| Contribution to the study of Cicadellidae in some agro-ecosystem Saharan - Case of the area of Ouargla | |
| 2017 Full Book | |
This work concerns a contribution to the study of HomoptŠres and more precisely Cicadellidae in some Saharan agro-ecosystems to Ouargla. Within this area, an inventory of the arthropods according to the orders and species of Cicadellidae are carried out over one 8 months period (since September 2016 until April 2017) while using three methods of trappings (colored traps, mowing, luminous traps). These last methods are applied in four stations, which made it possible to count 16 orders (Isopoda, Collembola, Araneae, Scorpionida, Thysanoptera, Mantoptera, Orthoptera, Homoptera, Hemiptera, Hymenoptera, Coleoptera, Neuroptera, Lepidoptera, Diptera, Embioptera and Nevroptera). The order of HomoptŠres is inventoried the most with 17 species divided into 7 pennies families. The total richness highest (S = 25 species) is noted for the method of colored traps. Under family Agalliinae (AR = 23,9 %) is captured thanks to this last method. The fourth station is richest in under family of Cicadellidae (S = 6 pennies families). The species most captured in this station is _Recilla coronifera _(AR = 10,1 %). The values of the diversity of Shannon-Weaver vary between 1,81(bits) and 3,16 (bits). Whereas the values of the equitability tend towards 1 (E > 0,75), which reflects a tendency towards balance between manpower of Cicadellidae trapped in the various stations of study in Ouargla. |
