Abstract

Fruit flies (Diptera: Tephritidae) are cosmopolitan, species-rich, and yet poorly studied in Algeria, particularly in the agro area of Djelfa. We sampled fruit flies in orchard containing three types of trees apricot, fig and grapes at each site, using the yellow traps. Results show that the orchard differed significantly in species richness, abundance, diversity and evenness. A total of 956 individuals distributed by nine species of Diptera, including four species of fruit flies are collected. The results revealed that most abundant species are Drosophila melanogaster at the apricot fruit site (RA%=28.32%), Zaprionus indianus at fig fruit site (RA%=34.74 %) and Tephritis praecox at the grapes fruit site with (RA%= 51.61 %). The orchard selected a greater number of species and individuals, and higher diversity indices H′=2.40 bits; 2.32 bits and 2.02 bits. Statistically, the result of stepwise multiple regressions revealed a very strong correlation between the number of fruit fly species and the temperatures with (r=93.1%) and (Sig .000**). Thus, fruit flies appear to have rather arrow with the host plant requirements and their phenology was correlated with environmental differences. Our study highlighted for; the first time; the presence of Trupanea amoena in Algeria. This important and substantial preliminary work on this new species in Algeria provides a solid basis for future research and extension of the study in particular for monitoring and control of this dreaded agricultural pest.

Abstract

As an alternative to chemical treatments, traps are one of the most environmentally friendly ways to control pests in agricul-tural systems. The efficacy of traps can be maximized by taking adventage of the fact that arthropods, and especially pests, have preferences for certain colors and stimuli. From January to De-cember 2022, in the locality of Corso, situated in Boumerdes Province, Northern Algeria. The experimental site consisted of a three-year-old table grape plantation. A descriptive observa-tional method was employed to assess the performance of four different trap types: pitfall traps, food-based traps, and two col-or-based traps (yellow and blue). The experiment followed a completely randomized design with five replications to ensure reliable and accurate results. Yellow traps proved to be the most successful throughout the research., capturing a total of 1,925 arthropod individuals. In contrast, food-based traps were the least effective, with only 14 individuals captured. The traps re-vealed a richness of 106 species spanning 54 families, 11 orders, and 3 classes, highlighting the diverse arthropod community present in the vineyard ecosystem. The most frequently captured species was Jacobiasca lybica, which accounted for 81.6% of the total pests trapped. The timing of trap installation was also a crit-ical factor, with the morning period yielding the highest capture rates. These findings underscore the importance of using color-specific traps and strategic timing to enhance pest management in vineyards.

Abstract

The Erotylidae family remains poorly documented in North Africa, with very limited published data available on its distribution and ecological preferences. This study provides the first confirmed record of Triplax melanocephala (Latreille, 1804) within Algerian cork oak (Quercus suber) forests, significantly expanding the known range of this species in the region. A total of 71 specimens were documented, collected primarily through soil-surface interception traps deployed across multiple sites. Among these, 25 individuals were captured between 2015 and 2016 in different sections of the surveyed oak groves. Field observations revealed that T. melanocephala exhibits a strong association with decaying cork oak wood, particularly in trees heavily colonized by mature tinder fungi (Fomes spp.). Further investigation through careful dissection of these fungal growths uncovered an additional 30 specimens, reinforcing the species' reliance on this microhabitat. The beetles were most frequently found in moist, shaded areas of decomposing wood, suggesting that microclimatic conditions may play a key role in their distribution. The study sites included Oued Agouf, where 2 specimens were collected in 2015 and 4 in 2016; Ain Fegoum, with 6 specimens in 2015 and 8 in 2016; and El Maktoua, where 4 specimens were recorded in 2015 and 6 in 2016. These findings indicate a consistent presence of T. melanocephala across multiple locations, though population densities varied between sites. This discovery not only fills a gap in the understanding of Erotylidae in North Africa but also highlights the ecological importance of old-growth cork oak forests and their associated fungal communities in supporting specialized beetle fauna.
