Larval spongy moth transcriptomic response to ingestion of broad-versus narrow-spectrum insecticidal Chromobacterium species.

ABSTRACT: The PRAA4-1^T strain of Chromobacterium subtsugae was the first insecticidal bacterium to be registered by the U.S. Environmental Protection Agency for use in crop protection applications since approval for Bacillus thuringiensis was granted in 1961. C. subtsugae, a Gram-negative betaproteobacterium, exhibits oral toxicity against a broad range of important insects, including dipteran, coleopteran, lepidopteran, and at least some hemipteran and tetranychidan pests. Chromobacterium sphagni is a closely related bacterium exhibiting a distinctly narrower activity spectrum than that of C. subtsugae: it is toxic to lepidopteran, but not dipteran or coleopteran pest insects. The molecular mode of activity for either species is not well characterized at present, and it remains unclear w
