Insects were fed eggs of Anagasta kuehniella, and reared at 24.5±1ºC, 70±10% relative humidity, with a 12‑hour photophase. Hippodamia convergens took about 1.6‑day to complete development, longer than H. axyridis, and 2.4‑day longer than C. sanguinea. At immature stages, H. axyridis exhibited the highest survival percentage (49.2%), in comparison to the other coccinellids. For mean adult longevity, H. convergens was deficient, in comparison with the other species. Mean period of pre‑oviposition was the longest in C. sanguinea; the longest oviposition time occurred for H. axyridis; and the post‑oviposition period was similar between the coccinellids. Considering the reproductive parameters, H. axyridis showed the best performance in all aspects. For life table, the values of H. convergens were higher than, although close, to those of H. axyridis. Nevertheless, the high net reproductive rate of H. axyridis showed this species potential to increase population size. The biological characteristics of the exotic H. axyridis favors its invasion and establishment in Brazil, corroborating results noticed in other countries.  aBiological control  aDevelopmental stages  aHippodamia convergens  aInvasive species  aControle biológico  aCycloneda sanguínea  aEspécie invasora  aFase de desenvolvimento  aLife table  aTabela de vida1 aFERNANDES, F.
