ABSTRACT
The red spider mite Tetranychus neocaledonicus André (Acari: Tetranychidae) is commonly found on cotton and castor bean in Brazil, especially in the northeast, but to date it had not been found damaging cultivated peanut. The objective of this research was to record the occurrence of this mite on peanut plants and describe its damage on this Fabaceae. The peanut plants, when infested by this mite, exhibit initially small whitish spots on the leaves, which quickly develop to chlorotic spots, followed by silvering, drying and fall because of their feeding. The severity of the damage caused to peanut and the adaptability of the mite to warm and dry conditions indicate that this species has potential as peanut pest in northeastern Brazil.
Key words
Tetranychidae; Arachis hypogaea; pest; neotropical region
Several arthropod pests may cause severe losses in the agro-ecosystem of the peanut, Arachis hypogaea L. (Fabaceae), reducing the productivity of this crop (Biswas and Das 2011Biswas, G.

). The spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) is considered the most harmful species to this crop in several countries (Johnson et al. 1982Johnson, D. R., Wynne, J.

In Brazil, four mite species are cited as peanut pests: the spider mite T. urticae, the green mite Mononychelus planki (McGregor), the red mites Tetranychus evansi Baker and Pritchard and Tetranychus ogmophallos (Ferreira and Flechtmann), but only M. planki and T. ogmophallos are reported as potential pests of this crop (Bonato et al. 2000Bonato, O., Santarosa, P.

On June 30th 2015, it was performed a planting of the peanut with drip irrigation, variety BRS L7, spaced 0.70 × 0.20 m in an area of 479.8 m2 in the Embrapa Cotton Experimental Station of Campina Grande, State of Paraíba, located lat 7°13’28”S and long 35°54’20”W.
Forty days after emergence, 12% of peanut plants were infested by mites and, after only three weeks, this percentage increased to 28%. At 90 days after planting, 64% of the plants were infested.
At the beginning, the plants attacked by the mite had small whitish spots on the leaves, which evolved quickly to chlorotic spots, followed by silvering, drying and fall. The new leaves of peanut, located at the apical portion of the plant, rolled up (Figure 1a), and the oldest, located at the median and basal portion of the plant, became silvery (Figure 1b) and then were covered by the web (Figure 1c). Mites were found on both sides of the leaves (Figure 1d).
Characteristics of the damage caused by red spider mite, Tetranychus neocaledonicus (Acari: Tetranychidae), in peanut. Leaves of peanut rolled (a), silvery (b), covered with web (c) and with mite colony (d).
The mites were identified under microscope with phase contrast (Brand Olympus Model BX41) as Tetranychus neocaledonicus André, 1933 (Acari: Tetranychidae) by Dr. Manoel Guedes Correa Gondim Junior from the Departamento de Agronomia/Fitossanidade of the Universidade Federal Rural de Pernambuco.
Tetranychus neocaledonicus was first described from cotton in New Caledonia, Oceania. It is currently reported from about 430 hosts (Ehara and Yamaguchi 2001Ehara, S. and Yamaguchi, T. (2001). Discovery of Tetranychus neocaledonicus Andre (Acari, Tetranychidae) from Amami-Oshima Island, Japan. Plant Protection, 55, 268-272.; Gupta 2005Gupta, S. K. (2005).

Identification of exotic pest and Australian native and naturalised species of Tetranychus (Acari: Tetranychidae). Zootaxa, 2961, 1-72.). Species widely distributed in tropical and subtropical areas of the world, T. neocaledonicus is also considered an important pest in India (Goff 1986Goff, M. L. (1986). Spider mites (Acari: Tetranychidae) in the Hawaiian Islands. International Journal of Acarology, 12, 43-49. http://dx.doi.org/10.1080/01647958608683437.

). In Brazil, this species is a common occurrence in cotton and castor bean, especially in the northeastern region (Poderoso et al. 2010Poderoso, J. C. M., Ribeiro, G. T., Návia, D., Passos, E. M., Gonçalves, G. B., Correia-Oliveira, M. E. and Dantas, P. C. (2010). Primeiro registro no Brasil de Erythrina velutina Willd. como hospedeira de Tetranychus neocaledonicus (Acari: Tetranychidae).

http://dx.doi.org/10.1590/S1516-05722010...
), but to date it had not been found damaging cultivated peanut.
Eggs of this mite are spherical and translucent when recently deposited, but gradually become brown. The larva is bright amber in the hatching, but it assumes a green color with dark lateral spots. The protonymph and deutonymph are green with dark spots on the dorsum, but the adults are carmine red (Figure 1d). Female duplex setae divide tarsus I into three subequal parts; proximal tactile setae posterior to proximal duplex; empodia without dorsal spur (Moraes and Flechtmann 1981Moraes, G. J. and Flechtmann, C. H. W. (1981). Ácaros fitófagos do nordeste do Brasil. Pesquisa Agropecuária Brasileira, 16, 117-186.). The empodia of tarsus I of the male is claw-like; others empodia are divided into three pairs of distally by directed ventrally hairs (Jeppson et al. 1975Jeppson, L. R., Keifer, H. H. and Baker, E. W. (1975). Mites injurious to economic plants. Berkeley: University of California Press.).
The infestation was observed between August and September 2015, when the average temperature, relative humidity and precipitation were 24 °C, 70% and 0.4 mm, respectively, in the Campina Grande region.
The severity of the damage caused by T. neocaledonicus to peanut plants and its adaptability to warm and dry weather conditions indicate that this mite has the potential to become a pest of economic importance for this crop in the northeastern Brazil.
