Biodiversity of the Blattopteran Fauna in the Chelia Cedar Forest (the Aures - Eastern Algeria)

The cedar forests in Algeria represent a model of forests very rich in entomological fauna and especially dictyopterans, notably blattopterans. In the cedar forest of Chelia in the Aurès Mountains, we chose three different sites according to altitude (2020 m, 1920 m, 1820 m) in order to collect existing cockroaches using the sight-hunting method (twice a month). The inventory allowed us to capture more than 1220 cockroaches and we were able to identify three genus (Dziriblatta, Phyllodromica ,Loboptera) and seven species: Dziriblatta stenoptera, Dziriblatta nigrivintris, Phyllodromica zebra, Pyllodromica trivittata, Phyllodromica sp, Loboptera angulata, Loboptera alluaudi, of which Dziriblatta nigrivintris is the most abundant species with a rate of 52.05 % .The results show that the distribution of these species in the diffrent sites in Chelia cedar is controlled by a several natural factors such as (temperature, altitude …etc)

Inventory and Distribution of Mosquitoes (Diptera, Culicidae) in the Aures Region (Batna, Algeria)

Mosquitoes are the most terrifying both for their abundance and for the diseases they transmit. They are vectors of malaria, lymphatic filariasis and arbovirus such as yellow fever, dengue, viral encephalitis and African horse sickness. These characteristics give this fauna prominent importance and health interest. To identify the most widespread mosquito species, we conducted for the first time an inventory in the Aures region more particularly the wilaya of Batna (East of Algeria) from May 2017 to January 2020, we studied their diversity, abundance and distribution. The sampling is done by monthly surveys of the various localities chosen, using the dipping method to collect the larvae. In the various sites prospected, we were able to collect a total of 8275 mosquito individuals presented by nine species belonging to four different genera: Culiseta, Culex, Aedes and Anopheles of which the genus Culiseta is the best represented, particularly with the species Culiseta longiareolata (52.07%). It appears from what we have obtained that the Batna region reveals a significant diversity of mosquitoes. This study aimed to inventory the Culicidian species more broadly by surveys in several localities of Batna region at the level of different environments. This will allow us to know the faunistic composition of the region, to collect and record information on the vectors, their habitats and the conditions that favors their multiplication within a given area

Toxicity of Three Species of The Solanaceae Family Growing in Algeria Against Culiseta Longiareolata Mosquitos 4th Stage Larvae

Mosquitoes have always been considered a source of harm to humans and animals mainly because they can be vectors of disease. This work represents a study on the effect of aqueous extract of three plants (Hyoscyamus albus, Solanum elaeagnifolium, Solanum nigrum) of the Solanaceae family on the mortality of 4th stage larvae of Culiseta longiareolata larvae. Extract of the high impact is of S. nigrum followed by H. albus and S. elaeagnifolium, respectivley of C. longiareolata larvae
