Gray, Assistant Entomologist Joe Schuh, Assistant in Entomology Don C. Mote, Head, Departmentof Entomology The potato flea-beetle, Epitrix cucumeris Harris,can be controlled by a well-executed dusting program. The information as to whatmaterial to use, when to apply it, and how much to use as based on experiments conductedto date will be found in the followingpages. Calcium Arsenate is MostEfficient Poison: A dust containing 20% calcium arsenate and 3% powderedsugar is suggested. The following is the mostconsistently efficient formula found: Calcium arsenate 20 pounds Powdered sugar 3 pounds iatomaceous earth 10 pounds Talc 67 pounds Insecticides other than calciumarsenate have given good results recommended because they but are not are more expensive and haveproven no more effective. Some of these are: roterione,cryolite, copper arsenate, green. sodium fluosilicate, and Paris Sprays containing calcium arsenate or the other aforementionedsubstances are as effective as the dusts containing these insecticides.They, however, are more expensive to apply because of the much greater cost ofspray machines and the time required in refilling thetank. Caution. Calcium arsenate is poisonousto man and animals as wellas flea- beet:les and for thatreason must be handled with ing. care to prevent accidental poison- Laboratory and field tests both indicate that hydratedlime is an inferior carrier for calcium arsenate when used to combatflea-beetles. Time of Applications is theMost Important Factor: 1. Potatoes Before 15 Do Not Require Dusting before 15 to 20.

  • Flea Beetles (Order: Coleoptera, Family: Chrysomelidae/Alticinae) Tobacco (Epitrix Hirtipennis (Melsheimer)) Southern Tobacco (
    Flea beetles (Order: Coleoptera, Family: Chrysomelidae/Alticinae) Tobacco (Epitrix hirtipennis (Melsheimer)) Southern tobacco (Epitrix fasciata (Blatchley)) Pale striped (Systena blanda (Melsheimer)) Description: Adult: The tobacco and southern tobacco flea beetle adults are small (1.4- 2.2 mm in length) and reddish, yellow brown, with a brown patch across the width of the elytra. The southern tobacco adult is slightly smaller and wider than the tobacco flea beetle. The pale striped flea beetle adult is larger (3.0- 4.3 mm long) and has a pair of pale yellow stripes lengthwise down the back, one stripe on each elytron. Immature stages: All of the above species have three larval instars that are whitish with darker heads, and all feed on fine roots near the soil surface or occasionally tunnel into larger roots. The tobacco flea beetle larvae range Tobacco flea beetle adult. from 1 mm after hatching to 4.2 mm at maturity, while the pale stripe larvae range from 1 to 11 mm. Biology: Life cycle: Tobacco flea beetle females can lay up to 200 eggs which hatch in 6- 8 days. The larval development typically lasts from 16-20 days under warm conditions. The last instar larva forms a small cell in the soil where it pupates, and the adult emerges 4-5 days later for a total of 26-33 days. The pale striped flea beetle requires a longer time to develop from egg to adult, 28-54 days total. Seasonal distribution: There are 3-4 generations of the tobacco flea beetles per year. High numbers have been observed in south Georgia in late June in Solanaceous crop transplants, and we think that this is likely a second generation.

  • Regional IPPC Workshops 2015 Surveillance: Working Together to Strengthen Implementation
    International Plant Protection Convention Surveillance: Working together to strengthen implementation Regional IPPC Workshops 2015 Surveillance: Working together to strengthen implementation The CPM agreed for an increased emphasis on surveillance in the next several years. This will take place through an Implementation Pilot Programme on Surveillance, which will be a coordinated effort with active participation from contracting parties and RPPOs. The Regional IPPC Workshops are an opportunity to share experiences with surveillance activities such as: current status, upcoming plans, and successes and challenges of surveillance activities within your country. In 2015, Member Countries answered a questionnaire on surveillance circulated by the IPPC Secretariat, and presented a summary on surveillance activities undertaken during the regional workshop. The data provided by Member Countries were extremely rich and useful to define activities to be set in the framework of the Implementation Pilot Programme on Surveillance. The content of the questionnaire for the regions in which an IPPC regional workshop was organized are provided below: Near East and North Africa, Pacific, Central Asia and Eastern Europe, Caribbean and Latin America (in Spanish). Surveillance: An official process which collects and records data on pest presence or absence by survey, monitoring or other procedures (ISPM 5) Question 1: What general surveillance activities take place in your country? (General surveillance is a process whereby information on particular pests which are of concern for an area is gathered from many sources, wherever it is available and provided for use by the NPPO – ISPM 6) 1.

