Abstract In May 1977, a symposium was held at the International Rice Research Institute in the Philippines to discuss the results of research on Nilaparvata lugens (Stal) on rice and to develop plans for its control. The second putative source is the Philippines where rice is also the main food crop. Apparently, 70% of 21000 insects in the Philippines are endemic. The brown planthopper have developed high resistance to imidacloprid, a member of neonicotinoid insecticides. The brown planthopper (BPH) Nilaparvata lugens (Stal) is a serious pest of rice in Asia. [27], "Green revolution: preparing for the 21st century", "Brown plant hopper (BPH) | Rice Knowledge Management Portal - Rice,Paddy,Dhan,Chawal,Rice Research Domain, Rice Extension Domain, Rice Farmers Domain ,Rice General Domain, Rice Service Domain,RKMP,Rice in India,Rice Government Schemes, Rice ITKs, Rice FLDs, Rice Package of Practices". Correspondence analysis was applied to different groups of descriptors: farmers' socio-economic background, perceptions, and aclions to control pests in their past farming experience. Photo 3. It infests and kills the rice plants at all stage of plant growth by feeding intensively on them and also transmits grassy stunt and ragged stunt virus diseases (Reissig et al. Observe the 20 cm x 20 cm planting distance. R. C. Saxena and L. M. Rueda, Morphological variations among three biotypes of the brown planthopper Nilaparvata lugens in the Philippines, International Journal … " Morphological variations among three brown planthopper biotypes in the Philippines " Save as: AGRIS_AP RIS EndNote(XML) Many novel genes for these functions have been detected in tissue from BPH intestines. Brown plant-hopper in rice and its control. Indian Farming, 27(5):3-5. When these insects target a rice plant the plant loses its golden glow and turns brown before dying. To date, more than 24 major BPH-resistance genes have been reported in several Oryza sativa ssp. It lives in temperate and tropical zones of Asia. Allozyme variation among biotypes of the brown planthopperNilaparvata lugens in the Philippines Philippines, together with data obtained from the literature. 1990. Increasing nitrogen levels, closer plant spacing, and higher alternative humidity increase their numbers. International Rice Research Newsletter 15(4): 27-28. indica cultivars and wild relatives. The brown planthopper (Nilaparvata lugens [Stål]) ... Srinivasan et al. Development of novel control strategies can be facilitated by comparison of BPH feeding behaviour on varieties exhibiting natural genetic variation, and then elucidation of the underlying mechanisms of resistance. The initial purpose is to simulate observed population changes, in order to understand the essential factors controlling the population dynamics of this pest. The brown planthopper,Nilaparvata lugens (Stål), and some related species: A biotaxonomic approach. Nitrogen fertilizer, high tillering varieties and/or close spacing and good water management are factors that contribute to a population increase. They pass through five instars before becoming adults. Adults usually mate on the day of emergence, and the females start laying eggs from the day following mating. Los Baños, Laguna, Philippines. The brown planthopper (BPH), Nilaparvata lugens (Stål), is one of the most serious and destructive pests of rice, and can be found throughout the rice-growing areas of Asia. [4] In some cases, BPHs lay eggs in the rice seed beds (also known as rice nurseries) shortly before transplanting, so enter the field in this manner. Dragonflies and damselflies prey on moving adults. These insects are among the most important pests of rice, which is the major staple crop for about half the world's population. Taxonomy and bionomics of the insect parasites of rice leafhoppers and planthoppers in the Philippines and their importance in natural biological control. [23][24][25][26] use resistant variety laal, Research indicates that BPH nymphs are already living at the upper limits of tolerable temperatures. Sogawa, K. , & Cheng, C. H. (1979). Khush, G. S. (1979). Light-trap data showed that peak numbers of the pest were present 7-9 weeks after transplanting. The bodies of these butterflies are really well-coloured in dark red to brown and velvety black or gray with a black stripe pattern. The third putative source is Myanmar and Bangladesh, but … Life cycle: Eggs are laid in batches inside the leaf sheaths and on the leaf midrib. Asian Rice Farming and Food Security: Fixing Insecticide Misuse. The macropterous forms are potentially migrants and are responsible for colonizing new fields. In addition, the Philippines and other east Asian populations of . In Brown Planthopper: Threat to Rice Production in Asia, pp. What it does High population of planthoppers cause leaves to initially turn orange-yellow before becoming brown and dry … Adaptation of the brown planthopper, Nilaparvata lugens (Stål), to resistant rice varieties Jedeliza B. Ferrater . (1979) Breeding for resistance to brown planthopper and grassy stunt virus in Indonesia. International Rice Research Newsletter 15(6): 25. ., 2008). Foodweb of the rice brown planthopper in the Philippines. IR64, are important for preventing outbreaks. Damages in most cases were in the later crop stages, although in Candon, Ilocos Sur, damages were observed at maximum tillering. Similarly, spiders, water bugs, and lady beetles prey on mobile stages (nymphs and adults). (1) A simulation model of brown planthopper (Nilaparvata lugens Stal.) 20 days before transplanting. Adults with long wings are attracted to light traps. 1. Summary. The eggs are highly sensitive to desiccation and soon shrivel when the host plant starts wilting. International Rice Research Newsletter, 1(2):14. [15], Rice varieties with resistance to BPH, e.g. In Brown Planthopper: Threat to Rice Production in Asia, pp. Seek the advice of a crop protection specialist for guidance before applying insecticides. The standard seedbox screening tests (SSST) were modified to identify field-resistant varieties in the greenhouse. They feed on plant sap. * The International Rice Research Institute, Manila, the Philippines. Proceedings of the Symposium at the International Rice Research Institute, April 1977. 