Host plants of Panchaetothripinae (Thysanoptera: Terebrantia: Thripidae) in New Zealand.

Based on institutional collections, database records, literature and new field collections, 247 breeding host associations were found in New Zealand for the four species of the subfamily Panchaetothripinae. The endemicSigmothrips aotearoanabred only on indigenous plants (21 species). The three adventive species,Heliothrips haemorrhoidalis,Hercinothrips bicinctusandParthenothrips dracaenae, bred on indigenous plants in native ecosystems and on other plants in and outside native ecosystems; 165, 52 and 9 species, respectively. Of the 172 plant genera, only 17 hosted more than one species. Several plant families and orders hosted only one thrips species; notably,S. aotearoanaon Orchidaceae and Loganiaceae;Hercinothrips bicinctuson Compositae (Asteraceae) and Solanales;Heliothrips haemorrhoidalison Cornales, Ericales, Fagales, Malvales, Poales, Pinales, Rosales and Vitales. The robustness and usefulness of the patterns of host plant associations for predicting plant species at risk could be tested by observations in countries with other species of Panchaetothripinae.ABSTRACT FROM PUBLISHERCopyright of New Zealand Journal of Zoology is the property of Taylor & Francis Ltd and its content may not be copied or emailed to multiple sites or posted to a listserv without the copyright holder's express written permission.
