The aim of the study was to determine the relationship between the natural enemies' performance and the BPH performance In this article, DOI: ne Corpus ID: ; Molecular identification and eco-friendly management of rice brown planthoppers in Bangladesh Adult hopper is mm long and has a yellowish brown to dark brown body. A The Brown Plant Hopper (BPH), Nilaparvata lugens (Homoptera: Delphacidae) is one of the most destructive insect pests causing significant yield loss in most of the rice The study was undertaken to demonstrate the management of Brown plant hopper (BPH), Nilaparvata lugens in rice with formation of Alleyways ofcm for everymetre, Planthopper. AroundBPH resistance genes have been identified so Following the brown planthopper feeding, the symp­ toms of the hopperburn injury first appear on the rice plants as yellowing of the leaf blades of olders, and progress to extent that the entire above-ground parts of the plants turn brown and die The brown planthopper (BPH), Nilaparvata lugens (Stål), is one of the most economically important insects which can cause huge destruction of rice plants (Xue et al.,) The Brown planthopper (BPH), also known as Nilaparvata lugens (Stal.) (Homoptera: Delphacidae), is a major insect pest in several Asian nations, including India. These are the brown planthopper (BPH), Nilaparvata lugens (Stal); and the whitebacked planthopper (WBPH), Sogatella Brown Plant Hopper (BPH) A sucking insect that, under heavy infestations, can cause wilting and complete drying of rice plants known as ‘hopperburn’. Both adults and Brown planthopper, Nilaparvata lugens is an economically important insect pest of rice, causing crop losses of upto% in favourable microclimatic conditions. Understanding the biology and ecology of this pest will enhance the designing Brown planthopper (BPH, Nilaparvata lugens Stål) is the most devastating pest of rice in Asia and causes significant yield loss annually. The wings are sub hyaline with a dull yellowish tint. Two species of planthopper infest rice. The introduction of high yielding and BPH-susceptible rice cultivars, synthetic chemical fertilizer use, continuous cropping, staggered planting, and indiscriminate insecticide treatment have all contributed to India’s growing BPH The study was undertaken to demonstrate on the management of brown plant hopper (BPH), Nilaparvata lugens in rice with formation of alleyways, recommended dose of nitrogen fertilizer, alternate wetting and drying, spraying of pymetrozineWG g/l and spraying azardiractin ppm 5ml /l for adult management Brown planthopper (BPH) are one of the main pests of rice plants, their abundance is influenced by biotic and abiotic factors such as the presence of predators (natural enemies). Following the brown planthopper feeding, the symp­ toms of the hopperburn injury first appear on the rice plants as yellowing of the leaf blades of olders, and progress to Brown planthopper (BPH) are one of the main pests of rice plants, their abundance is influenced by biotic and abiotic factors such as the presence of predators (natural In this study, risk model was developed taking into account weather factors as a significant variable that affects the number of brown planthopper populations in the light trap. It has two characteristic wing morphsBrown planthopper (BPH) is a serious pest of rice and has tremendous impact especially in Asia-Pacific region.
