Abstract

GONZALES, Manuel et al. Adult population dynamics of the bolivian fruit flies Anastrepha sp. (Diptera: Tephritidae) at Municipality Coroico, Department of The La Paz, Bolivia. J. Selva Andina Res. Soc. [online]. 2011, vol.2, n.2, pp.2-12. ISSN 2072-9294.

The investigation was carried out in Paco (1603 msnm) communities, it Marca (1511 msnm) and Capellania (1720 msnm), of the Municipality of Coroico, department of La Paz, Bolivia. In orchards frutícolas semicomerciales, they settled 15 traps distributed McPhail in a similar way among areas, five for community, sampling" "points. The censuses were carried out with an interval of 15 days, they were identified and they quantified the mature flies of the fruit. For the captures of the individuals, they settled the traps McPhail, using the attractive (Buminal) one and as conserving borax. The traps were distributed in representative parcels, having as main cultivations, orange, mandarin, grapefruit, guava and avocado. The identification taxonómica of the captured species was carried out in the laboratory of the National Program of Control of Flies of the fruit (PROMOSCA), clerk of the National Service of Agricultural Sanity and Alimentary (SENASAG) Inocuidad. 1210 mature flies of the fruit were captures, those that grouped for species, sex, capture dates and community, corresponding to the seven carried out censuses. The species of Anastrepha fraterculus (Wiedeman) were identified, Anastrepha striata Schiner, Anastrepha serpentine (Wiedeman), Anastrepha sp, Ceratitis capitata (Wiedemann), Blepharoneura sp Loew, Hexaresta sp Hering, Hexachaeta sp Loew, Tomoplagia sp Coquillett, Tetreuaresta sp Hendel, being that of more presence Anastrepha fraterculus (Wiedeman) with 818 and Ceratitis capitata (Wiedemann), with 354. The temperature and presence of spices put up frutícolas of flies of the fruit in maturation state explain the observed fluctuations.
