The information presented below arises from these research activities.
From Forest Health News No. 71, February 1998.
We are about halfway through this season's pheromone trapping programme to trap Scolytus multistriatus, the vector of Dutch elm disease. By the end of January 2,162 beetles had been caught, two of which were found to be carrying Ophiostoma novo-ulmi, the fungus that causes Dutch elm disease. One infective beetle was caught at Amey Rd in Remuera, the other at the Domain which as the crow flies is about 1.6 km from Amey Rd. One infected tree has been found, again in Remuera, and the fungus was isolated from both 3 to 4-year-old and current wood. Results are promising although the reservoir of infection at Remuera is causing concern.
