Abstract

An attractant for apple-tree trunkborers is mainly prepared from the following raw materials in parts by weight: 50 parts of apple tree wood extractive, 10-20 parts of alpha-pinene, 15-25 parts of beta-pinene, 5-15 parts of cedrol, 4-8 parts of farnesene, 2-8 parts of limonene, 1-5 parts of turpentine, and 3-7 parts of terpinolene. Compared with the prior art, the obtained attractant is substantially improved in average quantity of attracted insects and average persistent-effect time, is specially applied to attraction of apple-tree trunkborers, and is protrude in attraction effect.

Description

technical field [0001] The invention relates to an attractant for apple tree borer, which is applied in the field of agriculture. Background technique [0002] Stem borers are pests that drill into the trunk and branches, feed on the phloem and xylem, and cause the death of garden trees. The introduction of a large number of dry borer pests has increased the harm to my country's forestry resources. For fruit trees, it causes malnutrition of the fruit trees, reduces fruit production, and even causes the fruit trees to eventually die. Therefore, there is a need to develop effective methods for controlling stem borer pests. [0003] Bore pests pose a great threat to trees. The traditional spraying method can only be sprayed on the skin of trees, but cannot penetrate into the part where the borers are located, and cannot effectively kill the borers. The injection method is time-consuming and labor-intensive. The use of attractants to lure pests out for hunting can greatly sa...
