摘要

1998年,在希腊对颗粒状线虫(Nemolecanium graniformis,Wunn)(同翅目:蚧科)在头足类冷杉(Abies cephalonica)中的酚类和天敌进行了研究 – 1999年。这种产卵物种在希腊中部(阿提卡)每年发育一代,并作为2龄若虫越冬。幼龄雌性在7月底出现,一龄若虫在8月中旬出现。到10月中旬,该规模的整个种群被记录为2龄若虫。寄生蜂Coccophagus lycimnia(Walker)、Coccophages Westwood sp.、Aphycoides Mercet sp.和捕食者Exochomus quadripustulatus L.(鞘翅目:Coccinellidae)被观察为该规模的天敌。粒形猪笼草的平均产卵量为188.4枚。

The scale Nemolecanium graniformis (Wunn) (Homoptera: Coccidae) in Greece

The phenology and natural enemies of Nemolecanium graniformis (Wunn) (Homoptera: Coccidae) in infesting Abies cephalonica, were studied in Greece during 1998 – 1999. This oviparous species develops one generation per year in Central Greece (Attica) and overwinters as 2nd instar nymph. Young adult females appear by the end of July, and the first instar nymphs by the middle of August. By the middle of October, the whole population of the scale is recorded as 2nd instar nymphs. The parasitoids Coccophagus lycimnia (Walker), Coccophagus Westwood sp., Aphycoides Mercet sp. and the predator Exochomus quadripustulatus L. (Coleoptera: Coccinellidae), were observed as natural enemies of the scale. The average fecundity of N. graniformis was 188.4 eggs.
