  • 2019 National Cotton Council Report to Members
    2019 National Cotton Council Report to Members The Memphis-based National Cotton Council communicates united industry positions on various issues to appropriate government bodies and works for U.S. policy that assures worldwide competitiveness and protects member's income. The NCC has compiled an impressive record of advocacy for an industry in which farms and businesses directly involved in the production, distribution and processing of cotton employ more than 125,000 workers and produce direct business revenue of more than $21 billion. Accounting for the ripple effect of cotton through the broader U.S. economy, direct and indirect employment surpasses 280,000 workers with economic activity of almost $100 billion. This report is sponsored by Farm Credit. Joint Message from the Chairman and the President Throughout 2018, the National Cotton Council (NCC) addressed economic challenges facing the U.S. cotton industry. Efforts on securing near-term assistance involved pursuing another gin cost-share program. The NCC also conducted regional informational conference calls and webinars regarding provisions of the 2018 Seed Cotton Program that Congress approved early in the year. Long- term stability also involved protecting the industry’s farm policy priorities in the new farm bill as it was developed, debated and signed into law late in 2018. The NCC was very active on the trade front, ranging from monitoring the development of the U.S.-Mexico-Canada Agreement to discussions regarding China’s market access. The NCC also monitored the implementation of the Market Facilitation Program authorized by the Administration to help mitigate the economic effects of China’s retaliatory tariffs.

Sci. 42(3): 392-398 (July 2007) Key Words trap design, Anthonomus grandis grandis, cotton Boll weevil, Anthonomus grandis grandis Boheman, eradication is nearing comple­ tion throughout the U.S. as all cotton-producing regions are in active or posteradica­ tion maintenance, with most of the active eradication occurring in Texas. The success of eradication is almost entirely based on boll weevil traps baited with grandlure and a weekly trap capture threshold of 1 weevil per trap per week used in active eradi­ cation zones (Dickerson et al. 2001, Cotton Foundation, Memphis, TN, 627 p.). The Texas Boll Weevil Eradication Foundation uses a standard 10 mg grandlure dis­ penser (Scentry Biologicals, Billings, MT) and an impregnated kill-strip of 10% (wtwt) dichlorovos DDVP ([2,2,-dichlorovinyl dimethyl phosphate]; Heron Environmental, Emigsville, PA) to kill boll weevils in the trap and prevent their escape (Suh et al. 2003, J. Econ. Entomol. 96: 348-351). Even when a DDVP kill-strip is used in a boll weevil trap in South Texas, a significant impedance to trapping efficiency can be the predation of boll weevils by insects and spiders that enter the capture area of the trap. Spiders have been implicated as a significant factor in interfering with trapping effi­ ciency by preying on boll weevils or, more importantly, by webbing the entrance of the trap making it impossible for weevils to enter the capture container (Armstrong and Richman 2006, Proc.

Although adults can (Coleoptera: Curculionidae), belongs to a group of beetles characterized by an elongated snout (or probos- cis). The adult boll weevil is about 1⁄4 inch long. Re- cently emerged adults may have a slightly reddish hue, but adult color typically varies from gray or brown to nearly black. The boll weevilʼs snout is about one-half the length of its body. Chewing mouthparts are located at the end of the snout. Boll weevils can generally be separated from other weevils by the presence of two spurs on the femur of each front leg, with the inside spur being larger than the outside spur. Immature life stages, including eggs, larvae and pupae, are found inside squares or bolls. Eggs are small and embedded inside squares and bolls, and thus are not visible. The larval and pupal stages of the boll weevil are found inside squares or bolls. Larvae are white to cream- Boll weevil colored, legless and about 1⁄2 inch long when fully de- veloped.

One of the alternatives for its control is the uti- lization of Bacillus thuringiensis (Bt), an entomopathogenic bacterium characterized by its production of insecticidal crystal proteins. Embrapa Genetic Resources and Biotechnology has a collection of Bacilli in which diVerent isolates of Bt are stored. A method for rear- ing and maintenance of Anthonomus grandis on artiWcial diet in the laboratory was developed, and a robust larval bioassay protocol was established for the selection of B. thuringiensis isolates toxic to boll weevil. After preliminary bioassays performed with 215 isolates, 5 were selected that demonstrated a good level of toxicity and these were analyzed in more detail. The most toxic were S601 and S1806 pre- senting LC50 (lethal concentration to kill 50% if the larvae) of 0.14 mg/ml and 0.30 mg/ml, respectively.

