“…Among these, two-spotted spider mite (Tetranychus urticae) is one of the main pests of strawberry crop in Brazil (Moraes & Flechtmann, 2008;Iwassaki et al, 2015), causing mesophilic cell damage and stomata closure, reduction of photosynthetic rate of the plant and reduction in final crop production. Synthetic acaricides are the most used substances to control this pest (López et al, 2014;Bernardi et al, 2015).…”

The strawberry is susceptible to several pests which cause a reduction in productivity. The use of mechanisms which repel or prevent these pests to establish, represent a sustainable environmental technology to reduce the frequency of agrochemical use. In this context, the aim of this study was to evaluate the effect of salicylic acid (SA) on resistance induction against two-spotted spider mite in strawberry cultivars (Aromas and Sweet Charlie). Five concentrations of SA (0, 25, 50, 75 and 100 mg L-1) were tested in order to verify the antixenosis effects. In SA concentration of 50 mg L-1, a reduced number of mites in the two strawberry cultivars was noticed. For the number of eggs deposited on leaflet, we verified an effect of SA concentration with quadratic adjustment in the equation. Sweet Charlie cultivar was more effective than Aromas in relation to the reduction of mite oviposition on leaflets treated with SA. SA concentrations of 25, 50 and 75 mg L-1 were the most efficient for the evaluated traits allowed to infer its potential as antixenotic resistance inducer against two-spotted spider mite in strawberry crop.

“…The main form of control of this pest is through the use of synthetic acaricides; the continual use of these products in irrigated and protected farming activities in the region has led to populations of T. urticae resistant to one of the most widely used acaricides: Ortus ® (a.i. fenpyroximate) (Iwassaki et al, 2015).…”

Effect of the essential oil from the latex of the fruit Mangifera indica L. on Tetranychus urticae Koch (Acari, Tetranychidae)

et al. 2019

Tetranychus urticae Koch is a cosmopolitan pest that causes damage to crops in protected farming activities in the semiarid region of the state of Pernambuco, Brazil. We investigated the lethal and sublethal effects of the essential oil from the latex of the mango fruit [Mangifera indica, Espada and Rosa (MESPA and MROSA) varieties] and selected monoterpenes on T. urticae. The yield of the MROSA oil was higher (9.22 ± 0.15%). The GC/MS analysis of the oils enabled the identification of 26 constituents. Terpinolene (70.14 ± 0.61%) was the major compound identified in the MESPA oil; β-pinene (38.22 ± 0.80%) was the major constituent of the MROSA oil, followed by terpinolene (29.44 ± 0.29%). The mite was more susceptible to the oils and constituents through fumigation, with no difference between the two varieties. By residual contact, the MROSA oil was 2.7-fold more toxic than the MESPA oil. Terpinolene was the most toxic constituent by fumigation, whereas β-pinene and α-pinene were the most active by residual contact. The selected compounds from M. indica also affected the behavior of the mite, exerting an influence on fecundity, feeding preference and egg-laying preference. The positive control (Azamax®) was more efficient at reducing the fecundity of the mite than the oils, but the MROSA oil was more toxic by fumigation and residual contact. The effects of fumigation and residual contact combined with the change in behavior may be a considerable advantage in the integrated management of T. urticae. For the practical use of these oils as novel acaricides, however, further investigations are needed to evaluate the effects on non-target organisms and the cost-benefit ratio for the formulation of a product to be used on protected crops in the semiarid region of the state of Pernambuco, Brazil.

“…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).…”

The two-spotted spider mite, Tetranychus urticae Koch, has caused significant damage to vineyards in the valley of the São Francisco River in Brazil. Neoseiulus idaeus Denmark & Muma is one of the most abundant species of predatory mites on vines in this region. This study evaluated the population growth rates of T. urticae on leaves of two grape (Vitis vinifera L.) cultivars ('Italia' and 'Superior Seedless') and jack bean [Canavalia ensiformis (L.) DC.] and, also, to estimate the predation rates of the pest mite by N. idaeus on leaves of both grape cultivars and jack bean. A higher oviposition rate of T. urticae was observed on 'Superior Seedless' than on 'Italia' grape leaves; however, there was no significant difference in the instantaneous growth rates of T. urticae for these grape cultivars. For 'Superior Seedless', the spider mite egg viability was significantly lower than on 'Italia' grape, indicating a resistance factor in this grape cultivar. The phytoseiid N. idaeus preyed higher number of T. urticae females on 'Superior Seedless' leaves than on 'Italia' grape and jack bean leaves for the densities of 10 and 20 pest mites per leaf arena (9 cm 2 ). Evaluations of leaf trichomes in both grape cultivars indicated the occurrence of longer trichomes on the basal portion of the main veins of 'Superior Seedless' leaves. The presence of these longer trichomes may be associated with the better performance of N. idaeus on 'Superior Seedless' leaves.
