[Emergy analysis of four typical planting modes in Karst faulted basins of Yunnan Province, China.].

Accurate evaluation of typical cropping patterns in faulted basins can provide scientific guidance for planting in the area. The planting modes of marigold, pomegranate, pomegranate+grass+sheep in Mengzi City of Yunnan Province were compared with the traditional corn planting mode. The ecological benefits and economy benefits of these rocky desertification control modes were analyzed by the method of emergy analysis.

[Ultrastructure of Ericerus pela (Chavannes) nymph mouthparts and ecological adaptations].

The ultrastructure of nymph mouthparts of the Chinese white wax scale (CWWS), Ericerus pela, consists internally of the crumena, tentorium, the stylet bundle, comprised of two mandibular stylets and two maxillary stylets, and the external clypeolabral shield, labium and sensilla. The mouthpart morphology and structures of the female nymphs are similar to the male. The mouthparts of CWWS have significantly different features in comparison to aphids and other coccids.
