Background Genomic approaches provide unique opportunities to study interactions of
insects with their pathogens. We developed a cDNA microarray to analyze the gene
transcription profile of the lepidopteran pest Spodoptera frugiperda in response to injection
of the polydnavirus HdIV associated with the ichneumonid wasp Hyposoter didymator.
Polydnaviruses are associated with parasitic ichneumonoid wasps and are required for their
development within the lepidopteran host, in which they act as potent immunosuppressive …

Gene expression profiling of Spodoptera frugiperda hemocytes and fat body using cDNA
microarray reveals polydnavirus-associated variations in lepidopteran host genes transcript
levels … Acceptable use policy … transcriptional variations; expression génique; relation
hote parasitoide; cdna microarray …
