Laboratory Quality Control Studies Of Sterility In Boll Weevils Produced For The Mississippi Pilot Eradication Experiment Classic Reprint

Excerpt from Laboratory Quality-Control Studies of Sterility in Boll Weevils Produced for the Mississippi Pilot Eradication Experiment By quality-control testing we mean the frequent monitoring of sterility in samples of treated weevils under carefully standardized conditions. A high-quality weevil is one that is permanently sterilized and which is still capable of competing with wild untreated males. Overall competitiveness or effectiveness of sterile males in the field depends on a number of factors such as the ability to produce pheromone and motile sperm, the capacity to mate, the level ofsterility, and mean longevity. We concerned ourselves only with the last two qualities, steril ity and longevity; they are of prime importance and can be measured easily under routine lab oratory conditions.

Excerpt from Boll Weevil Suppression, Management, and Elimination Technology: Proceedings of a Conference, February 13-15, 1974, Memphis, Tennessee These developments spurred the cotton industry, in 1958, to appeal to Congress for an overall program of research that would adequately deal with an ever-increasing boll weevil problem. Congress directed the Secretary of Agriculture to review the situation and submit a report of research and facility needs to meet the boll weevil problem. The Office of the Secretary appointed a study group to develop the information. The study group's report made two recommendations. The first provided for increasing ongoing re search at three of the Six locations where Federal research on the boll weevil was underway. The second recommendation provided for the establishment of the Boll Weevil Research Laboratory to concentrate on new approaches to boll weevil control. In 1960, Congress appropriated the necessary funding to implement the two recommendations. The intensified joint research efforts of the cotton industry, State agricultural experiment stations, and the us. Department of Agriculture during the next 8 years resulted in the develop ment of a number of extremely promising suppression measures. These achievements prompted the National Cotton Council of America, in 1969, to appoint a special study committee on boll weevil eradication. This committee, with the help of a technical advisory group, considered actions that should be taken if and when research advanced to the stage that boll weevil eradication might be considered to be technically and operationally feasible. In a meeting of this committee and its advisory group, held on May 6, 1969, reports of progress in research suggested that suppression tech niques might already have been developed to the extent that eradication might be achieved. Therefore, the committee felt that a pilot experiment was necessary to test the various suppression measures. A special subcommittee made numerous onsite visits to various boll weevil infested areas and eventually chose an area in south Mississippi, in cluding adjoining areas of Alabama and Louisiana, for the experiment. The area was chosen because it was regarded as one of the most difficult areas in which to achieve eradication. The Pilot Boll Weevil Eradication Experiment, the largest entomological experiment ever attempted, encompassed a land area of approximately square miles, of Which approximately was planted in cotton. A Technical Guidance Committee was appointed to provide overall guidance for the conduct of the experiment and liaison with the numerous industry, State, and Federal groups involved, and to assess the results of the experiment. Funding was provided by the State of Mississippi. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
