245 0 0 a| Interaction of Beauveria bassiana (Hypocreales: Cordycipitaceae) and Coptera haywardi (Hymenoptera: Diapriidae) for the management of Anastrepha obliqua (Diptera: Tephritidae)
520 1 _ a| Background: Each natural enemy exerts different control effect on the pest populations, therefore it is estimate that if two or more natural enemies are combined, can increase the mortality of the pest, where the interactions may be synergistic, additive or antagonistic. Several studies showed that both the parasitoid Coptera haywardi (Ch) and the entomopathogenic fungus Beauveria bassiana (Bb) have favorable attributes for the control of fruit flies at the pupa and adult stages, respectively. Based on the last, and with the goal of developing better biological control strategies, the interaction of B. bassiana and C. haywardi was evaluated for the management of A. obliqua. Methods: Initially under laboratory conditions the effect of the application of the fungus (dry conidia and spray) was evaluated from the moment the larva entry to soil. Subsequently, under semi-controlled conditions, using Plexiglas cages (30cm3) as experimental units, we evaluated the mortality of A. obliqua when the two natural enemies were integrated, comparing with the mortality in the untreated control and when only one natural enemy was used (parasitoid or fungus).
520 1 _ a| Results: The application of the fungus to the soil by dry conidia, under laboratory conditions, caused a 40% mortality in A. obliqua adults. In semi-controlled conditions, the application of the fungus to the soil did not affect the emergence of the flies, and adult mortality was 7.7% when Ch and Bb were used, compared to 21.2% when only Bb was applied. The parasitism percentage of Ch was not affect when it was applied together with Bb (68.6%) comparison when acting in solitaire (68.4%). Parasitoids mortality caused for Bb did not exceed 8%. The analysis of data with multiple decrements lifetable, showed that the use of the two natural enemies caused a death fraction in the fly of 0.88. However, this did not exceed the fraction of death caused when the parasitoid was released alone (0.89). When only the fungus was applied to the soil, the mortality fraction was 0.23. Conclusions: The interaction of these two natural enemies did not present synergistic or additive effects, but neither was it antagonistic, since Bb does not affect the action of Ch. Nevertheless, it is recommend to test this interactions under field conditions to corroborate these findings.

"Background: Each natural enemy exerts different control effect on the pest populations, therefore it is estimate that if two or more natural enemies are combined, can increase the mortality of the pest, where the interactions may be synergistic, additive or antagonistic. Several studies showed that both the parasitoid Coptera haywardi (Ch) and the entomopathogenic fungus Beauveria bassiana (Bb) have favorable attributes for the control of fruit flies at the pupa and adult stages, respectively.
