Abstract
Diversity of fruit fly (Diptera: Tephritidae) species in French Guiana: their main host plants with associated parasitoids during the period 1994-2003 and prospects for management. Abstract -Introduction.This study was carried out in French Guiana, over ten years (1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003) by three institutions (SPV, FDGPC and CIRAD); it updates the current state of knowledge of Tephritidae (both Dacini and Toxotrypanini tribes) species present in this country.Materials and methods.The work was mainly conducted in inhabited areas (from the Brazilian border to the Surinamese border) where cultivated fruit crops are located.Specimens were obtained by adult trapping and fruit sampling in nearby orchards and at the edge of the rainforest.Trapping was done consistently for 10 years, while fruit sampling was a discontinuous activity.We present only the results for fruit sampling from three consecutive years (2001)(2002)(2003) in which a total of 880 kg from 45 fruit species in 22 plant families were collected.Results.Twenty-nine plant species from fourteen plant families were found to be hosts of twenty-one Anastrepha species and one Bactrocera species, Bactrocera carambolae Drew and Hancock.During this period, no specimen of Ceratitis capitata (Wiedemann) was collected in traps or fruit samples.We registered the main fruit trees which were hosts for B. carambolae and Anastrepha spp.Five hymenopterous parasitoid species were identified.Among them, Diachasmimorpha longicaudata (Ashmead) (Hymenoptera, Braconidae) is an exotic species and was introduced into French Guiana in collaboration with Brazilian authorities (EMBRAPA) in 2000 and 2001 within the framework of a classical biological control program.Conclusion.Our data provide baseline information about the tephritid species of economic importance present in French Guiana and assist in developing potential future control programs of both the B. carambolae and Anastrepha species in the Amazon Basin.These preliminary results are discussed in the light of their implication for rainforest conservation efforts and also evolutionary relationships between fruit flies and their hosts.French Guiana / fruit trees / host plants / fruit-damaging insects / data collection / Tephritidae / Braconidae / Bactrocera carambolae / Anastrepha Diversité des espèces de mouches des fruits (Diptera : Tephritidae) présentes en Guyane française : leurs principales plantes-hôtes et leurs parasitoïdes durant la période 1994-2003, et perspectives de lutte. Résumé -Introduction.Cette étude s'est déroulée en Guyane française durant dix ans (1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003) grâce à trois institutions (SPV, FDGPC, CIRAD) ; elle apporte sa contribution à un inventaire des espèces de Tephritidae (Dacini and Toxotrypanini) dans ce pays.Matériel et méthodes.Cet inventaire concerne les zones habitées de la Guyane française de la frontière brésilienne à la frontière surinamienne et concerne les localités hébergeant des cultures fruitières.Les Tephritidae ont été obtenues par piégeage des adultes et échantillonnages de fruits autour des vergers et en bordure de la forêt pluviale.Le piégeage a duré globalement une dizaine d'année tandis que les échantillonnages de fruits ont été effectués de façon discontinue.Nous présentons les résultats de trois années consécutives ( 2001 à 2003) durant lesquelles un total de 880 kg de fruits, avec 45 essences fruitières représentant 22 familles, a été récolté.Résultats.Vingt neuf espèces fruitières appartenant à quatorze familles sont les hôtes de vingt et une espèces d'Anastrepha et d'une espèce de Bactrocera, Bactrocera carambolae Drew and Hancock.Durant cette période, aucun specimen de Ceratitis capitata (Wiedemann) n'a été capturé dans les pièges ou n'a émergé des récoltes de fruits.Nous présentons les principales espèces fruitières hôtes de B. carambolae et Anastrepha spp.Nous avons identifié cinq espèces d'hyménoptères parasitoïdes.Parmi elles, Diachasmimorpha longicaudata (Ashmead) (Hymenoptera, Braconidae) est une espèce exotique qui a été introduite en Guyane française en 2000 et 2001 en collaboration avec les autorités brésiliennes (EMBRAPA), dans le cadre d'un programme de lutte biologique.Conclusion.Ces observations préliminaires peuvent apporter des informations basiques dans l'éventualité de la reprise des programmes de lutte contre B. carambolae et contre les principales espèces d'Anastrepha dans le bassin amazonien.Ces résultats sont discutés dans l'optique de leur valorisation pour la protection des forêts primaires, mais également de l'évolution des relations insectes-plantes.Guyane française / arbre fruitier / plante hôte / insecte déprédateur des fruits / collecte de données / Tephritidae / Braconidae / Bactrocera carambolae / Anastrepha

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
