Abstract

The imp acts of past and potential insect pests and diseases in New Zealand's radiata pine plantations are reviewed. Invariably their impacts have decreased with time or can be easily managed. Despite past biotic impacts. growth rates have increased over the last 100 years. Pitch pine canker (PPC) is perceived as the greatest new threat. PPC's impact in California, Spain, Portugal, South Africa and Chile suggests that in New Zealand it would become a nursery problem. Radiata pine remains the best medium-density softwood for New Zealand although climate change may alter the site limits. While a biotic catastrophe, despite its low probability, remains an important risk, this risk is outweighed by the opportunity costs and risks associated with diversifying into alternative species. A strong biosecurity infrastructure is vital, as is maintaining a broad genetic base from which to breed resistance. Large plantation estates should develop defensive strategies against new biotic invasions.

过去一百年来新西兰辐射松(Pinus radiata D. Don)人工林病虫害影响的教训
综述了新西兰辐射松人工林过去和潜在病虫害的影响。它们的影响总是随着时间的推移而减少,或者可以很容易地控制。尽管过去的生物影响。在过去的100年里,经济增长率一直在上升。沥青松溃疡病(PPC)被认为是最大的新威胁。PPC在加利福尼亚、西班牙、葡萄牙、南非和智利的影响表明,在新西兰,它将成为一个苗圃问题。尽管气候变化可能会改变产地范围,但辐射松仍然是新西兰最好的中密度软木。尽管发生生物灾难的可能性很低,但它仍然是一个重要的风险,这种风险被机会成本和向其他物种多样化所带来的风险所抵消。强大的生物安全基础设施至关重要,维持广泛的遗传基础以培育耐药性也至关重要。大型种植园应该制定防御新生物入侵的策略。
