ECONOMIC RETURNS TO THE BOLL WEEVIL ERADICATION PROGRAM
No full textThe economic viability of the Boll Weevil Eradication program in Alabama, Florida, and Georgia is assessed based on a five-year survey of producers. Results indicate the program increases yield 100 pounds per acre. This implies a 19 percent internal rate of return for producers over a ten year period.Cotton, Pest management, Regional pest control, Crop Production/Industries,
FACTORS INFLUENCING WEST TENNESSEE FARMERS' WILLINGNESS TO PAY FOR A BOLL WEEVIL ERADICATION PROGRAM
No full textData from a survey were used to evaluate Tennessee farmers' willingness to pay for the boll weevil eradication program. Producer experience, boll weevil control costs, and attitudes about boll weevil damage and insecticide usage after the program were significant explanatory variables and had a positive influence on willingness to pay.Contingent valuation, cotton, regional pest control, pest management groups, Demand and Price Analysis, Resource /Energy Economics and Policy,
ECONOMIC RISK EFFICIENCY OF BOLL WEEVIL ERADICATION
No full textThe purpose of this study was to determine the economic risk efficiency of implementing a boll weevil (Anthonomus grandis [Boheman]) eradication (BWE) program in cotton (Gossypium hirsutum L.) producing regions of the Mississippi Delta. Alternative producer pest management practices and program cost sharing were incorporated into a biophysical cotton simulation model. Participation in a BWE program along with strict adherence to Cooperative Extension Service pest management guidelines proved to be the risk efficient practice.Crop Production/Industries, Risk and Uncertainty,

Diel susceptibility of the boll weevil, Anthonomus grandis boheman to certain organophosphorous insecticides
No full textStudies were conducted to determine the effect of the thermoperiod and photoperiod on the diel sensitivity of the boll weevil, Anthonomus grandis Bohemn, to organophosphorus insecticides. Other studies related to insecticide sensitivity, respiration and locomotion were also investigated. Experiments to develop a satisfactory technique for applying insecticide to boll weevils were conducted. The topical method of treating weevils with insecticide produced less variability than tests using a drench or a filter paper surface technique. The latter 2 methods were not different from each other. Boll weevils entrained in various thermoperiods at LD9:15 were treated topically with malathion at dawn and dusk. Weevils treated at dawn were more tolerant to the insecticide than those treated at dusk. In a similar experiment when weevils were caged on malathion treated cotton plants, moralities were 56 percent at dawn and 86 percent at dusk. Greater mortality was produced with equivalent dosages of insecticides in warm temperature than in cooler temperature regimens. Other experiments 4 techniques for treating boll weevils with malathion. In all treatments insects were treated hourly for 24 consecutive hours in photoperiods of LD10:14, 12:12 and 14:10. In each regimen weevils were more resistant to malathion at dawn than at dusk. In the majority of tests, the percentages of weevils killed were greater for those insects treated during the photofraction that the scotofraction. Mortalities from weevils entrained in LD10:14 were greater than for weevils in LD14: 10.
MODELING FARM AND OFF-FARM ECONOMIC LINKAGES TO ANALYZE THE IMPACTS OF AN AREA-WIDE INSECT MANAGEMENT PROGRAM ON A REGIONAL ECONOMY
No full textThis study evaluated the impacts of the boll weevil eradication program at the farm level and on the west Tennessee region. Budgets, an acreage response model, and an input-output model were used to evaluate direct and indirect program impacts. The program generates small but positive economic benefits for the region.Crop Production/Industries,
Population suppression of the boll weevil, Anthonomus grandis Boheman, in the high and rolling plains of Texas
No full textA total population suppression program was directed against the boll weevil, Anthonomus grandis Boheman, in an 8-county area of the High and Rolling Plains of Texas during 1964-66. During the fall of 1964, technical malathion (95%) was applied by the low volume technique at the rates of 12 - 16 fl. oz/acre in an area-wide diapause boll weevil control program. The spray program was modified into a 2-phase program in 1965 and 1966. The first phase was designed to destroy the last reproductive generation of boll weevils, while the second phase was designed to destroy diapausing broods. The 2-phase, or reproductive-diapause method, was found to be much more effective than the diapause control program conducted in 1964. The reproductive-diapause control technique proved to be highly effective for suppression of boll weevil populations. The boll weevil population within the suppression zone was reduced as much as 99% over the population in untreated areas outside the control zone. Boll weevil infestations on the High Plains were reduced to very low levels by 1966. Boll weevil populations of low density within the suppression zone were found to be distributed in a nonrandom, clumped pattern following the 1965 suppression program. The distribution of cotton fields infested with weevils appeared to be influenced primarily by the abundance of favorable weevil overwintering sites within the cotton growing area, and also by the distance of these sites from the cotton fields. The majority of infested fields were adjacent to favorable overwintering habitats. Only a small percentage of the fields which were located more than 1/2 mile from overwintering sites were infested.
A PRINCIPAL-AGENT MODEL FOR REGIONAL PEST CONTROL ADOPTION
No full textInvestigating the underlying producer characteristics associated with regional pest control adoption revealed an interesting proposition. Early adopting producers of firm-specific techniques with characteristics including higher education, more specialized operations, and larger sized business units are dissatisfied with a regional pest control technique. This study provides an explanation of the proposition based on a principal-agent model. Empirical support for the proposition is also presented by developing a multinomial logit model for predicting producers' dissatisfaction with boll weevil eradication.Regional pest control, Principal-agent model, Proposition, Firm-specific, Industry-specific, Crop Production/Industries,
Review of Bad Boll Conferences
No full textBuilding Theological Bridges is the appropriate subtitle of the sainted Professor Fred. E. Mayer\u27s The Story of Bad Boll. In this booklet, which is a lasting memorial to Dr. Mayer\u27s synthetic and sympathetic mind, the author summarized the three theological conferences conducted by our Synod at Bad Boll, Wűrttemberg, Germany, in the summer of 1948. The readiness of officials of our Synod to build theological bridges connecting our Church with European Lutheran Churches was so favorably received by the participants in the first Bad Boll venture that in the opinion of our officials these conferences needed to be continued
