Oviposition model of Carposina sasakii (Lepidoptera: Carposinidae)

Adult longevity, survival, and fecundity of Carposina sasakii Matsumura were investigated at 15, 18, 20, 25, 30, and 35 °C, and an oviposition model was developed. The temperature affected adult longevity, survival, and fecundity. Overall, the longevity decreased as the temperature increased and the female adult developmental rates (1/median longevity) were well described by the modified Sharpe and DeMichele model in the rage of 15–35 °C, and were used to calculate the adult physiological age. Total fecundity was the highest at 20 °C, and then declined steadily thereafter. The relationship between total fecundity and temperature was well described by a nonlinear equation. The cumulative age-specific oviposition rate was well described by the two-parameter Weibull function. The overall adult survival exhibited a reverse logistic curve. Three temperature-dependent components, total fecundity, age-specific oviposition rate, and age-specific survival rate, were incorporated into the oviposition model. Oviposition model simulation well described the field occurrence patterns of C. sasakii egg population.
