Abstract

Rice stem borer is an important pest on rice. Its occurrence and distribution needs to be monitored, for the purpose of its control measure. Recently a very high attack occurred on rice in the island of Java, especially in West Java and Central Java. The technological strategy for controlling borers is triangle action strategy, consisting the implementation of SOP borer control, building borer control unity in the community, and farming a strong national and local government commitment on borer control. The application of SOP for borer control, should base on the new economic threshold recently developed, namely based on pest monitoring using light traps, at 4 days after the first adult flight. Borer control should not based on the old economic threshold because by that time the damages had already occur, and sometimes the yield loss had been substantial.

Abstract

Brown planthopper (BPH) is a global rice pest, widespread in the Palaeartik, Oriental, and Australian regions. This pest had caused high losses of economic value, both as yield losses and as funds, to be used for research in the technological control. Both nymphs and adults of BPH are damaging on rice plants, through an extensive sucking of the cell sap. BPH also transmits viruses, thus increases level of BPH infestation occasionally are accompanied by substantial losses of rice crop by virus diseases resulting in hopperburn. Countries most affected by BPH attacks and had spent high number of funds to control are China, Vietnam, Thailand, Philippines, Malaysia, and Indonesia. BPH attack disrupts the nutrient uptake processes occurring on the roots, whereas the rice roots are not only playing a major role in taking up nutrients and water, but also functioning as sites for biosynthesis of substances that affect physiological activities, such as cytokinins, zeatin, and zeatin riboside. Senescence process of the leaves, transportation and distribution of assimilates, grain flling, and grain yield are closely correlated with the function of root systems of the rice plant. Strategy for BPH control includes assembling durable resistance of rice varieties using the available germplasm, tightening resistant line screening, action program such as simultaneous planting based on triangle strategies, increasing the use of light traps to monitor the populations dynamic and reducing insect populations. Control of brown planthopper using insecticides should consider the latest economic threshold, depending on the price of grain at harvest.
