Interpretive Summary: The tarnished plant bug is replacing caterpillar pests as the primary pest of Delta cotton. A basic set of gene sequences for tarnished plant bug has been depositied in the public gene repository GenBank. Most of the identifiable genes are associated with basic cellular processes, but some of the gene sequences appear to be associated with feeding and digestion. These gene sequences will help scientists understand the basic biology of this pest and similar insects. They will also be the key to development and and testing of new pesticides and novel genetic pest control methods.
Technical Abstract: Expressed seqeunced tags (ESTs) were prepared to establish an initial baseline for molecular genetic studies of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois). One hundred and forty-two of the 276 unique ESTs were from genes not previously identified from any organism. The largest class of identifiable ESTs (15.2%) were from genes involved in cellular metabolic functions including physiological processes. Twenty-seven ESTs (9.8%) were from genes associated with transcription and translation, including ribosomal genes. Twelve sequences appear to be associated with feeding and digestion, and may be targets for pest control studies.
