摘要
50年代初期,稻瘿蚊在本省部分山区、丘陵区发生,间歇猖獗;50年代中期至60年代,全省基本实现双季连作稻后,稻瘿蚊发生为害明显减少。70年代以来,部分地区大面积种植早稻:(1)迟熟品种,迟插;(2)三季连作稻和中稻;(3)晚稻寄秧,植期延长。为稻瘿蚊创造了良好的繁殖环境和转移桥梁,遇到适宜的气候条件,便猖獗成灾。80年代以后,全省恢复了双季稻连作制,采用早、中熟品种适时移植,使用喹硫磷等有效农药,作好晚稻秧田防治等综合防治措施,较有效地控制了稻瘿蚊的发生为害。
In early 1950s,Orseolia oryzae Wood-Mason was rampant intermit-tently in some mountain areas and hill lands in Guangdong Province.Asthe double cropping rice system became popular throughout the prov-ince from middle 1950s to 1960s,the damage of this insect decreasedobviously.However,the damage was inverted to an outbreak situationsince 1970s,as the late-maturing varieties and late-transplanting ofearly rice,the triple-cropping system or mid-season rice,heel-in seedlingand longer transplanting period,which provided favourable conditionsfor multiplication and transmission of this insect,were adopted. The occurrence and damage of this insect have overcome effectivelysince a series of integrated control methods such as double croppingrice system was resumed in whole province,to use early-middle maturingvarieties of early rice,the application of effective insecticides such asquinalphos,chlorpyrifos,sulfotep,isocarbophos,carbofuran,etc.,andthe control in late-rice nursery,were realized.
