Abstract

Intercropping is an important practice for controlling crop pests in Ethiopia. However, there is a limited studies on the maize-faba bean intercropping benefits for controlling stemborer (Busseola fusca) pests. This study was carried out at Wukro Agricultural College, Tigray, Ethiopia, to investigate the effects of maize intercrops with two faba bean varieties (Gora and Moti) at three different population levels (25%, 50%, and 75%) of the recommended sole faba bean (250,000 plants ha-1) on infestation, density, and damage of stemborer on maize. The intercrops significantly (p < 0.05) reduced the stemborer infestation, density, and damage on maize over to the sole maize. Maize intercrops with the Gora faba bean variety at a density of 50% lowered the pest damage on maize cobs by 35% relative to the sole maize. The intercrop also reduced the grain yield and economic losses due to the pest by 48% and 53%, respectively, compared to the sole maize. The results recommended that maize intercropped with the Gora faba bean variety at a density of 50% could be used as an alternative farming against stemborer pest in the semiarid farming systems of northern Ethiopia.

在半干旱地区间作玉米-法豆可减少 Busseola fusca (Fuller) 造成的产量和经济损失。
在埃塞俄比亚,间作是控制作物害虫的一种重要方法。然而,关于玉米与蚕豆间作对控制螟虫(Busseola fusca)的益处的研究却很有限。这项研究是在埃塞俄比亚提格雷州的 Wukro 农业学院进行的,目的是调查玉米与两个蚕豆品种(Gora 和 Moti)在三种不同的种群水平(25%、50% 和 75%)(推荐的唯一蚕豆种群水平为 250,000 株/公顷)下间作,对螟虫在玉米上的侵扰、密度和危害的影响。与单种玉米相比,间作玉米明显降低了螟虫的侵扰率、密度和危害程度(p < 0.05)。玉米与 Gora 蚕豆品种间作,密度为 50%,与单种玉米相比,玉米棒上的虫害降低了 35%。与单种玉米相比,间作玉米还将害虫造成的谷物产量和经济损失分别降低了 48% 和 53%。研究结果表明,在埃塞俄比亚北部的半干旱农业系统中,玉米与 Gora 蚕豆品种间作,密度为 50%,可作为防治螟虫的替代耕作方法。
