    Strategy efficiency to control Meriones shawi (Duvernoy, 1842) (Rodentia Gerbillinae) infestation in Tiaret region during the period (2015–2020), Algeria

    ABSTRACT
    Tiaret is confronted with arvicultural rodents invading considerable areas, despite the control programs adopted. The analysis of the abundance of Meriones shawi (Duvernoy, 1842) (Rodentia Muridae Gerbillinae), despite the application of the rodenticide during the five agricultural campaigns (2015–2020), revealed a growing and considerable infestation, clearly heterogeneous in the spatial distribution across the 14 dairas, with peaks of infestation recorded in the regions of Sougueur and Mahdia. Our analysis focuses on two main aspects, namely the diet of the rodent and the composition of the landscape in which it thrives. We were able to conclude that the populations are more abundant in the dairas of Sougueur and Mahdia having cereal vocation mainly cultivated in barley, which offer to the M. shawi food, security against predators and especially more mobility. On the other hand, the heterogeneous reliefs with a cover plant variety constitute unfavorable environments for the proliferation of rodents, as in the case of Mghila. Therefore, in order to have a more efficientcontrol strategy, the nature of the area should be taken into consideration before applying the rodenticide.

    Entomofaunal diversity of Diptera in a semi arid region in the west of Algeria (Tiaret)
    https://doi.org/10.31396/Biodiv.Jour.2021.12.3.567.572

    ABSTRACT
    The contribution to the study of the biodiversity of Diptera associated with the cultivated olive tree took place over a year from December 2018 to November 2019, in two stations located in the west of Algeria. The aim of this present work is to learn about the biodiversity of Diptera associated with the olive tree cultivated in the Tiaret region. Sampling frequency was on the order of one outing per month using the yellow plates and barber jars to collect the specimens. We identified 1124 individuals or 46 species belonging to 29 families. The Sciaridae family is the most representative in Ain Guesma station with a relative abundance AR% of 23%. While in the station of Oued lili the Chirinominidae family is the most captured, at 18.52%. The two stations present a great diversity of species (H ’= 3.58 Ain Guesma, H’ = 3.65 in Oued Lili). The equity of the species identified in this study is greater than or equal to 0.76.

    Impact of Nematode Heterodera avenae Wollenwebwer, 1924 (Heteroderidae) attack on cereal yields in the region of Tiaret (Algeria)
    https://doi.org/10.31396/Biodiv.Jour.2020.11.4.1031.1036

    ABSTRACT
    The cyst nematode Heterodera avenae Wollenweber, 1924 (Heteroderidae) is an obligate endoparasite of grasses. It is the most studied and most damaging nematode known for more than a century. The study of the distribution of the H. avenae cyst nematode was carried out on some plots of cereal-oriented municipalities in the Tiaret region to assess the infestation levels of the plots in order to study the impact of the nematode infestation on cereal yields. Spearman’s test was used, which allowed us to study the correlation between the degree of infestation and cereal yields, particularly wheat, barley and oats. The plots of the communes surveyed are all infested by H. avenae with different levels of infestation except the plots of the town of Sebaine and Mahdia where the infestation is practically non-existent (0 cysts/100 g of soil). The correlation is negative between the degree of infestation and the yield (r = -0.06), the yields of hard wheat are low when the degree of infestation is high. Soft wheat and barley yields are negatively correlated with respectively, r = - 0.26 and r = -0.27, therefore, heavy infestations of the nematode lead to a decrease in yield. Unlike other cereal species, the correlation is positive with the degree of infestation (r = 0.18), so the infestation of the nematode did not greatly influence oat yields. Oats are a tolerant species for nematode attack in relation to wheat and barley that have recorded decreases in yields. Unlike the three previous crop types, oats stand out for their tolerance to this parasite.

    Inventory of scorpion fauna (Arachnida Scorpiones) in Tiaret region (Algeria)

    ABSTRACT
    The present work was carried out in the region of Tiaret to study the diversity of scorpions in western Algeria. In this locality, three stations were chosen: the first one is a rocky area, the second one is represented by a scrub and the third is an anthropized zone. The scorpions sampling was done, during the year 2017, randomly and it was carried out by searching the scorpions in their hiding places, where a total of 200 individuals were sampled. The specimens morphometry, based on the measurement of 8 parameters, made it possible to diagnose two families: Buthidae represented by two species Buthus occitanus (Amoreux, 1789) (88.5%) and Buthacus arenicola (Simon, 1885) (7%) and Scorpionidae represented by Scorpio maurus Linnaeus, 1758 (4.5%). Among the measures that make the difference between these species, we mention the width of the chela, which is of the order of 3.03 ± 0.67 for Buthus occitanus and 2.27 ± 0.49 mm for Buthacus arenicola, while Scorpio maurus has larger chela.