Paper prepared for the American Political Science Association meetings. Boston, Massachusetts, August 31, 2018. We thank Dimitrios Halikias, Katy Li, and Noah Nardone for research assistance. Richard Richards, chairman of the Republican National Committee, sat, alone, at a table near the podium. It was a testy breakfast at the Capitol Hill Club on May 19, 1981. Avoiding Richards were a who’s who from the independent groups of the emergent New Right: Terry Dolan of the National Conservative Political Action Committee, Paul Weyrich of the Committee for the Survival of a Free Congress, the direct-mail impresario Richard Viguerie, Phyllis Schlafly of Eagle Forum and STOP ERA, Reed Larson of the National Right to Work Committee, Ed McAteer of Religious Roundtable, Tom Ellis of Jesse Helms’s Congressional Club, and the billionaire oilman and John Birch Society member Bunker Hunt. Richards, a conservative but tradition-minded political operative from Utah, had complained about the independent groups making mischieF where they were not wanted and usurping the traditional roles of the political party. They were, he told the New Rightists, like “loose cannonballs on the deck of a ship.” Nonsense, responded John Lofton, editor of the Viguerie-owned Conservative Digest. If he attacked those fighting hardest for Ronald Reagan and his tax cuts, it was Richards himself who was the loose cannonball.1 The episode itself soon blew over; no formal party leader would follow in Richards’s footsteps in taking independent groups to task.

  • The Impact of the Boll Weevil, 1892-1932
    THE IMPACT OF THE BOLL WEEVIL, 1892-1932 Fabian Lange, Yale University Alan L. Olmstead, UC Davis Paul W. Rhode, Univ. of Arizona & NBER February 2008 Abstract: The boll weevil is America’s most celebrated agricultural pest. We assemble new county-level panel data on the insect’s geographic spread and on farm activity to investigate the weevil’s effects on the southern economy between 1892 and 1932. Our study provides sharp estimates of the full time path of the pest’s local impacts. We find that instead of diversifying away from cotton in anticipation of the weevil’s appearance, farmers attempted to squeeze one last large crop out of their land just prior to contact. Upon arrival, the weevil had a large negative impact on production which required up to five years to be fully manifest and which did not disappear within our study period. Cotton yields fell substantially; acreage declined by less. In response, farmers did not take land out of agricultural use instead shifting to other crops. We also find striking effects on land values and population movements, indicating the pest’s spread redistributed economic activity within the South. THE IMPACT OF THE BOLL WEEVIL, 1892-1932 The boll weevil, with its entourage of songs and folklore, is enshrined in many popular accounts as America’s most destructive agricultural pest. Testifying before Congress in 1903, the chief of the USDA’s Bureau of Plant Industry referred to the insect’s advance as “the wave of evil.”1 In his Annual Address to Congress in 1905, President Theodore Roosevelt discussed biological warfare when he alerted anxious cotton producers that USDA scientists had imported a predatory ant from Guatemala that fed on the weevil.2 The weevil was indeed a headline grabber.

  • Tenancy, Marriage, and the Boll Weevil Infestation, 1892–1930
    Tenancy, Marriage, and the Boll Weevil Infestation, 1892–1930 Deirdre Bloome, James Feigenbaum, and Christopher Muller⇤ January 2017 Abstract In the early twentieth century, the cotton-growing regions of the US South were dominated by families of tenant farmers. Tenant farming created both opportunities and incentives for prospective tenants to marry at young ages. These opportunities and incentives especially a↵ected African Americans, who had few alternatives to working as tenants. Using complete-count Census of Population data from 1900–1930 and Census of Agriculture data from 1889– 1929, we find that increases in tenancy over time increased the prevalence of marriage among young African Americans. We then study how marriage was a↵ected by one of the most notorious disruptions to southern agriculture at the turn of the century: the boll weevil infestation of 1892–1922. Using historical Department of Agriculture maps, we show that the boll weevil’s arrival reduced both the share of farms worked by tenants and the share of African Americans who married at young ages. When the boll weevil altered African Americans’ opportunities and incentives to start families, the share of African Americans who married young fell accordingly. Our results provide new evidence about the e↵ect of economic and political institutions on demographic transformations.
