brown planthopper bph

Number of the larvae bored into the rice stems were counted after 24 h of inoculation, S.K. Be careful of the outbreak of Brown planthopper (BPH) due to drought. Background: Brown planthopper (BPH) is the most destructive insect in rice production. Although the insect is endemic in the tropics where The brown planthopper (BPH), Nilaparvata lugens Stål, is a major rice pest in many parts of Asia. (1985) indicated for the first time that the trait for non-waxiness was controlled by a recessive gene. Scientific name Two species of planthopper infest rice. Abigail M. Hayes, ... Laura Corley Lavine, in Advances in Insect Physiology, 2019. Therefore, breeding hybrid rice resistant to BPH is the most effective and economical strategy to maintain high and stable production. The QTL regions were very long and the desirable genes may have been lost due to recombination during backcrossing. Angadi et al. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Nguyen Cong Thuat, Dias van Thans, 1984. What is the abbreviation for Brown Planthopper? Although the vast majority of species of Auchenorrhyncha are benign, the group contains some of the most destructive pests of agriculture. Michael J. Stout, in Integrated Pest Management, 2014. In this study, HPLC, MS/MS, and … Host plant resistance is an effective, economic and environmentally friendly approach to control crop pests. Outbreak frequency of Nilaparvata lugens (brown planthopper; BPH) has been increasing in Asian rice growing countries in recent years (2005–2012) .These trends are widely linked to adverse effects on BPH … Aspergillus luchuensis and a diversity of other fungi are parasitized in India by Fusarium udum (Upadhyay et al. Wang et al. duration and lower fecundity in brown planthopper (BPH) fed on Bt rice line KMD2, although Bt insecticidal protein Cry1Ab could rarely concentrate in this non-target rice pest. These are the brown planthopper (BPH), Nilaparvata lugens (Stal); and the whitebacked planthopper (WBH), Sogatella furcifera (Horvath). When the stem was extracted with water, the number of larvae that moved to the extract from the stem was smaller in the stem containing a higher Si. 1981), which produces a diffusible toxin and induces vesicular deformations in its host. What are the genes for phenotypic plasticity and are they conserved? In addition, nAChR mutation may partly be associated with reduced IMI mortality and receptor sensitivity, involving Tyr to Ser (adjacent to loop B Trp) of α subunit in Nilaparvata or Arg to Thr (neighbouring loop D Trp) of β subunit in Myzus (Bass et al., 2011; Liu et al., 2005). is a pest of rice in Asia; damage is caused by direct feeding and by the transmission of rice ragged stunt and rice grassy stunt diseases. However, little is known about the mechanisms responsible for the development, wing dimorphism and sex difference in this species. He found that most larvae moved to the stem with low Si content. 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. Whole areas can die in patches which are said to be affected by “hopper burn”. By continuing you agree to the use of cookies. Gallun and Khush (1980) reported the effectiveness of a major gene for resistance to jassids in cotton. The brown planthopper resistance gene Bph-14 was recently cloned and found to encode a protein with a leucine-rich repeat (LRR) domain similar to those encoded by some pathogen resistance genes (Du et … Biffen (1905) demonstrated that the resistance gene for stripe rust in wheat was controlled by a single recessive gene. Planthoppers on resistant plants spent less time feeding than planthoppers on susceptible plants, an effect that may be directly related to callose synthesis and deposition on sieve plates (Hao et al., 2008). Developing haploid induction systems in indica rice: Various approaches to enhance anther culturability and haploids through chromosome elimination involving wide crosses, and the search for haploid inducer genes/stocks, should be given priority. What is the abbreviation for Brown Planthopper? Identification and pyramiding BPH-resistance genes is an economical and effective solution to increase the resistance level of rice varieties. Dark types have body color of brown or dark brown; light color types have tawny body color. Here, an integrated miRNA and mRNA expression profiling analysis was performed on … Increased potassium reduces planthopper susceptibility as cell walls get thicker because of greater silica uptake. Background: Among various pests, the brown planthopper (BPH) that damages rice is the major destructive pests. BPH causes serious damage to rice by sucking the rice phloem sap, ovipositing in rice tissues, and transmitting rice virus diseases such as grassy stunt virus and ragged stunt virus during its long-distance migration (Cabauatan et al., 2009). Some xylem-limited bacterial pathogens (e.g., Xylella) are apparently unable to travel from the gut to the salivary glands and require regurgitation from the foregut during vector feeding