“…Pelo fato de que outras espécies de percevejos estão se adaptando à cultura do girassol no Norte do Paraná (Malaguido & Panizzi 1998) e pelo fato de haver duas épocas de cultivo, aumentando a exposição das plantas aos insetos, não só o percevejo E. heros, mas outras espécies poderão se tornar pragas importantes da cultura, podendo exigir medidas de controle para evitar danos econômicos.…”

An. Soc. Entomol. Brasil 27(4): 535-541 (1998) Damage of Euschistus heros (F.) (Hemiptera: Pentatomidae) to Sunflower Seeds ABSTRACT -Quantitative and qualitative damage of Euschistus heros (F.) to sunflower (Helianthus annuus L.) seeds were evaluated in the field, at Embrapa Soja, in Londrina, PR. Cages (2.0 x 2.0 x 1.5m) were installed and covered with a nylon net containing 10 plants/cage of cv. Embrapa 122-V2000. The plants were infested with 2, 4 or 8 adults of E. heros/plant, in the following periods: R3 stage (second stage of blooming with bud lenghtening) to harvest; R6 stage (final blooming) to harvest; and R9 stage (seeds physiologically mature) to harvest. Test cages were kept without insects. Yield (kg), weight of 1000 seeds (g), and seed germination (%) were reduced significantly with infestations of 8 bugs/ plant during R3 to harvest. Percentage of protein on seeds was higher, in relation to other seed components, with this same level of bug infestation and at the same plant phenological stage. However, these differences were not observed with 2 or 4 bugs/plant either at R6-harvest or R9-harvest infestation periods.KEY WORDS: Insecta, Heteroptera, stink bug, Helianthus annuus. RESUMO -Avaliou-se os danos quantitativos e qualitativos do percevejoEuschistus heros (F.) aos aquênios de girassol (Helianthus annuus L.). O experimento foi conduzido na área experimental da Embrapa Soja, em Londrina, PR, onde foi semeada a cv. Embrapa 122 -V2000. Foram instaladas gaiolas (2,0 x 2,0 x 1,5m) cobertas com tela de nylon, contendo duas fileiras de girassol, totalizando 10 plantas/gaiola. As plantas foram infestadas com adultos de E. heros, nos níveis de 2, 4 e 8 insetos/planta, nos seguintes períodos: estágio R3 (segunda fase de alongamento do broto floral) até a colheita; estágio R6 (fase final de florescimento) até a colheita; e estágio R9 (maturação fisiológica dos aquênios) até a colheita. As gaiolas testemunhas permaneceram livres de insetos. O rendimento (kg), o peso de 1000 aquênios (g) e o poder germinativo dos aquênios (%) foram reduzidos significativamente durante o período R3 até a colheita com a infestação de 8 insetos/planta. A percentagem de proteína dos aquênios foi superior, relativamente aos outros componentes, com o mesmo nível de infestação e durante o mesmo período. Entretanto, estas diferenças não

On September 2009, the species was recorded for the Origin of samples of Cannabis sativa through insect fragments associated with compacted hemp drug The red-shouldered stink bug T. perditor is a pest well known in cultures of wheat, rice, sorghum (Panizzi 1997), and sunflower (Malaguido & Panizzi 1998) in Brazil, and has been also recorded, although less frequently, as a soybean pest (Panizzi 1997).

“…Yet, it is one of the main pests of soybean crops in Colombia (Corrêa-Ferreira & Panizzi 1999). T. perditor has a wide distribution across the Neotropical Region (Hoffman-Campo 2000), being recorded in some states of the southeast and midwest Brazil (Busoli et al 1994;Panizzi 1997;Malaguido & Panizzi 1998) as well as additional states in southern, northern and northeastern Brasil (pers. comm., Dr. Jocélia Grazia).…”

ABSTRACT. Origin of samples of Cannabis sativa through insect fragments associated with compacted hemp drug in South America. Insects associated with a seizure of Cannabis sativa L. may indicate the origin of the illicit drug. Nevertheless, no work regarding this subject has been previously published for South America. In the present investigation, seven kilograms of vegetal material (C. sativa) were inspected for insect fragments. Three species were identified and used to test the origin of the seizure of cannabis plant material: Euschistus heros (Fabricius, 1794), Thyanta perditor (Fabricius, 1794) (Heteroptera, Pentatomidae), and Cephalotes pusillus (Klug, 1824) (Hymenoptera, Formicidae). These insect species restricted the geographic origin of the drug to the Neotropical region, and their distribution patterns showed an overlap of the State of Mato Grosso (Brazil), Argentina, and Paraguay. Based on this information, two of the three major C. sativa growing areas in South America were excluded: (1) the Colombian territory and (2) northeastern Brazil.

“…Rizzo ( 1971 ) presented detailed information on the biology, immature stages, fi eld ecology, and host plants of Edessa meditabunda . This species has been the subject of studies regarding its association with and damaging potential to soy-bean (Silva et al 2012 ) and sunfl ower (Malaguido and Panizzi 1998b ) and nymph development and feeding behavior (Panizzi and Machado-Neto 1992 ); also, the behavior of newly hatched nymphs on the corions has been recently studied in detail (Calizotti and Panizzi 2014 ). Rizzo and Saini ( 1987 ) presented biology data on Edessa rufomarginata .…”

The Pentatomidae, representing the fourth largest family within Heteroptera, are one of the most diverse groups with about 800 genera and more than 4,700 species in the world. In the Neotropics, about 230 genera and 1,400 species are included in seven subfamilies of the world's nine subfamilies; four subfamilies are exclusively of the Neotropics. In this chapter, for each subfamily, a diagnosis, an overview of the classifi cation, and information on life history, ecology, and economic importance are given. Comprehensive keys and diagnosis to the subfamilies, tribes, and genera for the Neotropical Region, including Mexico, Central and South America, and the West Indies, are also given.
