i5K Comments for Bactrocera oleae
Bactrocera oleae, the olive fruit fly (OLF), is an agricultural pest of global significance. This tephritid fruit fly has invaded the majority of countries where olives are grown, including a recent invasion of the United States in the late 1990's. Despite the sequencing of its mitochondrial genome, the country of origin of the OLF remains highly debated. Over 90% of olives are infested when OLF is present in a grove, thus control is a concern for growers. OLF has been a target for sterile insect technique, but difficulties remain in mass rearing the fly. Long-term reared laboratory strains have shorter lifespans and are not as competitive as wild flies. Instead, insecticides remain the primary method for control though insecticide resistance is a growing problem. Finally, the OLF associates primarily with one beneficial endosymbiont, Candidatus Erwinia dacicola, though other bacteria are transiently associated with the fly. C. E. dacicola is unusual in that it is one of the few non-pathogenic bacteria to transition between intracellular and extracellular lifestyles during fly development. The genome of this symbiont has been sequenced and is currently being examined. Sequencing the insect genome would allow for a more comprehensive understanding of how the insect and bacterium interact. Additionally, tephritid fruit flies are global agricultural pests. Ceratitis capitata, the Mediterranean fruit fly, has already been sequenced and might be able to be used as a scaffold. Approximately 5 labs in the U.S., Italy, Israel, and Greece work on the olive fly symbiosis. More than 20 labs across the world conduct work on the pest management aspect of this fly. A strong network of hundreds of investigators work on closely related species of tephritid fruit flies. High quality, freshly isolated genomic DNA can be easily obtained from a variety of laboratory strains and wild collected animals from a variety of populations. Anne Estes
