The damage of citrus by Scirtothrips dorsalis Hood appears to have increased since 2007 in Jeju, although the characteristics of seasonal abundance are not clear. This study was conducted to investigate the relationship between host plants and the seasonal abundance of S. dorsalis, observing plants distributed around citrus orchards. The host plants of S. dorsalis surrounding citrus orchards were determined to include 32 families, 54 species: 39 woody plant species and 15 herbaceous plant species. The host plants which related to the occurrence of 1st generation of S. dorsalis were Lonicera japonica, Clematis apiifolia, Hedera rhombea, and Viburnum awabuki. The occurrence of 1st generation S. dorsalis was estimated to be due to overwintered female adults having laid eggs into those plants from late March to early April, and the new adults having emerged from late April to late May. The host plants which were associated with fruit damage of citrus were Mallotus japonicus, and Camellia japonica, as well as creeping plants such as Clematis apiifolia, Paederia scandens and Cayratia japonica. The adult phase density of S. dorsalis caught on yellow-color sticky traps placed on the citrus trees on the edge of the citrus orchard. S. dorsalis were predominantly 3rd generation from late of June to early of July, and 6th generation from late of August to early of September, and their numbers were directly related to the degree of damage caused to the citrus fruit. The density of S. dorsalis depended on the number of new growing shoots of host plants, which indicated that the immigration of adults of S. dorsalis to the citrus was based in the suitability of host plants surrounding the orchards.

Forest fires disturb communities of forest-dwelling insects by killing or dispersal. Species diversity, species composition, and functional guilds of ant communities will be changed following forest fires. A survey of ants was conducted to find changes in ant communities after a large fire occurred in Goseong within Gwangwon province in South Korea in 1996. In total, 1,308 ants representing 16 species were collected; 696 ants representing 15 species were collected at the burned site, and 612 ants representing 13 species were collected at the unburned site. Contrary to the general expectation which predicts a decrease of diversity and abundance after fire, abundance, species diversity, species composition, and functional guilds of ant communities did not differ between the burned site and the unburned site. Furthermore, estimated species richness was significantly higher at the burned site than at the unburned site. However, monthly occurrences of ants (abundant species and pooled) were different between the burned site and the unburned site. Ants were more abundant at the burned sites than the unburned site just after the fire (May 1996). However, they were more abundant at the unburned site than the burned site in autumn (September and October 1996). This phenomenon might be caused by environmental change (e.g., decrease of soil moisture). In conclusion, the fire did not significantly change ant fauna, as fire in spring cannot destroy ant colonies that are wintering in deep soils.
Comparison of the Inhibitory Effects of Nematicides on Nematode Populations in a Regional Vinyl Plastic House
Kim, Sae-Hee ; Park, Sang-Eun ; Ko, Na-Yeon ; Ryu, Tae-Hee ; Shin, Heo-Seob ; Kwon, Hye-Ri ; Seo, Mi-Ja ; Yu, Yong-Man ; Youn, Young-Nam ;

To assess the efficacy of nematicides for the control of plant-parasitic nematodes in fruit and vegetables fields, soil samples were collected from a cucumber field at Gongju; from strawberry fields at Buyeo, Nonsan, and Jinju; and from a melon field at Gocksung in Jeonnam Province, Korea. Plant-parasitic nematodes were separated from each soil sample and identified. The susceptibilities of the nematodes to abamectin 1.68% SC, cadusafos 3% GR, dazomet 98% GR, fosthiazate 30% SL and BA12011 SL were examined under laboratory and field conditions. The average population density of plant-parasitic nematodes was generally reduced after the treatment with nematicides; however, there was increase in the population of Pratylenchus spp. in soil after treatment with fosthiazate at Buyeo and Gocksung. Furthermore, there were increased populations following treatment with abamectin, cadusafos, and dazomet at Gocksung. The control effects of BA12011 treatment on plant-parasitic nematodes were confirmed to be similar to those of the other 4 nematicides evaluated, although its control effect was higher than that of fosthiazate in cucumber-growing soil at Gongju. The effects of nematicide treatment on egg mass formation in each of the collected soils differed according to the region of soil origin. Abamectin was effective in reducing the degree of egg mass formation in Buyeo and Jinju soil, whereas BA12011 was effective in Nonsan and Gocksung soil. Dazomet was found to inhibit egg mass formation in Gongju soil. To evaluate the effect of the newly developed nematicide, BA12011, experiments were conducted in a cucumber-growing greenhouse. The average population densities of Meloidogyne spp., Pratylenchus spp., and Helicotylenchus spp. after the first treatment were reduced to a greater extent than after the second treatment. It is thus suggested that early nematicide treatment is important for effective control of plant-parasitic nematodes.
Effect of Stress Sound on the Development of the Black Soldier Fly, Hermetia illucens
Park, Jiyeong ; Lee, Sanghoon ; Lee, Hanwoong ; Kim, Yonggyun ;
Korean journal of applied entomology, volume 52, issue 3, 2013, Pages 227~237

