Other claims from this paper (7)
- Intervention effect Fecundity of Caryedon serratus was highest at 25°C and decreased as temperature increased
- Intervention effect Net reproductive rate decreased from 159.07 viable eggs/female at 25°C to 101.94 eggs/female at 40°C
- Intervention effect Mean generation time decreased from 166.52 days at 25°C to 59.31 days at 40°C
- Intervention effect Intrinsic rate of increase, innate capacity for increase and finite rate of increase increased with temperature from 25 to 40°C
- Observation Intrinsic rate of increase varied from 0.0316 to 0.0784 females/female/day between 25°C and 40°C
- Intervention effect Population doubling time was shortened to 8.96 days at 40°C compared with 21.94 days at 25°C
- Observation Fecundity, survival rates and developmental time of Caryedon serratus differed among temperatures
