Foraging behaviour of Carpenter bees, Genus Xylocopa: Xylocopidae:Hymenoptera, and the pollination of some Indian plants.
Alluri Jacob Solomon Raju and C. Subba Reddi
Carpenter bees, or species of Xylocopa, are prominent members of the Indian bee fauna. They are found throughout the year, foraging in daylight and rarely through the moonlit hours. Some plant species are adapted specifically to pollination mediated by nectar-seeking carpenter bees. Such flowers protect the nectar chamber against piercing. Some offer pollen from poricidal anthers as the only reward. By their flower-foraging behaviour, carpenter bees provide an excellent service to the plants they pollinate, especially obligate outcrossers like Gmelia and Cochlospermum.
The different types of foraging behaviour exhibited and the role played by carpenter bees in the pollination of various plant species occurring in Viahakapatnam, Coringa and Giddalur in Andhra Pradesh are discussed.
