effective qualitative traits in resistance mechanisms of rice varieties to stem borer (chilo suppressalis (walker)
the use of resistant cultivars remains one of the most reliable methods to manage the pests. in this study the mechanism of resistance in 10 lines of rice for 3 kinds of resistance (antixenoses, antibioses and tolerance) was studied. the egg set of striped stem borer on the leaf of considered lines for antixenoses and larva weight mean and survival percentage of larva were evaluated for antibio...
متن کاملevaluation of rice stem borer's damage chilo suppressalis walker (lepidoptera: pyralidae) on different rice varieties
in order to evaluation of rice stem borer's damage (chilo suppressalis walker), on rice cultivars an experiment was carried out by two factors, (three cultivars and five spraying times), in completed randomized block design an factorial sampling was conducted on the hills infested to deadhearts (d.h), whiteheads (w.h) and yield loss. five hills were randomly selected from each plot and...
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 کاملEvaluation of Rice Promising Lines for Resistance to Striped Stem Borer in Field Conditions
In this study, the mechanism of resistance to striped stem borer was investigated in 10 rice genotypes and at different levels of nitrogen fertilizer. In addition, the relationship between some quantitative and qualitative traits of rice genotypes was evaluated with the resistance to striped stem borer.This experiment was conducted as split plot based on randomized complete block design with...
متن کاملLaccase-type phenoloxidase in salivary glands and watery saliva of the green rice leafhopper, Nephotettix cincticeps.
The activity and composition of leafhopper saliva are important in interactions with the host rice plant, and it may play a physiological role in detoxifying toxic plant substances or ingesting sap. We have characterized diphenoloxidase in the salivary glands of Nephotettix cincticeps, its activity as a laccase, and its presence in the watery saliva with the objective of understanding its funct...
