 studies vf diseased natural populations, with particular reference to

 This paper presents the fundamental principles governing disease-free rearing 

 systems. The possible sources of contamination are categorized as: (1) the 

 insects themselves; (2) the physical facilities and associated equipment; (3) 

 the expendable supplies; (4) the air; and (5) the personnel. This paper 

 presents methods for exclusion or control of contamination occurring from 

 each of the sources. The basic plan of a model system includes three phases: 

 (1) a stock colony that produces a quantity of the desired stage, generally, 

 the eggs; (2) a separate handling area where the rearing media is prepared 

 for the mass production colony; and (3) the rearing area where the uiass 

 colony is produced. This progressive unilateral movement of insects and 

 their media, without recycling to the stock colony, guarantees preservation 

 of the integrity of the colony and its descendants. The author provides 

 a plan and specific details of a facility for mass rearing of the cotton 

 boll weevil, Anthonomus grand is Boh. This system posesses the capability for 

 extremely regular and reliable production from the colony of five million 

 adults per week.

 of ratios of cottonseed oil to invert sugar on quantity ingested and 

 initiation of a feeding response. J. Econ. Entomol. 69: 374-376. 

 The importance of ratios of cottonseed oil to invert sugar in formulations of 

 bait used against Anthonomus g randis Boheman was evaluated by determining the 

 effect>-on weevil feeding responses and quantity ingested. Previous baits using 

 water as a major quantity and occasionally with fumaric acid added were compared
