Liriomyza sp. A (apparently undescribed)

NEW STATE RECORD

Specimens of this leafminer were reared from blotch mines on the leaves of crown flower ( Calotropis gigantea ) and tropical milkweed ( Asclepias curassavica ) planted at the University of Hawaii at Manoa . Adults and associated host plant damage appeared to be new to Hawaii and specimens were sent to USDA-ARS-SEL, then referred to Owen Lonsdale at the Canadian National Collection of Insects, Arachnids and Nematodes.

According to O. Lonsdale, this leafminer appears to be an undescribed species of Liriomyza most closely related to L. asclepiadis and L. subasclepiadis . Larvae produce blotch mines on leaves of Calotropis gigantea . Populations of this undescribed Liriomyza sp. appears to be controlled on Oahu by several locally established parasitoids, including Closterocerus utahensis Crawford and Chrysocharis sp. (Eulophidae- larval endoparasitoids) and Digliphus begini (Ashmead) ( Eulophidae ), a larval ectoparasitoid.
