ABSTRACT Citriculture is a growing industry in Pará state, Brazil, but information regarding fruit flies and their associated parasitoids in this region is lacking. To address this gap in knowledge, we collected oranges (Citrus sinensis), lime oranges (C. sinensis), common sweet limes (C. limettioides), citrons (C. medica) and mandarins (C. reticulata). We recorded field infestation by Anastrepha obliqua in C. sinensis under natural conditions for the first time in the study region, and a tritrophic relationship between C. sinensis, A. obliqua, and the parasitoids Opius bellus and Asobara anastrephae was identified.

Tephritid Fruit Flies

Tephritid fruit flies require protein for sexual and gonotrophic development. Food-based lures are therefore widely used in strategies to detect and control fruit flies in the Tephritidae family. However, these baits are attractive to a broad range of insect species. We therefore sought to identify volatiles detected by the fly antennae, with the goal to compose lures that more specifically target tephritids. Using gas chromatography-coupled electroantennographic detection (GC-EAD) we screened for antennal responses of four important tephritid species to volatile compounds from five commercially available protein-based baits. Antennal active compounds were reconstituted in synthetic blends for each species and used in behavioral assays. These species-based blends were attractive in olfactometer experiments, as was a blend composed of all antennally active compounds from all the four species we observed (tested only in Bactrocera dorsalis, Hendel). Pilot field tests indicate that the blends need to be further evaluated and optimized under field conditions.

The objective of the research were to investigate level parasitization, immature development period, longevity of adult parasitoids, along with number of progeny and parasitoid sex of Psyttalia sp. attacking larvae of Bactrocera dorsalis. This experiment was conducted in Laboratory of Entomology, Department Plant Pest and Diseases Faculty of Agriculture, Sriwijaya University from March to September 2007. The result showed that the average level of parasitization of Psyttalia sp. reached 24.24%. The highest one was 30% and the lowest was 16.7%. The immature development period of Psyttalia sp. ranged from 24-31 days with average 27.5 days. Longevity of imago parasitoids which stored at 5 0C was 14.1 days. In the research, the progeny of parasitoids which produced was females with percentage of females reached 59.99% and percentage of males reached 39.99%.Keywords: fruit flies, Bactrocera dorsalis, parasitoid, Psyttalia sp.
