69. Gallobelicus tenuis (Reuter) (fig. 18, a, b).Cyrtopeltis tenuis Reuter, Rev. d'Ent. 14: 139, 1895.One specimen, Piti, May 1; 10 specimens, Piti, May 10, all on tomato, Usinger; one specimen, Agana Swamp, May 4, Usinger; two specimens, Talofofo, Nov. 18, Swezey; one specimen, Guam, Fullaway (1196); TODO 16 specimens, Machanao, June 30, on Nicotiana, Usinger; one specimen, Fonte Valley, Aug. 7, on weeds, Swezey. Swezey and Zimmerman took specimens of tenuis in Samoa.Few species of insects are in a more confused state both taxonomically and nomenclatorially than the dicyphine pests of tobacco and tomato. Their small size and superficial similarity have contributed to this but do not excuse the situation, for the male terminalia exhibit striking differences which are specifically distinct and point the way to a sound generic classification. The literature on the subject was summarized by China (Ann. Mag. Nat. Hist. XI, 1: 604- 607, 1938) although Kirkaldy's description of Cyrtopeltis (?) nicotianae (Linn. Soc. N. S. Wales, Proc. 33: 377, 1908), Froggatt's description of Dicyphus tabaci (Agric. Gaz. N. S. Wales 31: 715, 1920), and Knight's discussion of the genus Cyrtopeltis (Brooklyn Ent. Soc., Bull. 17:65-67, 1922) were omitted.China concluded that nicotianae Koningsberger, crassicornis Distant, javanus Poppius, and nocivus Fulmek were all synonyms of tenuis Reuter, stating that Fulmek's figures of the left genital claspers of different species (Deli Proefstation, Bull. 25: 4, 1925) were not of the same organ but of different parts of the same insect. To quote China further, "Judging by the shape of the Haftzange in nicotianae it appears to be a broken portion of the inferior lateral margin of the pygophor (ninth abdominal segment) viewed from the left side of the pygophor but with the drawing actually reversed."In the case of nocivus he figured the actual paramere, calling it again the "Zinke Haftzange." Careful comparison of Fulmek's figures with the two species which I found on tobacco on Guam reveals that Fulmek was correct, his drawings actually being of homologous structures of two distinct species. The left clasper of nicotianae is truly an amazing structure and corresponds, except for minor details in structure of the apex of the broad lobe, with my Guam specimens. The last abdominal segment also differs strikingly in the two species, nicotianae having a bifurcate posterior process suggestive of the American tobacco bug, Engytatus geniculatus Reuter (fig. 19, a, b), whereas tenuis (= nocivus Fulmek) has a simple main posterior process (see China's excellent figure of a cotype).The generic classification of the Dicyphinae has long been confused so that Reuter, Poppius, and Horvath as well as other, lesser, authorities changed species from one genus to another with no apparent reason, only to change them back again. Knight has lumped many of these into the genus Cyrtopeltis, a practice which is at least consistent though making it almost impossible to use his keys to the genera. In this work I have concluded that the male terminalia provide us with the only sound basis for a generic classification of the Dicyphinae. Reluctance to base a higher classification upon characters of one sex is understandable but this practice has been found necessary in other groups (scale insects and Lepidoptera) and seems justifiable in the Dicyphinae considering the hopeless confusion that has resulted from attempts to classify these bugs on the basis of such superficialities as size of eyes or color of head and pronotum.The following characters will suffice to distinguish the questionable Dicyphine genera in so far as my material is concerned. Modifications will undoubtedly be necessary when further material is examined. I have not seen the types of Dicyphus and Macrolophus.Dicyphus Fieber (type pallidus Herrich Schaeffer). Left genital clasper thickened at base, bent at middle, and tapering to acute apex. Last abdominal segment not produced into long spines, knobs, or processes. Pronotum more or less constricted at middle and eyes relatively large.Macrolophus Fieber (type nubilus Fieber). Left genital clasper thickened at base, bent near middle, and flattened into a broad but apically tapering blade. Last abdominal segment not produced into long spines, knobs or processes. Eyes relatively small.Cyrtopeltis Fieber (type geniculata Fieber). Left genital clasper as in Macrolophus. Last abdominal segment roundly produced as a short, broad, upturned lobe posteriorly and with a prominent rounded knob on the left side of the segment. Eyes relatively large. This is apparently monotypic.Engytatus Reuter (type geniculatus Reuter). Left genital clasper as in Macrolophus or with the thickened basal portion much enlarged and extending beyond the point of origin of the bladelike arm (as in nicotianae). Last abdominal segment more or less strongly produced ventrally into an upturned process which branches into two arms apically. Eyes variable in size. Confusa Perkins and hawaiiensis Kirkaldy belong here. Geniculatus Reuter was a secondary homonym in Cyrtopeltis, where Reuter and Knight placed it. Hepce the name of the next oldest synonym, varians Distant, was used. According to the Banks and Caudell Code and the recommendations of the British Commission on Entomological Nomenclature, the name geniculatus may now be restored but the International Code is not so clear on this point.Gallobelieus Distant (type crassicornis Distant = tenuis Reuter). Left genital clasper abruptly elbowed and typically with the apical arm very long and tapering. Last abdominal segment produced ventrally into a more or less prominent, unbranched arm and with a second projection near base of clasper at least in the type species. I have collected another species of this genus on Luzon, and Knight's Marquesan species (B. P. Bishop Mus., Bull. 142: 173- 177, 1938) may belong here.

