Response of different maize accessions to pink stem borer Sesamia inferens Walker (Lepidoptera: Noctuidae)

Bacteria Isolated from the Stem Borer Sesamia Nonagrioides (lepidoptera: Noctuidae) in Iran

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 ...

Characterization and Expression of Genes Encoding Three Small Heat Shock Proteins in Sesamia inferens (Lepidoptera: Noctuidae)

The pink stem borer, Sesamia inferens (Walker), is a major pest of rice and is endemic in China and other parts of Asia. Small heat shock proteins (sHSPs) encompass a diverse, widespread class of stress proteins that have not been characterized in S. inferens. In the present study, we isolated and characterized three S. inferens genes that encode members of the α-crystallin/sHSP family, namely,...

Exploring Valid Reference Genes for Quantitative Real-Time PCR Analysis in Sesamia inferens (Lepidoptera: Noctuidae)

The pink stem borer, Sesamia inferens, which is endemic in China and other parts of Asia, is a major pest of rice and causes significant yield loss in this host plant. Very few studies have addressed gene expression in S. inferens. Quantitative real-time PCR (qRT-PCR) is currently the most accurate and sensitive method for gene expression analysis. In qRT-PCR, data are normalized using referenc...

Courtship and mating behaviour of the Mediterranean corn borer, Sesamia nonagrioides (Lepidoptera: Noctuidae)

The behavioural sequence of courtship and mating of Sesamia nonagrioides Lefèbvre males and females in laboratory cages is described. The attractant capacity of both sexes was studied by tethering males or females. The courtship and mating sequence of tethered females was the same as untethered ones, but tethered males were absolutely inactive. Age (1 day versus 2 days) did not affect the matin...
