“…The two species E.orientalis and E.banksi are widely distributed over the world and have been reported from approximately 223 and 84 various host plants, respectively (Bolland et al 1998, Migeon and Dorkeld 2006–2017, Mattos and Feres 2009, Vacante 2010). Morphological variations in shape and length of dorsal setae, striation pattern between setae d1 and e1 and legs chaetotaxy have been reported in these two species (Baker and Pritchard 1960, Chaudhri et al 1974, Meyer 1974, Meyer 1987, Khanjani et al 2017).…”

Two new species of the genus Eutetranychus Banks are described and illustrated based on adult females and males, E.spinosussp. n. from Indigoferaspinosa Forssk (Leguminosae), E.neotransversussp. n. from Juniperusprocera Hochst. ex Endl. (Cupressaceae), and E.palmatus Attiah, 1967 is redescribed from Washingtoniarobusta H. Wendl. (Arecaceae). Additionally, the intraspecific morphological variations within E.orientalis populations, collected from 28 various host plants and 80 different localities from six regions of Saudi Arabia from 2009 to 2017, are discussed and presented. The genus Eutetranychus is divided into two species groups based on the presence of one seta (orientalis group) or two setae (banksi group) on coxa II. In addition, seven Eutetranychus species are suggested as synonyms of E.orientalis (Klein, 1936) and E.papayensis Iqbal & Ali, 2008 is considered as species inquirenda. A key to all known species of the genus Eutetranychus is provided.

“…1 a Female (left) and male (right) of Eutetranychus orientalis. b Precopulatory behavior: guarding male on a female teleiochrysalis demonstrated in E. banksi (Mattos and Feres 2009). Reliable characters for species identification include the pattern formed by the setae e1 and f1 on the dorsal surface and the number of ventral setae on the coxa of leg II.…”

“…In addition, coxa II has only one ventral seta in E. orientalis, but two setae in E. banksi (Fig. 4); E. orientalis has six setae on tibia III and seven on tibia IV, whereas in E. banksi tibia III bears 4-5 setae and tibia IV 5-6 setae (Smith-Meyer 1987; Mattos and Feres 2009). Fortunately, these differences can be observed in female specimens, making it unnecessary that males to be present, processed and slide mounted.…”

New mite invasions in citrus in the early years of the 21st century

2012

Several mite species commonly attack cultivated citrus around the world. Up to 104 phytophagous species have been reported causing damage to leaves, buds and fruits, but only a dozen can be considered major pests requiring control measures. In recent years, several species have expanded their geographical range primarily due to the great increase in trade and travel worldwide, representing a threat to agriculture in many countries. Three spider mite species (Acari: Tetranychidae) have recently invaded the citrus-growing areas in the Mediterranean region and Latin America. The Oriental red mite, Eutetranychus orientalis (Klein), presumably from the Near East, was detected in southern Spain in 2001. The Texas citrus mite, Eutetranychus banksi (McGregor), is widely distributed in North, Central and South America. It was first reported in Europe in 1999 on citrus in Portugal; afterwards the mite invaded the citrus orchards in southern Spain. In Latin America, the Hindustan citrus mite, Schizotetranychus hindustanicus (Hirst), previously known only from citrus and other host plants in India, was reported causing significant damage to citrus leaves and fruits in Zulia, northwest Venezuela, in the late 1990s. Later, this mite species spread to the southeast being detected on lemon trees in the state of Roraima in northern Brazil in 2008. Whereas damage levels, population dynamics and control measures are relatively well know in the case of Oriental red mite and Texas citrus mite, our knowledge of S. hindustanicus is noticeably scant. In the present paper, information on pest status, seasonal trends and natural enemies in invaded areas is provided for these species, together with morphological data useful for identification. Because invasive species may evolve during the invasion process, comparison of behavior, damage and management options between native and invaded areas for these species will be useful for understanding the invader's success and their ability to colonize new regions.

“…Las diferencias morfológicas encontradas entre las diferentes poblaciones de T. urticae y E. lewisi podrían estar relacionadas al efecto de la planta hospedante y localidad (Mattos y Feres 2009). Estos dos factores pueden llevar a la formación de razas como consecuencia del sistema de reproducción haplodiploide presente en Tetranychidae (Helle y Overmeer 1973).…”

Variación quetotáxica en poblaciones de Tetranychus urticae Koch, 1836 y Eotetranychus lewisi (Mc Gregor, 1943) (Acari: Tetranychidae) de diferentes cultivos y localidades en la Provincia de Tungurahua, Ecuador

Las especies de la familia Tetranychidae exhiben una amplia plasticidad fenotípica como respuesta a las variaciones ambientales, lo cual podría conducir a identificaciones erróneas dada la similitud morfológica entre algunas especies. En el presente trabajo se evaluaron las variaciones quetotáxicas de poblaciones de Tetranychus urticae Koch y Eotetranychus lewisi (McGregor) recolectadas en diferentes plantas hospedantes y localidades en seis cantones de la Provincia de Tungurahua, Ecuador. Se tomaron muestras de hojas de plantas de fresa, mora y zanahoria blanca que mostraban síntomas de alimentación por tetraníquidos en los cantones Ambato, Cevallos, Baños, Mocha, Píllaro y Tisaleo. En general, las sedas idiosomales presentaron una amplia variación debida a la planta hospedante y a la localidad de procedencia. El Análisis de Componentes Principales (ACP) logró explicar el 82% de la variación observada entre variables medidas sobre las 18 muestras, las cuales lograron separar a las poblaciones recolectadas sobre mora, independientemente de la especie de ácaro, mientras que las poblaciones recolectadas sobre zanahoria blanca y fresa no fueron claramente separadas. Las variables quetotáxicas mostraron la variación intra poblacional de T. urticae y E. lewisi por efecto de la planta hospedante, por lo que esto debería ser considerado al momento de la identificación de ambas especies.
