DOI : 10.5656/KSAE.2013.12.0.070
This study was conducted to determine the economic injury levels and control thresholds for the striped cabbage flea beetle, Phyllotreta striolata (Coleoptera: Chrysomelidae), on Chinese cabbage at two different planting times. The number of inoculated adults per 10 cabbages was 0, 2, 4, 8, and 16 at the early developmental stage of the cabbage5 days after planting) and 0, 10, 20, 30, and 40 at the middle developmental stage (30 days after planting). Damages to the leaves at the first inoculation were 2.5-21.1% and at the second inoculation were 1.8-26.3% after harvesting. The linear relationships between population density and yield reduction were as follows: Y = 1.3475X + 2.135 (
= 0.8699) at the early developmental stage and Y = 0.703X - 1.78 (
= 0.966) at the middle developmental stage. On the basis of these results, the economic injury levels caused 5% loss of yield; there were 2.1 adults per 10 Chinese cabbage at the early developmental stage and 9.6 adults per 10 Chinese cabbage at the middle developmental stage.

In a faunal survey of the Gelechiidae (Lepidoptera: Gelechioidea) from Is. Ulleung-do in the East Sea of Republic of Korea, one species of Gelechiidae, Bagdadia gnomia Ponomaranko, is reported for the first time from Korea and an unknown species of the genus Bryotropa was discovered. In addition, eight species of Gelechiidae including a little known species, Dichomeris anisacuminata Li & Zheng, were first recorded from Is. Ulleung-do. Images of adults and genitalia for the newly recorded species and a little known species are provided.

The efficacy of mating disruptors MD-IKR (Isomate-KR) and MD-CR (Confuser-R) for controlling Grapholita molesta (Busck) and Carposina sasakii (Matsumura) was evaluated in non-chemical or organic apple orchards. For G. molesta, the efficacy of MD-IKR and MD-CR in Chilgok was 99.8 and 99.8% (2011) and 92.4 and 96.7% (2012), respectively, showing different mating reduction values. The efficacy of MD-IKR and MD-CR in Cheongsong was 99.1 and 92.8% (2011) and 99.6 and 99.6% (2012), respectively. For C. sasakii, the efficacy of MD-IKR and MD-CR was 100% at Chilgok and Cheongsong in 2011 and 2012. Evaluation of the shooting and fruit damage rates showed that the efficacy of the mating disruptors in controlling G. molesta and C. sasakii was better than that of the non-control. However, there was no significant control difference between using the mating disruptors and the conventional control. No difference in the efficacy of the two mating disruptors was observed. We believe that MD-IKR could be an alternative to MD-CR.

A revised checklist of host plants for 181 species belonging to 103 genera in six subfamilies of Cerambycidae (Coleoptera: Chrysomeloidea) in Korea is provided on the basis of the results of field surveys and literature review. A total of 14 new cerambycid-host associations are confirmed and the Manchurian striped maple, Acer tegmentosum Maxim. (Aceraceae), is listed as a new host of the Asian longhorn beetle, Anoplophora glabripennis (Motschulsky). The names of more than 170 host plants species belonging to 107 genera in 44 families are compiled. Among them, four families (Ulmaceae, Pinaceae, Fagaceae and Betulaceae) are confirmed as the main host families (more than 23%) of most of the cerambycid species. All invalid scientific names and Korean names of plants and cerambycids in the previous literature are corrected in the present paper.

Pinewood nematode (PWN: Bursaphelenchus xylophilus) is known to kill pine tree species that are indigenous to countries where the pest was inadvertently imported, but some cultures from the extraction of dead pines do not damage trees. Experiments were conducted to examine the effect of pre-inoculation of these low-pathogenic pinewood nematode on resistance of pine trees against the pest species. The pre-inoculated pine saplings showed induced resistance which lasted for a year, and repeated inoculation of these low-pathogenic nematodes enhanced tree resistance. All nematode samples extracted from dying or dead pines that had been killed not more than three months before the extraction were pathogenic, and most of those extracted from pines that had been killed 2-3 years before were low-pathogenic. When inoculated in pine saplings, number of low-pathogenic nematodes settled, as studied two days after inoculation, was not different from that of pathogenic ones. However, as studied after 30 days of inoculation, rate of reproduction in low-pathogenic nematodes was far lower than that of pathogenic nematodes. The rate of reproduction of several nematode isolates growing on fungal mat media of Botrytis cinerea varied, but three of four low-pathogenic isolates showed same level of reproduction rates as pathogenic ones.

The resistance levels of the green peach aphid, Myzus persicae (Sulzer), against 10 insecticides was checked and selected the applicable insecticide resistance markers. We conducted our study in 5 cabbage cultivation regions (Pyeongchang, Hongcheon, Bongwha, Muju, and Jeju) of Korea, over 3 successive years (2009-2011). We selected a multi-resistant (MR) strain from among the 5 field-collected populations. We analyzed esterase over-expression and mutation(s) in the target sites, by using native isoelectric focusing (IEF) and quantitative sequencing (QS). We detected esterase over-expression and StoF mutation in the acetylcholinesterase 1 gene (ace1) in all of the field-collected populations, including the MR strain. We did not detect the LtoF mutation, which is a well-known knockdown resistance (kdr) mutation in the para-type sodium channel gene (para), in the MR strain; however, the value of the MR strain for bifenthrin was 3,461-fold higher than that of the susceptible strain. Our results indicate that insecticide resistance is more effectively evaluated using molecular markers than by conducting a bioassay. The molecular markers StoF in ace1 and MtoL in para can easily be applied in diagnostic methods such as QS or PCR amplification of specific alleles (PASA). These methods may be extended to management of M. persicae resistance in the field.

