Resumo: Aphids cause great damage to cultivated crops. With the aim of aid managing methods, biological properties subject to heavy selection were studied in the three south Brazilian species Schizaphis graminum, Sitobion avenae and Rhopalosiphum padi (Homoptera: Aphididae). Changes in embryonic outer morphology were analysed under contrast phase microscope and eight stages were described. The embryonic period terminated after 20, 24 and 26 hours; the longevity (expressed in number of days from nymph to adult death) was of 31.13 ± 2.79, 29.73 ± 1.5, 25.13 ± 3.22 and the fecundity (number of nymphs per adult aphid) was of 66.87 ± 8.05, 31.67 ± 3.75, 49.53 ± 6.26, respectively. When the fecundity/longevity ratio was compared it was concluded that S. graminum was the most dangerous to wheat, and BR-35 wheat strain was the most susceptible to aphid control. The differences in embryonic time and morphological characteristics can be used to classify the three species.

Com o objetivo de subsidiar programas de controle, propriedades biológicas sujeitas a forte pressão de seleção foram estudadas nas espécies sul-brasileiras Schizaphis graminum, Sitobion avenae e Rhopalosiphum padi (Homoptera: Aphididae). Mudanças na morfologia externa dos embriões foram analisadas sob microscópio de contraste de fase, e oito estágios foram descritos. O período embrionário terminou com 20, 24 e 26 horas; a longevidade (expressa em número de dias desde ninfa até a morte do indivíduo adulto) foi de 31,13 ± 2,79; 29,73 ±1,5; 25,13 ± 3,22 e a fecundidade (número de ninfas por afídeo adulto) foi de 66,87 ± 8,05; 31,67 ±3,75; 49,53 ±6,26, respectivamente. Quando se comparou o quociente fecundidade/longevidade, concluiu-se ser S. graminum o mais prejudicial ao trigo, e a linhagem BR-35, a mais suscetível ao controle de afídeos. As diferenças no tempo e características morfológicas embrionárias podem ser usadas para classificar as três espécies.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRubín de Celis, VerônicaGassen, DirceuValente, Vera LúciaKalisz de Oliveira, Alice1997-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4615Pesquisa Agropecuaria Brasileira; v.32, n.2, fev. 1997; 137-145Pesquisa Agropecuária Brasileira; v.32, n.2, fev. 1997; 137-1451678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/4615/7085info:eu-repo/semantics/openAccess2015-02-25T19:58:37Zoai:ojs.seer.sct.embrapa.br:article/4615Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-02-25T19:58:37Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
