Technical Field
The invention belongs to the field of pest control, and particularly relates to a drosophila attractant prepared from an extract of leaves of a plant of the genus acanthopanax.
Background
Along with the attention of people on the health and safety of food and drink, green organic fruits are more and more popular. The blueberry planting industry in Guizhou is continuously expanded, the problem of blueberry diseases and insect pests is getting more and more serious, and fruit flies (Drosophila) are one of the most serious pests harming blueberry fruits. The fruit flies lay eggs on mature blueberry fruits in rainy and high-temperature seasons, the surfaces of the damaged fruits are slightly sunken, worm holes with the sizes of needle points are formed in the surfaces of the fruits, hatched larvae eat the fruits and are damaged, and insect dung exists in the fruits; damaged fruits become soft, juice overflows and falls, so that the yield is reduced and the quality is deteriorated. Meanwhile, the safety, commodity value, fresh sale, storage, processing and the like of fruit damaged by fruit flies are seriously affected.
Besides the blueberries, fruit flies can also harm various fruits such as cherries, grapes, raspberries and blackberries, and seriously affect the quality of the fruits and the economic income of fruit growers.
Therefore, how to provide a drosophila attractant which has good control effect, no pollution to fruits and no pollution to the environment becomes a technical problem which needs to be solved by the technical personnel in the field. In order to prevent fruit flies from being harmed by adding natural plants, effectively reduce the adding amount of the artificially synthesized insect-resist agent and further effectively ensure the food safety, the inventor selects acanthopanax plants as experiments.
Acanthopanax (academic name:Acanthopanaxmiq.) is a genus of Araliaceae, deciduous shrub or small tree. There are currently 37 (not including varieties) of Araliaceae Acanthopanax species found worldwidePlants, mainly distributed in asia. The Chinese has 26 varieties of 18 varieties, which account for the first place in the world, are widely distributed in various provinces of China, and are the most abundant in Yangtze river basin, wherein the most common varieties are acanthopanax gracilistylus, acanthopanax senticosus and acanthopanax giraldii harms. The acanthopanax plant has medicinal value, has the functions of resisting inflammation, stress, arrhythmia, platelet aggregation, tumor, smooth muscle excitation, ulcer and the like, and can influence immune system and substance metabolism.
