Resumo: | Differences in susceptibility to viruses in plants may be partially explained by the insect vector probing behavior and by the presence of phenolic compounds, which are often associated with defense strategies. This study aimed at detecting barriers that may difficult the probing activity of the Dysmicoccus brevipes (Pseudococcidae) pineapple mealybug, a vector of the pineapple mealybug wilt-associated virus, as well as evaluating the phenolic content of plants, in order to verify any possible relationship with the probing behavior, by using the electrical penetration graphs (EPG) technique. Seedlings of 'Smooth Cayenne' and 'Pérola' pineapple cultivars were used in the experiments. Only 28 % and 21 % of the mealybugs reached the phloem of the 'Smooth Cayenne' and 'Pérola' cultivars, respectively, over 16 h of recording, with an average of 9 h to reach the phloem vessels. The xylem phase was extended in both cultivars and represented approximately 31 % ('Smooth Cayenne') and 44 % ('Pérola') of the recording time. The phenolic contents of both cultivars were similar. |

Objetivou-se detectar barreiras que dificultem a alimentação da cochonilha Dysmicoccus brevipes (Pseudococcidae), vetora do vírus pineapple mealybug wilt-associated em abacaxizeiro, bem como analisar o conteúdo de fenóis dessas plantas, a fim de verificar a possível existência de correlação com a conduta alimentar, por meio da técnica de Electrical Penetration Graphs (EPG). Utilizaram-se as cultivares 'Smooth Cayenne' e 'Pérola'. Somente 28 % e 21 % das cochonilhas atingiram o floema nas cultivares 'Smooth Cayenne' e 'Pérola', respectivamente, durante as 16 h de registro, e, em média, levaram 9 h para alcançar os vasos floemáticos. A fase no xilema foi extensa em ambas as cultivares e representou, aproximadamente, 31 % ('Smooth Cayenne') e 44 % ('Pérola') do tempo registrado. O conteúdo de fenóis não diferiu entre as cultivares.Universidade Federal de Goiás, Escola de Agronomia e Engenharia de Alimentos2018-12-05T11:56:57Z2018-12-05T11:56:57Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSANTA-CECÍLIA, L.
