The giant pine scale, Marchalina hellenica Gennadius (Hemiptera: Marchalinidae), is a sap-sucking insect native to South-East Europe that was recently introduced in Australia where it threatens the pine forestry industry. To initiate a classical biological control programme, a literature review and field surveys were carried out in Greece to investigate the natural enemy complex of the scale. While no parasitoids were found, M. hellenica was attacked by several predators, most notably Neoleucopis kartliana Tanasijtshuk (Diptera: Chamaemyiidae). N. kartliana was present at all sites investigated and is presumably specific to Marchalina. This highlights its potential as a biological control agent for M. hellenica. This predatory fly has already been used to control M. hellenica on the Italian island of Ischia. Interestingly, molecular analyses of Greek samples revealed other Chamaemyiidae predatory flies that can be potentially included in the Australian classical biological control programme of M. hellenica.

澳大利亚马氏藻的经典生物防治前景

巨大的松树鳞片，Marchalina hellenica Gennadius（半翅目：Marchalinidae）是一种东南欧原产的树液吸食性昆虫，最近被引入澳大利亚，威胁着松树林业的发展。为了启动经典的生物防治计划，在希腊进行了文献综述和现场调查，以调查该规模的天敌情结。虽然没有发现寄生蜂，M.希腊史是由几个大鳄，最显着的攻击Neoleucopis kartliana Tanasijtshuk（：Chamaemyiidae双翅目）。卡尔特里亚猪笼草存在于所有调查的地点，据推测是特定于马尔凯利娜的。这突出了其作为生物防治剂的潜力。M.希腊史。这种掠夺性的苍蝇已经被用于控制M.希腊史伊斯基亚意大利岛。有趣的是，对希腊样本进行的分子分析揭示了其他Chamaemyiidae掠食性苍蝇，这些苍蝇可能被包括在澳大利亚传统的M. hellenica生物学控制程序中。
