Africanized bees start foraging at a younger age than European bees when compared in their own colonies. However, behavioral maturation depends also on colony environment. When European bees are raised in Africanized colonies they start foraging ever younger age than Africanized bees. We hypothesized that changes in contractile proteins also depend on colony environment. To test “colony environment hypothesis” we cross fostered Africanized and European bees in Puerto Rico and compared their foraging behavior and contractile protein changes throughout the 3 week development period. Our results show that In European colonies European bees started foraging at younger ages than Africanized bees. These suggest colony environment influences behavioral development.
