Foodweb of the rice brown planthopper in the Philippines. The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) is a planthopper species that feeds on rice plants (Oryza sativa L.). The brown planthopper (Nilaparvata lugens [Stål]) ... Srinivasan et al. The initial purpose is to simulate observed population changes, in order to understand the essential factors controlling the population dynamics of this pest. R. C. Saxena and L. M. Rueda, Morphological variations among three biotypes of the brown planthopper Nilaparvata lugens in the Philippines, International Journal … In Brown Planthopper: Threat to Rice Production in Asia, pp. Cultural Management Within the Philippines, brown planthopper outbreaks were observed in IR26 after 2 to 3 years of commercial cultivation (approximately 6 crops) as the result of a selection of a strain that could feed on IR26 (biotype 2). 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. Los Baños, Laguna, Philippines. 201 – 208. International Rice Research Institute, Los Baños, Laguna, Philippines. Dense planting increases number of planthoppers. Using Manly's preference index, α, both the male and female C. lividipennis were found to prefer BPH eggs. Large numbers of the brown planthopper, Nilaparvata lugens, at the base of rice plants at water level. 19–32. Adults usually mate on the day of emergence, and the females start laying eggs from the day following mating. The brown planthopper (Nilaparvata lugens) damages and kills rice plants. It is rare in upland rice conditions. Plant early-maturing varieties to create a rice-free period during the year. These insects are among the most important pests of rice, which is the major staple crop for about half the world's population. They pass through five instars before becoming adults. [21], In an attempt to make BPH control more species-specific, researchers are trying to develop methods of turning off specific BPH genes for digestion-, defense- and xenobiotic metabolism. During the early infestation stage, round yellow patches appear, which soon become brownish due to the drying up of the plants. 1991 Apr;29(3-4):115-23. In Proceedings, 2nd International Workshop on Leafhoppers and Planthoppers of Economic Importance, Provo, Utah, 1986, pp. Today, three major species of rice planthoppers (brown planthopper, whitebacked planthopper, and small brown planthopper) have been reported as a menace in Bangladesh, Cambodia, China, India, Indonesia, Japan, Korea, Laos, Malaysia, the Philippines, Thailand, and Vietnam. [22], Some plant lectins are antifeedants to BPH and if properly formulated may have the potential to protect rice from BPH. Taxonomy and bionomics of the insect parasites of rice leafhoppers and planthoppers in the Philippines and their importance in natural biological control. Identifying marks: Adults are 2.5-3.0 mm long, winged, or without wings. Honeydew clock. [16][17][18] However, in areas with low insecticide use, high levels of BPH resistance are not usually necessary. Damage: Adults and nymphs cause direct damage by sucking the sap at the base of the tillers. Asian Rice Farming and Food Security: Fixing Insecticide Misuse. 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. Brown planthopper: threat to rice production in Asia. The newly hatched nymphs are cottony white, and turn purple brown within an hour. Inst. The brown planthopper disperses and colonizes rice fields in relatively calm weather conditions (Ohkubo and Kisimoto, 1971; Ohkubo, 1973; MacQuillan, 1975). The brown planthopper The brown planthopper is an insect pest of rice (Oryza sativa). [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". The brown planthopper The brown planthopper is an insect pest of rice (Oryza sativa). Background: The brown planthopper, Nilaparvata lugens (Stål), is one of the most notorious pests of rice throughout Asia. The brown planthopper is dimorphic, with fully winged 'macropterous' and truncate-winged 'brachypterous' forms. Allozyme variation among biotypes of the brown planthopperNilaparvata lugens in the Philippines When these insects target a rice plant the plant loses its golden glow and turns brown before dying. Identifier(s) : brown planthopper, choice, paddy, pest arthropods, pest insects, rice brown planthopper, spiders Geographical Location(s) : Philippines philippines Subject Category: Geographic Entities see more details. Dragonflies and damselflies prey on moving adults. Introduction. In one, 7‐day‐old seedlings were infested with insects and then classified on the basis of insect injury. [19] Chemical mutagenesis can significantly increase or decrease BPH resistance levels of rice. The rice brown planthopper (BHP) usually exists in two forms at the height of an outbreak, namely the long-winged form or macropterous form and the short-winged or brachypterous form. Here the farmers were using high nitrogen … Tagalog names: kayumangging hanip, kayumangging ngusong kabayo. IR64, are important for preventing outbreaks. Khush G. S. (1979) Genetics and breeding for resistance to the brown planthopper. 