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.

Understanding how climate and host plant characteristics drive pest dynamics is essential for sustainable vineyard management. This study investigated the seasonal population dynamics of Frankliniella occidentalis and Jacobiasca lybica across four grapevine cultivars (Dabouki, Muscat, Red Globe, Victoria) in Boumerdès, northern Algeria, during the 2022 growing season. Both species showed distinct seasonal patterns, with F. occidentalis peaking in mid-summer and J. lybica reaching maximum abundance in late August. Jacobiasca lybica was strongly correlated with temperature, whereas F. occidentalis was negatively influenced by rainfall. The generalised linear models highlighted the significant effects of climatic variables on pest abundance. Among the grape cultivars, Dabouki exhibited higher infestation levels by J. lybica compared with the other cultivars, while no significant cultivar-related differences were observed for F. occidentalis. Redundancy analysis identified temperature as the main environmental factor shaping pest population dynamics. These results highlight the combined influence of climate and cultivar susceptibility on pest dynamics and support locally adapted integrated pest management in Mediterranean viticulture.
