations of both the Apis species were increased with increase in
temperature and decrease in relative humidity.
