“…However, the obtained results showed that the rootstocks did not affect the population levels of the evaluated pest mites (Figure 2): P. oleivora (F 10,22 = 0.999; P = 0.473), E. banksi (F 10,22 = 0.747; P = 0.674), and T. mexicanus (F 10,22 = 0.985; P = 0.483). These results contrast with those of Silva et al (2016), who reported that natural infestations of P. oleivora and T. mexicanus on the 'Pêra' and 'Valência Tuxpan' sweet oranges were affected by the analyzed rootstocks, in some periods of the year, in the state of Sergipe. These results indicate the effect of some genotypes on the population densities of these pests.…”

-The objective of this work was to evaluate the agronomical performance of 'Piemonte' mandarin grafted on 11 rootstocks grown under the edaphoclimatic conditions of the Coastal Tablelands, in the state of Sergipe, Brazil. The following combined agronomical parameters were evaluated: vegetative growth, abundance of phytophagous mites, plant yield, drought tolerance, and physicochemical quality of fruit. 'Piemonte' mandarin had the best productive performance when grafted on 'Santa Cruz Rangpur' lime, 'Red Rough' lemon, 'Sunki Tropical' mandarin, and 'Riverside' citrandarin, and it was more tolerant to drought when grafted on 'Santa Cruz Rangpur' lime and on the LVK x LCR-010 hybrid. Rootstocks did not affect pest population levels. 'Piemonte' mandarin grafted on 'Santa Cruz Rangpur' lime and 'Red Rough' lemon produced lower-quality fruit. The 'Indio' and 'San Diego' citrandarins, the HTR-051 hybrid, and 'Swingle' citrumelo have potential for high-density plantings. 'Sunki Tropical' mandarin and 'Riverside' citrandarin are a good option for the diversification of rootstocks in orchards in the agroecosystem of the Brazilian Coastal Tablelands.

“…Some pests, among which the Texas citrus mite Eutetranychus banksi and the tetranychid Tetranychus mexicanus (Acari: Tetranychidae), as well as the rust mite Phyllocoptruta oleivora (Acari: Eriophyidae) attack citrus orchards in Northeastern Brazil (Teodoro et al, 2014;Silva et al, 2016). While E. banksi and T. mexicanus feed upon leaves of citrus trees, P. oleivora is a fruit-attacking pest that leads to reduced yield and aesthetic damage to the fruit that is similar to rust (Teodoro et al, 2014).…”

“…While E. banksi and T. mexicanus feed upon leaves of citrus trees, P. oleivora is a fruit-attacking pest that leads to reduced yield and aesthetic damage to the fruit that is similar to rust (Teodoro et al, 2014). Therefore, assessing the influence of rootstocks on the susceptibility of scions to pests is highly recommended, as cultivars show distinct genetic characteristics (Vendramim & Guzzo, 2012;Silva et al, 2016). For instance, densities of P. oleivora and T. mexicanus on 'Pera CNPMF D-6' and 'Valencia Tuxpan' sweet oranges were influenced by some rootstocks (Silva et al, 2016).…”

The objective of this work was to evaluate the effect of nine rootstocks on 'Jaffa' sweet orange (Citrus sinensis) for its vegetative, productive, and qualitative traits, and for its susceptibility to three pest mites (Eutetranychus banksi, Tetranychus mexicanus and Phyllocoptruta oleivora). The following parameters were evaluated: vegetative growth, yield, physiochemical characteristics of fruit, and density of pest mites. 'Sunki Tropical' mandarin conferred high cumulative yields whereas 'Orlando' tangelo and 'Rugoso Vermelho' lemon imparted bigger fruit with low brix, and less acidity to 'Jaffa'. Indio and 'Riverside' citrandarins induced more acid fruit of smaller sizes, as well as low-cumulated yields and canopy volumes. Also, the 'Cravo Santa Cruz' lime, 'San Diego' citrandarin, and the hybrids HTR-051 and LVK x LCR-010 conferred lower-cumulated yields to 'Jaffa'. The rootstocks did not influence the population levels of the evaluated mites. 'Sunki Tropical' mandarin, 'Cravo Santa Cruz' lime and 'Rugoso Vermelho' lemon stand up as excellent rootstock options for 'Jaffa' sweet orange in the Northeastern Brazil.

“…These chemicals affect the natural balance of the agroecosystem because of the low susceptibility of phytophagous mites to insecticides, the increased female fecundity of P. citri and P. oleivora, and mortality of biological control agents (Gerson & Weintraub, 2007;Gottwald, Abreu-Rodriguez, Yokomi, Stansly, & Riley, 2002;Silva, Vasconcelos, Gondim Junior, & Oliveira, 2006;Szczepaniec, Creary, Laskowski, Nyrop, & Raupp, 2011). Indeed, it has been reported that the overuse of acaricides for management of population outbreaks has resulted in the increased frequency of resistant individuals to the main acaricides ingredients (Doker & Kazak, 2012;Hu, Wang, Wang, You, & Chen, 2010), which increases production costs and reduces the efficiency of the system management and environmental sustainability (Silva et al, 2016).…”

Panonychus citri McGregor (“Citrus red mite”) and Phyllocoptruta oleivora Ashmead (“Citrus rust mite”) are key pests of citrus crops in the Chancay valley, Peru, causing dramatical losses in yield and fruit quality. These pest‐mites affect food security in the area, where the small farming prevails, as the citrus crop is the main generating income source for most of households. Small farmers fight against these pest‐mites by spraying nutritional elements on leaves, as it is cheaper and less harmful than using a chemical miticide. Thus, the aim of this work was determining the influence of the foliar application of elements currently used by farmers (Calcium, Magnesium, Zinc, Copper, Iron, Manganese, and Boron) and a mix of all of them at two dosage levels on the population dynamic of these two key citrus pests on tangerine cv. Clemenules, along a whole crop season in the Chancay Valley. Panonychus citri was detected on leaves during the whole crop cycle, while Phyllocoptruta oleivora was visible during the third leaf and bloom shooting period. There were not statistical differences between dosages, but statistical differences were observed between treatments and the control, the latter registering the highest population level of both mites during the whole crop cycle. Application of Cu, Mn, Mg, and Zn did show the lowest P. citri population rates, while Fe, Mix, Cu, Mg, and Zn did show the lowest population levels of P. oleivora. The foliage analysis revealed that the nutritional content of leaves of tangerine trees under study during the crop cycle was mostly at optimal levels, according to the standards for the crop. These results support the current practice of farmers and confirm that the foliar application of microelements represents a potential pesticide alternative method for management/control of citrus mites, lowering production costs, avoiding excessive pesticide applications, and increasing yield and fruit quality.
