ABSTRACT: In many Asian countries, the silkworm (Bombyx mori) is economically important as a main silk-producing
insect. Pesticide pollution often causes huge economic losses to the sericulture. Digital gene expression (DGE) was
performed to investigate the gene expression profiles of Lan5 (sensitive) and Mysore (tolerant) silkworm strains at 48
h after exposure to fenvalerate. The results showed that a total of 1,575 differentially expressed genes (DEGs) were
detected in the Lan5 DGE library, and 1,485 DEGs were detected in the Mysore DGE library. The possible functions of
all DEGs in biological process, cellular component, and molecular function were determined using the gene ontology
(GO) classification system. Pathway enrichment analysis was carried out using the Kyoto Encyclopedia of Genes and
Genomes (KEGG) database. Furthermore, some selected DEGs were verified using quantitative real-time PCR (qRTPCR). These findings provide abundant data on the effect of pesticide exposure on insects at the molecular level and a
new clue to control strategy of Lepidoptera pests.
