The domestic and international development of the special animal husbandry is paid much attention to at present, in order to meeting the demands of people's modern life and offer the peculiar functions. The cultivating technology development on a large scale such as the artificial feed technology on sweet potato sphinges, convolvuli Linne, which is called one of the great break-throughs of 5 great technological innovations of animal husbandry in 21st century. Compared with the situations of the traditional beasts and birds plants, a lot of valuable insects' development and utilization are restrained seriously because of its ecological characteristics are very complicated and various, the ecological mechanism is not clear, the artificial feed condition lacks technical supports. This project directed against the insect physiology ecological characteristics and its peculiar mechanisms, which studied the interrelations between the characteristics and the environmental factors emphatically in the growing of sweet potato sphinges, Herse convolvuli Linne, announced the physiology ecological characteristics, the ecological laws and the ecological mechanisms about the adaptability change reflects of sweet potato sphinges, Herse convolvuli Linne. Otherwise, the key technological schemes on artificial feeding of sweet potato sphinges, convolvuli Linne are set up. The main research results are as follows:(1) According the fifth instar larva body color types, we described the body color differentiation of different period sweet potato sphinges, Herse convolvuli Linne. In the Langli town of Changsha city in detail and carry on further investigation on relations between sweet potato sphinges, Herse convolvuli Linne and the environmental factors for the first time. The fifth instar larva body color types have 6 kinds types, the body color of larva is in close relation with the environmental factors- food, illumination, temperature are remarkable to its body color influence, With its' fetching eating, under different illumination or different temperature conditions, its body color splits up obviously. But the density and humidity has not obvious influence to the body color change of larva of sweet potato sphinges, Herse convolvuli Linne.(2) We distinguished the male and female adult through the microscope and drew its peculiar characteristic pictures. We think there are 3 kinds of ways to distinguish the male and female adult differential characteristics of sweet potato sphinges, Herse convolvuli Linne which are the adult body color, the feeler characteristics and genitals' difference.(3) According to the acquired characteristics of different period sweet potato sphinges, Herse convolvuli Linne by investigation in detail, we announced a section of laws of behavior of different period sweet potato sphinges, Herse convolvuli Linne and its life habits.(4) We dissected and watched the different period adult's internal and external reproductive system of male and female of sweet potato sphinges, Herse convolvuli Linne through the stereoscope and described its characteristics and its changes systematically for the first time.(5) The pupation medium, temperature and humidity are the main ecological factors which influence the pupation, eclosion of sweet potato sphinges, Herse convolvuli Linne. The suitable mediums are the red yellow earth, mold and sand, the water content of the red yellow earth or mold medium: 17. 5%~23. 5%, the water content of sand:4.5%~8%. The best temperature range is 26C~31C and the optimum relative atmosphere humidity is 70% ~80%.(6) We studied the influence on adult's mating of sweet potato sphinges, Herse convolvuli Linne from the mating place and space, atmosphere temperature, illumination and different age etc. described adult's mating characteristics in detail. Simultaneously, the physiological behavior reaction in the mating and the restriction relation between the ecological factors and its mating behaviors are discovered.(7) The supercooling point (SCP), the body water co...
