BORTOLI, Lígia Caroline; BERTIN, Aline; EFROM, Caio Fábio Stoffel  e  BOTTON, Marcos. Biology, fertility life table and effect of insecticides on Spodoptera eridania (Cramer) (Lepidoptera: Noctuidae) in strawberry and grape. Rev. Bras. Frutic. [online]. 2012, vol.34, n.4, pp.1068-1073. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452012000400013.

The biology of Spodoptera eridania was studied in the laboratory (22±1ºC, RH 70±10%, 14 hours of photoperiod) in leaves of strawberry (Fragaria x ananassa cv. 'Aromas') and grape (Vitis vinifera cv. 'Cabernet Sauvignon'). The duration and viability of the entire cycle were respectively 52.2±1.32 days and 37.6% for strawberry and 42.2±0.45 days and 25.5% for grapes. The sex ratio in strawberry was 0.58 and 0.48 on grape. The average longevity of males and females in strawberry was 16.3±1.16 and 15.8±1.85 days, respectively, and 5.6±0.88 and 7.3±0.83 days in grape. The mean fecundity was 1,747.5±187.32 eggs per female in strawberry and 1,764.9±289.04 on grape. The life table of fertility showed that the net reproduction rate and finite rate of increase were 394.89 and 1.10, respectively, for strawberry and 213.98 and 1.12 for grapevine. Strawberry cv. 'Aromas' and grape cv. 'Cabernet Sauvignon' are suitable hosts providing similar population growth rates of S. eridania.
