Occurrence Status of Pest in Pinus elliottii ×P.caribaea Introduction Trial Plantation in Fujian Province
摘要
Abstract
After the investigation on pest in 596.2 hm2 hybrid pine ( Pinus elliottii ×P.caribaea) introduction trial plantation of 27 counties in Fujian Province during 2009~2010,16 pests were found.But the distribution area of 6 pests of Pestalotiopsis funerea Desm.,Lecanosticta acicola Sydow,Sphaeropsis sapinea(Fr.:Fr.)Dyko&(Sutton,Dichocrocis punctiferalis Guenee,Dioryctria rubel-la Hampsom,Dendrolimus punctatus Walker were greater than other pests distribution area ,each of their distribution area was above 10%of the total trial plantation area.Especially , the distribution area of Pestalotiopsis funerea Desm.owned 48.53%.The species number and distribution area of pests increase with stands age ,damaged mainly by Dichocrocis punctiferalis Guenee,Dioryctria rubella Hampsom to cause infected young shootes withering and arbuscular bull in young plantation .The damage on hybrid pine infected by Sphaeropsis sapinea( Fr.:Fr.) Dyko & Sutton and Lecanosticta acicola Sydow were getting more and more serious with age of stands.Through the statistical analysis ,there was no obvious difference between south subtropics region and middle sub -tropics region on the species number of pests and proportion of their distribution area in their region plantation area ,but these pests couldn ’ t take serious damage in south subtropics reg-ion.The result showed it was more suitable for growth of hybrid pine in south subtropics re -gion than middle sub-tropics region.关键词
