Abstract

This experiment was done during spring and autumn seasons of 2019 and 2020 to study the effect of age, feeding supply and the active season of honeybee workers on morphometric characters of venom sac and venom acid gland, body weight and the ages from 1th to 21th day old. Results indicated that in spring season, the highest data were recorded for body weight (122 mg) at day 8th, venom sac area (1.554 mm2) at day 17thand the total length of acidic gland (15.76 mm) at 12thday old. While the lowest venom sac area (0.942 mm2) was recorded at 1stday old. In autumn season with plenty of bee bread, the highest data were recorded for body weights at day 9th (116mg), the highest both of venom sac area at day 15th (1.5346 mm2) and the total length of acidic gland at 13th day old (15.3mm).With scarcity of bee bread in autumn season, the body weight at day 1st recorded (94 mg) while it recorded at day 21th (79mg), the highest venom sac area at day 20th (1.1933 mm2) and the highest total length of acidic gland at 17th day old (15.4 mm). With scarcity of bee honey in autumn season, the highest body weights at day 1st (94 mg), while the lowest body weights at day 21th (72 mg), the highest venom sac area (mm2) at day 19th (1.1775 mm2) and the highest total length of acidic gland at 12th day old (15.5 mm).
