In order to research the effects of temperature on feeding habits of Sitochroa verticalis larvae, the feeding amount and feeding rate of each instar larvae were studied at five constant temperatures (17, 21, 25, 29, 33℃) in an artificial climate box. The results showed that the feeding amount was gradually increasing with the growth of the larvae, and it was different at different temperatures in the same instar. The maximum feeding amount of larvae was 4806.85 mm2 at 25℃. Less appropriate temperature was 21, 29 and 33℃, and 17℃was the least appropriate temperature with feeding amount of 3888.53 mm2. Larval cumulative feeding amount obviously increased with the growth of larvae and the rising of temperature and fit exponential function curve. The larval feeding amounts were proportional to temperature and the growth of larvae. There were significant difference in the feeding rate of the same instars larvae at different temperature, and the maximum feeding rate was at the 5th instar. Therefore, Sitochroa verticalis forecasting and controlling in field must take into consideration some climate factors such as environmental temperature and others.
Key words
Sitochroa verticalis (L.); temperature; feeding amount; soybean
