Speciation processes within the Korean Peninsula based on the mites from the family Zerconidae (Acari: Mesostigmata)

Kaczmarek,,Slawomir,Marquardt,,Tomasz Korean Society of Applied Entomology 2006 Journal of Asia-Pacific Entomology Vol.9 No.3

The mesostigmatid mites speciation of the family Zerconidae in the Korean Peninsula was analysed in relation to the range of this group in the world. The Korean Peninsula is located on the edge of the Holarctic and is characterised by a uniquely diversified climate shaping the longitudinally changing flora. At present, there are altogether 40 genera included in the family Zerconidae. So far, in the Korean Peninsula there have been recognised 18 species of the Zerconidae belonging to 11 genera. The endemic genera within the area include: Metazercon, Eurozercon, Xenozercon, Koreozercon, Kaikiozercon, Aquilonozercon, and cf. Mesozercon gen. nov. A very high level of endemism (over 60%) proves the intensity of the speciation processes within the Zerconidae family on the Korean Peninsula.

A Redescription of Pseudogonia rufifrons (Wiedemann) (Diptera: Tachinidae): The First Recording of the Genus and Species in Korea

Lee,,Hyun-Suk,Han,,Ho-Yeon Korean Society of Applied Entomology 2007 Journal of Asia-Pacific Entomology Vol.10 No.2

This report describes the initial discovery of the genus Pseudogonia of the tribe Goniini (Diptera: Tachinidae) in Korea. This Old World genus currently includes seven nominal species. In the process of revising Korean Goniini, we were able to collect Korean representatives of the type species (P. rufifrons), and hereby provide the descriptions and illustrations of both sexes.

A Systematic Study of Rivellia Robineau-Desvoidy in Korea, with Emphasis on the Species Allied to Rivellia basilaris (Diptera: Platystomatidae)

Byun,,Hye-Woo,Suh,,Sang-Jae,Han,,Ho-Yeon,Kwon,,Yong-Jung Korean Society of Applied Entomology 2001 Journal of Asia-Pacific Entomology Vol.4 No.2

As a result of taxonomic study of the Rivellia basilaris and its allied species in Korea, the following five species are recognized: R. basilaris(Wiedemann), R. flaviventris Hendel, R. nigroapicalis Byun et Suh, sp. nov., R. cestoventris Byun et Suh, sp. nov., and R. apicalis Hendel. None of the above species were previously reported in Korea. We provide descriptions and illustrations of these five species as well as a key to all 11 Korean Rivellia species. We also analysed interspecific relationships among Korean Rivellia species using cladistic methods. We propose to recognize R. basilaris species-group based on the presence of two lateral occipital setae as a synpomorphy. The monophyly of the previously recognized R. syngenesiae species-group is also suported by a single synapomorphy (outer surstylus extending beyond apex of cercus).

The checklist of the taxa and the worldwide distribution of the species, including the available information of bionomics, are presented.

Evaluation of Two Commercial Strains of Phytoseiulus persimilis Athias-Henriot (Acarina: Phytoseiidae) and Laboratory-Selected, Pyrethroid-Resistant and Susceptible Strains of Amblyseius Fallacis (Garman) (Acarina: Phytoseiidae) for Pesticide Resistance

Lee,,Sang-Guei,J.,Les,Shipp,K.,Wang Korean Society of Applied Entomology 2001 Journal of Asia-Pacific Entomology Vol.4 No.2

