Diptera rearing DNA barcoding Tephritidae Trypeta

Abstract

A leafminer reared in California from Cape ivy (Asteraceae: Delairea odorata Lem.), an invasive plant introduced from South Africa, is identified as Liriomyza temperata Spencer (Diptera: Agromyzidae). This is believed to be a novel host association for a native Nearctic fly, which appears to have been introduced in Hawaii along with Cape ivy. Liriomyza tricornis Lonsdale syn. nov. is treated as a junior synonym of L. temperata. There are no previous host records for either taxon. We review previously published rearing records of North American Liriomyza spp. from other plants in the tribe Senecioneae, as well as observations of unidentified Liriomyza mines on these plants. We also discuss the leaf mine and DNA barcode of an undetermined Trypeta sp. (Diptera: Tephritidae) found mining leaves of Cape ivy in California.
