Striped stem-borer (SSB) infestation is one of the most serious sources of damage to rice growth. A rapid and non-destructive method of early SSB detection is essential for rice-growth protection. In this study, hyperspectral imaging combined with chemometrics was used to detect early SSB infestation in rice and identify the degree of infestation (DI). Visible/near-infrared hyperspectral images...

BACKGROUND Information on the insecticide susceptibility of striped stem borer, Chilo suppressalis (Walker), is essential for an effective pest management programme. An early detection of resistance development can prompt the modification of current control methods and increase the lifespan of insecticides through the rotation of chemicals with different modes of action. In this study, the susc...

long –term use of some of insecticides on rice striped stem borer (chilo suppressalis walk.) and for the reason the urgency of use of new suspension insecticide an experiment carried out, in paddy fields under condition at rice research institute in rasht, iran.treatments were as follow;1-fipronilg in first generation 2-fipronil g. in second generation 3-fipronil sc in first generation 0.5 lit....

Gene pyramiding is an efficient approach for the genetic improvement of multiple agronomic traits simultaneously. In this study, we pyramided two foreign genes, cry1Ac driven by the rice Actin I promoter, and lysine-rich protein (LRP), driven by the endosperm-specific GLUTELIN1 (GT1) promoter, into the elite indica cultivar 9311. These two genes were chosen in an attempt to enhance insect-resis...

in order to study the effects of foliar application of si (5/1000 ratio), k (2/1000 ratio) and zn (2/1000 ratio) on rice (cv. tarom hashem), an on-farm experiment carried out based on randomized complete block design with three replications in 2012. some traits such as paddy yield and yield components, neck blast disease and stem borer damage were evaluated. results showed that the effect of fo...

Since chemical pesticides have a variety of short- and long-term social, economic, environmental repercussions, research was conducted in Baniyani, Jhapa, Nepal from January to July 2021 manage the Yellow Stem Borer (YSB) rice an environmentally responsible manner. The followed Randomized Complete Block Design (RCBD) with three replications seven treatments using spring Chaite-2. used were spin...

Species diversity, abundance, and dispersion of rice stem borers in framer's fields were studied in four major rice growing areas of Kahama District. Stem borer larvae were extracted from the damaged tillers in 16 quadrants established in each field. Adult Moths were trapped by light traps and collected in vials for identification. Results indicated the presence of Chilo partellus, Maliarpha se...
