Palm weevils have been reported as a pest and red ring nematode vectors for several palms of the Arecaceae family. Rhynchophorus palmarum L (Coleoptera: Curculionidae) is a pest for coconut crop and other palms. It is vector of Bursaphelenchus cocophilus (Cobb) Baujard (Nematoda) etiological agent of Red Ring disease and other nematodes. Current methods recommended use of enemies and parasites in integrated pest management of Rhynchophorinae. In addition, mass trap reduce environmental damage. The objectives of our study on coconut plantations were: (1) to determine the efficiency of low expensive kariomones traps and (2) low expensive kariomones and pheromones traps using adult males; and (3) to examine R. palmarum using light and scanning electron microscopy searching for ectoparasites which can be proposed in integrated pest management.

  • Giant Palm Weevils of the Genus Rhynchophorus (Coleoptera: Curculionidae) and Their Threat to Florida Palms
    DACS-P-01719 Pest Alert created 18-February-2010 Florida Department of Agriculture and Consumer Services, Division of Plant Industry Adam H. Putnam, Commissioner of Agriculture Giant Palm Weevils of the Genus Rhynchophorus (Coleoptera: Curculionidae) and Their Threat to Florida Palms Michael C. Thomas, Taxonomic Entomologist, Florida Department of Agriculture and Consumer Services, Division of Plant Industry INTRODUCTION: The giant palm weevils of the genus Rhynchophorus Herbst are among the worst palm pests in the world. One species, Rhynchophorus cruentatus (Fabricius), is native to Florida and the southeastern US. Two other species, Rhynchophorus ferrugineus (Olivier) and Rhynchophorus palmarum (L.), are found in the New World and are considered to be threats to palms in Florida. Of particular concern is R. ferrugineus, known as the red palm weevil. It is a pest of coconut and other palms in its native range. Over the past three decades, its range has expanded into the Middle East, North Africa and Mediterranean Europe. It attacks many palm species, but is especially devastating on date palms. It recently became established in Curaçao in the Caribbean, placing it ever closer to Florida. In each case, it is suspected that the weevils travelled with imported palms. In January 2010, the federal government prohibited the importation into the United States of live palms belonging to 17 genera. IDENTIFICATION: Identification of adult palm weevils is straightforward as they are the largest weevils in NorthAmerica, ranging from about 1 to 1.8 inches (25mm to 45mm) in length. The individual species are rather similar, but the three species under consideration can be distinguished by the following key: 1.

    EXHIBIT I Management Procedures for Archaeological and Historical Sites and Properties on State-Owned or Controlled Lands Management Procedures for Archaeological and Historical Sites and Properties on State-Owned or Controlled Properties (revised February 2007) These procedures apply to state agencies, local governments, and non-profits that manage state- owned properties. A. General Discussion Historic resources are both archaeological sites and historic structures. Per Chapter 267, Florida Statutes, ‘Historic property’ or ‘historic resource’ means any prehistoric district, site, building, object, or other real or personal property of historical, architectural, or archaeological value, and folklife resources. These properties or resources may include, but are not limited to, monuments, memorials, Indian habitations, ceremonial sites, abandoned settlements, sunken or abandoned ships, engineering works, treasure trove, artifacts, or other objects with intrinsic historical or archaeological value, or any part thereof, relating to the history, government, and culture of the state.” B. Agency Responsibilities Per State Policy relative to historic properties, state agencies of the executive branch must allow the Division of Historical Resources (Division) the opportunity to comment on any undertakings, whether these undertakings directly involve the state agency, i.e., land management responsibilities, or the state agency has indirect jurisdiction, i.e. permitting authority, grants, etc. No state funds should be expended on the undertaking until the Division has the opportunity to review and comment on the project, permit, grant, etc. State agencies shall preserve the historic resources which are owned or controlled by the agency. Regarding proposed demolition or substantial alterations of historic properties, consultation with the Division must occur, and alternatives to demolition must be considered.

We propose a method for seed shape quantification based on the comparison of the bi-dimensional images of the seeds with geometric figures. J index is the percent of similarity of a seed image with a figure taken as a model. Models in shape quantification include geometrical figures (circle, ellipse, oval ::: ) and their derivatives, as well as other figures obtained as geometric representations of algebraic equations. The analysis is based on three sources: Published work, images available on the Internet, and seeds collected or stored in our collections. Some of the models here described are applied for the first time in seed morphology, like the superellipses, a group of bidimensional figures that represent well seed shape in species of the Calamoideae and Phoenix canariensis Hort. ex Chabaud.
