than ether genotypes; (2) the composition of normal flora can affuct boll weevil 

 feeding and egg laying preference; (3) normal flora composition in soioe cotton 

 genotypes can be artificially manipulated by inoculation, to increase boll weevil 

 resistance; (4) certain species of Bacillus and Pseudomonas in cotton normal flora 

 are major contributors to the boll weevil resistance mechanism; (5) boll weevil 

 resistance due to certain normal flora compositions is reflected in; (a) increased 

 earliness in fruit set and development, (b) increased number of total bolls, and 

 (c) increased yield compared to an isogenic check containing a different normal 

 flora composition.

 literature for the boll weevil, Anthonomus grandis . Bull. Entomol. 

 Soc. Am. 25: 19-23. 



Our purpose is to provide research scientists, interested in host plant resistance 

 to the boll weevil, with a bibliography which is as complete and up-to-date as 

 humanly possible. The literature cited includes proceedings, technical, and 

 popular articles. Several publications dealing with boll weevil behavior, natural 

 mortality, and laboratory culture are also included to better acquaint the scientist 

 with the complexity of this plant-pest system. Host plant resistance is by nature 

 an integrative science; the effects of weather, soil, natural enemies, and the ge- 

 netics of both host plant and insect herbivore form a constellation of interactive 

 factors which controls pest behavior and survival, and ultimately, crop yield. 

 These factors must be considered if host plant resistance studies on the boll 

 weevil are to be meaningful.
