Collection and detection of eriophyoid mites

Abstract

Methods for collecting and detecting eriophyoid mites are crucial components in research, taxonomical and biological studies, and control programs for these organisms. Their small size, their specific host-plant interactions and their hidden life-style make them difficult to find in routine inspections. This review examines successful and unsuccessful approaches for collecting eriophyoid mites, and makes recommendations for their detection, supporting studies in taxonomy, ecology, biology, molecular systematics and population genetics.

“…Devido ao reduzido tamanho, o método empregado para a coleta e a detecção de C. vitis apresenta papel decisivo tanto na pesquisa quanto em programas de controle (MONFREDA et al, 2010), sendo utilizados com frequência armadilhas adesivas (BERNARD et al, 2005;WALTON et al, 2007) (STRECK et al, 2008), no sistema de espaldeira, com espaçamento de 3,0m entre as fileiras e 1,0m entre as plantas, com histórico de infestação por C. vitis.…”

Field assessment of host plant specificity and potential effectiveness of a prospective biological control agent, Aceria salsolae, of Russian thistle, Salsola tragus

“…Mites that were motile were recorded as being alive. Cuttings were first examined for presence of live mites at 30Â magnification, then all mites were extracted from the cutting using a soapy solution and counted (Monfreda et al, 2007). On 13 September a sample of five 10-cm branch cuttings was collected from each plant and held in a refrigerator until mites were extracted and counted.…”

What’s “cool” on eriophyoid mites?

“…An aggregated and uneven distribution of eriophyoids has been widely studied within plants and their organs (intraplant distribution) often indicating some site preferences (e.g. Davies et al 2001a;Fernando et al 2003;Kawai and Haque 2004;de Lillo et al 2005a;Kuczyński and Skoracka 2005;Walton et al 2007;Bertoldo et al 2008;Monfreda et al 2009). In most cases, especially when the host is a tree or a bush, the whole plant cannot be sampled.…”

“…Extensive efforts have been made during the last decade and many investigations have contributed to developing simpler and easier ways of detecting and collecting mites other than direct counts of mites on samples of plants. Each of these procedures is intended to increase efficiency and confidence in estimating and assessing populations, in counting specimens, and in saving time (reviewed by Monfreda et al 2009). Of particular relevance is the application of a surfactant (e.g.…”
