FIRST URBAN BREEDING OF TRUMPETER FINCH BUCANETES GITHAGINEUS IN THE SAHARA DESERT IN ALGERIA | | Author : Choayb Bounab, El-Yamine Guergueb, Soumia Haddad, Amria Abed, Oumyma Zouatine, Radhia Biad, Yassine Nouidjem | | Abstract | Full Text | Abstract :The subspecies Roselin githagine Bucanetesgithagineus zedlitzi is found in arid and semi-arid
environments of North Africa. In this study, we tracked this species in an urban landscape within a
Saharan region to evaluate the impact of the urban gradient on its distribution, to characterize the
reproductive parameters in an urban environment, and to report the first case of nesting of this species,
in an urban setting. Over a seven-month study period, we regularly visited 90 listening points
distributed in three habitats (urban, suburban, and rural). Statistical analysis of the data, using one-
way analysis of variance (ANOVA) for recent counts in the three habitats, showed a significant result
with a p-value of 0.04, indicating a significant difference between the different habitats. Furthermore,
the study of the reproductive parameters of this species revealed that the population had a late laying
date and relatively larger egg dimensions compared to other populations studied in Algeria. |
| BIOLOGICAL STRUGGLE AGAINST TWO HURMFUL INSECTS – BLATTELLA GERMANICA (BLATTELLIDAE) AND CULISETA LONGIAREOLATA (CULICIDAE) – USING EUPHORBIA BUPLEUROIDES (EUPHORBIACEAE) | | Author : Bounadji Siham, Benhissen Saliha, Belkhiri Nora, Asloum Abdelmadjib Yagoub, Habbachi Wafa, Rebbas Khellaf | | Abstract | Full Text | Abstract :This study is topical and is of particular importance with the emergence and spread of vector-
borne diseases in urban areas around the world, and in Algeria in particular. In this work we carried
out a toxicological test on the larvae of two species namely Culiseta longiareolata and Blattella
germanica which are considered harmful and can be carriers of many pathogens, with the use of the
aqueous extract of the plant Euphorbia bupleuroides for a certain time, the results of toxicity give a
toxic effect on the larvae determined at different lethal concentrations and sublethal (LC 50 % and LC
90 %). |
