Abstract

Abstract The objective of this work was to evaluate the potential of cover plants in reducing the population of the two-spotted spider mite, Te t r a n y c h u s urticae, in soybean. Seven host plants – cotton (Gossypium hirsutum), Urochloa ruziziensis, crotalaria (Crotalaria juncea), corn (Zea mays), radish (Raphanus sativus), soybean (Glycine max), and sorghum (Sorghum bicolor) – were evaluated for their effect on T. urticae biological parameters (oviposition, development stages, and survival) and preference for volatile odors (using a Y-tube olfactometer). Tetranychus urticae preferred cotton and showed a higher population growth rate on this host plant. The survival and oviposition of T. urticae was prolonged in radish and crotalaria plants, whereas juveniles did not complete their immature development on U. ruziziensis leaves. No preference was observed between the volatile odors of U. ruziziensis, radish, and crotalaria. Urochloa ruziziensis can reduce T. urticae populations in soybean plants.

覆盖有潜力减少大豆双斑蜘蛛螨种群的植物

摘要本研究旨在评价覆盖植物对大豆双斑蜘蛛螨种群的抑制作用。研究了棉花(Gossypium hirsutum)、ruziziensis、crotalaria juncea (crotalaria juncea)、玉米(Zea mays)、萝卜(Raphanus sativus)、大豆(Glycine max)和高粱(sorghum bicolor)等7种寄主植物对荨麻粉虱生物学参数(产卵、发育阶段和存活)和对挥发性气味的偏好(使用y管嗅觉仪)的影响。荨麻叶螨偏爱棉花，在棉花上表现出较高的种群增长率。在萝卜和甘蓝植株上，荨麻疹夜蛾的存活和产卵时间较长，而幼虫在紫荆叶片上发育不完全。红萝卜挥发性气味与红萝卜挥发性气味没有明显的差异。褐藻可减少大豆植株上的荨麻疹菌种群。
