摘　　要：油松球果小卷蛾是近年来危害黄平县马尾松种子园的主要害虫之一,造成了难以估量的经济损失。通过对该虫生物学特性的研究表明,该虫在贵州省黄平县1年发生一代,以蛹在杂草及松土层内越冬,成虫期4月中旬至6月中旬,卵期5月上旬至6月下旬,幼虫期5月中旬至7月中旬,蛹期7月中旬至次年5月中旬。提出了初步的防治建议和措施。Gravitarmata margarotana is one of the major pests attacking the seed orchard of Pinus massoniana in Huangping County,having resulted in inestimable economical loss.Study on the Bionomics of Gravitarmata margarotana showed that this pest has one generation in a year.It overwinters as pupa in the weed clumps or the loose soil layers;the adults emerged from mid April to mid June,and oviposited from early May to late June;the larvae emerged from mid May to mid July and the pupa emerged from mid July to late May of the next year.At the end of this paper,some preliminary measures to control this pest were proposed.
