摘要
中国梨木虱(Psylla Chinese Yang et Li)是新传入新疆的危险性害虫,为减少其灾害损失,本文将梨木虱灾害发生的气象等级进行划分,并通过对库尔勒梨园实际调查和历史资料的分析研究,寻找与梨木虱发生发展关系密切的气象因子,建立梨木虱卵量等级预报模型。结果表明,在2000-2002年和2010年,高温是抑制梨木虱生长发育的最主要气象因子;在0～22.5℃气温范围内其生长发育随温度升高而加快,在22.5℃以上随温度升高而减缓,35℃以上时就呈现非常明显的抑制作用。用该模型对梨木虱发生灾害进行预测检验,效果良好,这为梨木虱的有效防治提供了科学依据,对农业防灾减灾和农业生产的可持续发展具有重要的指导意义。
Psylla Chinese Yang et Li was a new introduction fatalness pest in Xinjiang,China.In order to reduce loss,we measured off meteorological grades of calamity caused by Psylla Chinese Yang et Li.A forecasting model of eggs of Psylla Chinese was built by using meteorological conditions which were firmly connected with the development of Psylla Chinese through actual investigation data and historical meteorological data.The results showed that high temperature was the major meteorological factor that could obstacle the development of Psylla Chinese from 2000 to 2002 and in 2010.The development rate of Psylla Chinese increased quickly with temperature increased under 22.5℃,and increased slowly with temperature increased above 22.5℃,restraining when temperature increased to 35℃.The model was tested and confirmed well with the occurrence of Psylla Chinese from 2000 to 2002 and in 2010.This provided scientific basis for effective prevention on Psylla Chinese.And it had important guidance significance for prevention and reduction disaster and sustainable development of agriculture practice.
