摘要
1984～1988年在辽宁省兴城油松种子园对直接危害油松球果的害虫进行了调查,发现有松果梢斑螟、微红梢斑螟、松实小卷蛾及金绿宽盾蝽,对这4种害虫的生活史、发生历期和生物学特性作了研究。
Four species of cone insects i.e.,Diotyctria pryeri,D.rubella,Petrova cristata and Poecilocoris lewisi were discovered in the seed orchard during 1984~1988.The time of occurence,damage,and the biology of the insects were closely observed.D.pryeri and P.cristata damaged the growing conlets,resulting in the complete loss of the seeds in them,The percentage of the damaged cones adjacent to the conlets attacked by the insects the year before,was higher than that of the average in the seed orchard.
