Abstract

The invention discloses a bisexual adult attractant for colorado potato beetles, which comprises the following components by weight percent: 70-80% of component I and 20-30% of 2-phenylethanol, wherein the component I is methyl phenylacetate or beta-caryophyllene. The invention simultaneously discloses another bisexual adult attractant for the colorado potato beetles, which comprises the following components by weight percent: 4-7% of methyl phenylacetate, 90-95% of beta-caryophyllene and 1-3% of 2-phenylethanol. By applying the attractant, occurrence dynamics of the colorado potato beetles in a field can be monitored, chemical control can be guided, and the colorado potato beetles can be simultaneously directly controlled through the mass trapping method.
