Lifehistory. — Eggs are laid on clothing in which the lice live 

 except when actually sucking blood from the body. Egg 

 development much as in P. capitis. 



Food. Tin- blood of man. This louse has been induced to bite 

 fowls (Neveu-Lemaire) and is said to have been taken from c; tile 

 (Osborn), but is not known to attack anj host except man in a 

 natural state. 



Status. The bite oi the bodj louse is said to be more irritating 

 than that of the head-louse. The former is known to carry 

 Typhus Fever and both are equally to be avoided as possible 

 carriers of disease. 



Control. Personal cleanliness. Baking, boiling, or fumigation 

 of infested clothing or bedding. The newly-hatched young are 

 only able to exist about two days without food so that disuse of 

 infected clothing, etc., for a period of at least 10 days should result 

 in starving of any young emerging from eggs in the clothing. It 

 may, however, be noted that the eggs may not hatch for five 

 weeks in cold climates ; no exact observations on this point seem 

 to be on record for Southern India but the period may be expected 

 to be much shorter -probably always less than a week.
