SCIENTIFIC OPINION ADOPTED: 27 September 2018 doi: 10.2903/j.efsa.2018.5436 Pest categorisation of Aleurocanthus spp. EFSA Panel on Plant Health (PLH), Claude Bragard, Katharina Dehnen-Schmutz, Francesco Di Serio, Paolo Gonthier, Marie-Agnes Jacques, Josep Anton Jaques Miret, Annemarie Fejer Justesen, Christer Sven Magnusson, Panagiotis Milonas, Juan A Navas-Cortes, Stephen Parnell, Roel Potting, Philippe Lucien Reignault, Hans-Hermann Thulke, Wopke Van der Werf, Antonio Vicent Civera, Jonathan Yuen, Lucia Zappala, Maria Navajas Navarro, Virag Kertesz, Ewelina Czwienczek and Alan MacLeod Abstract The Panel on Plant Health performed a pest categorisation of Aleurocanthus spp., a well-defined insect genus of the whitefly family Aleyrodidae (Arthropoda: Hemiptera). Difficulties within the taxonomy of the genus give doubt about the ability to accurately identify some members to species level. Nevertheless, the genus is thought to currently include about ninety species mainly reported from tropical and subtropical areas. The genus is listed in Council Directive 2000/29/EC and is regulated on Citrus, Fortunella and Poncirus. Several Aleurocanthus species are highly polyphagous; Aleurocanthus spiniferus has hosts in 38 plant families; Aleurocanthus woglumi has more than 300 hosts including Pyrus, Rosa and Vitis vinifera as well as Citrus. A. spiniferus is present in the EU in restricted areas of Italy and Greece, where it is under official control. No other Aleurocanthus spp. are known to occur in the EU. Host plants for planting, excluding seeds, and cut flowers or branches are the main pathways for entry. Outside of the EU, the genus can be found in regions that have climate types which also occur within the EU, suggesting establishment is possible. Aleurocanthus spp. can be significant pests of crops that are also grown in the EU. Phytosanitary measures are available to reduce the likelihood of entry into the EU, e.g. sourcing host plants for planting from pest free areas. As a genus Aleurocanthus does satisfy all the criteria that are within the remit of EFSA to assess and required by risk managers to give it consideration as a Union quarantine pest. Aleurocanthus does not meet all of the criteria to allow it consideration by risk managers as a Union regulated non-quarantine pest (RNQP). Specifically, Aleurocanthus is not widespread in the EU. © 2018 European Food Safety Authority. EFSA Journal published by John Wiley and Sons Ltd on behalf of European Food Safety Authority.

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.

EENY-170 Ladybirds, Ladybird beetles, Lady Beetles, Ladybugs of Florida, Coleoptera: Coccinellidae1 J. H. Frank R. F. Mizell, III2 Introduction Ladybird is a name that has been used in England for more than 600 years for the European beetle Coccinella septempunctata. As knowledge about insects increased, the name became extended to all its relatives, members of the beetle family Coccinellidae. Of course these insects are not birds, but butterflies are not flies, nor are dragonflies, stoneflies, mayflies, and fireflies, which all are true common names in folklore, not invented names. The lady for whom they were named was "the Virgin Mary," and common names in other European languages have the same association (the German name Marienkafer translates Figure 1. Adult Coccinella septempunctata Linnaeus, the to "Marybeetle" or ladybeetle). Prose and poetry sevenspotted lady beetle.

Coccinella septempunctata. We can but hope that newspaper writers will desist from generalizing them In the USA, the name ladybird was popularly all as "the ladybird" and thus deluding the public into americanized to ladybug, although these insects are believing that there is only one species. There are beetles (Coleoptera), not bugs (Hemiptera). many species of ladybirds, just as there are of birds, and the word "variety" (frequently use by newspaper 1.

R. pomonella est une mouche de la famille des Tephritidae (espèces non européennes). Cette famille contient de nombreuses espèces, parmi lesquelles certaines sont des organismes nuisibles importants. En particulier, le genre Rhagoletis contient 77 espèces qui sont répandues en Asie et Amérique. Lorsque la culture de pommier a été introduite en Amérique du Nord au milieu du 19ième siècle, R. pomonella s’est déplacée de sa plante-hôte naturelle Crataegus (aubépine) vers les fruits du pommier domestique, ce qui a permis la dissémination de cette mouche sur tout le continent nord- américain (Canada, Etats-Unis, Mexique). Actuellement, R. pomonella est le plus grave des ravageurs parmi les mouches des fruits en Amérique du Nord.

The pathogenicity of the 30 isolates was determined by the mortality that they caused in larvae and adults and it was expressed in percentage; for this, a complete randomized design (CRD) was used.
