【摘要】 小菜蛾是典型的世界性害虫。本文综述了国内外有关温度对小菜蛾生长发育、存活、繁殖和种群增长等生物学特性影响的研究概况,提出了开展变温条件下小菜蛾生物学特性研究的重要性,这将有助于进一步弄清小菜蛾种群在田间自然条件下种群消长规律的内在机理,为利用当地的气象资料推测小菜蛾在某一时间段内的发生动态,确定防治适期,科学有效地指导防治提供理论依据。更多还原

【Abstract】 The diamondback moth(DBM),Plutella xylostella(L.) was a typical cosmopolitan pest.This article summarized the progress on effect of temperature on development,survival,reproduction and population growth of the DBM in foreign and domestic studies over the past few decades.It is important and necessary to carry out researches on biological characteristics of the DBM under variable temperatures,which will be helpful to verify the mechanism of the DBM’s population dynamics in the field,forecast its occurrence based on meteorological data,determine the optimum control time and provide scientific guide for prevention and control of the DBM.更多还原
