本文叙述的是廉价大量生产Neoaplec-tana属几种线虫的新方法。Neoaplectana属线虫是广谱性的昆虫寄生性线虫,是一种虫、菌共生的复合体。其共生菌是Xenorhabdusnematophilus即Achromobacter nematohil-us及X.sp。在对害虫的防治中,主要通过三龄带鞘动虫,也称感染期幼虫,由寄主孔口,主要是口腔侵入消化道后,穿过肠壁进入血腔,并将其共生菌排到寄主血腔内,使寄主昆虫在24—36小时内因得败血症而死亡。 This article describes a new method for mass production of several species of Neoaplec-tana at low cost. Neoaplectana is a broad-spectrum nematode parasitic nematode that is a complex of parasites and bacteria. Its symbiotic bacteria are Xenorhabdus nematophilus, namely Achromobacter nematohil-us and X. sp. In the control of pests, mainly through the third instar sheath insect, also known as infection larvae, by the host orifice, mainly after the oral invades the digestive tract, through the intestinal wall into the blood cavity, and its symbiotic bacteria discharged to The host blood cavity, so that the host insects within 24-36 hours due to sepsis and death.
