Xylocopa
Carpenter bees (Xylocopa spp.) are solitary bees of up to 2.5 cm
closely related to honey bees and bumblebees. They have a worldwide
distribution favoring warmer climates. Carpenter bee stings are rare.
However, a fatal case after a Xylocopa tranquebarica sting has
been reported in Sri Lanka.12 Three allergens have
been isolated in Xylocopa appendiculata ; a PLA2 similar to that
of bumblebees and honey bees, and two melittin-like
peptides.13 Currently, none of the allergens is
WHO/IUIS (World Health Organization and International Union of
Immunological Societies) accredited.
