Aphids, Plants nd Other Organisms
Eastop, V.F. ;
Korean journal of applied entomology, volume 34, issue 1, 1995, Pages 1~8
The relationships between aphids, plants, other organisms and some physical components of the environment are reviewed. Aspects considered include year cycles, polymorphism fecundity, relationship of different groups of aphids with particular groups of plants, honeydew, alarm pheromones, aposematic colouring, camouflage, colour variation within species, morphological variation within species, multivariate analysis and problems of its interpretation, parasitism, stridulating mechanisms, predators, coevolution of plants and aphids, plant galls, trapping aphids and the interpretation of trap catches, an curation of aphid collections. References are given to sources of information about aphids, with special reference to the Korean fauna.
Sex Pheromones of Plant-Feeding Scarab Beetles
Leal, Walter-Soares ;
Korean journal of applied entomology, volume 34, issue 1, 1995, Pages 9~14
From a chemist's perspective, Scarabaeidae is one of the most exciting group of insects to work on the isolation, identification, and synthesis of sex pheromones because-as opposed to Lepidoptera, which by and large utilizes straight chain alcohols, aldehydes, and acetates-the pheromonal chemistry of scarab beetles is remarkably diverse. While species in the subfamily Rutelinae utilize pheromone constituents, which are presumably fatty acid derivatives, the more primitive species in the subfamily Melolonthinae use phenolic, amino acid derivative, and terpenoid compounds. Here, I discuss the recent advances we have accomplished in the identification of scarab sex pheromones with especial emphasis on their chemical diversity. Also, I discuss the potential role of these sex pheromones in insect pest management. Field tests revealed that, in contrast to what has been frequently observed in the Lepidoptera, the higher the dosage of sex pheromone loaded in the traps the greater the capture of scarab beetles. These data suggest that mass trapping is more likely to be useful for scarab pest management than mating distruption.

Genetical and Physiological Mechanisms of Adult Diapause in Insects
Kim, Yong-Gyun ;
Korean journal of applied entomology, volume 34, issue 1, 1995, Pages 20~32
Adult diapause in insects is characterized by suppression of reproductive development. It is induced by environmental cues such as photoperiod, temperature, food availability, and other conditions Diapause-inducing environment is recognized and analyzed by the brain of the insects. The interpreted information is conveyed via endocrine system to target tissues such as ovaries, fat body, and other tissues. From this signal hierarchy of a brain-endocrine-target tissue axis, several factors are involved to express a diapause trait in a quantitative mode, even though the insects show a binomial phenotye between being in diapause or not. Recent works estimated that the number of the factors is relatively small by a series of crossing trials between high and low diapause lines. Heritability of the diapause is quite high (ca. 70%) in some species. Epistasis, sex-linkage, pleiotropism, and other nongenetic components also affect diapause inheritance. Most physiological studies have been focused on control mechanisms of the juvenile hormone (JH) synthesis in corpora allata (CA) because JH level in hemolymph of teneral adults is critical to decide a later developmental mode. Allatostatin, an antagonizer of JH synthesis, has been believed to be a potent brain message to CA for adult diapause induction.

Korean journal of applied entomology, volume 34, issue 1, 1995, Pages 40~45
Eight field-collected populations of the two-spotted spider mites, Tetranychus urticae (Koch) from apple orchards of different geographical areas were tested for resistance to seven acaricides by leaf disk method in comparison with a susceptible strain. Marked regional variations of susceptibility were observed. Only low to moderate resistance to azocyclotin, fenpropathrin, propargite, and abamectin was obtained. However, high resistance to dicofol, fenpyroxymate, and pyridaen by eight field-collected populations was produced. Resistance to dicofol and fenpyroxymate was widespread. All of the strains tested were susceptible to one or more o the acaricides used. These results indicate that careful selection of the chemical used against any population of the two-spotted spider mite might result in satisfactory control.
Systematic Study of Criconematoidea from Korea. 2. Three Unrecorded and Five Recorded Species Criconematidae from Korea
Young Eoun Choi ; Hee Chang Jeong ;
Korean journal of applied entomology, volume 34, issue 1, 1995, Pages 46~52
Three species of Criconematidae, Criconema longulum, C. orientale and C. psammophilum are newly reported from Korea. Some morphological data and host plants of Discocriconemella hengsungica, Hemicriconemoides brachyurus, H. mangiferae, H. varionodus, and Xenocriconemella macrodora were reported.