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. The flight capabilities of laboratory and tropical field populations of the brown planthopper, Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) - Volume 70 Issue 4 - … High nitrogen use increases planthopper attack. The rice brown planthopper Nilaparvata lugens Stal in Karnataka, India. Tagalog names: kayumangging hanip, kayumangging ngusong kabayo. Are you satisfied with PINOYRICE KNOWLEDGE BANK? 1979 pp. Plants can recover from early damages by producing new leaves and tillers. ., 2008). Due to feeding by both the nymphs and adults at the base of the tillers, plants turn yellow and dry up rapidly. The functional response of Cyrtorhinus lividipennis feeding on brown planthopper (BPH) and green leafhopper (GLH) eggs was found to be Holling's Type II. Damages in most cases were in the later crop stages, although in Candon, Ilocos Sur, damages were observed at maximum tillering. Nymphs molt five times before turning to adult. Use appropriate and balanced fertilization. Host resistance has been found to be the most suitable alternative to manage the insect. Authors R C Saxena 1 , C G Demayo, A A Barrion. Predation of brown planthopper eggs by Cyrtorhinus lividipennis Reuter. Our findings provide baseline data for future studies. Nitrogen fertilizer, high tillering varieties and/or close spacing and good water management are factors that contribute to a population increase. These insects are among the most important pests of rice, which is the major staple crop for about half the world's population. Brown Planthopper. Several genes and mutations conferring imidacloprid resistance in N. lugens, especially in eastern and southeastern Asia populations, have been reported. During field insecticide tests on rice in Sultan Kudarat Province, Philippines, up to 5% of the hills in some nearly ripe plots of IR36 were damaged by the brown planthopper [Nilaparvata lugens (Stal)], even though this variety is resistant rated as to this pest. 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). 125–142). Brown mirid bug, a new predator of brown planthopper in the Philippines. Adaptation of the brown planthopper, Nilaparvata lugens (Stål), to resistant rice varieties 200 pages PhD thesis, Wageningen University, Wageningen, NL (2015) With references, with summary in English ISBN 978-94-6257-559-2. January 1981; Authors: James A. Litsinger. [14] In December 2011, the IRRI held a conference in Vietnam to address the threats of insecticide misuse and explore options for mitigation. 127 . Keep water level low enhances growth of useful organisms. Harahap, Z. They transmit five virus diseases and can cause massive damages. What it does. 45 – 60. The hatchability and survival rate are the highest around 25 °C. At this stage, BPH population tend to build up rapidly. Correspondence analysis was applied to different groups of descriptors: farmers' socio-economic background, perceptions, and aclions to control pests in their past farming experience. [Google Scholar] Grow only two rice crops per year and use early-maturing varieties to reduce their continuous breeding. Planthoppers are not pests until you indiscriminately apply insecticides. Adults with long wings are attracted to light traps. Similarly, spiders, water bugs, and lady beetles prey on mobile stages (nymphs and adults). BPH[3] infest the rice crop at all stages of plant growth. Development of field resistance among Asian brown planthopper populations to insecticides contributes significantly towards the overall problem caused by the brown planthopper in rice production. Uniquely, the research proved that this butterfly is very difficult to kill. The iesults were inter- preted using a modified version of Mumford and Norton (1984) behavioral model. 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. 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. They also transmit viral diseases: ragged stunt, grassy stunt and wilted stunt. International Rice Research Institute, Los Banos, Laguna, Philippines. 