Figs. 15–21 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. 15–21. Damage symptoms of bamboo shoots attacked by I. burmensis. 15, Tip of an unaffected Melocalamus compactiflorus bamboo shoot. 16, Tip of a Melocalamus compactiflorus bamboo shoot infested by I. burmensis. The leaves of the upper internodes have started to wither. 17, The apical internodes have dropped down to the ground, but the I. burmensis internode is still attached to the bamboo shoot. A part of the internode sheath was removed in order to show the location of the bud, the zone of intercalary growth and the predetermined breaking point. 18, The newly emerged branches at the base of the I. burmensis-internode have displaced the internode sheath. Most branches are not depicted in order to show the exit hole above the predetermined breaking point. 19, The I. burmensis internode has cracked at the level of the exit hole and dangles at the tip of the bamboo shoot. The puparium is still protected by the torn off vascular fibres. 20, The apical part of the I. burmensis-internode has dropped to the ground. The basal stump of the internode remains attached at the tip of the bamboo shoot and harbours the puparium. 21, Longitudinal section of the enlarged basal part of an I. burmensis-internode showing the location of the puparium. b = branch; bb = branch bud; cs = culm sheath; eh = exit hole; ii = I. burmensis-internode; n = node; p = puparium; pbp = predetermined breaking point; sb = sheath blade; vf = vascular fibres; zig = zone of intercalary growth.
Figs. 8–14 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. 8–14. Damage of bamboo shoots caused by I. burmensis, and pupariation. 8, Basal part of an I. burmensis internode, early stage of infestation. The culm sheath was removed to show the branch bud, the zone of intercalary growth and the predetermined breaking point of the internode. 9, The apical part of the bamboo shoot has fallen down, but the I. burmensis-internode is still attached to the bamboo shoot. The emerging side branches have pushed away the culm sheath from the internode wall. 10, I. burmensis internode with side branches largely removed in order to show the slit-like exit hole. 11, The I. burmensis-internode has cracked at the level of the exit hole (above the predetermined breaking point). The exposed internode cavity is filled with torn off, compressed vascular fibres, which protect the puparium. 12, The cracked upper part of the I. burmensis-internode has dropped to the ground. The puparium rests inside the stump of the I. burmensis internode at the tip of the bamboo shoot. 13, I. burmensis puparium stuck in the basal part of the internode. The internode was broken at the predetermined breaking point in order to show the protruding puparium. 14, I. burmensis puparium stuck in the upper part of the internode cavity, anterior end on right hand side. as = anterior spiracle; bb = branch bud; cs = culm sheath; eh = exit hole; ii = I. burmensis-internode; p = puparium; pbp = predetermined breaking point; vf = vascular fibres; zig = zone of intercalary growth.
