No Brasil são gastos anualmente cerca de US$ 80 milhões para controle de Brevipalpus phoenicis, vetor do vírus leprose dos citros (CiLV). Este ácaro possui comportamento polífago e cosmopolita, presente em inúmeras espécies de plantas junto aos pomares cítricos. Neste trabalho foi investigada a poss...
The bulletin includes descriptions and figures for 165 species of plant-feeding false spider mites (Tenuipalpidae) of Mexico, of which 65 are described as new to science. Less than one-third (48) of the Mexican tenuipalpids are distributed in 8 genera (Ae...

Sixteen clones of plantain were screened for resistance to red palm mite (RPM), Raoiella indica Hirst. The plantain clones were established in 5kg pots with ten replicates. Mite infestation was carried out by introducing highly infested potted coconut palms between the plantain pots (1:10). Control ...
Major infestations of the flat mite species Raoiella indica Hirst have been reported from the Caribbean islands of Dominica, Martinique, and Saint Lucia. Specimens from these localities were examined using traditional light microscopy and low-temperature scanning electron microscopy (LTSEM) techniqu...
Citrus leprosis is a viral disease of significant economic and environmental impact in Brazil and some other countries in the Americas. Citrus leprosis virus (CiLV), its causal agent, is transmitted by Brevipalpus phoenicis (Acari: Tenuipalpidae), a polyphagous mite that reproduces through thelytoko...
The presence of the red palm mite, Raoiella indica Hirst, is reported for the first time in Brazil. This invasive mite was found in July 2009 infesting coconut palms and bananas in urban areas of Boa Vista, State of Roraima, in northern Brazil. Comments on the possible pathways of R. indica into the country, present and potential impact of its introduction and mitigating measures to prevent or to ...

The presence of the red palm mite, Raoiella indica Hirst is recorded for the first time in South America. High populations and severe damages caused by this new invasive mite were found on coconut and banana leaves in Sucre (10 degrees 27' 47' N and 64 degrees 10' 38' W) and Monagas (9 masculine46'60' N and 63 masculine12'0' W) states in northeastern Venezuela.

This is the first report of the occurrence of the Red Palm mite Raoiella indica and its damage in Puerto Rico and Culebra island. Raoiella indica is a new invasive pest threatening ornamental palm, coconut, and banana plantations. The mite was observed in eastern Puerto Rico and in Culebra island ...
Major infestations of the Red Palm Mite, Raoiella indica Hirst, have been reported in almost all the Caribbean islands and Venezuela. Correct identification of the mite and host associations is essential for the management and biocontrol of this invasive mite pest. This paper provides information o...
Although coconut (Cocos nucifera L.) is the predominant host for Raoiella indica Hirst (Acari: Tenuipalpidae), false spider mite infestations do occur on bananas and plantains (Musa spp. Colla). Since its introduction, the banana and plantain industries have been negatively impacted to different degrees by R. indica infestation throughout the Caribbean. ...
Raoiella indica Hirst (Acari: Tenuipalpidae) is a phytophagous mite that recently invaded the Western Hemisphere. This mite is a multivoltine and gregarious species that can reach very high population densities and cause significant damage to various palm species (Arecaceae). The predatory mite Amblyseius largoensis (Muma) (Acari: ...
The red palm mite, Raoiella indica (Acari: Tenuipalpidae), is an important pest of palms (Arecaceae) and other species within the Zingiberaceae, Musaceae and Strelitziaceae families. Raoiella indica was discovered in the USA (Palm Beach and Broward counties, Florida) late in 2007, and it subsequently spread to other Florida counties. The predatory mite ...
Several annual and perennial crops are severely attacked by mites from the family Eriophyidae, Tenuipalpidae and Tetranychidae. A suitable alternative commonly used in several countries for the control of these pest mites involve the use of predatory mites in the family Phytoseiidae. The phytoseiid fauna in the Brazilian natural vegetation is very rich, but nothing is known ...

The objective of this work was to study the spatial distribution of Tenuipalpus heveae Baker in rubber tree plantations. The experimental area was located in Marin�polis, State of S�o Paulo, and corresponded to a total of 1,000 plants (clone RRIM 600) divided in 100 plots of ten plants each. A total of 16 samplings were conducted, approximately once every 10 days, between December 2007 and ...
Raoiella indica has spread rapidly through the Neotropical region where the mite damages economically and ecologically important plants. Three studies were conducted to determine the host plant range of R. indica, using the presence of colonies containing all life stages as an indicator of reproductive suitability.