to infect the plant. The Si content of the rice stem was negatively correlated with the number of larvae bored into the stem and the amount of feces (Table 7.62). The rice brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae), is one of the most serious pests of rice in Asia. 1986, 1987). Auchenorrhyncha injure plants directly through feeding or oviposition or, more often, indirectly through the transmission of plant pathogens. This site needs JavaScript to work properly. Development of novel control strategies can be facilitated by comparison of BPH feeding behaviour on varieties … To date, over 20 Bph resistance genes have been identified from cultivated and wild Oryza species, although not all have been incorporated into resistant varieties (Bottrell and Schoenly, 2012). 3. Interestingly, much if not most of the economic damage done by spittlebugs is due to native spittlebug species colonizing nonnative hosts (e.g., introduced forage grasses, and clovers). Repetition of the study with other races or other pure line varieties, or with both. ( A ) Histochemical…, OsMYB30 binds to the AC-like elements in the promoters of OsPAL6 and OsPAL8…, NLM Here, we purified and characterized a gustatory receptor (protein) coding gene, NlGr7, from the brown planthopper (BPH) Nilaparvata lugens, which is an important insect pest of rice. For example, a Neotropical treehopper species (Aconophora compressa) has been introduced into Australia for control of Lantana (Verbenaceae). Silicon suppresses insect pests such as the stem borer, brown planthopper, rice green leafhopper, and whitebacked planthopper, and non-insect pests such as leaf spider and mites. Most of the lines carrying the desired introgressions failed to have deeper roots than IR64 (Shen et al., 2001). bph の定義が複数ある場合がありますので、bph のすべての意味については辞書で 1 つずつチェックしてください。 英語で定義:Brown Planthopper BPHの他の意味 K. Samiayyan, in Integrated Pest Management, 2014. Mol Plant. WALTER GAMS, ... KADRI PÕLDMAA, in Biodiversity of Fungi, 2004. Genome-wide identification of R2R3-MYB family in wheat and functional characteristics of the abiotic stress responsive gene TaMYB344. Towards understanding of molecular interactions between rice and the brown planthopper. B. tabaci CYP6CM1vQ is responsible for 5-hydroxylation (with some olefin formation) on the IMI imidazolidine ring (Karunker et al., 2009). In a broader sense, designer rice refers to the directed transfer of desirable alleles at target loci while retaining the key characteristics of recipient lines, which have unique adaptability because of either wider adaptation or region-specific quality traits. Few studies actually investigate the effects of insecticides other than their direct toxicity (usually LD50) on non-target animals. The Department of Agricultural Extension revealed that during this hot and dry season Rice growers in the central and northern regions observed the period of BPH (Brown planthopper) pest attack on their field. A fourth recessive gene h4 was also identified in the variety Java in Californian tests (Suneson and Noble, 1950). Desaturases are essentially required for unsaturated fatty acid (UFA) biosynthesis. Sasamoto (1958, 1960, 1961) investigated the relationship between Si content of rice and behavior of stem borer (Chillo suppressalis Walker). 2020 Nov 12;21(1):792. doi: 10.1186/s12864-020-07175-9. Taken together, our results demonstrate that the phenylpropanoid pathway plays an important role in BPH resistance response, and provide valuable targets for genetic improvement of BPH resistance in rice. Recently, Sub1, a major QTL for submergence tolerance (Xu et al., 2006), was introgressed into Swarna, Sambha Mahsuri, and BR11 mega varieties. Furthermore, reducing the use of early-season insecticides, which destroy natural enemy complexes that help regulate brown planthopper populations, is probably critical for the long-term use of resistant varieties (Cohen et al., 1997). The authors declare no competing interest.  |  Similarly, grain yield and drought resistance of the upland cultivars can be improved using major QTLs for grain yield under upland drought stress (Bernier et al., 2007) using marker-assisted recurrent selection (MARS). The goal of this review was to synthesize the complex information of phenotypically plastic wing phenotypes in aphids, brown planthoppers, and crickets with the genotypic and physiological mechanisms responsible for producing them. Among the most important are the brown planthopper, sugarcane planthopper (Perkinsiella saccharicida), corn planthopper (Peregrinus maidis), meadow spittlebug, beet leafhopper (Neoaliturus tenellus), potato leafhopper, corn leafhopper (Dalbulus spp. Brown planthopper (BPH) Nilaparvata lugens Stål is a serious insect pest of rice in Asian countries. The development and cultivation of BPH-resistant varieties is the most economical and efficient strategy to overcome the destruction caused by BPH. The brown planthopper(BPH), Nilaparvata lugens, is the most destructive insect pest in rice production worldwide.
