BPH
is a common designation for liquids plant-sucking insects of the order
Hemiptera (true ladybugs), suborder Fulgoromorpha, especially small
ones. Cicadas been classified as leafhoppers (below suborder Auchenorrhyncha) but now has separated taxonomically. Because of the exclusive live plants, a number of members to be important pests in crops. In
addition to the direct eater, leafhoppers also be a vector for the
transmission of some important plant diseases, especially of the virus
group.Leafhoppers important example:green leafhopper (Nephotettix spp.), a major pest of rice for tungro virus spreader. The virus that causes this disease is badnavirus Rice tungro bacilliform (RTBV) and Rice tungro spherical badna virus (RTSV). Tungro disease can cause substantial yield loss in rice production.
Brown planthopper (Nilaparvata lugens)Brown
planthopper rod (WBC) is one of the important pests in rice crops
because it can cause damage either directly or indirectly. Direct
damage occurred because these pests have the ability to suck sap that
causes leaf yellowing, dried and finally died with symptoms hopperburn
known. Damage occurs indirectly as these insects are vectors of disease stunted grass and dwarf empty. Chocolate
bar hopper is an important pest of rice crops in Indonesia, which since
1985 has threatened the rice self-sufficiency target. The
main factors contributing to the increasing population and the brown
plant hopper attacks stem in recent years is the biotic potential of the
brown planthopper rod high, abiotic factors and rice cultivation
systems that support the development of stem brown planthopper
populations. Predators to control leafhoppers are Cyrtorhinus lividipennis (Reuter) (Hemiptera: Miridae).
White back planthopper (Sogatella furcifera)Leafhoppers
as pest is difficult to control because it has various biotypes that
each has its own preferences for different cultivars as well.
