Population decrease of Scirpophaga incertulas Walker (Lepidoptera Pyralidae) under climate warming
Scirpophaga incertulas Walker is an important agricultural pest in Asia. Only few studies are available on its long-term population dynamics under climate warming. In this study, we used the linear and generalized additive models (GAMs) to analyze the historical dataset of >50 years on this pest at Xinfeng County of Jiangxi Province, China. The main objective of this study was to explore the ef...
متن کاملAssessment of Yield Loss in Rice due to Yellow Stem Borer, Scirpophaga incertulas, Using Simulation Models
The yield loss simulation (YLS) and the MACROS LIQ.CSM models were used to simulate the effect of stem borer damage at a detillering rate of 5, 15, 30, 60% at vegetative, panicle initiation and grain filing stages, on yield of rice cultivar?s Ratna. This stem borer damage during vegetative and panicle initiation stages was not simulated appropriately by both the models. Relatively MACROS simul...
متن کاملNatural Variation among Rice Yellow Stem Borer, Scirpophaga incertulas (Walker) and Rice Leaffolder, Cnaphalocrocis medinalis (Guenee) Populations to Bacillus thuringiensis δ-endotoxins
Natural variability in susceptibility of field collected rice yellow stem borer (Scirpophaga incertulas) and rice leaffolder (Cnaphalocrocis medinalis) to Bacillus thuringiensis (Bt) δ-endotoxins was investigated to establish a geographic baseline for comparison of future population responses to the increased use of Bt based insect control products like Bt transgenic rice and commercial formula...

متن کاملSilencing of CYP6 and APN Genes Affects the Growth and Development of Rice Yellow Stem Borer, Scirpophaga incertulas
RNAi is a powerful tool to target the insect genes involved in host-pest interactions. Key insect genes are the choice for silencing to achieve pest derived resistance where resistance genes are not available in gene pool of host plant. In this study, an attempt was made to determine the effect of dsRNA designed from two genes Cytochrome P450 derivative (CYP6) and Aminopeptidase N (APN) of rice...
