Abstract

the mean measurements of head capsule width and larval body length, width and weight of M. boninensis reared on sterilized eggs of C. cephalonica were 0.44, 0.74 and 0.81 mm, 2.80, 4.92 and 7.16 mm, 0.81, 1.67 and 2.27 mm and 0.86, 5.72 and 11.01 mg, for I, II and III larval instars, respectively. the corresponding values on unsterilized eggs and neonates of C. cephalonica were 0.44, 0.57 and 0.76 mm, 2.82, 4.30 and 7.19 mm, 0.83, 1.37 and 2.38 and 0.90, 5.97 and 10.92 mg and 0.42, 0.48 and 0.73 mm, 2.75, 3.77 and 6.03 mm, 0.80, 1.24 and 2.04 mm and 0.69, 3.72 and 8.80 mg, respectively. the progression factors for larval head capsule width and body length, width and weight on sterilized eggs of C. cephalonica were 1.39, 1.61, 1.73 and 4.29 for I to III instars, respectively. the corresponding values for unsterilized eggs and neonates of C. cephalonica were 1.32, 1.60, 1.70 and 4.23 and 1.33, 1.49, 1.60 and 3.88.
