Report on two species of noctuid moths(Lepidoptera,Noctuidae s.l.) new to China and one new record species in Continental fauna

This paper reports two noctuid moths, Atrachea japonica (Leech, 1889) and Autographa macrogamma (Eversmann, 1842) that are new to the Chinese fauna. They are distributed in Tahe County in Daxing’anling forest region, China. In addition, a new recourd species, Neustrotia rectilineata Ueda, 1987, which is described from Mt, Sudo-san, Korea and Hotso, Prov. Taiwan, is newly added to continental fauna of the family Noctuidae s.l.. The external characteristics, genitalia photos, and the distributional ranges of those species are provided, and all the materials examined in this study are deposited in the collection of the Entomological Laboratory, Forestry college of Northeast Forestry University, Harbin, China.

Revision of tribe Archipini (Tortricidae: Tortricinae) in Northeast China.

This study was carried out to clarify the fauna of the tribe Archipini, which belongs to the family Tortricidae in Northeast China. In the present study, fifty-four species of the tribe were recognized and enumerated. Based on the present study, two species,Archips viola Falkovitsh andChoristoneura evanidana (Kennel), are reported for the first time from China. Also five species,archips dichotomus Falkovitsh,Archips similis (Butler),Argyrotaenia angustilineata (Walsingham),Choristoneura longicellana (Walsingham), andGnorismoneura orientis (Filipjev), are newly recorded from Northeast China. All available information, including host plant, distributional range, and biological information, are listed.

Bionomics of Biston betularia (L.) in Daxing'an Mountains forest area.

Observations on life cycle, habits and characteristics ofBiston betularia (L.), which is a major pest infecting birch, were made in Daxing’an Mountain forest area, Heilongjiang Province during 1997–1998. In this area, the pest has one generation per year and overwinters as eggs in cracks of the lower part of stem. Adults emerge from mid-July to late August, and the damage of larvae occurs mainly in May and June. Life cycle table ofBiston betularia was given and control suggestions were made in this paper.

Studies on Bionomics and Occurrence Regulation of Phigalia djakonovi Moltrecht

Investigation and observation were made on bionomics and occurrence regulation ofPhigalia djakonovi Moltrecht, which is a major pest of white birch, in Daxing’an Mountain forest area of Inner Mongolia during 1997 to 1999. The pest has one generation per year and overwinters as pupae in the soil in this area. Development, bionomics and outbreak of the pest are closely related with the food and environment conditions.

Effectiveness of acephate implants in protecting cones from insect damage in some conifer forests of Northeastern China

Stem implants of acephate were tentatively used to control cone and seed insects in Northeastern China in 1993. Experiments considered in a Siberian larch seed orchard and mother-tree stands of Korean pine and Korean spruce that promising control of major cone pests, including cone flies, cone-worms and seed-worms, was obtained in all of the conifer species but treatment did not reduce significantly damage due to seed chalcids. Acephate implants did not seem to affect seed germination.

Study on insect-repellent components in the volatile oils castor leaves

This paper studied the insect-repellent components from castorleaves. By Gc-Ms and UV, IR analysis, four components were identified: 2-hexanal, cyclohexyl formate, 5-methyl hexanal, 4,4-dimethyl hexanal, among them, 2-hexanal was the main insect-repellent component.
