Bamboo Weevil Borer –
Cyrtotrachelus longimanus
There are some 18 weevil species attacking bamboo shoots. Both adults and larvae of these weevils feed on shoots, although larvae, which bore holes on bamboo shoots, are responsible for most of the damage. The damage caused by weevils usually results in the death of very young shoots, or deformed and stunted growth of new culms with very closely formed nodes at the feeding site. The larger species are the most common and destructive on sympodial bamboos.
Cyrtotrachelus longimanus is one of the most destructive insects attacking bamboo.
The larvae of this weevil tunnel and feed in the young shoots; these fall to the ground at the time when the beetles are ready to enter the soil for pupation, involving the loss of the whole shoot.
DISTRIBUTION
Bangladesh, China, India, Myanmar and Sri Lanka.
HOSTS
Lingnania chungii, Bambusa textilis, B. pervariabilis, Sinocalamus oldhami, Dendrocalamus strictus, D. hamiltonii, Melocanna baccifera
and some other bamboos.
BIOLOGY
Adults are 18-38 mm long and vary in colour from light brown to dark reddish-brown. The legless larvae are cream-white in colour, but turn light brown when they are fully fed. There is only one generation per year, overwintering as adult in cocoons in the soil. Adults and larvae can be found on bamboo shoots from May to early October. The overwintering adults emerge from the soil during spring and summer months when bamboo shoots are available. They feed by sucking sap from the upper part of shoots. Eggs are laid individually in large feeding holes and only 1-3 eggs are deposited on each shoot. The egg-laying site can be identified by a group of fibre sticking out of the shoot surface. The larvae feed and bore inside the bamboo shoots, forming vertical tunnels. They pass through five instars in 12-15 days. Fully fed larvae drop to the ground, burrow into the soil and pupate 2-3 weeks later in cocoons made with soil at 10-30 cm depth. Adults emerge within 15 days after pupation.
They often occur together, is usually found on bamboo species with culms smaller than 4 cm in diameter.
DAMAGE CAUSED
These weevils are important borers of young sprouting culms. Damage is characterized by a long larval tunnel, starting beneath or near the culm sheath, passing internally through several internodes with perforation of nodes and ending in a hollowed and dead terminal shoot. These tunnels are filled with wooden dust and excreta. Wind, rain, feeding by woodpeckers, etc. can cause the affected culms to readily break. A single larva is capable of destroying a culm and inducing development of multiple shoots of little commercial value.
