    Acaricidal Activity of Aqueous Extracts against the mite of date palm Oligonychus afrasiaticus Meg (Acari: Tetranychidae)
    (Journal of Medicinal Plants Studies 2015; 3(6): 113-117, 2015) Lakhdari, Wassima; Dehliz, A; Acheuk, F; Soud, A; Hammi, H; Mlik, R; DOUMANDJI-MITICHE, Bahia
    The use of chemical products to fight against insects raises several concerns related to the environment, human health, non-target species and development of resistant pest populations. The use of bio-pesticides may reduce the risks of pests and safeguard biodiversity. This experiment was conducted with the objective to study the effect of aqueous plant extracts from the southeast region of Algeria (Zygophyllum album L, Cotula cinerea Del and Limoniatrum guyonianum Del) on the mortality of the date palm mite (Oligonychus afrasiaticus). The trial was conducted at the Laboratory of Plant Protection of INRAA. The five doses (1%, 2%, 3%, 4%, and 5%) were tested on adults of phytophagous. The results show that the extracts of plants and C. cinerae and L. guyonianum do not show an effect on the pest. Unlike, Z. album showed a very significant effect on the mite by a mortality rate of 76%.

    Host Plant Determination of Brachytrupes megacephalus Lefebvre, 1827 (Orthoptera, Grillinae) Using Faeces Analysis in the Region of Oued Righ (Algerian Sahara)
    (American-Eurasian J. Agric. & Environ. Sci., 15 (2): 271-277, 2015, 2015) Lakhdari, Wassima; DOUMANDJI-MITICHE, Bahia; Dahliz, A; DOUMANDJI, Salaheddine; Bendifellah, L; Bouchikh, Y; Hammi, H; Soud, A; Mlik
    In the southeast of the algerian Sahara (Touggourt), the host plant determination of Brachytrupes megacephalus was studied by faeces analysis (microscopic observations). The experimentation was conducted in mid August until the end of September 2014. The main results of faeces analysis showed that the plants consumed by B. megacephalus belong to 8 families: Arecaceae (Phoenix dactylifera), Apocynaceae (Nerium oleander), Asteraceae (Chrysanthemum), Myoporaceae (Myoporum sandwicense), Plumbaginaceae (Armeria maritima), Rosaceae (Prunus armeniaca), Solanaceae (Solanum lycopersicum) and Triochylaceae (Cherry fantasia and White Kristina). Phoenix dactylifera is the most preferred host species by the adults of Brachytrupes megacephalus, with a consumption rate 85,87%.
