Ácaros predadores associados ao ácaro-da-erinose da lichia

Abstract

Predator mites associated with the litchi erinose miteAbstract -The objective of this work was to identify predator mites present in lychee plants and to correlate these species population development with the one of the litchi erineum mite, Aceria litchii. The research was carried out in the county of Casa Branca, SP, Brazil, with mature trees of the Bengal variety, with 12 years old. From August 2008 to September 2009, leaves were collected monthly for the evaluation of A. litchii and predatory mites population levels. Registers were made for 6,557 mites of the Phytoseiidae family. The most abundant species was Amblyseius compositus (42.6%), followed by Phytoseius intermedius (31.2%), Euseius concordis (14.1%), Amblyseius herbicolus (8.8%) and Iphiseiodes zuluagai (3.3%). Population development of A. compositus, E. concordis and I. zuluagai was positively correlated with the one of Aceria litchii, indicating a predation relationship.

Range Expansion of the Litchi Erinose MiteAceria litchii(Acari: Eriophyidae) in Brazil

“…Litchi plants with severe erinose symptoms in young and developing leaves were detected in Brazil in Jan 2008 in an orchard of 3,000 thirteen-yr-old litchi plants of the cultivar 'Bengal' in the municipality of Limeira, São Paulo State. A dense population of this mite was detected during the litchi fruiting period, and this represents the first report of A. litchii in South America (Picoli et al 2010;Raga et al 2010).…”

“…(Acari: Phytoseiidae), and Agistemus spp. (Acari: Stigmaeidae) are associated with LEM worldwide, including Brazil (Picoli et al 2010). The number of species and endemism of predatory Phytoseiidae mites are high in the Neotropical region (Tixier et al 2008).…”

Detection of the Lychee Erinose Mite, Aceria litchii (Keifer) (Acari: Eriophyidae) in Florida, USA: A Comparison with Other Alien Populations

“…Several active ingredients have shown some efficacy on LEM [15,41]. The main management strategy focuses on protection of new flush after the postharvest sanitation through carefully timed acaricide applications [39,42]. Sprays of dimethoate or wettable sulfur at 2-3 week intervals, starting at bud emergence until leaves have hardened, provided protection of new flush against LEM in Australia [39].…”

“…Biological control might provide a long-term solution to managing this invasive mite. Several natural enemies have been reported in association with LEM in India [45], Australia [46,47], Brazil [42,48] and China [49]. However, predation on LEM has only been confirmed for a few species of phytoseiid mites, including Amblyseius largoensis (Muma) in China [50], and Phytoseius intermedius Evans and MacFarlane in Brazil [48].…”

The Lychee Erinose Mite Aceria litchii (Keifer) (Acari: Eriophyidae)

“…Chemical control in combination with pruning is the main approach that is followed worldwide for managing LEM infestations. Several active ingredients have shown some efficacy (Schulte et al 2007;Azevedo et al 2013), but satisfactory control can only be achieved through carefully timed treatments to protect the new flush (Waite 2005;Picoli et al 2010). In other regions with LEM, foliar applications are made of various miticides (Castro et al 2018;Nadhida and Holdway 1955;Schulte et al 2007;Waite 2005).…”
