The larval development of beet armyworm spodoptera exigua huebner lepidoptera noctuidae by the widths of the head capsule



The larval development of beet armyworm spodoptera exigua huebner lepidoptera noctuidae by the widths of the head capsule



Korean Journal of Applied Entomology 30(1): 54-57



The width of head capsule of the beet armyworm, Spodoptera exigua (Hubner), was measured on the 5th generation larvae reared with artificial diet. The mean widths of head capsule of each instar were: 1st, 0.246 mm; 2nd, 0.35 mm; 3rd, 0.546 mm; 4th, 0.809 mm: 5th, 1.242 mm; and 6th, 2.185 mm. The coefficient of variation (%) of each instar were: 1st, 8.6; 2nd, 9.5; 3rd, 15.1; 4th, 11.2; 5th, 12.0; and 6th, 12.9. The growth ratio of each instar were: 2nd, 1.43; 3rd, 1.55, 4th, 1.48; 5th, 1.54; and 6th, 1.76. The fitness (%) to Dyar's law of the measurement of head capsule width were: 1st, 94.7; 2nd, 98.3; 3rd, 98.7; 4th, 94.8; 5th, 94.6; and 6th, 92.2. When the logarithm of the width is plotted against the number of instars, the calculated regression line is highly significantly (Log Y = -0.819 + 0.1872X, r2 = 0.9977**) and Dyar's constant was 1.54.
