近日,阿根廷图库曼省拉克查农田中发现棉铃虫(Helicoverpa armigera)毛虫,由于这种虫害具有毁灭性的破坏力,阿根廷农业受到了新的威胁。棉铃虫具有很强的迁移性,虫灾蔓延迅速,并可对超过100种作物造成影响。棉铃虫在阿根廷鹰嘴豆作物田的陷阱装置中被发现,而在巴西,已经存在于棉花、大豆和玉米地中。由于棉铃虫对幼株和谷物穗粒都能造成破坏,已使巴西作物蒙受巨大损失。 Recently, Helicoverpa armigera caterpillars were found in the farmland of Rakha, in Tocumen province, Argentina. Due to the destructive destructive power of this pest, Argentine agriculture is under new threat. Helicoverpa armigera is highly migratory and has a rapid spread of insect pest and can affect over 100 crops. The cotton bollworm was found in the trap device of the chickpea crop field in Argentina, and in Brazil already exists in cotton, soybeans and corn fields. The damage to Brazil’s crops has been caused by the damage that cotton bollworms can cause to both young and cereal grains.