The black soldier fly (BSF), Hermetia illucens, is a generalist detritivore that is usually exploited for recycling environmental wastes, including food remnants. These insects can also be used to produce antibiotics for medical applications. For this purpose, flies need to be mass-reared using an automatic rearing system that generates various sounds. Insects use sound as a means of communication for mating or warning against predators. Thus, extrinsic sounds may interrupt the normal physiological processes of insects. In this study, we analyzed the physiological changes due to various sound treatments at
and 8:16 h (L:D) photoperiod. At 95 dB, larvae were exposed to different sound frequencies (0-5,000 Hz). The treated larvae were adversely affected by the high-frequency sounds and showed significant reduction in pupation and adult emergence. Different sound intensities (0-105 dB) at 5,000 Hz caused significant changes in the pupation and survival of the adults at 85 dB or above. Under a stress sound condition (5,000 Hz, 95 dB), the BSF larvae exhibited aberrations in the expression of genes related to the immune system and digestion. These results indicate that high-frequency sound treatments at or above 85 dB act as a stress sound to BSF development.

Spatial Distribution Pattern of Ascotis selenaria (Lepidoptera: Geometridae) larvae in a Small-Scale of Citrus Orchard
Choi, Kyung San ; Kim, Dong-Soon ;
Korean journal of applied entomology, volume 52, issue 3, 2013, Pages 243~248
DOI : 10.5656/KSAE.2013.06.0.029
This study was conducted to understand the settlement process of Ascotis selenaria larvae into citrus orchards with respect to oviposition site and analysis of the spatial distribution pattern of the larvae. A. selenaria eggs were not found on citrus trees in field and green house, but not on citrus trees in the field. A. selenaria larvae showed a significant clump distribution in the greenhouse. In the open citrus field, the index of dispersion was around 1.0 in most cases, with a weak clumping degree. However, the d-statistic was between -1.96 and 1.96, indicating a statistically significant random distribution. In addition, the Green's index (a clumping index) was very low in all cases, even though the clump distribution was accepted. for most samples, the probability distribution of larval frequency in the field satisfied the probability distribution functions of Poisson (random pattern) and the negative binomial (clump pattern) distribution. In addition, the temporal distribution of the larvae in the open field showed a pattern which was formed by colonizers from outside oviposition sites. Further, the difference in larval spatial distribution between field and greenhouse orchards was discussed.

Cho, Jum Rae ; Jung, Jin Kyo ; Yang, Chang Yeol ; Seo, Bo Yoon ; Yum, Ki Hong ;
Korean journal of applied entomology, volume 52, issue 3, 2013, Pages 249~253
DOI : 10.5656/KSAE.2013.07.0.014
The adzuki pod worm, Matsumuraeses phaseoli (Matsumura) is an insect pest that attacks the flowers and pods of Vigna angularis. The circadian rhythms of eclosion and mating, and the effects of age and antenna ablation on mating success, were investigated. With a photoperiodic regime of 16:8 (Light:Dark) h, most adult eclosion was observed within 4 h after lights-on. Most adult mating was observed during the scotophase, although some occurred within 2 h after lights-on. However, the adults did not copulate on the day of emergence. The mating rate increased with adult age: being higher in the 4-d-old adult pairs than pairs of lower age. Most of the antennectomized males or females did not copulate with normal individuals of the opposite sex.
A Report of Two Root Mealybugs (Hemiptera: Rhizoecidae) on Non-native Ornamental Plants in Korea
Suh, Soo-Jung ; Park, Young Mi ; Cho, Myoung Rae ;
Korean journal of applied entomology, volume 52, issue 3, 2013, Pages 255~259
DOI : 10.5656/KSAE.2013.07.0.032
Two root mealybugs, Ripersiella multiporifera Jansen and Rhizoecus albidus Goux, were collected on imported Dracaena plants (Dracaenaceae) and Schlumbergera truncata (Haw.) Moran (Cactaceae) grown in greenhouses in Korea. Both species were probably introduced into greenhouses via the plant trade. Therefore, it reiterates the need to focus attention on the detection of root mealybugs at the ports of entry to prevent their introduction and establishment in the Korean environment. In this paper, additional information for the two species is provided with diagnoses, photographs along with host plant and distribution data for accurate species identification.
