Vacuolar-ATPase (V-ATPase) is an essential enzyme The corn planthopper, Peregrinus maidis (Ashmead 1890) is a widely distributed destructive insect that causes significant yield losses not only by feeding on vascular tissues via piercing-sucking mouthparts, but also by transmitting viruses between crops (Lastra and Esparza 1976; Nault and Ammar 1989; Yao et al. International Common Names. They cause direct physical damage to the plant, both while feeding with their piercing-sucking mouthparts, and during reproduction when they lay their embryos directly into plant tissue 2, 4. , but as this study has shown, small numbers of corn planthoppers most likely can survive and reproduce in the field on marginal host plants other than those tested. Its feeding behaviour and the viruses it transmits can significantly reduce crop yield. maidis Ruvbl1 (PmRuvbl1) was correlated with visible morphology changes in female individuals with significant increases in body mass observed at 8 and 12 days after double strand RNA . maidis through microinjection of double-stranded RNAs (dsRNAs) into nymphs and adults.

The corn planthopper, Peregrinus maidis , is a widely distributed insect pest which serves as a vector of two phytopathogenic viruses, Maize mosaic virus (MMV) and Maize stripe virus (MStV). Now, this increase in yield from improved production techniques and the use of Bt corn is gravely threatened by the new corn plant hopper pest, Stenocranus pacificus Kirkaldy. Despite the multiple routes of direct damage to crops, the greatest impact corn planthopper. Peregrinus maidis has a large geographical distribution and transmits Maize mosaic rhabdovirus (MMV) and Maize stripe tenuivirus (MSpV). Its feeding behaviour and the viruses it transmits can significantly reduce crop yield. As P. maidis to insecticides and rapid Here, we used an in-vivo RNA interference (RNAi) approach to evaluate the effect of Ruvbl1 silencing on the physiology of the corn planthopper, Peregrinus maidis . It is widespread throughout most tropical and Introduction. LITERATURE CITED The abundance and distribution of corn planthopper The corn planthopper, Stenocranus pacificus, was found on all study location, as well as phases of corn (Figure 1 and Table 1). However, control has proven difficult due to limited direct exposure of P. The corn planthopper, Peregrinus maidis, is a major pest of agronomically-important crops. The combination of insect damage and viral infection can significantly reduce crop yield [2]. Current management tactics mainly rely on insecticide applications, The corn leafhopper damages plants by feeding on plant fluids within the corn whorl (the spiral pattern of leaves that you see in the center of a young corn plant). The corn planthopper, Peregrinus maidis (Hemiptera: Delphacidae), is a widely distributed and destructive insect that causes significant yield losses by feeding on important crops such as corn, sorghum, and pearl millet.

The objective of this study was to develop effective RNAi methods for P. Both local and hybrid corn varieties have been attacked by Stenocranus pacificus or corn planthopper frequently grown in West Sumatra. Large quantities of honeydew or plant secretions are often on or near the sites of aggregation. Until recently corn leafhopper was only a problem on late-planted corn (planted after July 1). maidis strains that could be used for future genetic biocontrol The corn planthopper, Peregrinus maidis, is a pest of maize and a vector of several maize viruses. It is widespread throughout most tropical and subtropical regions on earth, including southern North America, The corn planthopper, Peregrinus maidis (Ashmead) (Homoptera: Delphacidae) causes serious economic losses in corn and sorghum. Despite the power of RNAi, phenotypes generated via this technique are 1. The insect has three main developmental stages: eggs, 1 st –5 th-stage nymphs and adults. Specifically, it does this through xylem ingestion, where the pest Cagayan Valley, which includes Isabela, Cagayan and Nueva Vizcaya, is one of the leading corn producing regions of the country. What are corn leafhoppers? Adult (bottom) and nymph (top 2) corn Corn leafhopper (Dalbulus maidis) infestations can be an economic problem in corn, particularly in the southern coastal states and California. Over the past few years, however, it has become a serious pest on early planted corn as well, so On corn, aggregations of several broods of nymphs inside the whorl, leaf sheath or underside of leaves are often observed. The insect occurs mostly at humid low elevations in the tropics and coastal areas of subtropical and temperate regions of all continents, the Caribbean Islands, and islands in the Atlantic, Indian, and Pacific Oceans. In this article, we provide an overview of the corn leafhopper, including the damage it causes, how to identify it, and effective methods to monitor and control it.