7. Increased potassium reduces planthopper susceptibility as cell walls get thicker because of greater silica uptake. ChannaBasavanna GP, Gubbaiah G, Rai PS, Mahadevappa M, 1976. 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. Weather simulations indicate that brown plan- After settling on rice plants, they produce the next generation, where most of the female insects develop as brachypters and males as macropters. The third putative source is Myanmar and Bangladesh, but … What it does High population of planthoppers cause leaves to initially turn orange-yellow before becoming brown and dry … The brown planthopper (Nilaparvata lugens [Stål]) is regarded as one of the most damaging pests of rice (Oryza sativa L.) in Asia (Bottrell and Schoenly, 2012).The planthopper, a phloem feeder, is largely monophagous on rice (Sogawa, 1982).For several decades, host plant resistance has been the main focus of public research to combat the planthopper (Brar et al., 2009, … International Rice Research Newsletter 15(6): 25. Many novel genes for these functions have been detected in tissue from BPH intestines. Hopperburn caused by the brown planthopper, Nilaparvata lugens. The Dome Planthopper. All plant growth stages are attacked, but the most susceptible growth stages are from early tillering to flowering. Use selective insecticide if level of pest infestation is very high to spare beneficial organisms. Previous post: Management options for common rice diseases. 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. The eggs are thrust in a straight line generally along the mid-region of the leaf sheath. (1) A simulation model of brown planthopper (Nilaparvata lugens Stal.) Summary. It lives in temperate and tropical zones of Asia. 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). Khush, G. S. (1979). These are the brown planthopper (BPH), Nilaparvata lugens (Stal); and the whitebacked planthopper (WBPH), Sogatella furcifera (Horvath). It is rare in upland rice conditions. Seedbed areas must be as far as possible from light sources to discourage hopper attack and virus infection by virus-infected hoppers. Photo 1. Brown plant-hopper in rice and its control. Allozyme variation in local populations of the brown planthopper Nilaparvata lugens (Stål) in the Philippines. The initial purpose is to simulate observed population changes, in order to understand the essential factors controlling the population dynamics of this pest. Brown planthopper: threat to rice production in Asia. Increasing nitrogen levels, closer plant spacing, and higher alternative humidity increase their numbers. Split nitrogen into three applications during crop growth to reduce BPH buildup. * The International Rice Research Institute, Manila, the Philippines. 209---218. International Rice Research Institute, Los Banos, Philippines. indica cultivars and wild relatives. In Brown Planthopper: Threat to Rice Production in Asia, pp. This suggests that climate warming in tropical regions with occasional extremely high temperatures would limit the survival and distribution of BPH. Practiced synchronous planting after a fallow period, Management options for common rice diseases. International Rice Research Newsletter 15(4): 27-28. 128 . The brown planthopper (BPH) is a potent pest of rice in Asia and Southeast Asia. The brown planthopper have developed high resistance to imidacloprid, a member of neonicotinoid insecticides. The increase in severity of the insect appears to be associated with the technology used in modern rice culture. Addressing Planthopper Threats to . Broader term(s) : Arachnida arachnida Subject Category: Organism Names 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. We evaluated the susceptibility of brown planthoppers collected in the Philippines to the insecticides imidacloprid, fipronil and fenobucarb insecticides. Brown planthopper (BPH) biotype 2 cultures were obtained in July 2008 from MARDI research station at Pulau Pinang, Malaysia. [6] Some insecticides evidently increase the protein content of BPH male accessory glands, and thereby increase planthopper fecundity. Los Banos, Laguna, Philippines: The International Rice Research Institute. Allozyme variation among biotypes of the brown planthopper Nilaparvata lugens in the Philippines Biochem Genet. 31.94; Alberto T. Barrion. Only brachypterous adult females were selected for experiments. Heavy infestation creates brown patches of dried plants known as hopperburn. In addition, the Philippines and other east Asian populations of . Morphological variations among three biotypes of the brown planthopper Nilaparvata lugens in the Philippines [pest of rice]. Studies of varietal resistance in rice to the brown planthopper at the International Rice Research Institute.