To evaluate the pesticide resistance of two commercial strains of Phytoseiulus persimilis Athias Henriot (Koppert, Strain A; Applied Bio-Nomics, strain B) and two strains of Amblyseius fallacis (Garman) (resistant and susceptible), residual toxicity trials were conducted on greenhouse cucumber crops that were sprayed with two pesticides (pyridabern and dicofol), respectively. Strain A had significantly higher mortalities than strain B when exposed to foliage residues of pyridaben and dicofol. Strain B showed 3-18% higher survivorship than strain A when exposed to 7-to 14-day foliage residues of pyridaben at 213 and 426 ppm. When exposed to 1-and 8-day foliage residues of dicofol at 152 and 303 ppm, strain A exhibited 8-10% higher mortalities as compared to strain B. Residual toxicity of both pesticides to P. persimilis decreased significantly at the lower concentrations and over time under greenhouse conditions. Mortalities of both strains of P. persimilis were reduced by 50% when exposed to the 1-seek residues of both pesticides at the lowest concentrations. With the treatment of dicofol (303 ppm), mortalities for the two strains of P. Persimilis decreased from 53.54-42.68% at 1-day residues to 28.18-21.21% at 8-day residues. At 500 ppm of dicofol, mortalities decreased from 60.09-60.90% at 1-day residue to 35.75-34.14% at 22-day residues. However, with dicofol (1000 ppm), mortalities were as high as 61.73% at 22-day residue. The resistant strain of A. fallacies showed significantly lower mortality, as compared to the susceptible strain, when exposed to 1-and 7-day foliage residue of pyridaben at 213 and 426 ppm concentrations. Mortality of A. fallacis to pyridaben was lower than that of P. persimilis. This suggests that A. fallacis may be more compatible with the application of this pesticide to greenhouse crops than that of P. persimilis. In addition, strain B of P. persimilis may be more advantageous after the application of these pesticides in a greenhouse IPM program than strain A.

EMERGING DISEASE PROBLEMS IN KOREAN RICE AND THEIR ORIGINS

Brown,William,M. Korean Society of Applied Entomology 1976 한국식물보호학회지 Vol.15 No.1

As the technology of rice production in Korea has rapidly developed and progressed over the last few years, many problems in rice production have been solved. But with the introduction of new genetic material, the increased use of pesticides, higher fertilizer rates and closer plantings, new problems are beginning to emerge. The brown plant hopper outbreak in 1975 resulted to a great extent from some of the changes in management practices. Some rice diseases and nutritional problems that have existed in Korea but have not been considered of serious consequence, are now becoming increasingly severe and possibly as limiting as the hopper outbreak in 1975. Other diseases and nutritional problems are completely new and their cause and significance have not yet been adequately defined. In this discussion there is no Intention to state, nor is there evidence to support a statement, that any of these problems are going to be limiting factors in the future production of rice on the Korean peninsula. Rather this is an attempt to bring together some of the current field problems in Korean rice so that they can be discussed and where necessary receive suitable consideration for research and control.

Seasonal Occurrence and Morphological Measurements of Pine Sawyer, Monochamus saltuarius Adults (Coleoptera: Cerambycidae)

Han,,Ju-Hwan,Yoon,,Chang-Mann,Shin,,Sang-Chul,Kim,,Gil-Hah Korean Society of Applied Entomology 2007 Journal of Asia-Pacific Entomology Vol.10 No.1

To investigate the seasonal occurrence of the pine sawyer, Monochamus saltuarius, its emergence rate was observed in pine log and Korean white pine log conditions after the logs were cut to a regular size and placed in a netted cage. Numerical measurement was also conducted for sex ratios, fresh weight, body length and width, head width, and length of adult antennae. In the Korean white pine logs, the first day of emergence occurred on May 2, the day of peak emergence observed on May 29, and the last day of emergence was on June 10. In the pine logs, the first day of emergence occurred on May 7, the day of peak emergence was observed on May 22, and the last day of emergence was on May 30. The period of seasonal occurrence observed for the pine logs was shorter than that of Korean white pine logs. Sex ratios were 0.58; the average fresh weights of males (331) and females (379) were 0.21 g and 0.23 g; body lengths were 17.6 mm and 18.4 mm; body widths were 5.47 and 5.81 mm; head widths were 3.30 mm and 3.42 mm; and antennal lengths were 40.28 mm and 26.40 mm, respectively. The ratio of the length of the antenna to the body length was measured to be 2.0 in males and 1.4 in females.

The genus Matsumuraja Schumacher,1921 (Sternorrhyncha: Aphididae) of Korea

Lee,,Seunghwan Korean Society of Applied Entomology 2002 Journal of Asia-Pacific Entomology Vol.5 No.1

Two species of Matsumuraja (Sternorrhyncha: Aphididae) were recognized from Korea, including M. rubifoliae Takahashi, 1931 which is new to Korean fauna. Many samples of M. rubifoliae were collected on Rubus hirsutus Thunb. (Rosaceae) in Jeju Island. Redescriptions for apterous viviparous female and alate viviparous female of both species are given in detail. Key to the Korean species is constructed on the base of morphological characters and measurement data for both morphs.
