Xystrocera dispar (mango stem borer) - Sikkim Beetle

Xystrocera dispar, also known as the mango stem borer or "aamko botkira" in Nepali, is an insect that affects mango trees. The adult beetle is about 20-30 mm long with a shiny, metallic body. The larvae bore into the stems and branches of mango trees, causing significant damage.

This boring disrupts the flow of nutrients and water, leading to weakened or dead branches. Infested trees often show signs like wilting leaves and dieback. Managing this pest involves regular monitoring and removing infected parts of the tree to prevent the spread of the larvae.

Batocera rufomaculata (Fig borer) - Sikkim Beetle

Batocera rufomaculata, commonly known as Fig borer, tropical fig borer, mango stem borer, a long-horn beetle originating from Asia, was described by Charles De Geer in 1775. It infests various trees including Ficus carica, Carica papaya, Mangifera indica, and Shorea robusta, posing a threat to fruit tree cultivation, particularly mangoes, by causing yield loss and tree death.

Human activities have spread globally, affecting regions like Israel, Madagascar, and the Virgin Islands. Control efforts face challenges due to its broad host range and susceptibility to parasitic infection by Avetianella batocerae. Effective management strategies focus on monitoring, quarantine, and biological controls to mitigate its impact on agriculture and forestry.

Imantocera penicillata - Sikkim Beetle

 

Imantocera penicillata, also known as "Jungli Kira" in Nepali, is a species of beetle in the Cerambycidae family. It was first described by Hope in 1831, initially under the genus Lamia. This beetle is found in Bangladesh, Bhutan, India, Myanmar, China, Thailand, Laos, Nepal, and Vietnam.

It is recognized for its long antennae and striking appearance. The beetle is typically seen in forested and wooded areas where it can be observed on trees and plants. Its larvae feed on various types of wood, contributing to the natural process of decomposition and nutrient recycling in the ecosystem.

Xystrocera globosa (Monkey-pod Borer) - Sikkim Beetle

Xystrocera globosa, also known as the monkey-pod borer or "imli ko kira" in Nepali, is a species of beetle in the family Cerambycidae. It was first described by the French entomologist Guillaume-Antoine Olivier in 1795. This beetle is widely distributed across tropical Asia and infests monkey-pod trees (Samanea saman) and other leguminous trees.

The adult beetle is around 25-30 mm long, with a shiny, metallic greenish-blue body. The larvae bore into the stems and branches of the trees, causing significant damage by disrupting the flow of nutrients and water, which leads to weakened or dead branches.

Trees infested with this borer often show symptoms like wilting leaves and dieback. Effective management involves regular monitoring and removing infected parts to prevent the spread of the larvae.

Leopard Spot Longhorn Beetle (Coptops leucostictica) - Sikkim Beetle

Coptops leucostictica, commonly known as the Leopard Spot Longhorn Beetle or "Chhewar ko kira" in Nepali, is a species of beetle in the Cerambycidae family. First described by White in 1858, this beetle is found in India, Cambodia, Thailand, Laos, China, Myanmar, Malaysia, and Vietnam.

It has a distinctive appearance with leopard-like spots on its body. The beetle larvae feed on the Albizia julibrissin tree, also known as the silk tree or mimosa. The feeding habits of the larvae can damage the tree, leading to weakened branches and reduced health of the plant.
