Figs. 1–7 in Biology And Description Of The Third Instar Larva And Puparium Of Ichneumonopsis Burmensis Hardy (Diptera: Tephritidae: Dacinae: Gastrozonini), A Bamboo-Breeding Fruit Fly From The Oriental Region

Figs. 1–7. Adults, habitat and development of I. burmensis-larvae. 1, Habitus of I. burmensis female. 2, Bamboo stand of M. compactiflorus in north Thailand at the edge of a field in November. The bamboo shoot in the front was damaged by a larva of the weevil Cyrtotrachelus sp. and the apical part of the main stem has dropped to the ground (large arrow points to the stump of the main stem). One of the resulting side branches of the main stem is infested by an I. burmensis larva (ii). The large side branch on the left has taken over the function of the main stem. 3, Cross-section through an M. compactiflorus internode near the apex of the bamboo shoot (diameter: 7 mm). The internode cavity contains white pith. 4, Apical part of an infested bamboo shoot of M. compactiflorus. The arrow points to the internode containing an I. burmensis larva. The upper internodes are dead but still attached to the bamboo shoot. 5, I. burmensis larva feeding on the white pith inside a bamboo internode (diameter of the internode cavity: 3–4 mm). 6, Bamboo fibres, ca. 5–7 cm long, recently torn off by the larva. 7, Lateral cut through an I. burmensis-internode (base of the internode on the left). The larva has eaten up about half of the white pith in the basal part the internode cavity and has freshly pupated at the base of the internode. Note the thin bamboo wall at the level of the exit hole. Most of the torn off vascular fibres have been removed in order to show the puparium. They filled the cavity beween the puparium and the "vf" arrow. eh = exit hole; bp = bamboo pith; bb = branch bud; ii = I. burmensis-internode; p = puparium; vf = vascular fibres.
