摘要
随着锥栗林面积的不断扩大,锥栗虫害发生日趋严重,若不采取有效措施防治,将影响锥栗产业的可持续发展。为了解锦屏县锥栗虫害发生情况,本研究对锦屏县锥栗主要害虫的种类及发生危害情况进行了调查。结果表明,锦屏县锥栗主要害虫有30种,涉及6目21科。其中,危害程度达到轻度的害虫有18种,危害程度达到中度的害虫有7种,危害程度达到重度的害虫有5种。本文初步明确了主要害虫和次要害虫,并介绍了栗卷象、栗瘿蜂、栗大蚜、栗叶瘤丛螟、黑额光叶甲5种重度危害害虫的生物学特性及危害特点。
With the continuous expansion of Castanea henryi forest area,the occurrence of pests is becoming increasingly serious.If effective measures are not taken to prevent and control it,it will affect the sustainable development of the Castanea henryi industry.In order to understand the occurrence of Castanea henryi pests in Jinping County,this study investigated the species and occurrence of the main pests of Castanea henryi.The results showed that there were 30 main pests of Castanea henryi in Jinping County,involving 6 orders and 21 families.Among them,there were 18 species with mild damage,7 species with moderate damage,and 5 species with severe damage.This paper preliminarily clarified the main and secondary pests,and introduced the biological characteristics and damage characteristics of five severely harmful pests,including Paracycnotra cheluslongiceps,Dryocosmus kuriphilus,Lachnus tropicalis,Orthaga achatina and Smaragdina nigrifrons.
