在印度为害甘蔗的螟虫约十几种,二点螟在甘蔗苗期为害不像其他蔗螟有地区局限性。它在所有植蔗地区均有发生。这种蔗螟在甘蔗幼苗内蛀食,在顶端蔗节近心叶处环食致断造成枯心及死蘖。对苗期的甘蔗极不利于其正常生长。蔗株受害后刺激无效分蘖增加。蔗茎受害后产量和糖份都有不同程度的损失。完善的防治措施仍需不断研究探索。与二点螟生物学特性的有关问题幼虫有隐蔽的习性,侵害期绝大部分时间躲匿在蔗蘖内食害,幼虫孵化后即能为害蛀成
About a dozen of stem borers that harm sugarcane in India, and the two-point borer are not as localized at the sugarcane seedling stage as other sugarcane borers. It occurs in all sugar cane areas. This sugarcane borer eats in sugarcane seedlings and causes ringing and dead tillers at the top of the caryatids near the leaf center. The seedling of sugar cane is very detrimental to its normal growth. Irrigated cane tillers increased after injury. Cane stem damage yield and sugar have varying degrees of loss. Perfect prevention and control measures still need continuous research and exploration. And the borer borer biological characteristics of the problem larvae have hidden habits, most of the damage during the hide hiding in the cane tillering, the larvae can hatch after incubation into
