Embodiment 1

[0026] Embodiment one: Jujube fruit fly selectivity assay to jujube fruit volatiles

[0027] 1.1 Determination of the attracting effect of six kinds of jujube fruit volatiles on Jujube fruit flies

[0028] Insect source and rearing: In July 2016, jujube fruits with larvae were collected in Qiongkule Village (42°53′45″N, 89°3′29″E) in Aidinghu Township, Turpan City in July 2016. The jujube fruit is brought back to the room and placed on the sand, so that the larvae will naturally drop the fruit and enter the soil to pupate. The obtained pupae and adults were raised under the conditions of 28±1° C., RH35%±5%, and photoperiod 14L:10D. Adults were collected every 3h-5h during the eclosion period. Cages were divided according to the eclosion date, and the male and female worms were reared separately with 20% honey water and 20% yeast extract (1:1 by volume).

Embodiment 2

[0051] Embodiment two: Jujube fruit fly adult attractant

[0052] The present invention provides an attractant for fruit fly adults, which comprises one or more of myristic acid, ethyl myristate, ethyl laurate, ethyl palmitate, ethyl linoleate and ethyl oleate .

[0053] Preferably, the present invention provides a jujube fruit fly adult attractant, comprising 40-60 parts of ethyl linoleate, 45-55 parts of ethyl oleate, 35-45 parts of ethyl palmitate, myristic acid 30-40 parts of ethyl ester, 25-35 parts of myristic acid and 12-20 parts of ethyl laurate.

[0054] Preferably, the present invention provides a jujube fruit fly adult attractant, comprising 50-60 parts of ethyl palmitate, 45-55 parts of myristic acid, 30-50 parts of ethyl laurate, ethyl myristate 30-40 parts, 20-30 parts of ethyl linoleate and 16-24 parts of ethyl oleate.

Embodiment 3

[0055] Embodiment three: the application of jujube fruit fly adult attractant

[0056] The invention provides an application of an attractant for jujube fruit fly adults in jujube fields. When attracting jujube fruit fly male adults, the yellow sticky board is hung close to the crown of jujube trees when the sunlight intensity is lower than 60%. The maximum cross-sectional size of the sticky insect board is 30cm*26cm. The yellow sticky insect board is pre-coated with jujube fruit fly adult attractant. The jujube fruit fly adult attractant includes 40-60 parts of ethyl linoleate and 45 parts of ethyl oleate- 55 parts, 35-45 parts of ethyl palmitate, 30-40 parts of ethyl myristate, 25-35 parts of myristic acid and 12-20 parts of ethyl laurate, the distance between the yellow sticky board and the ground The height is 1.5m-1.7m, after 9 days, replace the yellow sticky insect board.

Abstract

The invention discloses a jujube fruit fly adult attractant and its application. The attractant comprises myristic acid, ethyl myristate, ethyl laurate, ethyl palmitate, a mixture, ethyl linoleate and ethyl oleate One or more of the esters; in application, different attractant formulas are provided for male and female adults of Bactrocera jujuba, and the volatile matter of jujube fruit is used as the attractant and used in conjunction with the yellow sticky insect board, which has good attracting effect and special With the characteristics of strong sex and no adverse effect on the environment, the attracting activity of the 6 substances of the formula to Bacteralis japonicus was tested with a four-arm olfactometer, and the results showed that: The selective rate of acid was relatively strong, both above 30%; the selectivity of males to ethyl linoleate and ethyl oleate was relatively strong, both above 25%. Through continuous 8-day monitoring in the field, the attracting effect of volatile myristic acid was strong, the maximum trapping amount reached 23 head / animal, and the average trapping amount was 18.2 head / animal.

Description

technical field [0001] The present invention mainly relates to the technical field of forestry pest control, in particular, the present invention relates to the technical field of an attractant. Background technique [0002] Jujube fruit fly (Carpomya vesuviana Costa) is one of the important quarantine pests of jujube trees. In the comprehensive control of Jujube fruit fly, the traditional yellow sticky board is used as the attractant to monitor and trap adults, but the specificity of the yellow sticky board is not strong, and the effect is not ideal. The biological control of fruit fly pests can also use methods such as parasitic natural enemies, attractants and sterile insect techniques. The attractants are specific, easy to use, and do not pollute the environment. Attractants for fruit fly pests can be roughly divided into the following three categories: chemical compounds such as methyl eugenol and lureketone, hydrolyzed proteins and plant extract attractants.
