Observações Sobre a Ocorrência De Mosca-Negra- Dos-Citros, Aleurocanthus Woglumi Ashby, 1915 (Hemiptera: Sternorrhyncha: Aleyrodidae) No Estado Do Amazonas
Observações sobre a ocorrência de Mosca-Negra- dos-Citros, Aleurocanthus woglumi Ashby, 1915 (Hemiptera: Sternorrhyncha: Aleyrodidae) no estado do Amazonas Beatriz RONCHI-TELES1, Marcia Reis PENA2, Neliton Marques SILVA3 RESUMO A mosca-negra-dos-citros (Aleurocanthus woglumi Ashby) é uma importante praga dos citros de origem asiática. Foi detectada no Brasil pela primeira vez em Belém-PA em 2001. Este trabalho tem como objetivo registrar a ocorrência de mosca-negra-dos- citros no estado do Amazonas, sua distribuição geográfica e estudos de biologia em condições de laboratório. A mosca-negra encontra-se atualmente disseminada em mais da metade dos municípios paraenses. No Amazonas foi detectada em junho de 2004 em Manaus e atualmente encontra-se disseminada em toda a área urbana deste município, ocorrendo também em Itacoatiara, Rio Preto da Eva e Iranduba. Em observações feitas em condições de laboratório em Manaus-AM, foi verificado que o ciclo de ovo-adulto foi de 71,76±2,07 dias, caracterizando como uma espécie multivoltina. PALAVRAS-CHAVE: Amazônia, Praga dos citros, Distribuição, Aleirodídeo. Observation on the occurrence of the citrus blackfly Aleurocanthus woglumi Ashby, 1915 (Hemiptera: Sternorrhyncha: Aleyrodidae) in the Amazonas state ABSTRACT The citrus blackflyAleurocanthus woglumi Ashby, pest of citrus in Asian is considered important pest. It was detected for the first time in Belém, PA in 2001. The objective of this work was to report occurrence of the citrus blackfly in Amazon state. Nowadays is found in the majority of the oriental amazon counties. In Manaus, Amazonas was detected in June 2004, actually disseminated in the urban area and in Itacoatiara, Rio Preto da Eva and Iranduba counties. -

Abstract Four species of plant parasitic nematodes were present in soil samples planted with forage legumes at Alachua County, Florida, USA. The detected species Belonolaimus longicaudatus, Criconemella ornate, Hoplolaimus galeatus, and Paratrichodorus minor were described in the present study. They belong to orders Rhabditida (Belonolaimus longicaudatus, Criconemella ornate, and Hoplolaimus galeatus) and Triplonchida (Paratrichodorus minor) and to taxonomical families Dolichodoridae (Belonolaimus longicaudatus), Hoplolaimidae (Hoplolaimus galeatus) Criconematidae (Criconemella ornate), and Trichodoridae (Paratrichodorus minor). The identification of the present specimens was based on the classical taxonomy, following morphological and morphometrical characters in the species specific identification keys.

Population Dynamics of Tomato Russet Mite, Aculops Lycopersici (Massee) and Its Natural Enemy, Homeopronematus Anconai (Baker)
JARQ 38 (3), 161 – 166 (2004) http://www.jircas.affrc.go.jp REVIEW Population Dynamics of Tomato Russet Mite, Aculops lycopersici (Massee) and Its Natural Enemy, Homeopronematus anconai (Baker) Akira KAWAI1* and Mohd. Mainul HAQUE2 Department of Fruit Vegetables, National Institute of Vegetables and Tea Science (Ano, Mie 514–2392, Japan) Abstract Developmental rates of Aculops lycopersici increased linearly as rearing temperature increased. A total of 81.2 degree-days above a developmental zero of 10.5°C were required to complete develop- ment from egg to adult emergence. Adult longevity decreased with increasing temperature. The high- est intrinsic rate of natural increase was observed at 25°C as 0.253 per day. The population increased exponentially on greenhouse tomato plants and the intrinsic rate of natural increase was estimated to be 0.175 per day. A. lycopersici first reproduced on the released leaves then moved upward. The infesta- tion caused great injury to the plants, with a large number of leaves turning brown and then drying up. The number of leaves, the plant height and the diameter of the main stem of the plants all decreased. Homeopronematus anconai naturally occurred on tomato plants. After the rapid population increase of H. anconai, the A. lycopersici population decreased sharply. An adult H. anconai consumed an aver- age of 69.3 A. lycopersici deutonymphs per day in the laboratory. H. anconai was thought to be a pro- spective natural enemy of A. lycopersici.

