在1981～82年的收获季节里,印度喀拉拉邦艾杜基地区许多小豆蔻种植园的产量异常低。这主要是不利的气候条件及病害的传播造成的。但在小豆蔻开花季节花序蛀螟的为害,也是低产的一个重要原因,在某些地区这种虫害甚至已造成小豆蔻生产的严重损失。通常,蛀螟为害小豆蔻的嫩枝、蒴果和花序。但该年对花序的危害却是灾难性的。大量花序从中部枯萎,花序上可见幼

This is mainly caused by unfavorable weather conditions and the spread of diseases.

Common borer moths damage cardamom’s shoots, capsules, and inflorescences. But the damage to the inflorescence that year was disastrous. A large number of inflorescence withered from the middle, inflorescence visible young
