Nova planta hospedeira e novos padrões cromáticos de Pachycoris torridus (Scopoli) (Hemiptera: Scutelleridae) no Brasil

Abstract

-The occurrence of Pachycoris torridus (Scopoli) on Schinus terebinthifolius Raddi (Anacardiaceae), is recorded for the first time. The specimens were collected in Piracicaba, State of Sao Paulo; only four out of 43 adults showed new spots morphs of pronotum and scutellum.

Occurrence of Pachycoris torridus (Scopoli,1772) (Hemiptera:Scutelleridae) on Physic Nut(Jatrophacurcas) in Northwest of Sao Paulo,Brazil

“…In Brazil, the occurrence of P. torridus was reported in at least 15 states (Table 1). In Sao Paulo, the species was observed only in the cities of Jaboticabal, Araras, Campinas, Itapira, Piracicaba and Tatui [7,[9][10][11][12]. In this context, this work notifies, for the first time, the presence of P. torridus in northwestern of Sao Paulo, Brazil.…”

“…torridus belongs to the Hemiptera order and Heteroptera suborder, insects popularly called stink bug. This Heteroptera presents longevity, live for up to 600 days [7], are phytophagous and polyphagous, with a record of their attacks in 16 vegetable crops [8], with wide distribution in the Neotropical region [9]. In Brazil, the occurrence of P. torridus was reported in at least 15 states (Table 1).…”

Ecology and behavior of Pachycoris torridus (Hemiptera: Scutelleridae): new host plant, color polymorphism, maternal care and parasitism

“…Whenever a female was found guarding eggs or nymphs, the whole leaf used was collected to evaluate the offspring number of each adult morph. The morph patterns of P. torridus were described according to Monte (1937) and Sánchez-Soto et al (2004). Voucher species were deposited in the Museum of Zoology, University of Rio Janeiro (MZURJ).…”

“…Though Pachycoris species often feed on Euphorbiaceae, P. torridus has been recorded on 12 phylogenetically unrelated host plant species of economic importance in Brazil [for a complete list see Sánchez-Soto & Nakano, (2002) and Sánchez-Soto et al, (2004)]. In Paraguay, Hussey (1934) described the occurrence of this species on Sapium haematospermum Múll.…”

“…Otherwise, few studies were accomplished for P. torridus. Hussey (1934) described the guarding behavior of this species in Paraguay while Monte (1937) described various color patterns, and recently two other studies have been conducted in agrosystems in Brazil (see Sánchez-Soto & Nakano, 2002;Sánchez-Soto et al, 2004).…”
