Changes in Major Insect Pests of Pine Forests in Korea Over the Last 50 Years
Here, we review the history of the occurrence patterns and causes of outbreaks and declines of pests in Korean pine forests over the last 50 years. During this period, the major pests of pine forests in Korea have shifted from pine caterpillar (Dendrolimus spectabilis Butler) to the pine needle gall midge (PNGM, Thecodiplosis japonensis (Uchida and Inouye)) and finally to pine wilt disease (PWD) caused by the pine wood nematode (Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle). A new management strategy for controlling forest pests is required to mitigate the decline of pine forests in Korea.

Editorial: Forest health under climate change: effects on tree resilience, and pest and pathogen dynamics
Climate change is having important effects on forest dynamics, which can be both positive and negative for natural and managed ecosystems. To date, most empirical and synthesis research has focused on climate change implications for tree species distributions and productivity, while the potential impacts on forest pests and pathogens and the effects on tree population health have been comparatively neglected. These present some of the greatest threats to global forest health under climate change. Climate change is altering the distributions and population structures of forest pests and pathogens, the way they interact with trees, and their evolutionary capacity, while also affecting the capacity of forest systems to resist and tolerate attacks.

Endophytes vs tree pathogens and pests: can they be used as biological control agents to improve tree health?
Like all other plants, trees are vulnerable to attack by a multitude of pests and pathogens. Current control measures for many of these diseases are limited and relatively ineffective. The use of biological control, as a more environmentally friendly alternative, is becoming increasingly popular in plant protection. The development and exploitation of endophytes as biocontrol agents will have to overcome numerous challenges. The optimization and improvement of strategies employed in endophyte research can contribute towards discovering effective and competent biocontrol agents. This review focusses on recent research addressing the biocontrol of plant diseases and pests using endophytic fungi and bacteria, alongside the challenges and limitations encountered and how these can be overcome.

Calonectria pentaseptata causes severe leaf disease on cultivated Eucalyptus in Leizhou Peninsula of southern China (Abstract only)
Eucalyptus (Myrtaceae, Myrtales) trees are widely cultivated for commercial purposes worldwide. Calonectria leaf blight is one of the most prominent diseases associated with Eucalyptus trees grown in plantations in Asia and South America. Recently, symptoms of leaf blight, shoot blight, tree death and seedling rot caused by Calonectria species have been observed in commercial Eucalyptus plantations and nurseries in Leizhou Peninsula, which presents one of the most densely Eucalyptus-planted areas in southern China. It is urgent to initiate a selection program to develop Eucalyptus planting stocks with high levels of resistance to Calonectria leaf blight in China in the long term.

Phylogenetic characterization of bacterial endophytes from four Pinus species and their nematicidal activity against the pine wood nematode
Recently, bacterial endophytes (BEs) have gained importance in the agricultural sector for their use as biocontrol agents to manage plant pathogens. Outbreak of the pine wilt disease (PWD) in Korea has led researchers to test the feasibility of BEs in controlling the pine wood nematode (PWN) Bursaphelenchus xylophilus. In this study, we have reported the diversity and biocontrol activity of BEs against the PWN. Altogether, our study furnishes a basic comprehension of bacterial communities found in the Pinus species and highlights the potential of BEs as biocontrol agents to combat PWD.
