چکیده

Due to the high demand for pest control in Sri Lankas’ rice paddy cultivation practices, the number of new pesticides has been recently introduced. However, the new pesticides, which are flowing into the agriculture sector of Sri Lanka, appeared to be used by farmers without obtaining proper application guidance from the suppliers or from extension services. As a result, the exposure to harmful pesticides is increasing and the excessive use of them generates environmental, social, and economical problems. Therefore, a commitment to new strategy in pest management is needed, in order to ensure the suitable and efficient pest management method in Sri Lankas’ rice farming sector, along with maintenance of the environmental standards in the country. The aim of this thesis is to analyse the current pest management methods used in Sri Lanka to control the out breaks of Rice Stem borers (Scirpophaga incertulas) and their short and long term impacts on environment, economical and social sectors. Moreover, this study investigates the possibilities of introduction of a combination of pest management methods into the agriculture sector of Sri Lanka, in order to overcome the negative impacts on environment, economic, and social sectors. The findings are that the existing conventional pest control methods contradict with the sustainable agriculture concept. This study suggests that traditional pest management practices could play an important role in achieving sustainable pest management method by influencing the decrease of excessive usage of pesticides

Assessment 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...

RNA-seq of Rice Yellow Stem Borer Scirpophaga incertulas Reveals Molecular Insights During Four Larval Developmental Stages

The yellow stem borer (YSB), Scirpophaga incertulas, is a prominent pest in rice cultivation causing serious yield losses. The larval stage is an important stage in YSB, responsible for maximum infestation. However, limited knowledge exists on the biology and mechanisms underlying the growth and differentiation of YSB. To understand and identify the genes involved in YSB development and infesta...

Field survey and greenhouse evaluation of non-rice host plants of the striped stem borer, Chilo suppressalis (Lepidoptera: Pyralidae), as refuges for resistance management of rice transformed with Bacillus thuringiensis toxin genes.

The striped stem borer, Chilo suppressalis (Walker) (Lepidoptera: Pyralidae), is the most abundant stem borer of rice Oryza sativa L. (Poaceae) in temperate Asia. Chilo suppressalis also occurs throughout the tropical rice-growing areas of Asia, where it is generally second in abundance to the yellow stem borer, Scirpophaga incertulas (Walker) (Lepidoptera: Pyralidae) (Pathak & Khan, 1994). Ste...

A Study of Paddystem borer (Scirpophaga Incertulas) Population Dynamics and its Influence Factors Base on Stepwise Regress Analysis

Paddystem borer (Scirpophaga incertulas) is a serious rice pest. The damaged plants wither into dead tassel or white tassel. Such damage leads to decreased in rice production. In order to control the damages of paddystem borer efficiency, it is very important to analyze and study the regulation of population dynamics and the related factors affecting the development. This investigated the popul...
