Population growth of Tetranychus urticae Koch (Acari: Tetranychidae) and predation rate of the pest mite by Neoseiulus idaeus Denmark & Muma (Acari: Phytoseiidae) in two grape cultivars

“…In the case of N. idaeus, other authors (WATANABE et al, 1994;COLLIER et al, 2004;DOMINGOS et al, 2014) also reported the association of this phytoseiid mite with the biological control of the two-spotted spider mite in crops like strawberry, cucumber and papaya in Brazil.…”

“…The presence of the phytoseiid mites Euseius citrifolius Denmark & Muma and Neoseiulus idaeus Denmark & Muma associated with T. urticae infestations in Brazilian vineyards (MOREIRA et al, 2010;DOMINGOS et al, 2014) have been recorded. The occurrence of N. idaeus was reported in commercial vineyards of the cultivars Sugraone and Italia Muscat, with high infestations of T. urticae in the São Francisco Valley (DOMINGOS et al, 2014).…”

“…An alternative method is the biological control with the use of predatory mites of the family Phytoseiidae, which are considered the most important agents for the biological control of phytophagous mites in agricultural systems FLECHTMANN, 2008). In Brazil, several studies on the use of phytoseiid mites for the control of T. urticae were carried out in the South and Southeast regions of Brazil, with emphasis on strawberries and ornamental plants (FERLA et al 2007;SATO et al, 2007;BERNARDI et al, 2010;IWASSAKI et al, 2015); however, studies on predaceous mites in vineyards cultivated in the Northeast region of the country are still scarce (DOMINGOS et al, 2014).…”

Predator-prey relationship in the vertical distribution of mites on grapevines

“…Neoseiulus idaeus Denmark & Muma was only found on T. urticae-infested grapevine leaves (Domingos et al, 2014). Fitzgerald et al (2008) found a higher incidence of T. urticae and N. californicus on older leaves of the plants, highlighted by a significantly positive association between both, and the incidence on different parts of the plant did not change over the sampling dates.…”

Phytoseiid mites (Acari: Mesostigmata: Phytoseiidae) from Mato Grosso State, Central-Western Brazil

“…These four species have been frequently found in Brazil, both on cultivated plants (e.g. Mineiro et al 2004, Hernandes & Feres 2006, Rezende & Lofego 2012, Silva et al 2012, Lofego et al 2013, Domingos et al 2014, Baldo et al 2018) and on plants of the Amazon Forest (Nuvoloni et al 2015b), Cerrado (Lofego et al 2004, Demite et al 2009, Rezende & Lofego 2011), and Pantanal (Mendonça et al 2019. In Mato Grosso State, E. alatus was previously reported from rubber trees (Ferla & Moraes 2002), while E. citrifolius, E. concordis and I. zuluagai were reported from rubber trees (Feres 2000, Feres et al 2002, Demite & Feres 2007, Daud & Feres 2013 and from plants of the Cerrado vegetation (Demite et al 2009).…”
