Technical Field

The invention belongs to the technical field of biological control of pests, and particularly relates to a cow dung-derived attractant for controlling Holotrichia parallela imagoes.

Background

The Holotrichia parallela occurs for 1 generation in 1 year, larvae are 3 years old, wherein the 3 years old has the longest calendar period and the largest food consumption, the pest period almost runs through the whole growing season of crops, and in addition, the Holotrichia parallela is latent in soil to cause pest, so that the control difficulty is greatly increased, and the Holotrichia parallela is a soil pest which is acknowledged in the world and is difficult to control. Because the larvae of the Holotrichia parallela are hidden underground as harmful pests, comprehensive prevention and control are carried out by adopting the principle of combining underground and overground prevention and control and combining larvae and adult prevention and control, and the adult prevention and control can achieve the effect of twice with half the effort.

The Holotrichia parallela imago has oviposition preference to host plants, has stronger tendency to insufficiently decomposed organic fertilizers and putrefactive organic substances, and likes to lay eggs in the Holotrichia parallela imago; the application of the organic fertilizer which is not fully decomposed often causes the grubs to be seriously generated, and the attractability of the fully decomposed organic fertilizer to the scarabs is greatly reduced. Another research shows that the induction effect of the cow dung leaching liquor on the scarab beetles is obviously stronger than that of the castor leaf leaching liquor and the chemical attractant, which shows that the induction effect of the putrefactive organic matters on the adult scarab beetles is probably stronger than that of host plant volatile matters. Therefore, the research on the induction of the Holotrichia parallela imagoes by the cow dung source volatile matters has important significance for the ecological prevention and treatment of Holotrichia parallela.

Disclosure of Invention

The invention aims to provide a cow dung source attractant for preventing and controlling Holotrichia parallela imagoes so as to improve the effect of comprehensively treating Holotrichia parallela.

The main components in the cow dung volatile matter are obtained through a GC-MS test, the electrophysiological activity of the Holotrichia parallela on the components of the cow dung volatile matter is measured through an insect antenna potential test, and the volatile matter with strong electrophysiological activity is subjected to an attraction effect test in a field.

The effective component of the attractant is Butyric acid (butyl acid).

Preferably, the mass fraction of butyric acid is 10%.

The preparation method of the cow dung-source attractant for preventing and treating the Holotrichia parallela imago comprises the step of diluting Butyric acid (butyl acid) into a Butyric acid solution with the mass fraction of 10% by taking paraffin oil as a solvent.

The cow dung-source attractant for preventing and treating the Holotrichia parallela imago is used for attracting the Holotrichia parallela imago.

Compared with the prior art, the invention has the following excellent effects: the cow dung-source attractant for preventing and treating the Holotrichia parallela imago has good prevention and treatment effects on Holotrichia parallela, and can not cause the Holotrichia parallela to generate resistance; the preparation method is simple, the preparation cost is low, the method is harmless to human and livestock, the environment is friendly, and the method has important significance for comprehensively treating the Holotrichia parallela.
