Bio-chemical changes in the brain, lead to bio-chemical alternations of biologically active molecules and enzymes. These bio-chemical changes in A. cerana indica bridge the gap between initial responses and behavioural activity. The amount of protein present in the brain of A. cerana was 12.42 (± 0.02) during rainy season, 10.90 ± 0.01 during winter and 9.81 ± 0.01 during summer. Where as AchE was more during summer (20.5 ± 2.21) and less (7.33 ± 2.1) in rainy season. Amino acids were also recorded more in summer (9.11 ± 0.11) and less (6.11 ± 0.11) in winter. These variations can be attributed to the activity of foragers. During summer the foragers are more active in collecting the nectar and pollen as a result the stimulation takes place in brain, at the same time the high temperature during summer acts as a stimulator to neuronal activity.
