  • It was first succeded in rearing the silkworm on the artificial diets in Japan in 1960. Since then, the researches on the artificial diets have been carried out intensively but the artificial diets have not been applied to the silkworm rearing practically till now. There are difficulties in rearing the silkworm on the artificial diets, such as uneven silkworm growth, higher production cost and decay. The results were not satisfactory, but the author hopefully expects that the artificial diet rearing would be possible for maintaining normal silkworm growth throughout improvement of diet composition, rearing techniques and aseptics add to the diets. Especially the author considered that the aseptic rearing will contribute to the research of sericultural science. Within a few years, the artificial diet rearing would be applied to the practical silkworm rearing.

  • The present study is to develop the rearing method of Gryllotalpa orientalis. In total 429 of G. orientalis were collected from the field rearing cage ($25m^2$) in 2012. Its sex ratio was 1: 1.15(Female : Male). Survival rate of the mole crickets was 94.4~86.1% with the artificial diets formulated for the present study. Successful oviposition rate was 20, 20 and 80% for one, two and three pairs of adult crickets, respectively, from the indoor rearing. The mean number of hatchlings was $11.8{\pm}21.7$, $15.7{\pm}26.4$ and $25.8{\pm}38.8$, and the mean number of dead hatchlings 1.2, 1.7 and 1.2. The mortality of nymphs on horticultural soil and clay sand mixed with ocher was 18.3 and 10.0%, respectively. The mortality of nymphs in circular and rectangular cages was, respectively, 60 and 40%.

  • A lot of individuals of Mythimna loreyi have been attracted to the sex-pheromone traps of Spodoptera frugiperda during recent few years. However, there is no information about this pest. Thus, an efficient mass-rearing method of M. loreyi is demanded to study this pest. In this study, we compared the effects of artificial diets and rearing methods on its larval development and oviposition to suggest an efficient mass-rearing method of M. loreyi. Between S. frugipera and Agrotis ipsilon artificial diets, A. ipsilon diet showed more rapid larval development with higher survivorship, and decreased pupa weights and oviposition numbers compared to S. frugipera diet. Moreover, a grouping rearing caused more rapid larva development, decreased pupa weight and survivorship compared to an individual rearing. Therefore, for mass-rearing of M. loreyi, it is considered efficient to rear the newly emerged larvae in groups using A. ipsilon artificial diet and then rearing them individually after second or third larval stadium.

  • To determine effects of temperatures and photoperiods on larval development of the mulberry longicorn beetle, Apriona germari, the larvae were reared at various rearing temperatures and under the various photoperiods on an artificial diet. The larval period of A. germari was extended as long as the temperature was lowered. Also the larval development in terms of length and weight of larvae was increased. However, survival rate during larval stage significantly decreased at 15$^{\circ}C$ and $20^{\circ}C$ than at $25^{\circ}C$ and $30^{\circ}C$. The results indicated that the favorable temperature for artificial diet rearing of A. germari fell at least above $25^{\circ}C$ constantly. In photoperiod conditions, survival rate and larval development for A. germari were obviously most effective under a photoperiod of 14L:10B. As a result in artificial diet rearing of a. germari at $25^{\circ}C$ and under a photoperiod of 14L:10D was mostly favorable in terms of larval development and period.

  • The black soldier fly, Hermetia illucens, has a worldwide distribution in the tropics and warm temperate regions and is active in the Korea from May through October. This species colonize a wide variety of decomposing vegetable and animal matter and oviposits in a variety of decomposing materials. In this study, how the black soldier fly pupation, adult emergence and mating rate changed with season at the artificial rearing system was investigated. The black soldier fly larvae and pupae were reared under laboratory condition ($27^{\circ}C$, 60% R.H.). In this study, under the laboratory condition, pupation and adult emergence were not influenced by season, but the data shows definitely different mating numbers throughout whole year. The time of the day is changed with seasons and it influence to mating on artificial rearing. To culture the black soldier fly throughout the year in Korea needs a more deep study under the artificial rearing system.

  • To establish the successive rearing method of the perilla leaf pyralid, Prausta panopealis Walker, experiments were carried out wiht three diets based on a JAMSI-type artificial die for silkworm. On the SS4 diet containing 40% of perilla leaf powder the pupal and adult yields were higher than those on th fresh green perilla leaves.

  • Decrease in the cocoon production of Japan is drastic because of low price of cocoon, scarcity of successors and so on. To tide over the difficulty, the automation system in the sericulture was discussed and some trials have been conducted by the Ministry of Agriculture, Forestry and Fisheries of Japan. The attempts are based on a low cost artificial diet which does not rely on mulberry leaves. Automatic machines developed until now are a rearing machine constituted with repeated belt conveyor, an reformation type of former rearing machine "Bombyx" and a mounting machine. Running parallel with them, utilization of 20-hydroxyecdysone extracted from a plant to the mounting was also studied to use their machines efficiently in the fields. In conclusion, 10 tons of law cocoon will come to be produced by two persons labor. At present, an automatic rearing system on low cost artificial diet has been developing for the future sericulture.

  • In natural conditions, the black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae), colonizes in warm temperate regions, and is active in Korea from May through October. Information on black soldier fly rearing, which is affected by seasonal factors in Korea, is limited. This species colonizes and oviposits in a wide variety of decomposing vegetable and animal matter. For mass rearing of black soldier flies, the egg deposition methods are dependent on sunlight and oviposition sites. In this study, we investigated the substrates and oviposition sites preferred by black soldier fly in artificial rearing system. Our results showed that as black soldier flies prefer mating under sunlight, they prefer ovipositing at sites where adequate sunlight and food substrate are available. Further detailed research is required to develop methods for artificially rearing black soldier fly throughout the year in Korea.

  • Since 1975, the studies on in vitro rearing Trichogramma spp., Anastatus japonicus Ashmead, Telenomus dendrolimusi Chu, Dibrachys cavus Walker, Habrobracon hebetor(Say), Bracon greeni Ashmead have been conducted successfully in China. The simulated “host-eggs" are made of polyethylene or polypropylene semispherical capsules, containing artificial diets, in which insectan pupal hemolymph is the main component. Manufacture of simulated “host larvae" are made of small rectangular parafilm of cotton-paper bags, containing artificial diets with insectan pupal hemolymph as the main component. Mass production of in vitro reared Trichogramma spp. and Anastatus japonicus and its utilization in the fields showed good effectiveness in controlling cotton bollworm, pine caterpillars, sugarcane borers and litchi stink bug.
