Growth and development of Macroglossum corythus Walker (Lepidoptera: Sphingidae)

"Macroglossum corythus ( Lepidoptera : Sphingidae) was studied under laboratory conditions. External morphology of different stages of hawk moths, :egg, larval instars, prepupa, pupa, and adults was described and illustrated in this paper. Biological characteristics of each life stage are described. In an experiments in with larval were fed on the noni , Morinda citrifolia L. (Rubiaceae). Males and females were fed with honey solution. Eggs are deposited singly on the underside or upperside of noni foliage. The female hawk moth lay 64-91 eggs. The egg incubation period was 3.09±0.19 days. The mean duration time of five larval instars of hawk moth was 1.72±0.16, 1.36±0.15, 1.33±0.18, 1.50±0.35 and 4.42±0.54, respectively. The total larval period including prepupal stage was10.33±0.76 days. The pupal stage lasted 11.51±0.71. The longevity of mated males and female was 5-13 and 7-14 days, respectively. The mean head capsule width for instar 1-5 was 0.64±0.55, 1.01±0.22, 1.56±0.50, 2.42±0.04 and 3.47±0.11 mm, respectively. The larval dorsal horn lengths were 1.96±0.06, 3.93±0.12, 6.62±0.24, 8.71±0.56 and 9.84±0.76 mm, respectively."
