TI  - Infestation of guava by Anastrepha fraterculus (Diptera: Tephritidae): preferred ripening stages and infuence of fruit peel coloration
AB  - The current study aimed to verify the preferred guava fruit ripening stage for egg laying by Anastrepha fraterculus (Diptera:Tephritidae) and to determine the infuence of peel coloration of the fruits of 2 cultivars on infestation. Te cultivars used were Palumaand Século XXI. Te infestation level was evaluated in cages, considering 2 conditions: multiple-choice and nonchoice tests. Teinfestation levels of A. fraterculus difered between the green and the green-ripe stages in the multiple-choice test. In Paluma fruitswith the nonchoice test, the infestation was highest during the ripe stage. Tere were no diferences in infestation levels of A. fraterculusbetween the green and the green-ripe stages in Século XXI. In general, the green-ripe and the ripe stages were preferred for egg layingby A. fraterculus. In Paluma fruits there were signifcant correlations of infestation levels of A. fraterculus with luminosity (L) andchromaticity (C) in the nonchoice assay. In Século XXI fruits there was a signifcant correlation of infestation levels of A. fraterculus withcolor angle (h ) in the nonchoice assay. No correlation was found between theses parameters in the multiple-choice test.
