摘要

覆盆子(蔷薇科)被认为是摩洛哥西北部最重要的作物之一。然而,该产业受到苏氏果蝇的严重影响,生产和出口都受到损害。此外,人们对摩洛哥条件下的生态生态学和铃木果蝇种群动态仍然知之甚少。在拉腊什地区,我们用 4 个诱捕器监测了小铃虫成虫的种群动态,诱饵为混有酵母的成熟香蕉泥,并报告了 2022 年、2023 年和 2024 年春季树莓栽培品种 Rubus idaeus var.我们的研究结果表明,在 2022 年 4 月底、2023 年 3 月中旬和 2024 年 4 月中旬,每周每个诱捕器最多分别捕获 14、20 和 28 个小铃虫成虫。此外,每年观察到三次成蝇高峰,而根据累积度日预测总共有六代。在 2022 年、2023 年和 2024 年,诱捕到的雄性虫蝇性别比分别为 1:0.32、1:0.38 和 1:0.42。树莓果实侵染率在 2022 年 5 月初、2023 年 4 月中旬和 2024 年 4 月底分别达到 76%、75% 和 64%的最高值。在气候变化情况下,了解这种昆虫的生态生态学及其种群动态对于在摩洛哥制定 IPM 控制策略至关重要,目前正在开展进一步研究,以建立基于度日的生物和合理化学方法。

Drosophila suzukii (Diptera: Drosophilidae) Population Dynamics and Infestation in a Raspberry Orchard of Loukkos Area, Morocco.

Raspberries (Rosales: Rosaceae) are considered to be one of most important crops in northwestern Morocco. However, this sector is seriously affected by the attack of Drosophila suzukii, which impairs the production and the export. Furthermore, the eco-ethology and population dynamics of D. suzukii under Moroccan conditions are still poorly understood. In Larache region, we monitored the population dynamics of D. suzukii adults using 4 traps baited with mashed ripe banana mixed with yeast, and reported the infestation levels during spring of 2022, 2023, and 2024 on raspberry cultivar Rubus idaeus var. Yazmin. Our results indicate that a maximum of 14, 20, and 28 D. suzukii adults per trap were caught weekly at the end of April 2022, in the middle of March 2023, and in the middle of April 2024, respectively. Furthermore, three peaks of D. suzukii adult flies were observed each year, whereas a total of six generations were predicted according to the accumulated degree-days. The male sex ratio of trapped D. suzukii was 1:0.32, 1:0.38, and 1:0.42 in 2022, 2023, and 2024, respectively. Raspberry fruit infestation reached a maximum of 76%, 75%, and 64% at the beginning of May 2022, middle of April 2023, and end of April 2024, respectively. Under the climate change scenario, knowledge of the eco-ethology of this insect and its population dynamics is essential for developing an IPM control strategy in Morocco, and further studies are ongoing to establish a biological and reasoned chemical approach based on degree-days.
