The habits of longicorn beetles

Longicorn beetles have long tentacles. Before seeing them, many friends thought they were the same animals as cattle. In fact, longicorn beetles are insects and very small. So do you know the habits of longicorn beetles? Let's have a look together!

First, the habits of longicorn beetles

Longicorn beetles need to be replenished during the larval stage, and the pollen, twigs, bark and sap around them are their sources of nutrition. When it comes to the adult stage, the life span is generally more than 10 days to 1-2 months, and the life span of males is shorter than that of females, which is harmful to the trunk.

How to hunt and kill longicorn beetles

1. Catch and kill adults

In general, during the peak period of longicorn beetle adults from May to July, it is often checked that the adults rest in the trees or fly low in the forest. Some adults have false death, shake the branches violently, and the adults fall and kill.

2. Killing eggs and young larvae

Longicorn beetles lay eggs on the branches, and some species of oviposition grooves are obviously easy to find. before the young larvae are eaten into the xylem, there is fresh sap resin and reddish-brown dung debris on the branches, scraping the bark with a sharp knife, searching carefully, killing eggs and larvae, or beating with hammers, or applying pesticides. This method is only suitable for the species with low branches, oviposition grooves and obvious damage to young larvae.

Longicorn beetles as natural enemies of trees, it is indeed difficult to eradicate all of them. I hope the above methods will also be effective for you.