62. Lygus species.A single, badly damaged female, Guam, Fullaway (1183) may belong here. All of the tarsi are broken off and the apical portion of the membrane is gone. The specimen is dark brown with ochraceous basal margin of pronotum and base of cuneus. The antennae are relatively strongly incrassate, the vertex is margined behind, and the rostrum is short, though the head is so distorted that it is difficult to determine whether the rostrum would reach the intermediate coxae.

(Uploaded by Plazi for the IPBES Invasive Alien Species Assessment) Invasive fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is a species native to the Americas which has spread to Africa in 2016. This insect has been reported in Benin as a major pest of maize causing important economic losses and putting at risk food and nutritional security. This study evaluated the damage caused by this pest to maize in different cropping system and management practices. It also assessed predatory ants presence and diversity and their potential in controlling FAW. Results showed that 50% of farmers grow maize in a mixed cropping systems in association with sorghum, cassava and cowpea and also used biopesticides. FAW larval population and damage in maize fields varied accros villages. Surprinsingly FAW larval population was higher in maize field sprayed with insecticides than untreated field. Seven species of predatory ants were recorded in maize field. Ants' population was higher in untreated field (1043 ants per hectare) than treated field (806 ants per hectare). In the laboratory, ants species exhibits great predatory potential. Further studies are needed to discuss uses of ants in FAW management in Benin. © 2021, African Association of Insect Scientists.

This experimental study analyzes how uncertainty influences health-related decision making by increasing reliance on affective impulses. Using a randomized pre–post design with an induced uncertainty condition based on false cardiac feedback, the research examines physiological activation, decisional conflict, and affect-based choices. Results indicate that uncertainty enhances affect-driven decision making, highlighting the role of emotional processes in health-related judgments under ambiguous conditions.

O presente artigo busca analisar o poema “Quando for preciso” de Matheus Fernando Gomes de Azevedo, publicado em setembro de 2023 na Revista Ikebana. A metodologia empregada foi a análise de corpus, baseada na revisão de literatura específi ca. Os principais eixos teóricos adotados são: a análise do discurso de linha russa, a teoria estrutural e topográfi ca do aparelho psíquico e a fi losofi a da linguagem. Como resultados, pudemos observar uma riqueza estética complexa imbuída na estrutura e conteúdo do poema: o que evidencia seu valor literário enquanto uma produção contemporânea brasileira.
