dc.description.abstract | The inventory of the arthropodological fauna in the two agro-systems studied, i.e. the palm grove and the greenhouse, allowed us to note that the family Coccinellidae occupies the first place among the order Coleoptera with an AR% = 35,62% in the month of April in the palm grove and 40.76% in the greenhouse. The palm grove is the richest in ladybird species with 07 species reported (248 individuals) with a predominance of Pharoscymnus ovoideus (13,63%) and Pharoscymnus numidicus (13,46%). At the level of the Greenhouse, only 04 species (325 individuals) are recorded, namely Coccinella algerica (36,30%), Coccinella novomnotata (42,15%), Hippodamiatredecim punctata (15,38%) and Coccinella undecimpunctata (6,15%). The study of the predatory capacity of the ladybirds inventoried showed that Pharoscymnus ovoideus is more voracious (19,33 individuals of white cochineal/24h) compared to Pharoscymnusnumidicus. The aphidiphagous ladybirds also show different predatory abilities. Coccinellanovemnotata is the most voracious with an average of 61,67 individuals/24h. The species Coccinella algerica devours the least amount of aphids with an average of 49,67 individuals/24h | en_US |
