Rhodomyrtus tomentosa (Myrtales: myrtaceae): New host records for Metanastria gemella (Lepidoptera: lasiocampidae) and Arna bipunctapex (Lepidoptera:lymantriidae). Florida Entomologist. 96(2):641-642. 2013.

Interpretive Summary: Surveys for host specific natural enemies of R. tomentosa in China (mainland and Hong Kong) resulted in the discovery of two lepidopteran species that have not been previously reported as herbivores of the plant: Metanastria gemella and Arna bipunctapex. Multiple generations of both species were reared on R. tomentosa in a quarantine laboratory, demonstrating that the plant is a developmental host. However, neither species demonstrates sufficient host specificity to be considered for biological control of R. tomentosa in the USA.
