Description

Technical Field

[0001] This utility model relates to the field of forestry pest control technology, specifically a suspended larch caterpillar larvae capture device. Background Technology

[0002] Larch caterpillars are one of the major pests of larch and other coniferous forests. Their larvae feed heavily on the needles, severely affecting the growth and development of trees and even causing their death. Traditional control methods, such as chemical pesticide spraying, can control the number of pests to some extent, but they can easily cause environmental pollution and may kill beneficial organisms and disrupt the ecological balance. Physical control methods, on the other hand, are more environmentally friendly.

[0003] In the prior art, utility model patent CN201821674939.6 discloses a larch caterpillar larvae trapping device, including a flexible board, which is a single-layer double-sided corrugated board. The four sides of the flexible board are a first side edge, a second side edge, a first end edge, and a second end edge. The first side edge and the second side edge are opposite each other and are both corrugated edges, while the first end edge and the second end edge are opposite each other and are both straight edges. On each corrugated surface of the flexible board, from the inside out, an insect-adhesive layer and a protective film are sequentially arranged. A first hook and loop fastener and a second hook and loop fastener are respectively arranged on the first end edge and the second end edge of the flexible board. The first hook and loop fastener and the second hook and loop fastener are male and female, respectively. After removing the protective film, the flexible board is tightly fitted into the trunk of the tree in a cylindrical shape by the first hook and loop fastener and the second hook and loop fastener.

[0004] The aforementioned patent provides a device for capturing larch caterpillars. This device can be arranged around a larch tree to adhere to and capture passing larch caterpillars. However, since the device is exposed to the outside world, its stickiness will decrease with sun exposure and weathering. Even when it is windy, dust particles carried by the wind will adhere to the device, reducing its stickiness and ultimately reducing its lifespan. Utility Model Content
