The golden twin-spot moth or tomato looper, Chrysodeixis chalcites (Esper), is a polyphagous and worldwide pest
that causes important aesthetic damages to banana fruits in the Canary Islands. The life history parameters of
C. chalcites were determined under laboratory conditions in base on the age-stage, two-sex life table at 15, 20, 25,
30, and 35°C, 65% relative humidity (RH), and a photoperiod of 16:8 (L:D) h, when it was reared on a semi-synthetic
diet. The results show that C. chalcites was able to develop and survive from 15 to 30°C, but no development
occurred at 35°C. Developmental threshold temperatures of the egg, larval, pupal, and total preoviposition stages
were 10.42, 11.73, 11.22, and 9.42°C, respectively, and their effective accumulated temperatures were 58.31, 265.96,
118.57, and 562.39 degree-days, respectively. The adult longevity was reduced with increasing temperature, which
ranged between 16.27 and 34.85 d for females and between 14.27 and 35.21 d for male...
