Porphyrophora ningxia chemical attractant

Abstract

The invention relates to a porphyrophora ningxia chemical attractant. The active ingredient of the attractant is (-)-beta-pinene which is volatile smell substance released by glycyrrhiza uralensis and is a chemical communication substance between the porphyrophora ningxia nymph and glycyrrhiza uralensis. Experimental results show that the trapping effect is prominent when the concentration of (-)-beta-pinene as an attractant of the porphyrophora ningxia is 100mug/mul. The attractant can be used for trapping and preventing porphyrophora ningxia nymph, can also be used as field porphyrophora ningxia monitoring substances, and can reduce the side effect due to the use of chemical pesticide. The porphyrophora ningxia chemical attractant can establish a material basis for developing a sustainable and environment-friendly porphyrophora ningxia prevention technology and reducing the dosage of chemical pesticide.

Description

technical field [0001] The invention belongs to the technical field of pest control and monitoring, and in particular relates to a chemical attractant for licorice cochineal scales. Background technique [0002] Licorice cochineal scale (Porphyrophora ningxiana Yang) belongs to Homoptera, Porphyrophora ningxiana genus, Porphyrophora ningxiana genus, adults are dioecious, and females are wingless. Parasitic on the rhizome of licorice, causing the root of the plant to rot and dry, and causing serious damage to artificially planted licorice. The degree of damage increases year by year with the planting years of licorice. The characteristics of large reproduction, fast diffusion and difficult control are one of the main obstacles restricting the healthy development of the artificial licorice industry. [0003] The adults of the licorice cochineal scales unearthed in late August and mate and lay eggs in the soil in disordered sacs. At the end of September, the eggs hatched, and ...
