Flowers and fruits from six plants per hectare were sampled by the hitting technique. Frankliniella occidentalis (Pergande), F. schultzei (Trybom), F. gardenia (Moulton), F. condei John, F. insularis (Franklin) and Thrips tabaci Lindeman, in Thripidae, and Haplothrips gowdeyi (Franklin), in Phlaeothripidae were identifi ed. F. occidentalis was dominant, comprising 55.7% of the total specimens sampled. Slight and severe injuries were registered in fruits.KEY WORDS: Rosaceae, thysanopteran, pest species, habitPeach, Prunnus persica L. Batsch, is the eighth most produced fruit in the world, with about 15.4 millions of tons/year (FAO 2005). Peach represents one of the main temperate fruit tree cultivated in Brazil, where 213,545 tons were produced in the 2003-2004 season (Almeida & Duringan 2006). In São Paulo State this culture has a signifi cant economic importance, mainly in the region of Avaré, Estância Turística de Paranapanema, with 43,636 tons (IBGE 2005).Worldwide, some thrips species are pests of economic importance in stone fruits. In Brazil, Haplothrips gowdeyi (Franklin) and Frankliniella condei John were registered in nectarine, in Santa Catarina State (Hickel et al. 1997, 1998). Monteiro et al. (1999) reported Frankliniella occidentalis (Pergande) in leaves and fruits of peach trees in São Paulo State. This is the most important vector species of tomato spotted wilt virus (TSWV) (Moritz et al. 2004). Thrips are minute insects measuring from 0.5 to 15 mm in length (Mound & Marullo 1996), bearing fringed wings and remarkable piercing and sucking mouth parts (Mound 2005). Most of them are phytophagous, but they might also act as predators, pollinators, fungivorous and even as ectoparasitoids (Mound & Marullo 1996, Mound 2000, Izzo et al. 2002, Pinent et al. 2002). The identifi cation of thrips species helps injury recognition, and thus the adoption of control measures.In New Zealand, Thrips obscuratus (Crawford) is a key pest in orchards of stone fruits, and constitutes an endemic species of that country (Mound & Walker 1982). The feeding activity of phytophagous thrips may cause discoloring followed by silvering of plant tissues which is solely cosmetic damage. Nevertheless T. obscuratus is implicated in the mechanical transport of Monilinia fructicola (Winter) that causes the brown rot (Teulon & Penman 1996). In Chile, Ripa et al. (2001) registered the presence of F. occidentalis causing injuries in terminal buds of nectarine.The present study aimed to identify thrips species associated to peach in Paranapanema, SP. and characterize the kind of damage they cause.Between May and August of 2005, thrips were collected weekly in ten fl owers and ten fruits from six plants per hectare at each five of the plots by hitting flowers and July - August 2008 Neotropical Entomology 37(4) 487fruits on a tray. Dislodged thrips were collected with a fi ne paintbrush, mounted in microscope slides as proposed by Mound & Kibby (1998) and identifi ed. Peach cultivars sampled were ‘Aurora’ and ‘Tropic Beauty’ and the orchards were located at Holambra II district, Paranapanema, SP (23º45´71´´S 48°89´28´´W). Injuries were visually evaluated and categorized from slight to severe according to their intensity (Fig. 1). The reference slides are available at the BIOECOLAB/UFRGS collection. Seven thrips species were identified: Frankliniella schultzei (Trybom), F. occidentalis,  F. gardenia (Moulton), F. condei, F. insularis (Franklin), Thrips tabaci Lindeman, belonging to Thripidae, and H. gowdeyi, to Phlaeothripidae. Thripidae encompasses the majority of species considered as pests; meanwhile, approximately 50% of the Phlaeothripidae feed exclusively on fungi. From a total of 115 individuals, F. occidentalis was the most abundant (55.7%). This species is native from California and Mexico, but currently it has been found widely distributed in the Neotropical region. In Brazil, it has been registered since 1993 and nowadays may be found in fl owers of ornamental plants and in fruits and leaves of peach trees causing damage (Monteiro et al. 1999). Recently the species was registered by Pinent et al. (2007) in grapevine, persimmon tree, and strawberry plants in Rio Grande do Sul. In peach trees F. occidentalis caused fruit deformation, besides scaring fruit surface (Fig. 1A-B). F. schultzei (25.2%) is a South American native thrips that is widely disperse in tropical countries, including those in Africa and Australia. It feeds on fl owers and leaves of many plants, and is implicated in TSWV spread also causing brown spots and fruit deformations (Fig. 1A-C). In some regions of Australia, it is considered an important predator of mite eggs in cotton culture (Wilson et al. 1996). In Brazil it is known as a predator of Polyphagotarsonemus latus (Banks) e Tetranychus urticae Koch mites (Monteiro et al. 1999). F. insularis (7.0%) is a Barbados native species and widely distributed in tropical countries, including Brazil. It feeds on Leguminosae plants (Mound & Marullo 1996). In Rio Grande do Sul, it was registered in fl owers of spontaneously growth plants of Asteraceae, Lamiaceae, Fabaceae and Verbenaceae (Pinent et al. 2003, 2005). T. tabaci (7.0%) may be found in leaves of asparagus, and of chive and garlic, and in fl owers and leaves of soybean, generally causing considerable economic damages. Just four species from this Holartic genus occur in Brazil (Monteiro et al. 2001). Mound (2005) pointed out that this species is  losing its pest status, either by the diminishing of its populations or by the weakening of its role as tospovirus vector. F. gardenia (2.6%) was described from Mexico and it is known as the species with the most yellow body dwelling in fl owers (Mound & Marullo 1996). In the southeast region of São Paulo State, it was found in citrus, damaging fl ower buds (Monteiro et al. 1999). H. gowdeyi (1.7%) has probably an African origin, being widely distributed on the tropics. It is recognized as a fl ower thrips in Caribbean regions. Accordingly to Hickel (2004) it was collected feeding on the ovary of nectarine fl owers. Pinent et al. (2007) registered it in strawberry plants in Rio Grande do Sul.  F. condei (0.9%) was described from specimens collected in Ribeirão Preto, SP, in a Bromeliaceae species (Monteiro et al. 2001). Hickel & Ducroquet (1998), Fig. 1. Peach fruits, P. persica, injured by thrips. A. Deformations and browning considered as severe injury; B. Peach fruit with severe injury caused by thrips feeding; C. Severe scarring in peach fruit caused by thrips feeding; D. Peach fruit with sligth injury caused by thrips feeding; E. Thrips larva on young peach fruit.A BC D E488     Pinent et al. - Thrips (Thysanoptera: Thripidae, Phlaeothripidae) Damaging Peach in Paranapanema...in Santa Catarina State, found this thrips causing fl owers and young fruit dropping as well as deformations in the surface of nectarine fruits. The highest infestations were registered for F. occidentalis and F. schultzei, with more severe damage in fruits, suggesting that threshold levels should be determined. To F. insularis, T. tabaci, F. gardenia, H. gowdeyi and F. condei slightly injuries were attributed (Fig. 1D). The larvae identifi cation was not possible because different thrips species were found frequently on same fl owers indicating that these peach is a host (Fig.1E).AcknowledgmentsTo the peach growers Johanes H.
