Stink bugs (Hemiptera: Pentatomidae) are economic pests of a variety fruit crops across the southeastern USA, and damage by stink to peaches is common. The landscape surrounding orchards may influence bug distribution dispersal into this commodity, but such patterns vary over growing season. Accordingly, control should be targeted seasonally towards habitats that effectively reduce or prevent p...

The aggregation and mating behavior of the stink bug, Euschistus conspersus Uhler (Hemiptera: Pentatomidae) was investigated in a series of field and laboratory experiments. Marking of E. conspersus mating in aggregations in the field demonstrated that both sexes mate multiple times within aggregations on successive nights and with different partners, although ≈ 20% of the individuals of both s...

The aim of this work was to study the feeding habits of the predator Brontocoris tabidus (Heteroptera: Pentatomidae) analyzing the salivary gland complex (SGC). The SGC was dissected and subjected to histological analyses and biochemical assays. Results showed that a pair of bilobed principal salivary glands and one pair of tubular accessory salivary glands form the SGC and different parts of s...

The spermathecal morphology of nine species belonging to the Pentatomidae (Insecta: Heteroptera) were compared by optical and scanning electron microscopy (SEM). Among the examined species [Rhaphigaster nebulosa (Poda 1761), Palomena prasina (Linnaeus 1761), Piezodorus lituratus (Fabricius 1794), Graphosoma lineatum (Linnaeus 1758), Graphosoma semipunctatum (Fabricius 1775), Aelia albovittata (...

The COI gene as the core of the DNA barcoding system for animals has received significant attention. The observed wide overlap between intraand interspecific sequence variability has led researchers to envisage the primary COI-based method. The sequences of 16S rDNA, COI, and Cyt b genes of Nezara virudula (L.) (Hemiptera: Pentatomidae) from 13 countries and the same sequences of N. antennata S...

Os conteúdos das glândulas metatorácicas de insetos adultos do percevejo Dichelops melacanthus (Hemiptera: Pentatomidae) foram analisados. Os compostos de defesa foram identificados combinando as técnicas de cromatografia gasosa (CG), cromatografia gasosa acoplada à espectrometria de massas (CG-EM) e por comparação de seus índices de retenção com os de compostos padrões. Tridecano foi o compone...

A catalog of type specimens of Heteroptera (Insecta: Hemiptera) deposited in the Instituto Nacional de Pesquisas da Amazônia (INPA), Manaus, Brazil, is presented and updated to May, 2012. A total of 37 holotypes and 61 lots of paratypes of 78 species are listed in their families: Miridae and Reduviidae (infraorder: Cimicomorpha); Mesoveliidae and Velfidae (Gerromorpha); Belostomatidae, Naucorid...

Reproduction and longevity of Supputius cincticeps (Stål) (Heteroptera: Pentatomidae) fed on Zophobas confusa Gebien, Tenebrio molitor L. (Coleoptera: Tenebrionidae) or Musca domestica (L.) (Diptera: Muscidae) larvae were studied during two generations at 24.7 ± 1.1oC, 70 ± 10% R.H. and 12 h of photophase. Body weight of newlyemerged adults, oviposition period, number of egg masses, total numbe...
