“…Discovered in Maryland in 1998, A. anthocoptes is now known to be present in 29 counties and in 7 states in the USA (Ochoa et al 2001). Aceria anthocoptes is the only eriophyid mite that has been recorded on C. arvense (Petanovic´et al 1997).…”

“…Aceria anthocoptes is the only eriophyid mite that has been recorded on C. arvense (Petanovic´et al 1997). With its apparent host specificity and because of the damage it causes on its host plant, A. anthocoptes is being studied as a potential candidate for the biological control of C. arvense (Ochoa et al 2001;Gassmann et al 2004). Aceria anthocoptes belongs to the group of free-living eriophyids, and is referred to as a vagrant species because of its life history and its morphology.…”

“…As mite density on the host plant increases, feeding activity induces changes in leaf colour, which becomes light brown and prevents the development of the inflorescence capitula. On very young plants the leaves become curled and the whole plant is distorted (Petanovic´et al 1997;Ochoa et al 2001). In addition to the above typical symptoms, a condition known as multiple flower-head disease had always been attributed to the presence of A. anthocoptes since its first record in 1892 (Nalepa 1892).…”

Anatomical Injury Induced by the Eriophyid Mite Aceria anthocoptes on the Leaves of Cirsium arvense

et al. 2006

Anatomical injury of the leaves of the invasive species, Cirsium arvense (L.) Scop., caused by the eriophyid mite Aceria anthocoptes (Nal.), which is the only eriophyid mite that has been recorded on C. arvense worldwide, is described. The injury induced by the mite feeding on the leaves of C. arvense results in visible russeting and bronzing of the leaves. Other conspicuous deformations are folding and distortion of the leaf blade and curling of leaf edge, as well as gradual drying of leaves. The anatomical injury of the mature leaves of field-collected plants was limited to the epidermis of the lower leaf surface. However, on young leaves of experimentally infested plants, rust mite injuries extend to epidermal cells on both leaf surfaces and to those of deeper mesophyll layers. On these leaves, lesions on the lower leaf surface even affected the phloem of the vascular bundles. Leaf damage induced by A. anthocoptes is discussed with regard to the mite's potential as a biological control agent of C. arvense.

“…Low temperature -SEM (LT-SEM) methods have been used in other studies, which have demonstrated excellent results on soft-bodied arthropods including mites (Achor et al, 2001;ARS-USDA, 2007;Erbe, Wergin, Ochoa, Dickens & Moser, 2001;Ochoa et al, 2001;Wergin et al, 2000;Dowling, Bauchan, Ochoa & Beard, 2010;Beard et al, 2012). Unfortunately, these methods require very specialized equipment attached to the SEM unit that is not available in Central America, which is why we only evaluated and discussed some techniques used for a standard SEM.…”

“…Different SEM techniques have been used for the observation and analysis of surface structures, providing important information about the relief, texture, size and shape, both on biological and mineral samples (Postek, Howard, Johnson & McMichael, 1980). The electron microscope has been used during the last 30 years, as a tool to facilitate morphological descriptions of mites and as a complement of information obtained under the light microscope (Keirans, Clifford & Corwin, 1976;Wergin, Ochoa, Erbe, Craemer & Raina, 2000;Achor et al, 2001;Ochoa, Erbe, Wergin, Frye & Lydon, 2001;Mariana, Santana, Ho, Tan & Zuhaizam, 2008;Kucerova & Stejskal, 2009). Thus, it is possible to better observe the shape and position of the various morphological features of the species.…”

Scanning electron microscopy (SEM) has been used as a tool to facilitate the morphological description of mites and to complement the information obtained from the light microscope. Unfortunately, several of SEM techniques used for soft-bodied mites such as Tyrophagus, have in many cases not shown the desired results. This investigation sought to develop an efficient procedure for preparing specimens of T. putrescentiae for SEM so that its major morphological characters could be observed and photographed. This species is the most important contaminant of tissue culture laboratories in Costa Rica. Seven methods were used to process the samples. The evaluated treatments showed differences in their ability to preserve the morphological structures of the specimens. The advantages and disadvantages of each treatment are discussed. Mites processed using ethanol were the most viable option with method 3 being the procedure that showed the best results; this technique also reduced the time and costs of processing the specimens. KEY WORDSAcari, Acaridae, Tyrophagus putrescentiae, Scanning Electron Microscopy (SEM), SEM techniques RESUMEN El microscopio electrónico de barrido (MEB) ha sido utilizado como una herramienta para complementar la información obtenida bajo el microscopio de luz. Desafortunadamente, muchas de las técnicas utilizadas con el MEB para ácaros de cuerpo suave como Tyrophagus, no han mostrado los resultados deseados en muchos casos. El presente trabajo buscó un procedimiento eficiente para observar y fotografiar bajo MEB los caracteres morfológicos más importantes de T. putrescentiae. Esta especie es el principal contaminante en cultivo de tejidos vegetales en Costa Rica. Se utilizaron siete tratamientos para el procesamiento de las muestras. Los tratamientos evaluados mostraron diferencias entre sí con respecto a la preservación de las estructuras de los especímenes. Se discuten las ventajas y desventajas de cada procedimiento. Los tratamientos con etanol fueron la opción más viable para procesar estos ácaros, siendo el tratamiento 3 el que mostró mejores resultados. Asimismo, esta técnica permite reducir tanto el tiempo como los costos durante el procesamiento de los especímenes.

Eriophyoid Mites: Progress and Prognoses

View full text Add to dashboard Cite

Eriophyoids have high potential as adventive mite species (AMS) because their small size make them difficult to detect, and can be easily distributed in world trade. Economic, social and environmental impact from adventive eriophyoid mites has been significant. Considerable attention has been given to adventive insect species while adventive mites have received little attention and little information is available for eriophyoids. This paper summarizes information on adventive eriophyoid mites, their impact, and the history of some important invasions. The status of adventive species of eriophyoids introduced as biological control agents of weeds is presented. A list of eriophyoid mites reported as invasive species worldwide is given. Pathways of concern and biosecurity actions to reduce the risk of eriophyoid mites are discussed. The need to raise public awareness of the risk and importance of these tiny organisms as AMS is emphasized. Scientific and technical challenges to deal with adventive eriophyoids are discussed.
