Comprehensive Prevention And Control Technology Research Of Primary Pests In Guangxi Silkworm And Mulberry Original Seeds Breeding Base

Just so-called "fine seed is the guarantee of industry development",Guangxi sericulture achieved great achievement in recent years with the fundamental guarantee of fine seeds,so that the original seeds is particularly important.With the increased area of Guangxi mulberry fields the pest problem become more and more serious,largely use of chemical pesticide lead to silkworm poisoned during rearing sometimes,the cross infection of pests and silkworm lead to bigger pressure of pebrine disease prevention.Pest and chemical pesticide influence the development of sericulture industry seriously,in order to guarantee safety production and health development of Guangxi sericulture,pest prevention in original seeds base is very important.This article rely on Guangxi silkworm and mulberry original seeds base to investigate the primary pest variety of mulberry tree,and find out the dynamic changes of pest in rest period,developing period and production period of mulberry fields.Using new equipment with new technology to prevent the primary pest in mulberry field,the result shows that low capacity and high efficiency plant protection aircraft control of mulberry moth larvae,500 times 40%dimethoate and 77.5%dichlorvos EC control efficiency as high as 93.75%,yellow sticky board control of mulberry whitefly was as high as 37.91%,blue sticky board control Mulberry Thrips control efficiency up to 51.43%,the prevention and control of Mulberry Thrips irrigation facilities up to 91.53%,high speed water spray control equipment mulberry leaf mite average control effect reached 90.56%,the equipment and related control measures have achieved good control effect,has good application value.In addition,agricultural facilities like net house isolate mulberry trees from pest and prevent cross infection of pests and silkworm,which worth further study.Perfecting the comprehensive prevention and control technology system and formulating prevention and control plan of each period rely on the research result and the actual situation of base.The above get good application effect,which has changed the chemical prevention as the single method to prevent and control pest,reached the goal to reduce the use of some chemical pesticide.
