Variations in population levels of citrus blackfly,Aleurocanthus woglumi [Hom: Aleyrodidae] and parasites during an eradication program in Florida

From November, 1976 until October, 1979 citrus blackfly,Aleurocanthus woglumiAshby and its parasite populations were sampled monthly in urban areas of Broward County, Florida. During this period, the parasites,Amitus hesperidumSilvestri andProspaltella opulentaSilvestri became established and exerted control onA. woglumi populations. Parasite succession was noted in thatA. hesperidum was first abundant and later replaced in abundance byP. opulenta. The 2 parasite species continued to coexist and exert mortality on low pest populations in spite of chemical spraying used for eradication showing that integrated control ofA. woglumi is a definite possibility now that the pest is well established in Florida.

Florida's coastal setback line—an effort to regulate beachfront development

Abstract The coastal setback line program in Florida represents an effort to achieve more efficient location decisions, protect beachfront properties from storms, and control beach erosion. This article examines the reasons why the regulation of shoreline development might be necessary, describes the coastal setback program in Florida, discusses some of the problems encountered in its implementation, and examines its potential success.

Environmental Impact Evaluation, Land Use Planning, and the Housing Consumer*

A number of states are following the federal government's lead and requiring environmental impact reviews of new development proposals. This paper examines ambitious EIR programs in Florida and California with the aim of assessing the costs and benefits of their programs, and, by extension, of state‐mandated EIR programs in general. The focus is on new housing production. The findings are that EIR shows some promise of enabling communities to better protect themselves from adverse side effects of new development. At the same time, EIR adds what appears to be a modest increment to the overall costs of new housing. However, because EIR has expanded local government planning options, one of the side effects of EIR is likely to be the enhanced ability of localities to exclude moderate income families from new housing.

An experience in program evaluation

University of Florida Gainesville, Florida Program evaluation has become synonomous with designing educational programs, especially for those involved in the design of programs for state and federal funding. Follow Through, to a large extent, is probably a major reason for the present emphasis on evaluation since a universal problem for all of the Follow Through Models has been the development of an adequate evaluation design. This paper draws upon the conceptual and historical aspects of some of the present evaluation problems experienced in Follow Through, as well as some of the practical solutions that have been explored. The purpose of this paper is: 1) to examine three major problems that have occurred in translating evaluation theory into practice; 2) to clarify misconceptions about these problems and the evaluation process; and, 3) to suggest ways of avoiding these problems in future program evaluation efforts. A number of excellent references are available to the reader who wishes more specific, yet practical outlines for evaluating educational intervention programs (Anastasiow and Hanes, 1976; Olmsted, Ware and Newell, 1976, and Ware, Olmsted and Newell, 1976).

Research, application, and experience with precast prestressed bridge deck panels

This state-of-the-art report on precast prestressed concrete deck panels presents a summary of recent research, a discussion of the design, manufacture and installation of these panels, and a report on past experiences with precast panels. Several design recommendations, derived from recent testing programs in Texas, Pennsylvania and Florida, are suggested. First, butt joints should be used. Secondly, the strands in the panels should be placed at the centerline of the panels and spaced uniformly across the width. This reduces stress concentrations which could cause cracking and eliminates any camber which could lead to thin slabs. Finally, reinforcing ties are not necessary.

Competency-Based Teacher Certification Programs in Florida -- MYTH or Reality?

What is competency-based teacher education and what implications does it hold for inservice teacher preparation and eventual certification? According to Houston^, it is best defined as a program that has emphasis on objectives which are known to the student prior to instruction. Activities are then designed to contribute to the student's demonstration of the objec tives, and evaluation is in terms of accomplishment of these objectives. This implies that a series of com petency requirements could increase in complexity and scope as the teacher gains experience. More simply stated, competency-based programs involve preparing teachers for specific performance competencies and certifying them on the basis of collected evidence^.

Florida's Program for Economical Citrus Production1

Abstract Research in the Institute of Food and Agricultural Sciences (IFAS) has developed production techniques whereby oranges can be produced for approximately 30-35¢ per 90 lb. box (40.8 kg). However, a 1968 survey has indicated that many growers had costs several times this figure. To counteract this, extension specialists at the University of Florida developed a “Program for Economical Citrus Production.” A research-documented text with an extensive bibliography and a series of charts with duplicate 35 mm colored slides for group presentation was prepared. Extension citrus agents received packages of the text material along with intensive training in each segment of the program. This text material is now used in a unified, statewide program whereby all extension personnel concerned with citrus can conduct intensive programs on specialized topics.

Community mental health concepts as demonstrated by suicide prevention programs in Florida

There are certain basic principles of commuity mental health that may be demonstrated by the operation of a sucide prevention center. The most significant of these principles - that relating to the integration of each separate service into the total network of the health and welfare system of a community - can be achieved by the careful and deliberate planning of the administrative functions in the design of the service. This paper outlines a general organizational model in which the major unit is the Community Advisory Board. The members of this Board are able to effect the policies and procedures that enable the suicide prevention service and the other existing agencies to make maximum use of one another. Specific examples are reported to show how this model has worked in two communities of Central Florida.

