EXPRESSION OF BODY AND HAIR COLOR IN 3 ADULT CASTES OF THE RED HONEYBEE APIS-KOSCHEVNIKOVI VON-BUTTEL-REEPEN, 1906 IN SABAH, BORNEO

Apis koschevnikovi bees were collected in Sabah, Borneo. A total of 30 3 workers from ten colonies were measured in 1995, and 500 workers, 20 0 drones and ten queens were investigated in 1996. Measurements were m ade of the width of the dark bands on terga II, III and IV. Drawings o f the different body color patterns were made. The workers are light o range with dark brown bands on abdominal terga. Body color patterns we re assigned to five groups. The successive groups are gradually darker . Queens and drones have different color patterns and are darker than the workers. The upper part of the head and the scutum are black, and the dark brown bands on terga are similar in all three bee castes. How ever, the light colored body parts such as clypeus, scutellum, and the light abdominal bands are light orange or orange in workers and light brown or reddish brown in the sexuals: queens and drones. The major g ene responsible for body color in A koschevnikovi is proposed to be de signated as Ko. Hairs covering the thoraces of workers, queens and dro nes are light orange, gold and gray, respectively. The gene responsibl e for the color of these hairs is proposed to be designated as Kh.
