Fulgoromorpha)

Abstract


Lacertinella australis is distributed in 11 provinces of Argentina and has been mentioned as a species of phytosanitary concern because of its potential for the transmission of pathogens. Considering its wide range of distribution, its potential phytosanitary importance and the invasive nature of its principal host plant Cortaderia spp., life cycle aspects were evaluated through a life table under controlled conditions in the laboratory and a second table based on samples of natural populations. Population parameters R0, λ, rc, Vx, Tc and the average development time by stages were estimated. Behavioral and bionomic aspects of L. australis were recorded and compared with the only two species of the tribe Saccharosydnini whose biology is known: Saccharosydne procerus and Saccharosydne saccharivora.
