Abstract
Giant reed, Arundo donax (L.), is known for its potential as a bioenergy crop. To evaluate the effect of the aphid Melanaphis donacis (Passerini) on plants growing in the Metropolitan Region of Chile, three treatments with six plots each were compared: imidacloprid, the agricultural detergent TS2035, and an untreated control. Aphid density levels in the untreated control plants averaged 136.27 aphids leaf-1 along the growing season, while TS2035 and imidacloprid averaged 8.26 and 0.98 aphids leaf1, respectively. The greatest yield of A. donax (95.1 t dry matter (DM) ha-1) was obtained with the TS2035 detergent, followed by imidacloprid and the untreated control, with values of 88.8 and 84.1 t DM ha-1, respectively. However, there were no significant differences (p ≤ 0.05) in DM yields of A. donax between treatments. Thus, control of M. donacis with insecticides would be unnecessary in bioenergy crops of A. donax in this region.
巨型芦苇以其作为生物能源作物的潜力而闻名。为了评估黑腹蚜(Passerini)对智利大都会区植物生长的影响,对三种处理方法(每种处理6块地)进行了比较:吡虫啉、农业洗涤剂TS2035和未经处理的对照。未处理对照植物的蚜虫密度水平在生长季节平均为136.27个蚜虫叶1,而TS2035和吡虫啉的平均蚜虫叶1分别为8.26和0.98。使用TS2035洗涤剂获得了最大的A.donax产量(95.1 t干物质(DM)ha-1),其次是吡虫啉和未处理的对照,其值分别为88.8和84.1 t DM ha-1。然而,不同处理之间的A.donax的DM产量没有显著差异(p≤0.05)。因此,在该地区的A.donax生物能源作物中,用杀虫剂控制M.donacis是不必要的。
