Dinâmica populacional de ácaros fitófagos (Acari, Eriophyidae, Tenuipalpidae) em seis clones de seringueira no sul do Estado de Mato Grosso

Biological cycle of Tenuipalpus heveae Baker (Acari, Tenuipalpidae) on leaflets of three rubber tree clones

“…This technique could be easily applied in rubber tree crops, because hundreds of varieties (clones) are now available as result of studies developed along decades (Alvarenga & Carmo 2008). Evidences that rubber tree clones present differential response to T. heveae attack have been already suggested by Daud & Feres (2007), who observed higher abundance of these mites on the clones RRIM 600, PR 255 and PB 235, and lower numbers on PB 260, in southern Mato Grosso crops. No studies have been conducted to this date to detect differences in the susceptibility of rubber tree clones to T. heveae attack.…”

“…Daud & Feres (2007) verified that the clones PB 235, PR 255 and RRIM 600 were the most vulnerable to the attack of this phytophagous mite in crops in the southern State of Mato Grosso. Monteverde (2006) observed higher level of infestation in seedlings of PB 235 than in RRIM 600, in a study conducted in greenhouse.…”

“…Ferla & Moraes 2002;Demite & Feres 2005;Hernandes & Feres 2006a,b;Vis et al 2006 andFeres 2007). Not withstanding, relatively few studies were conducted concerning the biological aspects of the main phytophagous mites associated with this plant Ferla & Moraes 2003a;Hernandes et al 2006).…”

“…The male and the immature stages were described more recently by Pontier & Flechtmann (1999) and Pontier & Flechtmann (2000), respectively. Only after 2000 T. heveae was reported as a potential pest of rubber trees Ferla & Moraes 2002;Hernandes & Feres 2006a, b;Vis et al 2006;Daud & Feres 2007). These mites are slow-moving and occur mainly on the lower surface of the leaflets, despite some individuals may be found on the upper surface when large infestations occur (Feres 2000).…”

Mites (Arachnida: Acari) collected on rubber trees Hevea brasiliensis (Willd. ex A.Juss.) Müll.Arg. in Santana, Amapá state, Brazil

“…It is also found in the states of Amazonas, Goiás, Mato Grosso, and São Paulo (Moraes and Flechtmann, 2008). After the year 2000, T. heveae was reported a number of times as a pest of rubber trees (Pontier et al, 2000;Ferla and Moraes, 2002;Hernandes and Feres 2006a, b;Vis et al, 2006;Daud and Feres, 2007). In São Paulo, T. heveae is usually very numerous (Feres et al, 2002;Bellini et al, 2005;Hernandes and Feres, 2006a;Vis et al, 2006).…”