Scientific Books and Articles on Plant Protection and Sericulture in the North Korea
Korean journal of applied entomology, volume 34, issue 1, 1995, Pages 53~60
This paper discusses scientific books and journal articles in the fields of Entomology, Plant Pathology, Weed Science and Sericulture of North Korea. Most research in the fields of plant protection and sericulture are carried out in the respective research institute of their Academy of Agricultural Sciences. But scientific papers are published in a general agricultural journal. "Bulletin of Korean Academy of Agricultural Sciences", in the case of those in the field of plant protection and in a more specific journal. "Sericulture", in the case o the other. The main interests of entomologists, plant pathologists and weed scientists seem to be how to control pests on rice, com and apple. They do not appear to have many kinds of agricultural chemicals and concentrate their control strategy on the basis of non-chemical mans. Research papers in sericulture are evenly divided between on the silkworm and the mulberry tree, including their pest control.
Stability of Dicofol Resistance of the Two-spotted Spider Mite, Tetranychus urticae Koch (Acarina: Tetranychidae)
Korean journal of applied entomology, volume 34, issue 1, 1995, Pages 61~64
Stability of resistance of the two-spotted spider mite (Tetranychus urticae) to dicofol was investigated. Resistance level (23.0-fold) of adult females to dicofol was kept up to 1 year without selection by dicofol, but was decreased to 15.8-, 10.7-fold after 2 and 3 years, respectively. Susceptibility of adult females obtained from reciprocal crosses
of the R and S stains to dicofol was declined by the success of generation.
Effect of Temperatures on the Development and Fecundity of Liriomyze chinensis (Diptera: Agromyzidae)
Korean journal of applied entomology, volume 34, issue 1, 1995, Pages 65~69
This study was carried out to investigate the development and fecundity of Liriomyze chinensis under different temperatures. Egg periods were 4.5, 2.9 and 1.9 days, larval periods 12.7, 5.8, 4.5, days, pupal periods 20.1, 16.3 and 13.0 days, and total development periods from egg to adult emergence were 32.5, 25.0 and 19.4 days under 20, 25,
of constant temperatures, respectively. Based on this results, developmental threshold temperatures were calculated as 13.0, 11.0 and
and total effective temperatures as 33.0, 86.1 and 293.6 degree-days for egg, larva and pupa, respectively. seventy-eight% of the tested files emerged within four hours and a half after lighting, and none was emerged after eight hours and a half. The longevities of male and female were 5.0 and 8.5 days and the female fly laid 165.8 eggs with her life and punctured 983.8 stipples at
Seasonal Changes in Age Structure and Fecundity of the African Mole Cricket (Gryllotalpa africana) Population in Suwon, Korea
Korean journal of applied entomology, volume 34, issue 1, 1995, Pages 70~74
A study on seasonal changes in age structure and fecundity of Gryllotalpa africana Palisot de Beauvois was conducted in Suwon from 1991 through 194. It seemed that most of newly hatched nymphs emerge to adults in September and October, so have a life cycle a year, and some overwinter as nymphs and emerge to adults from August, so have a life cycle tow years. The mean number of eggs per cell was
2.84 for egg cells laid in the laboratory, and
4.35 for egg cells collected in the field. Mean and range of the numbers of egg cells produced per female were
0.19 and 0~3.
Study on Integrated Control against Root-knot Nematode of Fruit Vegetables (Oriental Melon and Cucumber) in Vinyl House
Korean journal of applied entomology, volume 34, issue 1, 1995, Pages 75~81
To reduce crop damage from root-knot nematode, Meloidogyne spp. chemical, cultural, physical control methods were compared in commercial greenhouse for 3 years from 1992 to 1994. Timing of sol exchange for economic losses due to the nematodes is important: every 3 years for coarse sand (Masatto) and every 4 years for red-yellow soil. Control effects on Meloidogyne spp. in cucumber were 78.2% in Dazomet DP, 72.1% Carbo G+Soil reverse+submergence, and 66.3% in Carbo G+submergence. Pesticide effects were temporally different after treatment: 77.7~80.6% in 20 days and 33.7~49.5% in 60 days. Cropping system in oriental melon gave an excellent control effect of 81.1% at oriental melon/rice culture. All methods controled root-knot nematodes at the time of the treatment but the number of the nematodes increased at the end of the season. However, soil exchange was effective for 3 years. The most economic control practice is rotation with rice for every three years.