Reproductive Performance of Crossbred and Straightbred Cattle on Different Pasture Programs in Florida

A study was made of 3,994 pasture matings in beef cattle at the Florida Range Cattle Experiment Station from 1944 to 1958. There were three groups of straightbred cattle, including Brahman, Shorthorn and grade Shorthorn. There were nine crossbred and mixed groups classified on the basis of breed of sire to which mated and breed composition of cow. Six different pasture programs were represented. Other variables included lactation status of the dam during the breeding season, age of cow at calving and year. The data were analyzed by the method of fitting constants. Due to significant interactions, constants were obtained from within-lactation status analyses also. Weaning percent and preweaning death loss are the dependent variables reported. Lactation status exerted the greatest influence with lactating and non-lactating cows having calving rates of 63% and 84%, respectively. There were highly significant interactions of lactation status with pasture, year and breed group. Overall weaning rate for pastures varied from 64% in all native range to 78% in improved pasture with supplemental feed. Non-lactating cows had weaning rates similar on all pastures with a slight advantage for pasture programs containing native range. For lactating cows, however, there was a marked advantage in weaning rate for cows on improved pasture compared to native range. Age of cow had a pronounced effect in both lactating and non-lactating cows. Lowest reproduction rates occurred in 2- and 3-year-old cows increasing to a peak at 6 or 7 years after which non-lactating cows remained nearly constant to 18 years while lactating cows declined slightly. A significant interaction of age and lactation status resulted because the lowered reproduction of young cows was more pronounced in lactating than in non-lactating cows. A significant breed by lactation status interaction resulted because non-lactating cows of all breed groups performed at nearly the same levels while lactating cows showed wide breed differences in weaning percent with deviations from the mean ranging from −19% to 18%. Within-group comparisons showed an apparent effect of breed-of-sire on weaning percent with crossbred bulls ranking lowest, Brahman next, and British breed bulls highest. Among females included in a Brahman-Shorthorn crossbreeding comparison, the deviations from the mean for cows classified on proportion of blood were −6.7% for purebreds, −2.9% for 3/4 bloods and 14.2%, for F1 females. Grade Shorthorns were an exception to generally poor performance of straightbreds with a deviation of 12% compared to −10% for purebred Shorthorns.

The Role of Attractants in the Recent Mediterranean Fruit Fly Eradication Program in Florida

The invasion of Florida by the Mediterranean fruit fly ( Ceratitis capitata (Wied.)) in 1956 was similar to that in 1929 in that the insect was initially discovered in April in grapefruit and eradication was completed in 18 to 19 months. The eradication programs were quite different however, the manpower required in 1956-57 being more than 85% less, because of the availability or highly effectors lures, plastic traps and bait sprays. Eradication was achieved with a minimum of removal and destruction of ripening fruit and little adverse effect on Florida’s agricultural economy. The sprays also greatly suppressed house flies ( Musca domestica L.) and mosquitoes. Some species of tropical fish in very shallow water were susceptible to the small amounts of malathion in the bait spray. Other authentic cases of injury to persons, livestock, birds or pets were not discovered. Lacquer-type automobile finishes were injured when spray droplets were not washed off soon after deposition.

Screening Relatives of Diabetics in Five Florida Counties

T HAT DIABETES runs in families has been recognized for many generations, but this knowledge is seldom applied to community diabetes detection programs if one judges by the literature. Screening relatives of persons with diabetes is a continuing activity in Florida. This report describes the detection project in IHillsborough, Jefferson, Madison, Suwannee, and Taylor Counties during the period January through June 1958. Programs for diabetics in Florida began in 1935 when a member of the State legislature for Polk County, who was a diabetic, presented a bill to provide funds to purchase insulin for the indigent diabetics in the State.. The legislature has appropriated funds for this purpose, included in the State board of health budget, for every year except one when the item wa.s not included in the budgetary request. The appropriation for 1959 was approximately $40,000. In 1946 the Public Health Service conducted a diabetes scre.ening de.monstration among the general population of Duval County, including Jacksonville. The Service also provided educational services, conducted classes for diabetics, and made other studies. Subsequently the State board of health used a trailer that toured various counties to conduct diabetes screening among the general population. The trailer service was discontinued about 8 years ago because of lack of funds. One of the studies related to the 1946 demonstration undertook to determine the prevalence of undetected diabetes among blood relatives of known diabetics in Duval County. The basis for the study was the long-observed, familial pattern of diabetes confirmed by numerous genetic studies. In the Duval County study (1) during the 3-year period from 1947 to 1950, 1,741 relatives of diabetics were given laboratory tests for diabetes, and 73 new cases of diabetes (4.2 percent of those tested) were discovered. The percentage of cases detected among relatives of diabetics was found to be about five times as high as the percentage found in screening general population groups. After several years during which casefinding activities based on screening relatives of known diabetics were not feasible, the Florida State Board of Health undertook in 1957 to capitalize on the unique opportunity afforded by the State's purchases of free insulin for indigent diabetics. In 1957 approximately 2,700 diabetics received part or all of their insulin through the State board of health. Casefinding among relatives has several advantages which were helpful in reactivating the diabetes detection program in Florida. Screening can begin with small groups of persons and yet have a sufficiently high rate of yield to make a small program productive.
