    APPENDIX iil. A Bibliography of selected papers on the Bed-bus (Cimex Jectularius, Linn.) The papers have been grouped for convenience of reference into (i) Biological, (ii) Medical, (iii) Methods of control, (iv) Miscellaneous. This grouping is somewhat arbitrary, since many of the papers deal with the subject from several angles. The abbreviations used are those of the World list of Scientific Periodicals, 1927, vol. II. BIOLOGICAL. ARAKAWA, Y. (1932): Dobuts.Zasshi., 4,198. (In Japanese.) Stink glands ; poison in salivary glands. (1932): Insect Wld., 36, 335. (In Japanese.) The bite of Bed-bugs. Bacor, A.W. (1914): Bull. Ent. Res., 5, 111. Eggs of Cimex lectularius can live at 40° to 50° F. for 31 days and at 28° to 32° F. for 48 hours. Five to 8 days at the latter temperature reduced the percentage hatching to 25 per cent., and longer exposures (10 to 15 days) were fatal. Exposure to 113° F. prevents hatching. The eggs hatch after burial in dry or wet sand for about a week at 45° to 50°F. if they are then uncovered and kept at a favourable temperature. Immersion in water at 60° to 63° F. for 5 days has no effect on hatching if the eggs are then kept under favourable conditions. They also live for at least 3 days in water at 45° to 50° F. and for 48 hours when the water is frozen. Immersion in lime water for 46 hours is fatal. The eggs survive partial embedding in a wet plaster surface if emergence is not prevented. Newly hatched Bed-bugs when unfed can live at 28° to 32° F. for periods up to 18 days. They can also withstand chilling, thawing, re-chilling and again thawing over shorter periods. Exposure to cold moist air after a full meal is often fatal, probably because of humidity rather than cold. At moderate temperature (60° to 65° F.) they may live for 136 days unfed and after a meal 9 months. When unfed at 75° KF. with humidity between 0.65 and 0.70 the average life is 10 days, with occasional survival up to 21 days. At 88° F. with humidity between 0.70 and 0.80 the average life is 7 days, the longest survival being 11 days. At 96° F. with humidity at 0.25 the average life is 5 days ; individuals have survived for 8 days. Exposure to 113° F. is fatal within a few minutes. BucHNER, P. (1921): Biol. Zbl., 41, 570.
