tailieunhanh - Infestation of guava by Anastrepha fraterculus (Diptera: Tephritidae): Preferred ripening stages and influence of fruit peel coloration

The current study aimed to verify the preferred guava fruit ripening stage for egg laying by Anastrepha fraterculus (Diptera: Tephritidae) and to determine the influence of peel coloration of the fruits of 2 cultivars on infestation. The cultivars used were Paluma and Século XXI. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2015) 39: 1-9 © TÜBİTAK doi: Infestation of guava by Anastrepha fraterculus (Diptera: Tephritidae): preferred ripening stages and influence of fruit peel coloration 1, 1 2 Flávia Queiroz DE OLIVEIRA *, Arlindo Leal BOIÇA JÚNIOR , Maria de Lourdes ZAMBONI COSTA , 3 2 1 Jacinto de Luna BATISTA , Karen Zamboni COSTA , Júlio Marcos MELGES WALDER 1 Faculty of Agriculture and Veterinary Science, São Paulo State University, Jaboticabal–SP, Brazil 2 Center for Nuclear Energy in Agriculture (CENA), University of São Paulo, Piracicaba-SP, Brazil 3 Federal University of Paraíba – UFPB, Areia-PB, Brazil Received: Accepted: Published Online: Printed: Abstract: The current study aimed to verify the preferred guava fruit ripening stage for egg laying by Anastrepha fraterculus (Diptera: Tephritidae) and to determine the influence of peel coloration of the fruits of 2 cultivars on infestation. The cultivars used were Paluma and Século XXI. The infestation level was evaluated in cages, considering 2 conditions: multiple-choice and nonchoice tests. The infestation levels of A. fraterculus differed between the green and the green-ripe stages in the multiple-choice test. In Paluma fruits with the nonchoice test, the infestation was highest during the ripe stage. There were no differences in infestation levels of A. fraterculus between the green and the green-ripe stages in Século XXI. In general, the green-ripe and the ripe stages were preferred for egg laying by A. fraterculus. In Paluma fruits there were significant correlations of infestation levels of A. fraterculus with luminosity (L) and chromaticity (C) in the nonchoice assay. In Século XXI fruits there was a significant correlation of infestation levels of A. fraterculus with color angle (h) in the nonchoice assay. No correlation was .
