摘要

Mortality tests were conducted in a large-scale applied test with methyl iodide (MI) to confirm complete mortality and CT products for the pine wood nematode, Bursaphelenchus xylophilus (STEINER and BUHRER) NICKLEI Red pine lumber (15 cm thick x 15 cmwide x 30 cm long in size) infected with the pine wood nematode were fumigated at different doses of MI at different temperatures for 24 hours with 25 and 50% loading. No surviving nematode was observed on samples fumigated at 60 g/m~3 at 10°C, 40g/m~3at 15 and 20°C and at 30g/m~3 at 25°C, respectively. The CT product for complete mortality was estimated to be 450 mg centre dot h/l at 10°C, 400 mg centre dot h/l at 15°C, 350 mg centre dot h/l at 20°C and 300 mg centre dot h/l at 25°C, respectively. Applied doses of MI were required for warehouse and tarpaulin fumigation, that is, at each of 84g/m~3 at 10°C, 60g/m~3 at 15°C, 48 g/rri at 20°Cand 36g/m~3 at 25°C in warehouse fumigation and 112g/m~3 at 10 °C, 80g/m~3 at 15°C, 64g/m~3 at 20°C and 48g/m~3 at 25°C in tarpaulin fumigation, respectively under conditions of 24-hour fumigation with 50% loading of wood packing materials
