Corresponds to a report on the basis of at least one observation proved within a period of 10 years 20 years for little-known invertebrates preceding the year and no presumption of extinction since obtaining the last data nor doubt on reproductive and implemented nature of this population. For migratory species, the presence indicated concerns areas of reproduction.

The adult beetles burrow into felled culms through wounds, cracks and cut ends, and make horizontal tunnels along the fibrovascular tissues of the culms; the larvae make longitudinal tunnels.

The damaged part of the culm becomes powdery, and the powder is sifted from the beetle hole. Large populations of borers will leave numerous tunnels in the culm, making it useless. Also a great quantity of beetle holes will be left on the surface of the culms.

The damaging habits of D. There are several options for the control of D. Selecting the best option depends on a number of factors, such as the severity of infestation, the location of infestation, potential for reinfestation, and cost of treatment Plank, ; Xu Tiansen, ; Kumar et al.

Phytosanitary Measures D. Therefore in many open ports, D. All imported wood, containers and products are treated by government pest control operators using fumigation and heating, for example, if some symptoms of defoliation are detected Xu Changtang, Biological Control There are a few predators reported that can be used to control D. Spathius bisignatus [Platyspathius dinoderi] and Spathius vulnificus parasitize the eggs of D.

Tillus notatus preys on the larvae, pupae and adults. These natural enemies cannot be relied upon as an effective control method, although they can cause high mortality of the borers. To date , no literature concerning successful examples of biological control methods for the control of D.

Physical Control After felling, the physical or chemical treatment of culms can significantly improve their resistance to borers as well as to fungi.

The traditional and simplest method is to immerse felled culms in water. This method may only be effective in preventing damage from bostrychid beetles. It is also only suitable for those bamboos with a low starch content. This method takes a long time and culms treated in this way tend to blacken Xu Tiansen, The heating of culms using fire, boiling water or exposure to direct sunlight in hot summers, can kill borers of D.

Some advanced microwave and infrared techniques have recently been developed for killing the borers in bamboo culms Yao Kang et al. Chemical Control Due to the variable regulations around de- registration of pesticides, we are for the moment not including any specific chemical control recommendations.

Insects that cause damage to felled culm and finished products are probably the most common and serious pests in the Asian bamboo industry. Over 50 such insect species have been reported, and ghoon borers Dinoderus spp. Damages usually result in the loss of large amounts of raw materials or in the destruction of finished bamboo products. Bamboo under storage, either as culms or as finished products, is very susceptible to damage by insects.

Occasionally, subterranean termites cause severe damage. However, the most important pest of bamboo under storage conditions is the ghoon borer, D. Large quantities of culms are destroyed each year by insect borers, although the extent of loss has not yet been assessed.

In storage yards, stacks with immature culms are the starting points for attack and the bamboo is often converted to dust. Mathew and Nair reported that finished products made of reed or bamboo, such as mats, baskets, curtains, etc. Cookies on Plantwise Knowledge Bank. Close Find out more. Species Page. On this page:.
