AbstractThe naturally occurring weevil (Curculionidae) fauna of Dade and Monroe counties in southern Florida is composed of 100 genera and 222 species. Another 20 species are adventive; their presence is due to the unintentional action of humans. Twenty-eight species occur only on the islands of the Florida Keys, 118 species occur only on mainland south Florida, and 76 species are shared by the mainland and the islands. Greater habitat diversity on the mainland accounts for its higher species diversity. The species distributions and faunal affinities are 60% Nearctic and 40% Neotropical or West Indian. Thirty-five species are known to occur only in southern Florida. This probably reflects poor knowledge of their distribution in the Caribbean rather than southern Florida as an important site for species origin. Most of the weevil species (133; 60%) are habitat specific and few species (22; 10%) are found in three or more habitat types. Wetland-inhabiting species are predominant (76; 34%), followed by hardwood hammock species (47; 21%). Flightlessness in adults is uncommon (35 species; 16%), but more prevalent in the species endemic to southern Florida (12 species; 34%). Extrapolation from data on weevil diversity yields a conservative estimate of over 5000 species of insects in southern Florida.

Relative Differences

Abstract Lake Okeechobee, located in southern Florida, is an important component in the regional hydrologic system. Currently, the Southeast River Forecast Center (SERFC) is setting up a forecasting scheme for Lake Okeechobee and its major inflows. An important aspect in calibrating the system is estimating the depth of direct precipitation over the water surface. Within this project, National Weather Service (NWS) and South Florida Water Management District (SFWMD) surface gauges, along with stage III multisensor precipitation estimates, are used to create time series of mean areal precipitation (MAP). The computed MAP values are compared in order to find the relative differences between them, and to determine the utility of using each data source for calibration and in future operations. It was found that the SFWMD gauge-based MAP was the most useful data source, because it had a suitable period of record and the SFWMD gauges had a better spatial sampling of precipitation over the lake surface. The radar-based stage III estimates were not found to be a useful source of data, despite the superior spatial sampling resolution, because they had too short a period of record and a number of changes in the processing algorithms made the associated MAP nonhomogeneous and inappropriate for model calibration.

Abstract The authors analyze 105 yr (1901–2005) of tropical cyclone strikes at 45 coastal locations from Brownsville, Texas, to Eastport, Maine, with the primary objective of examining spatiotemporal patterns of storm activity. Interpretation of the data suggests that geographically, three focal points for activity are evident: south Florida, the Outer Banks of North Carolina, and the north-central Gulf Coast. Temporally, clusters of hyperactivity are evident in south Florida from the 1920s through the 1950s and then again during the most recent years. North Carolina was a region of enhanced activity in the 1950s and again in the 1990s. A more consistent rate of occurrence was found along the north-central Gulf Coast; the last two years, however, were active in this region. Return periods of tropical storm strength systems or greater range from a frequency of once every 2 yr along the Outer Banks of North Carolina, every three years on average in southeast Texas, southeastern Louisiana, and southern Florida, and about once every 10–15 yr in northern New England. Hurricane return periods range from 5 yr in southern Florida to 105+ years at several sheltered portions of the coastline (e.g., near Cedar Key, Florida, Georgia, and the northeastern seaboard), where some locations experienced only one strike, or no strikes through the entire period of record. Severe hurricane (category 3–5) return periods range from once every 15 yr in South Florida to 105+ in New England.

Okra (Abelmoschus esculentus) is grown as a direct-seeded cash crop at high plant populations (>87,000 plants/acre) on calcareous soils in Homestead, south Florida. A study was established in a commercial field in May 2005 to evaluate if high populations translated to higher yields. Seedlings were thinned to within-row spacings of 2, 4, 6, 8, and 10 inches in rows set 3 ft apart (87120, 43560, 29040, 21780, and 17420 plants/acre). Harvest data was collected from 29 July to 30 Sept. 2005 (26 harvests) from 10 ft of the center row within plots 15 ft long and 3 rows wide. Decreasing plant density resulted in decreasing plant height early in the season and increasing height late in the season. Density affected stem caliper with a clear trend of decreasing density and increasing caliper. Early, mid-, and total yields by weight (boxes/acre) were not affected by density, but plants at the lowest density produced 55% more late yield than plants at the highest density. Plants at the lowest density produced 30% fewer early pods and 31% more late pods than plants at the highest density. Decreasing plant density resulted in increasing average pod weight for early, late, and total harvests by as much as 14% to 18%. With inexpensive open pollinated cultivars such as `Clemson Spineless 80', there seems little economic incentive to reduce plant populations below what is commonly used in the Homestead area. Growers should not be alarmed, however, if plant stands are reduced to some extent after seeding.