1979 pp. Kuno, E. (1979) Ecology of the brown planthopper in temperate regions. The brown planthopper is dimorphic, with fully winged 'macropterous' and truncate-winged 'brachypterous' forms. For example in 2011, the Thai government announced an initiative to respond to a major brown planthoppers outbreak by restricting outbreak-causing insecticides including abamectin and cypermethrin; the decision was supported by the International Rice Research Institute (IRRI). [7][8] Some insecticides increase the amount of amino acids and sucrose available in the phloem of rice plants, and thereby increase BPH survival. After settling on rice plants, they produce the next generation, where most of the female insects develop as brachypters and males as macropters. Photo 2. In Brown Planthopper: Threat to Rice Production in Asia, pp. Insecticides kill their predators and the parasitoids. Do not spray 30 days after transplanting or 40 days after seeding. Brown planthopper: threat to rice production in Asia. They transmit five virus diseases and can cause massive damages. in Keycheck7 Pest Management. Rice brown planthopper (064) Search. Uniquely, the research proved that this butterfly is very difficult to kill. 19–32. Broader term(s) : Arachnida arachnida Subject Category: Organism Names Genetics of and breeding for resistance to the brown planthopper. Apply insecticide as a last resort and its benefits should be weighed against the risk. rice varieties (Sogawa 1992). Heavy infestation creates brown patches of dried plants known as hopperburn. 126 . We found that brown planthopper populations collected in the Philippines between 2009 and 2010 were relatively susceptible to the tested insecticides when compared to historical data. Los Banos, Philippines, Int. During the early infestation stage, round yellow patches appear, which soon become brownish due to the drying up of the plants. International Rice Research Conference, 22-24 April 1974, LosBanos, Laguna, Philippines, 16p. Plow under volunteer rations after harvest. The brown planthopper is dimorphic, with fully winged 'macropterous' and truncate-winged 'brachypterous' forms. Identifying marks: Adults are 2.5-3.0 mm long, winged, or without wings. This suggests that climate warming in tropical regions with occasional extremely high temperatures would limit the survival and distribution of BPH. The brown planthopper have developed high resistance to imidacloprid, a member of neonicotinoid insecticides. 31.94; Alberto T. Barrion. Introduction. International Rice Research Institute: Brown planthopper: threat to rice production in Asia. Up to 60% yield loss is common in susceptible rice cultivars attacked by the insect. [16][17][18] However, in areas with low insecticide use, high levels of BPH resistance are not usually necessary. [9], Excessive use of urea as nitrogenous fertilizer and insecticides can lead to outbreaks by increasing the fecundity of the brown planthopper, and by reducing populations of natural enemies. [14] In December 2011, the IRRI held a conference in Vietnam to address the threats of insecticide misuse and explore options for mitigation. Spraying prevents the early season movement and colonization of beneficial organisms. Brown mirid bug, a new predator of brown planthopper in the Philippines. A Case Study with the Brown Planthopper Nilaparvata lugens (Stål)", Ricehoppers – a blog on the latest information and issues relevant to managing rice planthopper problems, https://en.wikipedia.org/w/index.php?title=Brown_planthopper&oldid=982257863, Articles with unsourced statements from June 2020, Creative Commons Attribution-ShareAlike License, This page was last edited on 7 October 2020, at 01:50. [1] They damage rice directly through feeding and also by transmitting two viruses, rice ragged stunt virus and rice grassy stunt virus. These BPHs were then transferred to a mature TN1 rice clone and kept in net cages in an insect growth facility with similar conditions to above. Avoid early application of pesticides or establish refuge areas to encourage buildup of useful organisms. IRRN 1990 15 (6) 25Manti, I. and Shepard, B.M. Are you satisfied with PINOYRICE KNOWLEDGE BANK? 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. The Brown Planthopper (BPH) Nilaparvata lugens (Stål) has become a number one threat to tropical rice production in many parts of Asia in the last three decades (Dale, 1994). 209---218. International Rice Research Institute, Los Banos, Philippines. This occurs when large numbers of insects suck the sap from plants and cause then to wilt and die. 128 . Morphological variations among three biotypes of the brown planthopper Nilaparvata lugens in the Philippines [pest of rice]. The inbred varieties were generally said to have moderate to intermediate resistance brown planthopper (BPH). Population dynamics of the brown planthopper (BPH), Nilaparvata lugens Stål, were investigated in paddy fields in the coastal lowland of West Java, Indonesia, where rice is cultivated twice a year, in the wet and dry cropping seasons.

[13] IRRI also outlined recommendations in an action plan to help smartly manage planthopper outbreaks. 201 – 208. International Rice Research Institute, Los Baños, Laguna, Philippines. Increased potassium reduces planthopper susceptibility as cell walls get thicker because of greater silica uptake. Los Banos, Laguna, Philippines: The International Rice Research Institute. Use appropriate and balanced fertilization. We find support for immigration from the … The Philippines, once considered a key source, is not significant, with little evidence for their migration into China. The initial purpose is to simulate observed population changes, in order to understand the essential factors controlling the population dynamics of this pest. Kalode MB, 1976.
