[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).
