Resumo: The generation of information about the potential of alternative tactics in the control of fruit flies has attracted a growing interest, both producing and researchers. This research aimed to evaluate the effects of guava cultivars and substances from plant metabolism on biological parameters of Anastrepha fraterculus (Wied., 1830) (Diptera: Tephritidae) and Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae). The study was conducted in the Laboratory of Plant Resistance, Department of Plant Protection, Faculty of Agricultural Sciences and Veterinary Medicine - UNESP. The guava fruits were obtained from Company Val fruits, located in “Vista Alegre do Alto” - SP. The fruit-flies and parasitoids were derived from rearing on artificial diet in the laboratory Radioentomologia - CENA. 6 bioassays were conducted: 1- Determining the maturity stage of guava fruits preferred for egg-laying of A. fraterculus, 2- No preference for egg-laying of A. fraterculus fruits of the guava cultivars, 3- Effect of natural products used in guava fruit on egg-laying of A. fraterculus, 4- Association of the effects of the fruits of guava cultivars and natural products on parasitism of D. longicaudata, 5- Antibiosis test of fruit varieties of guava and on A. fraterculus and 6- Effect of extrinsic resistance of cultivars of guava fruit on the parasitoid D. longicaudata. Fruits were treated with the following products: neem oil, essential oil from fennel and citronella, and controle. Tests with and without choice has been made. The results were subjected to analysis of variance (ANOVA), means were compared by Tukey test (P = 0.05). A. fraterculus female prefer stadiums semi-ripe and ripe for egg-laying. The Século XXI cultivar is more susceptible to attack by A. fraterculus. Products which showed the lowest infestation rates were oils of neem and citronella, from the 1.0% concentration. The fruits when ...
