However, the volatility of hexyl acetate is relatively strong, and the duration needs to be improved; (4) slow-release attractant, which increases the attractant time. At present, most patented technologies borrow medical slow-release technology and use cyclodextrin and other substances to embed Attractant, the technical data shows that cyclodextrin is used for slow release, and it needs to be processed accordingly in order to play a slow release effect; there are also methyl cellulose and sodium benzoate, these two substances are insoluble in methyl eugenol, so Can only be made into paste preparations

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.
Description
Technical field: [0001] The invention belongs to the field of agricultural pest control, and in particular relates to a slow-release attractant for Bactrocera dorsalis. Background technique: [0002] Bactrocera dorsalis (Hendel) belongs to Diptera (Diptera), Tephritidae (Tephritidae), is an important pest of fruit crops, the pest is mainly distributed in Guangdong, Guangxi, Hainan, Hunan, Hubei, Sichuan, Chongqing, Guizhou, Fujian, Yunnan, Taiwan and other provinces. It parasitizes and harms guava, mango, peach, carambola, banana, Sanhua plum, custard apple, sweet orange, lime, citrus, lemon, apricot, loquat, apple rose, grape, fig, walnut, wampee and other fruits. [0003] Bactrocera dorsalis has strong fecundity and great harm. In its endemic areas, the damage rate of the host fruit is extremely high, and in severe cases, it may even become extinct. The damage of Bactrocera dorsalis is manifested in laying eggs under the fruit skin and forming egg-laying holes on the su...
