The current experiment was conducted to check the efficacy of different nitrogen doses on the bionomics of maize stem borer Chilo partellus (Lepidoptera: Pyrlidae) under laboratory and field conditions applied on three maize hybrids i.e., KK-8711, KWS-55 and KS-85. The results revealed that the body weight (mg) and frass weight (mg) of larvae positively correlated with nitrogen levels. There wa...

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...

Overwintering larvae of the rice stem borer, Chilo suppressalis accumulate glycerol and are freezing tolerant to about -25 degrees C. However, non-diapausing larvae cannot accumulate glycerol and are killed by freezing. We compared the extent of tissue damage, the effects of glycerol concentration, and the transport of glycerol and water in fat body tissues from these larvae at selected freezin...

Over 2,600 transgenic rice plants in nine strains were regenerated from >500 independently selected hygromycin-resistant calli after Agrobacterium-mediated transformation. The plants were transformed with fully modified (plant codon optimized) versions of two synthetic cryIA(b) and cryIA(c) coding sequences from Bacillus thuringiensis as well as the hph and gus genes, coding for hygromycin phos...

Agrobacterium-mediated co-transformation is an efficient strategy to generate marker-free transgenic plants. In this study, the vectors pMF-2A∗ containing a synthetic cry2A∗ gene driven by maize ubiquitin promoter and pCAMBIA1301 harboring hygromycin phosphotransferase gene (hpt) were introduced into Minghui86 (Oryza sativa L. ssp. indica), an elite indica restorer line. Two independent transfo...

Sesamia nonagrioides (Lef.) is a major insect pest of sugarcane in southwestern Iran. It also damages maize and rice in this area. Using bacterial pathogens of insects as a biological control agent in an IPM program could be advantageous. In this study, the bacterial flora of S. nonagrioides were investigated in dead larvae with appearance of some bacterial disease. Samples were collected from ...

the purpose of this study was to investigate the effect of farmers' knowledge and attitude regarding farmer field school (ffs) on biological control against rice stem borer in mazandaran province. the population of the study included all farmers residing in three villages of kohnedan, rangrizmahalleh and aliabad (n=121). a questionnaire was developed from reviewed literature. the content a...

Abstract Pests and diseases are significant factors that affecting global rice production. There is a need pests have continuously been controlled, in order to solve the pest disease problem. The aim of this study was observe population dynamics infestation lowland field during different cropping seasons. data Pati District, Central Java Province, Indonesia Rainy Season (RS) 2018/2019, Dry (DS)...