—pp. 285–301 in Brown planthopper: threat to rice production in Asia.— 369 pp. Kalode MB, 1976. Printed in the Philippines ADB Sustainable Development Working Paper Series Printed on recycled paper. [23][24][25][26] use resistant variety laal, Research indicates that BPH nymphs are already living at the upper limits of tolerable temperatures. "Factors Affecting Insecticide-Induced Resurgence of the Brown Planthopper, 10.2135/cropsci1971.0011183X001100050043x, "Proteome Analysis of Rice (Oryza sativa L.)

The eggs are highly sensitive to desiccation and soon shrivel when the host plant starts wilting. [7][8] Some insecticides increase the amount of amino acids and sucrose available in the phloem of rice plants, and thereby increase BPH survival. … Photo 2. (2015) indicated that planthopper populations in the Philippines have progressively overcome BPH25 and BPH26 resistance apparently without either gene ever being widely deployed. Raise the level of irrigation water periodically to drown the eggs, which are deposited at the base of the tillers and in leaf sheaths. Plow under volunteer rations after harvest. Philippine Entomologist, 4(3):119-139 . The inbred varieties were generally said to have moderate to intermediate resistance brown planthopper (BPH). Philippines, together with data obtained from the literature. The legs are hairless and the hind leg has a large, mobile outgrowth. We therefore sequenced the genomes of brown planthopper populations from across temperate and tropical parts of their distribution and show that the Indochinese peninsula is the major source of migration into temperate China. seasonal monsoon suggest that brown planthopper populations in the Mekong River Delta cannot migrate into the Red River Delta and then to China because the seasonal winds in February to April are not suitable (Hu, Lu, Tuan, & Liu, 2017; Zhai & Cheng, 2006). Background: The brown planthopper, Nilaparvata lugens (Stål), is one of the most notorious pests of rice throughout Asia. Light-trap data showed that peak numbers of the pest were present 7-9 weeks after transplanting. Eggs hatch in about six to nine days. Identifying marks: Adults are 2.5-3.0 mm long, winged, or without wings. In Brown Planthopper: Threat to Rice Production in Asia, pp. Philippines, together with data obtained from the literature. The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) is a planthopper species that feeds on rice plants (Oryza sativa L.). Kong Luen Heong with Larry Wong and Joy Hasmin De los Reyes No. Excreted honeydew on infested plants may also become a medium for sooty mold fungus. Plants turn yellow and dry up rapidly. BPH population growth is maximal in a temperature range from 28 to 30 °C[citation needed]. January 1981; Authors: James A. Litsinger. Change in the abundance of adults of the brown planthopper and green leafhoppers as shown in light trap catches (IRRI, 1967-1971). The BPH is distributed throughout Australia, Bangladesh, Bhutan, Burma (Myanmar), Cambodia, China, Fiji, India,[2] Indonesia, Japan, North and South Korea, Laos, Malaysia, India, Nepal, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand, and Vietnam. The macropterous forms are potentially migrants and are responsible for colonizing new fields. Brachypterous females lay 300 to 350 eggs, whereas macropterous females lay fewer eggs. Rice brown planthopper (064) Search. International Rice Research Conference, 22-24 April 1974, LosBanos, Laguna, Philippines, 16p. 1990. 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. The brown planthopper is dimorphic, with fully winged 'macropterous' and truncate-winged 'brachypterous' forms. 31.94; Alberto T. Barrion. These are the brown planthopper (BPH), Nilaparvata lugens (Stal); and the whitebacked planthopper (WBPH), Sogatella furcifera (Horvath). [20] Some chemical insecticides, e.g. The Philippines, once considered a key source, is not significant, with little evidence for their migration into China. Direct-sown fields are more prone to heavy damage than transplanted fields. The brown planthopper (BPH) Nilaparvata lugens (Stal) is a serious pest of rice in Asia. Insecticides kill their predators and the parasitoids. [1] They damage rice directly through feeding and also by transmitting two viruses, rice ragged stunt virus and rice grassy stunt virus.
