Aluminium phosphide 燻蒸에 의한 밤바구미의 驅除
전문장,박지두 大邱大學校出版部 (대구대학, 한사대학 1988 農業科學硏究論文集 Vol.2 No.-
Aluminium phosphide was evaluated in the field for the control of the chestnut weevil(Curculio sikkimensis), using a simple polyethylene vinyl fumigation chamber. A 24-h fumigation of harvested fresh chestnuts with aluminium phosphide applied at dosages of 3g and 6g/㎥ killed about 80% of the chestnut weevil larvae inside nuts. Complete kill of the larvae was obtained when chestnuts were fumigated at a dosage of 3g/㎥ for 24 hours and the same treatment was done again after 7 days. Each treatment mentioned above also showed 100% mortality of nut fruit tortrix larvae. In addition, the undesirable effect from fumigation was not observed in healthy-nuts, and the decay rate of fumigated infested-nuts was significantly lower than that of untreated ones.

This study investigated the effects of forest-grazing of the Korean Native goats, Capra hircus, at three different areas of Kyung-sangbuk-do(Province) for a year(Oct. 1991 to Oct. 1992). The grazing of the Korean Native goats were led by leaders of the three areas. From this study, there were no significant damages of gnawing or peeling of standing trees. At the same time, soil erosion by forest-grazing was not observed either. But this study found that some damages on the browse of undergrowth trees and the herbaceous plants were observed. Especially, twiners such as arrowroot, Pueraria lobata, were favorite food for the Korean Native goats. If various field survey and researches on the forest-grazing of the Korean Native goats are performed in the future, it is possible to establish efficient management system for the forest-grazing of the Korean Native goats.
솔잎혹파리의 寄生蜂인 혹파리등뿔먹좀벌(Inostemmahockpari)의 發育生態에 關한 硏究

This study was carried out to elucidate the embryonic and postembryonic development of inostemma hockpari, an egg-larval parasite of the pine needle gall midge. Thecodiplosis japonensis, at Muan-gun, Chollanamdo, Korea, from 1984 through 1985. Inostemma hockpari and its host, Thecodiplosis japonensis are univoltine. The egg of Inostemma hockpare are pro-ovigenic and hydropic. The first instar larva of Inostemma hockpari was found in the nervous system of its host larva, and it was encysted by the tissues of thoracic and abdominal ganglia of the host. Inostemma hockpari has two larval instars.
솔잎혹파리의 生態 : 충영당의 솔잎혹파이 유충수와 유충크기와의 관계

The relationship between the larval number of the pine needle gall midge per gall and the larval body size was studied at Gwanchang-ri, Jupo-myun, Poryong-gun, Chungchongnamdo, Korea, in 1983. Larval body size was inversely related to the number of larvae per gall, but there was no intraspecific competition among the larvae in a gall.
慶北地方에서의 솔잎혹파리 寄生蜂인 혹파리반뿔먹좀벌(Inostemma matsutama)의 生態에 關한 硏究
전문장 大邱大學校出版部 (대구대학, 한사대학 1991 農業科學硏究論文集 Vol.5 No.-
This paper deals with the fundamental ecology of Inostemma matsutama, an egg-larval parasite of the pine needle gall midge, Thecodiplosis japonensis. This study was conducted in Kyongsangbuk-do, Korea, for one year (September 1990-August 1991) in order to establish control measures for the pine needle gall midge. The results obtained are summarized as follows : 1. Inostemma matsutama and its host, Thecodiplosis japonensis, are univoltine. 2. The emergence period of I. matsutama adults in the field (Youngchon area) was mid-May through mid-June and the peak emergence period (late May) coincide with that of the host. 3. Parasite females oviposit either into eggs or into newly hatched larvae of the host, and parasite eggs are synovigenic. 4. Parasite eggs do not hatch until the host reaches larval maturity (i.e, instar 3 is fully grown) and egg stage lasted about 4 months (late May-early October). The parasites pass the winter as first instars within the host larva. In the spring of the following year, the parasite larvae develop rapidly and when they mature, the host larvae die. Pupation occurs within the skin of the host puparia in late April, and the parasite adults emerge about 4 weeks later. 5. The first instar larvae of parasite attached to the ganglia in host larva. 6. The length of life of parasite adults was 9.5 days on an average at a constant temperature 15℃, with 10% honey solution for nourishment. 7. I. matsutama occurs in Youngchon and Kyongju areas of Kyongsangbuk-do(Province). 8. Percentage of parasitism(parasites) was relatively higher than that of infestation(Thecodiplosis japonensis) in the pine forests where midge population decreased to non-injurious levels following an outbreak that peaked several years ago.