  • Flea Beetles
    Problem: Flea Beetles Hosts: Watermelons, pumpkins, peas, beans, eggplants, sweet potatoes, beets, spinach, strawberries and potatoes. Description: "Flea beetle" is a generic name applied to many species of small jumping beetles commonly seen early in the gardening season. Some species are general feeders while others have a more restricted host range. All flea beetle life stages are completed underground. Only the adults are commonly seen by gardeners and vegetable producers. Flea beetles may be somewhat elongate to oval in shape, and vary in color, pattern, and size. For instance, potato flea beetles (Epitrix cucumeris) tend to be more oval, blackish, and about 1/16-inch long. Striped flea beetles (Phyllotreta striolata) are more elongate and dark with yellowish crooked stripes, and measure about 1/12-inch long. Spinach flea beetles (Disonycha xanthomelaena) are both oval and elongate. They have a black head, antennae and legs. The collar behind the head is yellow to yellowish-orange. Wing covers have blackish-blue luster. They approach 1/5 inch in body length. With most species of flea beetle, the adults overwinter underground or beneath plant debris. During April and May, they become active, mate, and deposit eggs. Egg laying varies depending upon species. Some deposit individual eggs while others deposit them in clusters. Egg sites may be in soil, on leaves, on leaf petioles, or within holes chewed into stems. Eggs typically hatch in 10 days. Larval and pupal development take place during the summer. "New" adults emerge and feed during late summer and fall before seeking overwintering sites. Larvae feeding on underground portions of plants may result in decreased plant vigor.

  • Inventory and Review of Quantitative Models for Spread of Plant Pests for Use in Pest Risk Assessment for the EU Territory1
    EFSA supporting publication 2015:EN-795 EXTERNAL SCIENTIFIC REPORT Inventory and review of quantitative models for spread of plant pests for use in pest risk assessment for the EU territory1 NERC Centre for Ecology and Hydrology 2 Maclean Building, Benson Lane, Crowmarsh Gifford, Wallingford, OX10 8BB, UK ABSTRACT This report considers the prospects for increasing the use of quantitative models for plant pest spread and dispersal in EFSA Plant Health risk assessments. The agreed major aims were to provide an overview of current modelling approaches and their strengths and weaknesses for risk assessment, and to develop and test a system for risk assessors to select appropriate models for application. First, we conducted an extensive literature review, based on protocols developed for systematic reviews. The review located 468 models for plant pest spread and dispersal and these were entered into a searchable and secure Electronic Model Inventory database. A cluster analysis on how these models were formulated allowed us to identify eight distinct major modelling strategies that were differentiated by the types of pests they were used for and the ways in which they were parameterised and analysed. These strategies varied in their strengths and weaknesses, meaning that no single approach was the most useful for all elements of risk assessment. Therefore we developed a Decision Support Scheme (DSS) to guide model selection. The DSS identifies the most appropriate strategies by weighing up the goals of risk assessment and constraints imposed by lack of data or expertise. Searching and filtering the Electronic Model Inventory then allows the assessor to locate specific models within those strategies that can be applied.

[email protected]. RESUMEN. El Psilido Asiático de los Cítricos actualmente es la principal plaga de la citricultura en el mundo por ser vector de la bacteria Candidatus liberobacter que ocasiona el Huanglongbing. Tanto adultos como ninfas de cuarto y quinto instar pueden ser vectores de esta enfermedad por lo que su control es básico para minimizar este problema. Se realizó esta investigación para conocer el comportamiento de los estados inmaduros de la plaga a varias alternativas químicas de control. El análisis de los datos de mortalidad muestra que las poblaciones de Diaphorina tratadas con: clorpirifós, dimetoato, clotianidin, dinotefurán, thiametoxan, endosulfán, imidacloprid, lambdacialotrina, zetacipermetrina, y lambdacialotrina registraron mortalidades superiores al 85%. Por otra parte, las poblaciones tratadas con: pymetrozine (pyridine azomethines) y spirotetramat (regulador de crecimiento de la síntesis de lípidos) a las dosis evaluadas no presentaron efecto tóxico por contacto o efecto fumigante sobre la población antes mencionada. Palabras Clave: psílido, Diaphorina citri, ninfas, insecticidas. ABSTRACT. The Asian Citrus Psyllid, vector of Candidatus Liberobacter, bacteria that causes Huanglongbing disease, is currently the major pest of citrus in the world. Both, adults and nymphs of fourth and fifth instar can be vectors this pathogen, and therefore their control is essential to prevent increase and spread of disease. This research was carried out to evaluate the biological response of the immature stages of the pest to several chemical alternatives.
