A FORMULA OF ATTRACTANT FOR MEGASTIGMUS SABINAE AND ITS PREPARATION METHOD AND APPLICATION

The present invention discloses a formula of attractant for Megastigmus sabinae and its preparation method and application, and relates to the field of biological control technology. The attractant formula components include 3-carene, myrcene and alpha-epoxypinane. The concentration ratio between the three components is 1 : 10 : 10. Based on this concentration ratio, each component is dissolved in a liquid paraffin oil solvent to obtain an attractant. By using several chemical active substances with attractive effect in the invention, the plant-derived attractant can monitor the Megastigmus sabinae for a long time, so as to detect the change of the relative abundance of the Megastigmus sabinae, and then determine the behavior and population change of the Megastigmus sabinae in a long time, and determine the driving factors that may change, so as to control the Megastigmus sabinae more scientifically and effectively, and improve the control effect of the Megastigmus sabinae.
