The effects of temperatures on embryonic and post-embryonic development and on reproduction of Ditylenchus angustus were investigated. The rate of embryonic and post-embryonic development was linear ranging from 15 to 30 degree C. The lowest mortality and the highest egg hatching occurred at 25 degree C. The eggs failed to hatch at 35 degree C. The developmental zero degree for embryonic and post embryonic development were calculated to be 10.6 and 10.0 degree C. The development of D. angustus on Botrytis cinerea from egg to egg took 8.9, 9.8, 17.2 and 34.0 days at 30, 25, 20, and 15 degree C, respectively. Twenty five days after inoculation on fungal mat of B. cinerea, D. angustus was multiplied to 32,800, 16,000 and 9,000 from the original population of 200 at 25, 30 and 20 degree C, respectively
