It is unfortunate that this seed-destroying moth parasitizes both A. macrophylla and A. obtusa which are probably the potentially most important species of Agathis for foresters (Chapter 5). It is vitally important that it is not spread to other places where plantations especially might become infected. It was described in sect. 6·2 that storage of Agathis seed by
desiccation followed by cold storage is likely to be the most practicable technique. Agathiphaga is killed by sub-zero temperatures and the developing imago is crippled by low temperatures.
