É relatada a ocorrência de Aphis spiraecola Patch, 1914 (Hemiptera: Aphididae: Aphidini) e Pentalonia nigronervosa Coquerel, 1859 (Hemiptera: Aphididae: Macrosiphini) atacando Xanthosoma sagittifolium (L.) Schott (Alismatales: Araceae) no Brasil. Devido ao ataque dos pulgões, as folhas da planta ornamental apresentaram áreas esbranquiçadas, principalmente ao redor da nervura central, e amplas áreas cobertas com secreção açucarada liberada pelos insetos. Junto com os pulgões foram identificados um predador, Cycloneda sanguinea (L., 1763) (Coleoptera: Coccinellidae), um parasitoide, Aphidius colemani Viereck, 1912 (Hymenoptera: Braconidae), e um hiperparasitoide, Syrphophagus aphidivorus (Mayr, 1876) (Hymenoptera: Encyrtidae). Este é o primeiro registro de associação hospedeira entre X. sagittifolium e A. spiraecola no mundo.

Aphids associated with papaya plants were collected from two sites in Puerto Rico (Isabela and Corozal) and three farms in Homestead, Florida. Between the two regions, Florida and Puerto Rico, twenty-one species of aphids from 12 genera were identified: Aphis sp., Aphis illinoisensis Shimer, Aphis spiraecola Patch, Aphis gossypii Glover, Aphis craccivora Koch, Aphis iddletonii (Thomas), Aphis nerii Boyer de Fonscolombe, Hyperomyzus carduellinus (Theobald), Hysteroneura setariae (Thomas), Lipaphis pseudobrassicae (Davis), Picturaphis sp., Pentalonia nigronervosa Coquerel, Schizaphis graminum (Rondani), Sarucallis kahawaluokalani (Kirkaldy), Shinjia orientalis (Mordvilko), Schizaphis rotundiventris (Signoret), Toxoptera citricida (Kilkardy), Toxoptera aurantii (Boyer de Fonscolombe), Tetraneura nigriabdominalis (Sasaki), Uroleucon ambrosiae (Thomas), and Uroleucon pseudoambrosiae (Olive). The number of species was greater in Florida (n = 14) than in Puerto Rico (n = 11). Differences among species were also found between sites in Puerto Rico, with 10 species in Corozal and six in Isabela. Only one species, A. illinoisensis, was common at all sites sampled, whereas three additional species, A. spiraecola, A. gossypii, and A. craccivora were collected in both the Corozal, Puerto Rico, and the Florida areas. The difference in species composition between Puerto Rican sites (Corozal and Isabela) and between localities (Florida and Puerto Rico) is probably associated with differences in agricultural crops or weeds present in each region.

O objetivo deste trabalho foi verificar a diversidade de afídeos (Hemiptera: Aphididae) na cultura do algodoeiro (Gossypium hirsutum L.) no município de Campo Verde (MT). Os afídeos foram amostrados diretamente nas plantas e através de armadilhas tipo Moericke. As amostragens foram realizadas a cada dois dias, até 60 dias após a germinação das plantas. A espécie Aphis gossypii Glover prevaleceu nas amostragens realizadas sobre as plantas. Formas aladas, de ocorrência acidental na cultura, tais como Aphis spiraecola Patch e Rhopalosiphum padi (Linnaeus) também foram observadas. Com as armadilhas tipo Moericke foram capturados 2280 afídeos alados, pertencentes a 13 espécies: R. padi (52,6% do total), A. spiraecola (26,4%), A. gossypii (8,9%), Rhopalosiphum maidis (Fitch) (5,3%), Geopemphigus floccosus (Moreira) (3,1%), Uroleucon ambrosiae (Thomas) (1,5%), Rhopalosiphum rufiabdominalis (Sasaki) (1,3%), Myzus persicae (Sulzer) (0,4%), Sipha flava (Forbes) (0,3%), Pentalonia nigronervosa Coquerel, Tetraneura nigriabdominalis (Sasaki), Lizerius melanocallis (Quednau) e Toxoptera citricidus (Kirkaldy) (0,1% cada uma). Nas amostragens diretamente sobre as plantas foram observados ápteros e alados de A. gossypii e alados de A. spiraecola e R. padi. Nas armadilhas tipo Moericke, as principais espécies capturadas foram R. padi, A. spiraecola, A. gossypii e R. maidis.

Os afídeos são importantes pragas em citros como vetores de vírus fitopatogênicos. O objetivo do trabalho foi avaliar a diversidade de espécies de afídeos alados e a ocorrência estacional dos afídeos em um pomar de citros localizado em Taiúva, SP. Para as coletas de afídeos foram utilizadas armadilhas do tipo bandejas amarelas com água e placas adesivas amarelas. Foram realizadas quatro amostragens semanais em cada estação climática, durante o ano agrícola de 2004/2005. Foram capturados exemplares de afídeos das espécies: Aphis gossypii Glover, Aphis spiraecola Patch, Toxoptera citricida Kirkaldy e Toxoptera aurantii (Boyer de Fonscombe), Rhopalosiphum maidis (Fitch), Pentalonia nigronervosa Coquerel, Uroleucon ambrosie (Thomas) e Acyrthosiphon bidenticola Smith. As espécies A. spiraecola e T. citricida foram as mais abundantes, sendo caracterizadas como espécies comuns em todo o período avaliado. Coletaram-se mais afídeos alados no outono/2004, em relação às demais estações e maior quantidade e diversidade de espécies de afídeos foi obtida em bandejas com água.

AbstractThis study aims to provide a simple framework to identify wild food plants with potential for popularization based on local knowledge and perception. To this end, we also characterized the distribution of this knowledge in the socio-ecological system. We developed the study in the rural settlement Dom Hélder Câmara in northeastern Brazil. The species with the greatest potential for popularization considering the attributes accessed from local knowledge and perception were Psidium guineense Sw., Genipa americana L., Xanthosoma sagittifolium (L.) Schott and Dioscorea trifida L.f. However, the high variation in local knowledge on wild food plants suggests that species that are not frequently cited can also be promising. The absence of age or gender-related knowledge patterns indicates that studies for prospecting wild food plants in similar socioecological contexts need to reach the population as a whole, rather than focusing on a specific group.

Xanthosoma sagittifoliumSchott is a herb of the Araceae family, popularly known as taioba, which is consumed as food in some regions of Brazil, Africa, and Asia. This species has already been evaluated for the antifungal activities. However, based on its potential antitumor activity, the present study further aimed to examine the antitumor, as well as chelation, activity ofX. sagittifoliumleaf extract. Results showed that hydroethanolic extract ofX. sagittifoliumleaves (HEXs-L) exhibits cytotoxic effects against the immortalized line of human T-lymphocytic (Jurkat) and myelogenous (K562) leukemia cells, but not nontumor RAW 264.7 macrophages or NIH/3T3 fibroblasts. HEXs-L inhibited 50.3% of Jurkat cell proliferation, reducing by 20% cells in G2/M phase, but increasing cells in sub-G1 phase, thereby inducing apoptosis by 54%. In addition, HEXs-L inhibited NO production by 59%, as determined by Griess reaction, and chelated 93.8% of free Fe(II), as demonstrated by ferrozine assay. Phytochemical studies were carried out by ESI-MS, identifying apigenin di-C-glycosides as major compounds. Overall, this work revealed that leaf extract ofXanthosoma sagittifoliumpresented chelating activity andin vitroantitumor activity, arresting cell cycle and inducing apoptosis of leukemia cells, thus providing evidence that taioba leaves may have practical application in cancer therapy.