Between 2010 and 2012, diseases and insect pests of sweet persimmon were surveyed at sweet persimmon export complexes and non-export orchards in Suncheon, Jeonnam Province; Jinju, Changwon (Dongeup and Bukmyeon), and Gimhae, Gyeongnam Province; and Ulzu, Ulsan. The following diseases were found in the sweet persimmon orchards: angular leaf spot (Cercospora kaki), anthracnose (Colletotrichum gloeosporioides and Colletotrichum acutatum), circular leaf spot (Mycosphaerella nawae), powdery mildew (Phyllactinia kakicola), and gray mold (Botrytis cinerea). Circular leaf spot was the most frequent and serious disease, and C. gloeosporioides and C. acutatum were found on fruits. Thirty-three insect pest species that belonged to 32 genera of 20 families in 5 orders were found in the sweet persimmon orchards; the two-spotted spider mite, Tetranychus urticae, was also found in the surveyed orchards. Apolygus spinolae, Pseudaulacaspis cockerelli, and Adoxophyes orana were widely found in the surveyed orchards; Spodoptera litura and Homona magnanima were also recorded. Damage by insect pests was low, and the quarantine insect pests peach pyralid moth (Dichocrocis punctiferalis) and persimmon fruit moth (Stathmopoda masinissa) were rarely or not found in the sweet persimmon export complexes. In addition, other quarantine insect pests, such as persimmon false spider mite (Tenuipalpus zhizhilashviliae) and Japanese mealybug (Planococcus kraunhiae), were not detected. These quarantine insect pests were also not found in the sorting places, storage houses, and fruits for export; however, scale insects and two-spotted spider mites were found at a low rate. Although anthracnose (C. acutatum) infested fruit was found in the storage houses, only one in Jinju and Gimhae.

The ussur brown katydid, Paratlanticus ussuriensis (Orthoptera: Tettigoniidae), causes substantial damage in orchard areas in South Korea. Daily rhythm and mating behaviors were investigated in last instar nymphs, immature adults and mature adults of P. ussuriensis. The daily rhythm was repeated upon resting, moving, and feeding. The daily rhythm of the movement behavior similar in both last instar nymphs and immature adults. Last instar nymphs becoming active at 10:06 and ceasing activity at 21:12 in average. Immature adults becoming active at 11:30 and ceasing activity at 20:08 in average of totally 10 individuals. However, mature adults showed a different active time of 15:30. Generally, behavior was affected by the conditions of their environment, especially temperature. Mature adults activated later than nymphs and immature adults. Mature adults display mating behavior at a particular time of day (approximately 20:00). P. ussuriensis showed a mating behavioral sequence which was similar to related species in completely retaining the spermatophylax. Females took 270 min to 360 min to completely retain the spermatophylax. The daily rhythm of P. ussuriensis, indicating its occurrence and ecology, could be useful as basic data for managing field populations of P. ussuriensis.

Corythucha marmorata (Uhler) belonging to the family Tingidae (Hemiptera) has been reported in Korea. In 2013, surveys were conducted to study its morphological characteristics, geographical distribution, and host plants. The adult is brown white and 2.77-3.28 mm in length, and the mature nymph is yellowish brown. Heavily infested trees appear yellowish white because they are fed on by the nymphs on the under surface of host plants. C. marmorata were found between early June and late October, and their numbers peaked in early July to late August. In 2013, the occurrence of C. marmorata was confirmed in 27 cities and counties nationwide, and 8 families and 24 species of host plants were identified. C. marmorata feeds on the following major host plants: Conyza canadensis, Aster pilosus, Helianthus annuus, Artemisia princeps, Rudbeckia bicolor, and Solanum melongena.

Transgenic crops that produce insecticidal toxins have a great potential for controlling target pest insects, but there is a growing concern about unintended influences on non-target species. In the present study, the preferences and performance of non-target green peach aphid, Myzus persicae (Sulzer), on transgenic cabbages (Brassica oleracea) that produce Bt toxin (Cry1Ac1) and untransformed control plants were investigated as a part of risk assessment. In a free-choice situation, the number of nymphs larviposited by 10 winged adults over 3 days was
on transgenic and the control plants, respectively, indicating that the aphids did not discriminate between the two types of plants. In a performance assay, the development time (D) and intrinsic rate of increase (rm) of wingless aphids reared on transgenic and control plants were also similar (D,
(days) and rm,
, for transgenic and control plants, respectively). These results suggest that M. persicae is not significantly affected by transgenic Bt cabbage.
