| Abstract: | The days and rates of development, developmental zeros and effective constants of temperature in egg, larval and pupal stages and pre-oviposition period of experimental beet armyworm (Spodoptera exigua (Hiibner)) population were tested. The regression equations of the rates of hatching, larval survival and emergence and population trend indices complied with temperature were determined as: SE = -76. 77 12. 4888X-0. 2465X2; SL=-99. 1037 14. 5438X-0. 279X2;SP = 29. 8022 9. 256X-0. 1756X2; and 1=1144. 957 101. 013X-1. 9716X2, respectively. Under 24~28C, the female moths laid more eggs, ranged from 502 to 608 eggs/female. |
