Problems solved by technology

Although the large-area application of attractants to prevent and control the grape moth has certain effects, but its use cost is relatively high, and the cost of manual replacement is also high
The method of using pheromones to interfere with the mating of insects has gradually come into people's field of vision, but the simple use of pheromone components as a mating interference agent requires a large amount and high cost
Pheromone analogs with similar chemical structures to natural pheromones are more efficient than pheromones and are suitable for large-scale applications, but it is still a difficult problem to screen out highly efficient pheromone analogs

Embodiment 1

[0018] Example 1 Field Test of Sex Pheromone Analogues (Emulsion Polymerization Microcapsules) of Toricula vine

[0019] Select grape varieties, growing conditions, and consistent fertilizer and water management conditions. Contiguous vineyards with an area of ​​more than 10 mu are used as test fields, and traps and lure cores are set up for the trapping test of grape moths. Three traps are set for each lure core. Sticky insect board trap (traps purchased from Zhangzhou Yinger Agricultural Technology Co., Ltd.), the core composition is acrylic and / or methacrylic monomers as wall materials, and the sex pheromone prepared by emulsion polymerization is similar to Object microcapsules, set sex attractant control (SP) and blank control (CK) at the same time, wherein sex attractant control (SP) is the compound {(E, Z)-7,9-dodecane that contains following mass ratio En-1-ol acetate (E7, Z9-12: Ac), (E, Z)-7,9-dodecadien-1-ol (E7, Z9-12: OH) and (Z) -9-dodecene acetate (Z9-12: Ac)...

Embodiment 2

[0025] Example 2 Field test of sex pheromone analogue (composite aggregation method microcapsules) of the grape moth

[0026] Select grape varieties, growing conditions, and consistent fertilizer and water management conditions. Contiguous vineyards with an area of ​​more than 10 mu are used as test fields, and traps and lure cores are set up for the trapping test of grape moths. Three traps are set for each lure core. The sticky insect board trap (the trap is purchased from Zhangzhou Yinger Agricultural Technology Co., Ltd.), the core composition is gelatin and / or gum arabic as the wall material, and the sex pheromone analogue microcapsules synthesized by the composite coacervation method, At the same time, a sex attractant control (SP) and a blank control (CK) are set, wherein the sex attractant control (SP) is a compound containing the following mass ratio {(E, Z)-7,9-dodecadiene-1- Alcohol acetate (E7, Z9-12: Ac), (E, Z)-7,9-dodecadien-1-ol (E7, Z9-12: OH) and (Z)-9-dec...

Abstract

The invention discloses a sex pheromone analogue for preventing and controlling lobesia botrana, and application of the sex pheromone analogue. The general formula of the sex pheromone analogue is ROCOCnHaXb. In the general formula, R is one of (E, Z)-7, 9-dodecadienyl and (Z)-9-dodecenyl, X is a halogen atom, n, a and b belong to N*, a+b=2n+1, a is more than or equal to 0 and less than or equal to 2n, and b is more than 0 and less than or equal to 2n+1. The sex attractant for the lobesia botrana can be applied to pest quarantine, insect pest situation monitoring, large-scale trapping and mating interference of the lobesia botrana, thus having a great significance for the comprehensive management of the lobesia botrana. The sex attractant analogue for the lobesia botrana is simple to prepare, diverse in dosage forms, simple to use, strong in trapping ability and good in stability; furthermore, the sex attractant analogue is single in action object, non-resistant, environmentally-friendly, non-toxic to human and animals, high in stress resistance, not afraid of wind, sun and rain, and long in effect lasting period; the prevention and control effect can be maintained for 30 days or more.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to a sex pheromone analog used for preventing and controlling the vine toricula. Background technique [0002] Lobesia botrana (Denis et Schiffermuller), belongs to Lepidoptera (Lepidoptera), Tortricidae (Tortricidae), flower wing small tortrina (Lobesia), is a serious damage to a variety of economic plants flowers and It is a worldwide pest of fruit and is listed as an important entry plant quarantine pest in many countries in the world, including my country. The grape moth mainly feeds on the flowers and berries of grapes with its larvae. If mature grape bunches are attacked by moths, the berries will be infected with botrytis and further rot. In addition to grapes, the moth also affects olives, blackberries, cherries, nectarines, persimmons and pomegranates. With the increase of international fruit trade, the risk of grape tortrix invading my country has further incre...