The following catalogue of the Iranian fauna of Aphelinidae includes a list of all genera and species recorded for the country, their distribution in and outside Iran, and known hosts in Iran. In total 138 species from 11 genera (Ablerus, Aphelinus, Aphytis, Coccobius, Coccophagoides, Coccophagus, Encarsia, Eretmocerus, Marietta, Myiocnema, Pteroptrix) are listed as the fauna of Iran.

Jordan Beans RA RMO Dir
Importation of Fresh Beans (Phaseolus vulgaris L.), Shelled or in Pods, from Jordan into the Continental United States A Qualitative, Pathway-Initiated Risk Assessment February 14, 2011 Version 2 Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology United States Department of Agriculture Animal and Plant Health Inspection Service Plant Protection and Quarantine 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Pest Risk Assessment for Beans from Jordan Executive Summary In this risk assessment we examined the risks associated with the importation of fresh beans (Phaseolus vulgaris L.), in pods (French, green, snap, and string beans) or shelled, from the Kingdom of Jordan into the continental United States. We developed a list of pests associated with beans (in any country) that occur in Jordan on any host based on scientific literature, previous commodity risk assessments, records of intercepted pests at ports-of-entry, and information from experts on bean production. This is a qualitative risk assessment, as we express estimates of risk in descriptive terms (High, Medium, and Low) rather than numerically in probabilities or frequencies. We identified seven quarantine pests likely to follow the pathway of introduction. We estimated Consequences of Introduction by assessing five elements that reflect the biology and ecology of the pests: climate-host interaction, host range, dispersal potential, economic impact, and environmental impact. We estimated Likelihood of Introduction values by considering both the quantity of the commodity imported annually and the potential for pest introduction and establishment. We summed the Consequences of Introduction and Likelihood of Introduction values to estimate overall Pest Risk Potentials, which describe risk in the absence of mitigation. -

Report and Recommendations on Cycad Aulacaspis Scale, Aulacaspis Yasumatsui Takagi (Hemiptera: Diaspididae)
IUCN/SSC Cycad Specialist Group – Subgroup on Invasive Pests Report and Recommendations on Cycad Aulacaspis Scale, Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae) 18 September 2005 Subgroup Members (Affiliated Institution & Location) • William Tang, Subgroup Leader (USDA-APHIS-PPQ, Miami, FL, USA) • Dr. John Donaldson, CSG Chair (South African National Biodiversity Institute & Kirstenbosch National Botanical Garden, Cape Town, South Africa) • Jody Haynes (Montgomery Botanical Center, Miami, FL, USA)1 • Dr. Irene Terry (Department of Biology, University of Utah, Salt Lake City, UT, USA) Consultants • Dr. Anne Brooke (Guam National Wildlife Refuge, Dededo, Guam) • Michael Davenport (Fairchild Tropical Botanic Garden, Miami, FL, USA) • Dr. Thomas Marler (College of Natural & Applied Sciences - AES, University of Guam, Mangilao, Guam) • Christine Wiese (Montgomery Botanical Center, Miami, FL, USA) Introduction The IUCN/SSC Cycad Specialist Group – Subgroup on Invasive Pests was formed in June 2005 to address the emerging threat to wild cycad populations from the artificial spread of insect pests and pathogens of cycads. Recently, an aggressive pest on cycads, the cycad aulacaspis scale (CAS)— Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae)—has spread through human activity and commerce to the point where two species of cycads face imminent extinction in the wild. Given its mission of cycad conservation, we believe the CSG should clearly focus its attention on mitigating the impact of CAS on wild cycad populations and cultivated cycad collections of conservation importance (e.g., Montgomery Botanical Center). The control of CAS in home gardens, commercial nurseries, and city landscapes is outside the scope of this report and is a topic covered in various online resources (see www.montgomerybotanical.org/Pages/CASlinks.htm). -
