Transmission of Passion fruit woodiness virus by Aphis gossypii (Glover) (Hemiptera: Aphididae) and colonization of Passion flower by the vector

Avaliou-se a transmissão de Passion fruit woodiness virus (PWV) por Aphis gossypii (Glover). Em dois experimentos independentes, o afídeo transmitiu o PWV para maracujazeiros com taxas de 75% e 100%, ao se depositarem oito e doze afídeos virulíferos por planta, respectivamente. No final dos testes, observaram-se, em algumas plantas de maracujá, formas ápteras e ninfas de A. gossypii, sugerindo a colonização dessas plantas pelo afídeo. Esse parece ser o primeiro relato da colonização de Passiflora edulis f. flavicarpa (Deneger) por uma espécie de afídeo.The transmission of Passion fruit woodiness virus (PWV) by Aphis gossypii (Glover) was evaluated. In two independent experiments, A. gossypii transmitted PWV to passion fruit plants at the rates of 75% and 100%, when eight and twelve viruliferous aphids were deposited by plant, respectively. At the end of the tests, nymphs of A. gossypii were observed in some of the passion fruit plants, suggesting that the aphid species was colonizing the plants. This seems to be the first report of Passiflora edulis f. flavicarpa (Deneger) colonization by a species of aphid
