The invention relates to a method for preventing and controlling insect pests by parasitic wasps, which belongs to the technical field of biological control. Its characteristic is the use of parasitic wasps parasitic characteristic of the virus into the target pest egg surface, resulting in early larvae disease and death induced by target insect populations forming virus epidemic, to control insect pest effectively. The main technical features are: Based on insect virus (N virus, G virus, C virus) has three major characteristics, specific, efficient and safe and it is easy to form virus epidemic in the pest population according to parasitoids for insects, high technology after the treatment of virus directly transmitted to the target pest eggs the surface of the newly hatched larvae feeding on crop disease, pest control in the prevention and treatment of victims before will be below the threshold. The utility model has the advantages of solving the problem that virus release and uptake of newly hatched larvae of virus, parasitic wasps play not only the media is a pioneering role in pest control; the goal is clear, safe and harmless to people and animals, no environmental pollution prevention, low cost, convenient use; reduce farmers' labor intensity, good control effect (91%), long duration; can be widely used in agriculture, forestry, fruit and vegetable pest control, with significant economic benefits, ecological benefits and social benefits.
【技术实现步骤摘要】
【国外来华专利技术】本专利技术是寄生蜂传递病毒防治害虫方法,是属于生物防治
历年来,无论是应用生物农药还是化学农药防治害虫,一般都是采用机械喷雾的方法,将农药喷洒在作物表面,使害虫取食后得病而死。利用昆虫病毒防治害虫对人畜安全、无污染、防治效果好,在昆虫种群中易形成病毒流行病和在较长时期内控制次代害虫的发生等特点已被人们所公认。然而,这种靠机械喷洒的传统方法使用成本高,用药量大、浪费严重,也污染环境。常常是发现害虫危害时,作物已受到一定程度损失才开始防治。此时应用生物防治,一时也难奏效。因此,Smirnoff(1980)利用胡蜂吞食感染病毒的昆虫,然后将其放入林间传播病毒。戴冠群(1986)利用鸟取食带毒的昆虫或食物,通过鸟类传播病毒。Harry(1994)利用蜜蜂传递HzMNPV防治美洲棉铃虫。杜家伟(1994)利用性引诱剂吸引雄蛾,使雄蛾沾染病毒后与雌蛾交配,将病毒传递给雌蛾,让雌蛾带毒产卵。这些措施虽然取得了一定的进展,但难以起到防治害虫的效果。本专利技术的目的是提供了一种卵寄生蜂传递病毒防治害虫的方法,以昆虫病毒(N病毒、G病毒、C病毒)所具有的三大特色,专一、高效、安全和在害虫种群中易形成病毒流行病等特点为依据(彭辉银1986,1992),对病毒作高技术处理,以寄生蜂为媒介,通过寄生蜂的腹足和触角将病毒传递到目标害虫卵表面,使初孵幼虫摄食带毒的卵壳罹病死亡,使目标害虫控制在作物受害之前的一种防治措施。为实现上述目的,本专利技术采用以下技术措施首先是对已寄生松毛虫赤眼蜂的宿主卵表面进行清洁处理,制备成一定规格大小的寄生蜂卵卡,然后通过专用雾化设备将绿叶松微型生物 ...
