Abstract

Forest fire effect on population density of the pine needle gall midge, Thecodiplosis japonensis Uchida et Inouye.

Abstract

Studies were conducted in damaged red pine [Pinus densiflora] forests in Gosung-gun, Kwangwon province, Korea Republic, following forest fires in April 1996. There was a reduction of 86% and 80% in pine needle gall midge (Thecodiplosis japonensis) larvae and adult populations, respectively. It is predicted that adults will migrate from slightly damaged forest areas to nearby undamaged forests. The fires did not alter the period at which adult insects emerged.
