Popis:	Mean respiratory quotients determined on samples from individual drones by Cartesian diver respirometry averaged 0·64, suggesting that phospholipids constitute the major source of energy. The average sperm density of semen was 7·76 millions/μl. Dilution of semen increased the rate of oxygen consumption by 68 per cent. Semen stored at 13 to 14°C for 1 month showed only 40 per cent of the oxygen uptake of freshly ejaculated semen. Streptomycin sulphate treated samples of semen showed significantly lower rates of oxygen consumption than untreated samples. These results suggest that the high density of sperm in the semen and low metabolic activity during storage may be at least partly responsible for the successful long-term storage of honey-bee spermatozoa.
