Abstract
SUMMARY The incorporation of native kauri pine Agathis spp. into the plantation development programme of Queensland has been hampered by restricted sites, shortage of seed and insect pests. During 1959 extensive defoliation of kauri pine in the Imbil Forestry Sub-District was caused by the kauri coccid Conifericoccus agathidis Brimb. Secondary insect and fungal disease attacks contributed to deaths of trees after three years of consistently heavy coccid damage. This paper records some aspects of the insect outbreaks.
