Abstract |
: |
We have limited groups of predatory arthropods (insects - true spiders - spiders harvesting - Scorpions .... etc.) that inhabit the soil in the valley Khulais Western Region of Saudi Arabia, in order to identify and highlight them in three different environmental systems, natural eco-system (desert land), and the system around a variable (vegetable farm), another fixed or permanent (v palm grove and citrus). Has been limited to twelve species of true spiders represented to varying degrees, family Lycosidae is prevailing, and add to that the limited number of insect predators, especially from the rank of beetles land species Carabidae and beetle species Histeridae beetles Alraogh family Staphylinidae, and others include retinal wings, and a needle old.
The study highlighted the existence of a real ant (True ants) family Formicidae, which were collected from the area of sustainable agriculture. Studies have shown in some other arthropods (spiders, harvest, and sun spiders - and scorpions), varying a few degrees. The study showed that there is a diversity evident in terrestrial arthropods that inhabit the soil in different ecosystems. Needed a more accurate and comprehensive studies to determine the true spiders fauna, and then its role in curbing the proliferation of many other insects, especially those occurring damage crops. |
