在印度,由于害虫的危害,高粱产量普遍很低(500～800公斤/公顷)。害虫危害造成的损失将近实际产量的12％。据报道,高粱害虫约有150种,其中具潜在危害的有31种(表)。在印度主要有高粱芒蝇、玉米禾螟、粘虫、高粱摇蚊、穗蝽象、棉铃虫、白虫和高粱穗隐斑螟等。本文总结了当前农业生态系统中各种通用的害虫防治方法,并为印度高粱害虫防治提出了进一步的策略。
In India, sorghum production is generally low (500-800 kg / ha) due to pests. Pest damage caused by the loss of nearly 12% of actual production. About 150 species of sorghum pests have been reported, of which 31 are potentially harmful. Mainly in India, there are sorghum flies, corn borer, armyworm, sorghum mosquito, spike bug, cotton bollworm, white worms and sorghum spike borer and so on. This article summarizes a variety of common pest control methods in agro-ecosystems and proposes further strategies for the control of sorghum pests in India.
