Abstract

The biology and host specificity of the psyllidHeteropsylla spinulosa Muddiman, Hodkinson & Hollis collected fromMimosa invisa Von Martius, was studied in Brazil and in Australia. Oviposition was recorded on 19 of 100 plant species tested but nymphs died without feeding, except onM. invisa. H. spinulosa was shown to be specific toM. invisa and was subsequently released and established in Australia and Western Samoa.

Résumé

La biologie et la spécificité du psyllideHeteropsylla spinulosa Muddiman, Hodkinson & Hollis récolté surMimosa invisa Von Martius ont été examinées au Brésil et en Australie. On a observé l'oviposition sur 19 des 100 espèces de plantes examinées, mais toutes les larves sont mortes sans se nourrir, à l'exception de celles qui étaient surMimosa invisa. On a montré queHeteropsylla spinulosa est spécifique deMimosa invisa; le psyllide a donc été introduit et il s'est établi en Australie et en Samoa-Occidentale.