And Control

Napiergrass (Pennisetum purpureum Schumacher) is an enormous, weedy, cane-like grass (Figure 1) commonly seen growing along canals and roadsides in the sugarcane production area of south Florida. Napiergrass, also known as elephantgrass, has been documented in almost 30 counties throughout Florida. It is of African origin, but has been introduced to all tropical areas of the world because of its ability to quickly produce large amounts of biomass. Currently, napiergrass is widely used in Central America, South America, and Africa as a forage crop. Napiergrass was introduced to South Florida and Texas for use as a forage crop, but it is no longer widely used for this purpose and has become a major weed problem. Napiergrass is now established throughout southern Florida, especially along canal and ditch banks and in disturbed or cultivated areas. Because of the weedy characteristics of napiergrass, it is considered to be one of the world's worst weeds and has been listed as an invasive species by the Florida Exotic Pest Plant Council. Although it can be found in central and northern Florida, it is less common due to cooler temperatures. This document is SS-AGR-242, one of a series of the Agronomy Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Environmental variability exerts a substantial control on massive, free-living, colonial corals such as Manicina areolata, influencing their shape and size as well as other characters, such as base morphology and colline complexity in meandroid forms. This species is well adapted for life in shallow, wave-swept waters due to its self-righting capabilities. Two different ecophenotypes of M. areolata, as defined by overall shape and base morphology, are present in two approximately coeval Pleistocene localities (PBA Quarry and Holey Land Canal) in southern Florida. These differences reflect adaptation to two depositional settings. Corallum size, shape, and oral complexity allow clear differentiation between these two environments. Greater corallum size, as primarily manifested by significantly greater height, tends to accompany increased grain size. The basal area and weight per cm2 of the coralla appear to be primary limiting factors in M. areolata's growth by controlling the coral's ability to self-right after overturning or causing sinking into less cohesive substrates. Complexity of confluent corallites increases with increasing size and colony volume. Thus, complexity of valley and colline patterns on the oral surface increases as a function of base area, so that collines developed on smaller, soft-substrate-inhabiting colonies are characteristically less complex than are those of larger, higher colonies. These complexities and variation in shape are apparently related to environmental conditions, predominantly substrate, water depth, and physical energy, resulting in recognizable ecophenotypes.

In the quest to produce tomatoes without using methyl bromide, cover crops including sunnhemp, cowpea, hairy vetch, and sorghum sudan were planted on calcareous gravelly soils of southern Florida in Oct. 1998. These crops, singly or in mix, were grown on raised beds for 3 months before they were mowed down with no tillage. Sorghum sudan was plowed down and covered with plastic mulch, a conventional farming practice. In addition, uncropped plots fertilized with 6 N–2.6P–10K at 0 or 1124 kg·ha–1 were either treated with or without methyl bromide-chloropicrin and plowed down. `Sanibel' tomatoes (Lycopersicon esculentum Mill) were transplanted in two plant densities (one row vs. two rows on a bed) immediately after mowing. Tomatoes were fertigated with 112 N and 186 K kg·ha–1 during the growing season. Sunnhemp biomass alone or in mix with cowpea was higher than any other treatment. Biomass of sorghum sudan and hairy vetch were lowest. Canopy coverage, nutrient content of cover crops, and their effects on tomato growth, nutrient content, and yield will be discussed.

During a 2016 survey of the nematode associates of the native palmetto weevil,Rhynchophorus cruentatus, and the recently introduced West Indian sugarcane weevil,Metamasius hemipterus(Coleoptera: Curculionidae), from southern Florida, a new species ofAcrostichuswas cultured from a single dissectedR. cruentatusfrom Fort Pierce, FL, USA. Morphological and molecular studies showed that it was new to science and it is described herein asA. floridensisn. sp. The new species is characterised by its male tail characters, spicule morphology with rounded manubrium separated from other parts by clear constriction, smoothly ventrally curved blade, slightly dorsally recurved and pointed tip, more or less straight gubernaculum with widely rounded anterior end and a triangular (arrowhead-like) appendage at the distal tip, and the arrangement of male genital papillae, ⟨(v1, v2), v3 / v4, ad, ph, (v5, v6, v7, pd)⟩. In addition toA. floridensisn. sp. and the previously described nematode associates ofR. cruentatus,i.e.,A. rhynchophori,Teratorhabditis palmarumandMononchoidessp., we recovered a putative new species ofDemaniellaand a new association record withRhabditidoides humicolusandDiplogastrellus metamasiusin Homestead, FL. Dissections and subsequent culturing attempts withM. hemipterusrevealed the previously described nematode associates ofCaenorhabditis angariaandD. metamasiusas well as a new association withR. humicolusin Homestead, FL, USA.

The incidence of Citrus tristeza virus (CTV) was found to increase significantly in southern Florida within 2 years after the establishment of its most efficient vector, Toxoptera citricida (Kirkaldy). Increased incidence of both mild and severe strains was documented, with the incidence of severe strains increasing more than mild strains. Molecular probes capable of differentiating mild, quick decline and various types of stem-pitting strains demonstrated that trees often were infected with more than one strain of CTV, with trees containing up to five different strains. Some CTV strains detected in the southeast urban corridor of Florida and in commercial groves in southwest Florida were found to react with probes specific for stem-pitting strains known from elsewhere in the world. The implications of the presence of these CTV strains in Florida and their possible presence in citrus budwood scion trees are discussed.
