1. Wax glands consist of _4_pairs on the __worker_ bee. 2. Glands: Write a brief description of what these glands do: Nasonov - located in the abdomen to attract other workers (citrol and geraniol) Mandibular Several secretions include queen substance ,9-OD, Alarm Hypopharyngeal - brood food, royal jelly 3. Alarm pheromone- banana oil, stimulate bees to sting (Koschevnikov gland and sting gland work together ) Dufour s gland-egg recognition secretion Tarsal gland- the foot print pheromone of trails 4. Describe the eye site of a honey bee. Use these words ultra violet, polarized, ocelli, ommatidia, compound, facet. 5. The antenna 6. False - It is part of the proboscis. 7. False 8. odor taste temperature color humidity
Dorsal Aorta Dorsal Heart hemolymph aorta, heart, ostia and open circulation system Thorax location is called the dorsal aorta -in the abdomen is called the dorsal heart. The part in the abdomen, has small holes in its sides. These holes are called ostia. The dorsal heart pulses, pulling hemolymph through out. The hemolymph percolates through the body bathing the various internal organs absorbing nutrients acquired during food digestion and reenters the dorsal heart to start the cycle again.
C. Esophagus, honey crop, proventricular valve, ventriculus (mid gut), Malpighian tubules. Malpighian tubule system: The system consists of branching tubules extending from the alimentary canal that absorbs wastes from the surrounding hemolymph. The wastes then are released from the organism in the form of solid nitrogenous compounds. spaghetti-like extensions of the tract that float freely in the bee s body cavity. The Malpighian tubules extract waste products from the hemolymph. They produce uric acid granules. The hindgut, or final section of the digestive system, is composed of the ileum (Figure 1) and rectum (Figure 1). The ileum, sometimes called the small intestines, is a short tube that connects the midgut to the rectum. The rectum is important for the absorption of water, salt, and other beneficial substances prior to waste excretion. These sections reabsorb >90% of the water that was used by the Malpighian tubules to collect waste. Bees, like most insects, try to retain as much moisture as possible from the food they eat. They tend to defecate moderately liquid to dry feces, (such as the shells of pollen grains). The system is named after Marcello Malpighi, a seventeenth-century anatomist.

10. In adult queens and workers only seven abdominal segments (A1-A7) are visible. In drones there is also visible eighth abdominal segment A8 and ventral part (sternite) of ninth abdominal segment.
