Experimentation with ecological engineering in china indicated that it offers immense opportunities to rice pest management using non-chemical methods leading to economic and environmental benefits. Ecological engineering is not a 'high-tech' approach so is simple and practical for rice farmers to implement.
High population of planthoppers cause leaves to initially turn orange-yellow before becoming brown and dry and this is a condition called hopperburn that kills the plant. Bph can also transmit rice ragged stunt and rice grassy stunt diseases.

Biological, coupled with cultural control such as the use of resistant varieties and proper crop management practices, is the most ideal planthopper management strategy. Cultural control • use varieties that are resistant to planthoppers. • grow early maturing varieties to have a rice-free period of more than 1 month to break pest cycle.

The brown planthopper (bph) is an insect pest of rice in terai. Bph is a small brown insect found mainly on the base of rice plants above the water level. Adults and young suck the plant sap from leaf sheathes, causing yellowing of lower and then upper leaves. Whole areas can die in patches which are said to be affected by “hopper burn”.
Focused on two widespread rice pests: the striped stem borer caterpillar and the brown planthopper. Rice can make different blends of odors to attract animals that rid the plant of feeding herbivores. One such animal is a species of wasp called anagrus nilaparvatae, which lays its eggs inside planthopper eggs.

Flowering plants as refuge can contribute in enhancing the ecosystem services. This study aimed to assess the benefit of flowering plants as refuge to improve the role of egg parasitoids of brown planthopper. We sampled three rice fields: rice field adjacent to refuge, far from refuge, and rice field with no refuge using trapping procedure.
Planthoppers and leafhoppers are serious insect pests of rice. They damage the plants directly by sucking the plant sap, resulting in complete drying of the plants, which is called hopperburn. They also damage the plants indirectly by serving as vectors for the transmission of several virus diseases of rice.
Bph, nilaparvata lugens (stål)) and the white-backed planthopper (abr. Wbph, sogatella furcifera (horváth)) have been recorded as important pests of rice in taiwan since 1912 (nitobe, 1912).
