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.

Breeding biology of two populations of Chinese penduline tits
<p>The phenotypes and breeding behavior in one species may be different between populations. The local environments, social interactions can all lead to some variations in life history. The thorough investigations of breeding biology over populations can provide insights for us to understand the evolution and diversifications of breeding systems and phenotypic traits from multiple perspectives other than drawing monotonous associations between a factor and a trait. In this study, we explored two Chinese penduline populations, Liaohekou (LHK) and Xianghai (XH), both in the northeast of China located 550 km away from each other. A comparative study of the breeding biology was carried on in the two populations. We found that the climate has no obvious difference in these two populations but has different habitats. Nest emergence and egg-laying were earlier in the more northern population XH. Males in XH has a lower chance of pairing up with a female and exhibit mainly biparental care pattern instead uniparental care that we reported in LHK. The chick fledgling success in the biparental care nests was higher than in the uniparental care nests in XH, but no difference to the uniparental care nests in LHK. Besides, the penduline tits in the two populations were also significantly different in their wing length, tail length and beak shape. These incongruences suggested different food availability, adult sex ratio and migration distances of the two populations. Future studies should experimentally investigate the joint influences of breeding perspectives on the evolution of parental care and mating system.</p>
