“…Within the pest categorisation of E. lewisi (EFSA PLH Panel, 2014a), the Panel provided a list of 69 plants species on which E. lewisi had been reported. The Panel indicated that the report of the mite on a plant did not mean that the plant was a true host, i.e.…”

“…95% of the uncertainty in the estimate of the number of E. lewisi founder population establishing outdoors in the EU is related to the number of E. lewisi 'escapes' from infested glasshouses. The Panel recognises that E. lewisi has been found on poinsettia in EU glasshouses on a number of occasions (EFSA, 2014a;EPPO, 2014) but was eradicated on each occasion. E. lewisi is not known to occur outdoors within continental EU.…”

Following the 2014 EFSA's Panel on Plant Health scientific opinion on the pest categorisation of the spider mite Eotetranychus lewisi, the European Commission requested the Panel to perform a pest risk assessment and evaluate the risk reduction options. A stochastic model was used to assess entry, establishment and spread and related uncertainties. In the EU, E. lewisi has only been reported to occur in Portugal (Madeira). Entry pathways assessed were strawberry plants for planting from the USA, poinsettia and raspberry plants for planting, and orange and lemon fruits from third countries. Entry is most likely via poinsettia. Under current EU phytosanitary requirements, there is around a one in ten chance that E. lewisi will establish outdoors over the next 10 years. Although unlikely, establishment would most likely occur in southern Europe where environmental conditions, temperature and host density, are most suitable. If E. lewisi did establish, pest spread is expected to be mainly human assisted, most likely the mite being transported long distances on plants for planting. Nevertheless, while remaining a regulated pest, spread would be slow and most likely confined to one NUTS 2 area after 10 years. Under a scenario with enhanced measures (pest free place of production) at origin, the Panel's assessment indicate that it is extremely unlikely that E. lewisi would establish within 10 years hence spread is also extremely unlikely. The absence of trade of host plants from Madeira to other parts of the EU could explain why E. lewisi has not spread to other EU Member States. E. lewisi is reported as reducing yield and quality of peaches and poinsettia and is regarded as a growing concern for strawberry and raspberry growers in the Americas. The Panel concludes that should E. lewisi be introduced in the EU similar impacts could be expected.

En el cultivo de papayo (Carica papaya L., 1753), los ácaros fitófagos se han incrementado como resultado de un desbalance en las poblaciones por el uso excesivo de plaguicidas. Dentro de los programas de manejo integrado de plagas, es importante conocer los factores que afectan la densidad poblacional de éstas. Por ello se buscó determinar la correlación espacio-temporal de ácaros fitófagos y depredadores en el cultivo de papayo en Manlio F. Altamirano, Veracruz, México. Se utilizó una huerta con manejo convencional, que incluyó la aplicación de fertilizantes y plaguicidas. Se realizaron muestreos de los ácaros en hojas colectadas en los estratos alto, medio y bajo de cada planta, una por estrato, en un total de 20 plantas. Se realizaron nueve muestreos de mayo 2007 a septiembre 2008. Eoetranychus lewisi (McGregor,1943) fue la especie más abundante en los tres estratos, seguida de Eutetranychus banksi (McGregor, 1914), que tuvo sus mayores poblaciones en los estratos bajo y medio. Se encontró a Euseius hibisci (Chant, 1959), ácaro depredador generalista, y a Galendromus helveolus (Chant, 1959), ácaro depredador especializado en alimentarse de tetraníquidos. Se presentaron dos picos poblacionales sincrónicos entre los grupos de especies de ácaros fitófagos y depredadores. Se mostraron correlaciones positivas (r2 de 0.5 a 0.6) entre las poblaciones de ácaros fitófagos y depredadores. Temperaturas medias superiores a 30 °C y lluvia mensual acumulada superior a 200 mm abatieron las poblaciones de E. banksi. Se recomienda iniciar el muestreo de ácaros desde dos meses después del trasplante, ya que en la zona Centro del estado de Veracruz existen condiciones ambientales favorables para su desarrollo.

Scientific Opinion on the pest categorisation ofEotetranychus lewisi

Abstract: The Panel on Plant Health performed a pest categorisation of the Lewis spider mite, Eotetranychus lewisi, for the European Union (EU). The Lewis spider mite is a well-defined and distinguishable pest species that has been reported from a wide range of hosts, including cultivated species.
