|Title:||APERÇU SUR LA FAUNE ARTHROPODOLOGIQUE DES PALMERAIES D’EL-KANTARA|
|Abstract:||During our study of the arthropodologic fauna of the area of Biskra we have chose two test centers in the zone of El- Kantara. Two types of palm plantations exist, modern and traditional. Our inventory reveals the presence of 48 species invertebrates, same ones observed in each site but with different manpower, always let us announce that the traditional palm plantation is most dominant with a total rate of 67,87%. The class of the insects is populated by 46 species, that is to say 95,84% of totality. It is followed by that of crustacean and that of Arachnida by only one species and a percentage of 2,08% each one. According to the systematic order the orthoptera are classified in first position with a rate of 18,75 %, followed by the Coleoptera 16,67%, the Lepidoptera and the hymenoptera with 14,58 % each one. According to the food mode we noted five groups whose Phytophagous ones are represented with a rate of 56,25 %, followed by the predatory ones with 20,83 %, the Saprophagous with 18,78 % and finally the parasites and the Polyphagous ones with a rate of 2,08 % each one.|
