A REVISION OF THE GENUS \u3ci\u3eFURNARICOLA\u3c/i\u3e(MALLOPHAGA) WITH DESCRIPTIONS OF NEW SPECIES

The present paper has been prepared with much care for two reasons: The first and most urgent is to clarify the taxonomic position of the genus itself, which has been a controversial one since it was placed under the synonomy of Rallicola in the 1952 Checklist of Mallophaga by Hopkins and Clay. The second reason is to describe additional material which has been collected by the author since the genus was established in 1944 and also to record its occurrence on two other families of birds, from one of which no Mallophaga have previously been taken.. It will be noted that the bird hosts, with very few exceptions, have all been collected and prepared by the author himself, which has given him an unprecedented opportunity to verify the hosts in question and to check on any cases of suspected straggling

Reduction of Yield and Income Risk Under Alternative Crop Insurance and Disaster Assistance Plans

This study compares the effectiveness of five crop insurance/disaster assistance plans: an individual farm yield insurance plan similar to the current FCIC multi-peril program ; two area yield insurance plans; a farm yield disaster assistance plan; and an area yield disaster assistance plan. These methods are examined for reduction in yield and gross income variability with and without participation in the government deficiency payment programs using farm-level yield data from 98 dryland wheat farms and 38 dryland corn farms in Kansas . Although individual farm yield insurance is complex, suffers from moral hazard and adverse selection problems, and is likely to be the most expensive to administer , it provides more yield and gross income risk reduction than any of the alternative insurance/disaster assistance plans.Crop Insurance, Crop Disaster Assistance, Risk, Wheat, Corn, Risk and Uncertainty,
