Effect of temperature and CO₂ on population growth of South American tomato moth, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) on tomato
Journal of Economic Entomology 111 (4), 1614-1624
Abstract: The effects of different temperatures (26, 28, 30, and 32°C) and CO₂ concentrations (380 and 550 ppm) on the life table of Tuta absoluta were evaluated. The life history raw data of T. absoluta were analyzed by using the age-stage, two-sex life table. Results showed that increase in temperature reduced the larval developmental time of T. absoluta, whereas the elevated CO₂ concentration (eCO₂) extended the larval developmental time. Highest fecundity rate was recorded at 30°C at ambient CO₂ (aCO₂) condition (88.10 eggs). Total fecundity significantly reduced under eCO₂ at 28°C and 30°C. There was a 5–10% higher mortality observed under eCO₂ than aCO₂ condition. With rise in temperature from 26–30°C, T. absoluta reared under eCO₂ condition showed lower net reproductive rate, intrinsic and finite rate of increase in comparison to aCO₂. However, these parameters started decreasing at 32°C under both eCO₂ and aCO₂ conditions.
