Bactrocera dorsalis slow-release type attractant

Abstract

The invention discloses a bactrocera dorsalis slow-release type attractant which includes the following components by mass percent: 80-90% of methyl eugenol, 5-10% of a synergist and 5-15% of a slow-release agent, wherein the synergist adopts one or more of orange oil, psidium guajava essential oil, mango essential oil, loquat flower essential oil and carambola essential oil; the slow-release agent adopts one or more of vegetable oil and gutter oil. The bactrocera dorsalis slow-release type attractant provided by the invention adopts a simple, effective and pollution-free slow-release and synergistic technology, and includes not only methyl eugenol active substances but also plant essential oil which has a synergistic effect, as well as the slow-release drug for increasing the drug effect duration, so as to prolong the attraction time and improve the attraction effect of the bactrocera dorsalis attractant, and satisfy technology requirements for effective and long-lasting prevention and control. The raw materials used by the bactrocera dorsalis slow-release type attractant have the characteristics of being environment-friendly, low in cost and long in drug effect duration.
