“…Unpromising results were obtained in a brief evaluation of an unidentifi ed Asca species as a predator of T. urticae Koch and Tetranychus evansi Baker and Pritchard as prey (Rosa et al 2005 ). However, Walter et al ( 1993 ) reported Asca species to be involved in the natural control of eriophyoid and tenuipalpid mites in tropical areas of Australia.…”

“…Among the factors that might account for different mite densities in the native and invaded areas is competition with other tetranychid species, which are abundant on solanaceous plants in Brazil [32 and 17 tetranychid species have been reported from solanaceous plants in South America and Europe, respectively (Migeon and Dorkeld 2006)]. In addition, effective native natural enemies in South America maintain T. evansi populations at low densities (Furtado et al 2005;Furtado et al 2006;Rosa et al 2005). For example the neotropical predatory mite Phytoseiulus longipes has been described as successfully developing on T. evansi (Maxime Ferrero, personal communication; Furtado et al 2007), and several other mite predators of the family Phytoseiidae have been reported associated with T. evansi on tomato and wild solanaceous plants in Brazil (Fiaboe et al 2006;Furtado et al 2006;Rosa et al 2005).…”

A fungal pathogen was also suggested as the causative agent of the decline of T. evansi populations in northeastern Brazil, when in 1979 occasional outbreaks in tomato field crops were reported (Humber et al 1981).…”

Recent emergence and worldwide spread of the red tomato spider mite, Tetranychus evansi: genetic variation and multiple cryptic invasions

et al. 2010

Plant biosecurity is increasingly challenged by emerging crop pests. The spider mite Tetranychus evansi has recently emerged as a new threat to solanaceous crops in Africa and the Mediterranean basin, with invasions characterized by a high reproductive output and an ability to withstand a wide range of temperatures. Mitochondrial (868 bp of COI) and nuclear (1,137 bp of ITS) loci were analyzed in T. evansi samples spanning the current geographical distribution to study the earliest stages of the invasive process. The two sets of markers separate the samples into two main clades that are only present together in South America and Southern Europe. The highest COI diversity was found in South America, consistent with the hypothesis of a South American origin of T. evansi. Among the invaded areas, the Mediterranean region displayed a high level of genetic diversity similar to that present in South America, that is likely the result of multiple colonization events. The invasions of Africa and Asia by T. evansi are characterized by a low genetic variation associated with distinct introductions. Genetic data demonstrate two different patterns of invasions: (1) populations in the Mediterranean basin that are a result of multiple cryptic introductions and (2) emerging invasions of Africa and Asia, each likely the result of propagules from one or limited sources. The recent invasions of T. evansi illustrate not only the importance of human activities in the spread of agricultural pests, but also the limits of international quarantine procedures, particularly for cryptic invasions.

“…Outro fato importante é que os ácaros possuem enorme capacidade de aumento populacional, chegando a 25 gerações por ano (MARUYAMA et al, 2002); portanto, para efeito de amostragem, a rapidez e a precisão na obtenção da informação deve ser levada em conta, já que atualmente o principal método de controle ainda é o químico (BRITO et al, 2006;EIDISATO et al, 2007;MARTÍNEZ-VILLAR, 2005;MOURÃO et al, 2004;ROSA et al, 2005), e uma demora na tomada de decisão para o controle poderá provocar danos inaceitáveis.…”

Resumo -Os ácaros do gênero Tetranychidae estão entre os principais artrópodes-pragas da cultura do algodoeiro. A ocorrência dessas pragas nessa malvácea pode ocasionar perdas no rendimento da cultura, inclusive pelo aumento nos custos de controle, o que pode implicar impactos no meio-ambiente e na saúde dos aplicadores de defensivos. Objetivou-se com esta pesquisa verificar a identidade taxonômica de um ácaro-vermelho, definir uma metodologia para a avaliação desse artrópode e definir uma unidade amostral para o ácaro no algodoeiro. O estudo foi realizado no Departamento de Fitotecnia da Universidade Federal do Ceará, Fortaleza, Brasil. A cultivar de algodoeiro utilizada foi a CNPA-2H. Inicialmente, a espécie de acarino foi coletada, posta em solução de álcool a 70% e enviada para identificação. Posteriormente, procurou-se validar uma metodologia pela qual os avaliadores utilizavam uma escala de notas. Em seguida, procedeu-se ao estudo da distribuição vertical do ácaro-vermelho em algodoeiro, para se definir uma unidade amostral para o ácaro. O delineamento utilizado foi o inteiramente casualizado em esquema fatorial 3x8, com 10 repetições. Para análise, os valores de notas foram transformados para grau de infestação. A espécie de ácaro-vermelho identificada foi Tetranychus aff. yusti McGregor. Verificou-se que a metodologia adotada permitiu discriminar a infestação do ácaro-vermelho em algodoeiro, e a unidade amostral para a referida praga foi a quarta folha a partir do ápice. Palavras-chave -Acari. Tetranychidae. Gossypium hirsutum.Abstract -The spider mites in the genus Tetranychidae are among the main arthropod pests of cotton. The occurrence of these pests in this malvaceae may cause yield reduction, increase of control costs, and also impact in the environment and on applicators health. The aim of this study was to verify the taxonomic identity of a red spider mite; define a sampling method for this arthropod and a sampling unit for the spider mite on cotton. This study was done in an area belonging to the Agronomy Department of the Federal University of Ceará, Fortaleza, Brazil. The CNPA-2H cotton cultivar was used. Initially, the spider mite was collected for identification, stored in a 70% alcohol solution and send for identification. Later on, the sampling method was tested in which the scouts used a score scale. Next, the within-plant distribution of the cotton red spider mite was studied to determine the sampling unit for this spider. Later on, by using a score sampling method, the within-plant distribution was studied to determine sample unit. A factorial 3x8 in a complete random design was used, with 10 replicates. Scores were transformed to infestation grade and used in analysis. The cotton red spider mite corresponded to Tetranychus aff. yusti McGregor. It was found that the methodology was well suited to discriminate mite in within-plant distribution and that the fourth, leaf top to down, was the ideal sampling unit.
