Abstract

The invention discloses a sycamore tree trunk borer attractant. The sycamore tree trunk borer attractant is mainly prepared from the following components in parts by weight: 50 parts of sycamore tree wood extract, 15-25 parts of alpha-pinene, 10-20 parts of beta-pinene, 4-14 parts of acetaldehyde, 4-8 parts of acetone, 3-9 parts of longifolene, 1-5 parts of caryophyllene and 2-6 parts of camphene. Compared with the prior art, the insect attraction average quantity and the average lasting effect of the attractant are remarkably improved; and the attractant can be specially used for attracting sycamore tree trunk borers and the attraction effect is prominent.

Description

technical field [0001] The invention relates to an attractant for sycamore tree borers, 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 garden trees, it causes malnutrition of the trees, produces a lot of dirt, and even causes the 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 save manpow...
