Animal India - Rice Hispa

Dicladispa armigera is a species of leaf beetle from Southeast Asia, often known by its common name: the ''rice hispa''. These beetles are a well-known invasive pest and are responsible for significant crop damage across many countries. The male-to-female ratio is between 1:1.26 and 1:1.46. The high reproductive potential and short generation time are significant contributors to the success of this species. These insects are known to cause significant plant damage, targeting crops such as rice, maize, and other grasses. Young plants are more susceptible to damage by the pests. The reduction of rice hispa populations in areas where crops are grown is desirable to increase crop yield. The two primary methods for population control are biological controls which utilize predators of the pest, and chemical controls which utilize insecticides. In some cases, manual controls may be used. The insect pest is a problem, particularly in Bangladesh. Records show that it can infest large areas and cause yield losses of up to 20%.
