New host records for Caliothrips striatus (Thysanoptera: Thripidae) on Magnolia spp. with the description of the second instar

Abstract

Previous reports of Caliothrips striatus Hood implied that the species is mainly found on L. tulipifera and only occasionally on Magnolia species. Results from the current study clarify the known hosts of C. striatus which include L. tulipifera and 9 Magnolia spp. The discovery of numerous adults and larvae on the leaves showed that M. grandiflora is a host used for feeding and reproduction by C. striatus.
