To illustrate the general progress being made in the field, the commodity area 

 of cotton has been chosen, with which I have had the good fortune to be asso- 

 ciated for nearly 12 years. The Host Plant Resistance Program developed from 

 a few independent studies in Texas, Arkansas and North Carolina in the late 

 1950' s and early 1960' s to s major interdisciplinary, multi-state, USDA effort 

 in 1976. Results of the program are now becoming evident with output of 

 commercial and advance cotton breeder lines carrying resistance to a number 

 of insect pests. Also, information presented represents not only personal 

 research but efforts of many colleagues representing different disciplines 

 located especially in the States of Mississippi, Texas, Louisiana, Arkansas 

 and the Agricultural Research Service USDA, located in Texas and Mississippi.

Technology for mass rearing sufficient numbers of high quality boll weevils 

 (5,000,000 per week) to conduct the first two years of the North Carolina 

 Program exists at the Cast Boll Weevil Rearing Laboratory at Mississippi 

 State University. This capability is recent and has resulted from well 

 supported, intensive research following the South Mississippi Eradication 

 Experiment. The Cast Boll Weevil Rearing Laboratory at Mississippi State 

 University was designed and constructed to serve as a research laboratory 

 and not as a major production facility to support a large eradication pro- 

 gram. It does not have the design or the capacity to provide weevils for 

 an expanded eradication effort beyond the proposed North Carolina Trial 

 Program. Research at the Cast Boll Weevil Rearing Laboratory has shown 

 conclusively that mass rearing of clean, competitive boll weevils, requires
