Primeiro registro de parasitoides de ovos de Oebalus poecilus (Dallas, 1851) (Hemiptera: Pentatomidae) em arroz no Maranhão, Brasil

Abstract

First record of egg parasitoids of Oebalus poecilus (Dallas, 1851) (Hemiptera: Pentatomidae) in rice in Maranhão, Brazil
 This is the first report of the species Trissolcus urichi (Crawford, 1913) and Telenomus podisi Ashmead, 1893 (Hymenoptera: Platygastridae) parasitizing Oebalus poecilus (Dallas, 1851) (Hemiptera: Pentatomidae) eggs in rice in Maranhão, Brazil. These parasitoids were collected in the municipality of Itapecuru Mirim, MA, in an area of 0.2 ha cultivated with rice. The eggs collected exhibited an average parasitism of 11.4%. Twenty egg parasitoids were collected and identified, these being one Tr. urichi and nineteen Te. podisi. The presence of these naturally occurring parasitoids in the field opens perspectives for updating the species of parasitoids that parasitize pentatomid eggs in rice fields in Brazil.

Biology of Glyphepomis dubia Campos & Souza, 2016 (Hemiptera: Pentatomidae) and the parasitoids Telenomus podisi Ashmead, 1893 and Trissolcus basalis (Wollaston, 1858) (Hymenoptera: Platygastridae) on rice

“…In Brazil, the specie Te. podisi was reported including T. limbativentris (Idalgo et al, 2013;Maciel et al, 2007;Riffel et al, 2010), O. poecilus (Dallas) (Melo Neto et al, 2020) and G. adroguensis (Farias et al, 2012). In Panama, in addition to Te.…”

New Records of Egg Parasitoids of Stink Bugs (Hemiptera: Pentatomidae) on Rice in Piauí, Brazil: Rate Parasitism, Incidence and Seasonality

“…Telenomus podisi is the parasitoid mostly associated with Hemiptera (Zerbino & Panizzi 2019). In rice, this parasitoid has been registered in T. limbativentris eggs (Maciel et al 2007;Riffel et al 2010;Idalgo et al 2013), Glyphepomis adroguensis Berg, 1891 (Farias et al 2012), and O. poecilus (Margaría et al 2009;Melo Neto et al 2020). As for O. anasae, its occurrence is reported in other crops of agricultural importance (Paz-Neto et al 2015) where it is an important biological control agent for stink bugs.…”
