How Big Is the Titan Beetle? These Are the Dangers It Brings to Plants

Longhorn beetles are the general name for insects in the family Cerambycidae, so named because they are as strong as an ox and skilled at flying through the sky. There are many species, and one of them, the titan beetle, is one of the largest insects in the world and also one of the most mysterious creatures. So, how big is the titan beetle?

1. A Brief Introduction to Longhorn Beetles!

1. What other names do longhorn beetles have?

The longhorn beetle got the name “longhorn” because it is as strong as an ox and skilled at flying through the sky, and it got the name “sawyer” because it makes a “crunch, crunch” sound like sawing wood. In some places it is called “water ox”, “buffalo”, “spring ox” and so on.

2. Is the longhorn beetle a beneficial insect or a pest?

The longhorn beetle is a pest. Most species damage woody plants, some damage herbaceous plants, and a few damage timber, buildings, houses and furniture. During the larval stage they bore into trunks, branches and roots, while the adults feed on pollen, tender bark, young shoots, leaves, roots, sap, fruit, fungi and so on.

3. Do longhorn beetles bite people?

Longhorn beetles have very powerful chewing mouthparts that can bite through very hard wood, so they can bite people too, so be careful not to get your hand bitten when handling them. The saliva of longhorn beetles is toxic. After being bitten, squeeze out the blood immediately, then wash the wound with soapy water.

2. How Big Is the Titan Beetle?

1. The titan beetle is one of the largest insects in the world and lives in the rainforest regions of South America. Its body length can reach up to 16.7 cm. Because it is so large and heavy, it generally cannot take off directly from the ground and can only take off from tree branches.

2. The titan beetle is one of the most mysterious creatures. Its larvae are said to live in tree holes and feed on rotting wood, but no one has ever found them. Judging by the size of the tree holes, the pupa is about as big as a small tomato.

3. The titan beetle is very strong. It has powerful mandibles that can bite a wooden pencil in half. Like other longhorn beetles, when in danger it moves its head up and down, causing the shell on its neck to rub together and produce a hissing warning sound.

4. Adult titan beetles never feed, which is one way they differ from most other longhorn beetles. Their sole purpose in growing up is to mate and reproduce, and the energy their bodies need at this time comes entirely from the larval stage.

5. Female titan beetles are rarely found; most of those discovered are males. This is because females release a substance that attracts males to come and mate, so the females only need to stay where they are and wait.

3. What Harm Do Longhorn Beetles Bring to Plants?

1. Longhorn beetles are phytophagous insects that harm woody plants, herbaceous plants, and also timber, buildings, houses and furniture. They are major pests in forestry production, crop cultivation and construction timber.

2. The larvae and adults of longhorn beetles mostly prefer to be active on trees. Because there are many species, the tree species they damage also differ. Among the trees that suffer more damage, mulberry has 28 species of longhorn beetles, willow and poplar have 25 species, citrus has 18 species, and pine has 23 species.

3. The larvae of longhorn beetles bore into trunks, branches and roots. If they damage woody plants, they weaken the tree's vigor, allow pathogens to invade, and make the tree easily broken by wind; in severe cases the whole plant dies. If they damage herbaceous plants, they cause crop yield reduction, wilting or death.

4. Adult longhorn beetles feed on pollen, tender bark, young shoots, leaves, roots, sap, fruit, fungi and so on. Plants such as pine, cypress, willow, elm, walnut, citrus, apple, peach, tea, cotton, wheat, corn, sorghum, sugarcane and hemp can all be damaged.

5. Based on the habits of longhorn beetles, the working people of China created a set of control methods such as searching for and destroying eggs, hooking and killing larvae, applying pesticide to insect holes, and catching and killing adults. Nowadays, control is mostly carried out by spraying or brushing pesticides such as dichlorvos, phosphamidon, dimethoate, chlorpyrifos, fenitrothion, phoxim, chlorpyrifos-methyl, insecticide net, methomyl, omethoate and fluoroacetamide on tree trunks.

Summary: The titan beetle is one of the largest insects in the world, with a body length reaching up to 16.7 cm. It is very strong and can bite a wooden pencil in half. Longhorn beetles are pests that harm fruit trees, timber and crops, and farmers have no choice but to guard against them.
