However, it is likely that under this specific name several biological species may be contained, the correct identification of which is essential for effective use in control programs. In this paper, three populations (DLA, DLB and DLBB) of D. longicaudata designated according to geography and/or natural hosts were reared in the same laboratory. They were tested for reproductive compatibility and characterized by morphometric analyzes. Forced-contact mating technique showed either complete lack of inter-population reproductive compatibility or the production of rare, sterile female offspring. The three populations, indistinguishable on the basis of morphological characters alone, were readily identified by the geometry of the wing. Results strongly suggest that the DLA, DLB and DLBB are distinct biological species, and highlight the usefulness of wing geometry to distinguish them. specialized Diachasmimorpha longicaudata Thailand Cryptic species Crossing experiments Morphometrics 076 51 1 191-197 2009 1049-9644 https://www.documentation.ird.fr/hor/fdi:010049240 10.1016/j.biocontrol.2009.06.011 1049-9644 [F B010049240] https://www.documentation.ird.fr/hor/fdi:010049240 https://www.documentation.ird.fr/intranet/publi/2010/02/010049240.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2010-03-10 2017-08-23 fdi:010049240 fre
