Alydids and pentatomids are economic pests of leguminous crops and fruits in Korea. Direct impacts given by these phytophagous adult and nymphal by sucking on the pods, seeds and fruits can reduce germination potential of leguminous seeds, and yield poor nutritional quality. For monitoring of these bugs, various types of traps housing species-specific baiting with pheromones are widely practiced. However, a trap developed for one species has not been found to capture other species. Here, we developed a multi-species trapping device with some modification for enhancing capture efficacy of sympatric hemipteran bugs, called ‘rocket trap with solar fan’ pertaining to its shape. The trap with and without solar fan, and yellow, black, and white color stimuli were examined for the attractiveness of sympatric hemipteran bugs against conventional traps such as pyramid and fishnet traps. In addition, the attractiveness of single or mixed baits combination to sympatric hemipteran was also tested. Among the tested traps, yellowrocket trapwith solar fanwas found to attract significantly higher number of stink bug species. Major stink bugs, Riptortus pedestris, Halyomorpha halys, and Piezodorus hybneri were attracted to yellowrocket trapwith solar fan baitedwith aggregation pheromone of H. halys in the fields. The yellowrocket trap baitedwith aggregation pheromones alongwith food and synergistwas foundmore attractive to stink bugs. Results designate that yellow rocket trap with solar fan, and yellow rocket trap baited with mixed form of baits would have enhanced the monitoring and capturing sympatric hemipteran bugs in diversified agricultural landscapes.

배순도,이휘종,윤영남,장윤우,김용철,Rameswor MAHARJAN 한국응용곤충학회 2019 Journal of Asia-Pacific Entomology Vol.22 No.1

The stink bugs, Halyomorpha halys and Riptortus pedestris, are two of the most economically important pests of leguminous crops and fruits in Korea. Here we present the results from a field monitoring test that evaluated the effect of variation in rocket trap type and color on stink bugs captures. We tested various types of rocket traps, along with wing combinations and landing boards of various colors. The test was run in soybean fields in Miryang, Korea. We developed a modified rocket trap intended to enhance the capture efficacy of stink bugs. We evaluated traps including (1) yellow rocket trap with a solar fan and blue LED lamp, (2) a yellow trap with solar fan but no light, (3) rocket traps with black, green, yellow, white, red, brown, and blue color stimuli, (4) different color combinations of trap wings, and (5) traps with a landing board were evaluated. Our results showed that yellow winged rocket traps with solar fans and blue LED lamps attracted significantly more stink bug species than other traps, in both soybean fields. Use of these improved traps such as a yellow trap with a solar fan and blue LED lamp, and a yellow trap with a solar fan would therefore enhance the monitoring and capture of stink bugs in diversified agro-ecological landscapes. The potential use of traps with a specific hue, combination of features, and modifications to monitor stink bugs accurately is discussed. Continuing improvements to traps to meet the demands of a changing pest landscape and agricultural mechanization are needed.

배순도,최병렬,송유한,김현주 한국응용곤충학회 2003 한국응용곤충학회지 Vol.42 No.3

The susceptibility of the different larval stages of Spodoptera litura to nine insecticides was evaluated using the perilla leaf-dipping method. Median lethal concentration ($LC_{50}$) was increased with larval development in the range of 0.5 ppm to 5.6 ppm, 9.9 ppm to 27.9 ppm, 9.6 ppm to 125.1 ppm and 24.3 ppm to 546.6 ppm in the 1st, 2nd, 3rd and 4th instar, respectively. The tolerance ratio (TR), which is the TR of 90 percent lethal concentration (LC/ sub 90/) to the recommended concentration, was 0.04 to 0.8 in the 1 st, 0.2 to 7.5 in the 2nd, 0.7 to 115.3 in the 3rd and 1.2 to 485.4 in the 4th instars. Lower D$LC_{50}$ and DTR, which is the difference between the $LC_{50}$ and the TR of 4th and other instars, respectively, were observed in chlorfenapyr, chlorpyrifos and EPN while higher ones were lufenuron, chlorfluazuron and teflubenzuron. These results mean that insecticides with lower D$LC_{50}$ and DTR are effective in controlling larva of S. litura collected in Milyang, Korea. 밀양에서 채집한 담배거세미나방 유충의 약제감수성을 조사하였다. 약제의 반수치 사농도는 1령층에서 0.5-5.6ppm,2령층에서 9.9-27.9ppm, 3령층에서 9.6-125.1ppm 및 4령층에서 24.3-546.6ppm으로 약종에 따른 차이와 함께 유충의 영기가 증가할수록 높았다. 또한 약제별 추천농도에 대한 유충의 90%치사농도의 비로 나타낸 약제내성비(내성비=$LC_{90}$ 약제별 추천농도)도 1령충에서 0.04-0.8, 2령충에서 0.2-7.5, 3령충에서 0.7-115.3및 4령충 에서 1.2-483.4으로 약종에 따른 차이와 함께 유충의 영기가 증가할수록 높았다. 한편,동일 약제에서 유충의 영기간 반수치사농도, 및 내성비의 차이는 chlorfenapyr, chlorpyrifos 및 EPN에서 매우 낮았으며, lufenuron, chlorfluazuron및 teflubenzuron에서 매우 높았다. 이러한 결과를 종합하면 담배거세미나방 유충의 방제는 영기가 어릴수록 또한 약제감수성이 낮은 약제, 즉 반수치사농도 및 내성비의 차이가 적은 약제인 chlorfenapyr, chlorpyrifos 및 EPN을 사용할수록 효과적임을 의미한다.

배순도,김현주,홍연규,조현제 한국응용곤충학회 2004 한국응용곤충학회지 Vol.43 No.2

담배거세미나방의 유충에 처리된 살충제의 아치사농도($LC_{10}$ 및 $LC_{30}$)가 용발육, 성충수명 및 산란에 미치는 영향을 조사하였다. 용기간은 무처리의 암컷과 수컷에서 각각 6.9일과 8.0일, 살충제 처리에서 각각 7.2-7.6일과 8.3-8.6일로 무처리보다 살충제 처리에서 길었으나 살충제의 종류 및 아치사농도에 따른 유의한 차이는 없었다. 우화율은 무처리에서 88%, 살충제 처리에서 약 79-95%로 약제처리유무 및 아치사농도 처리에간 뚜렷한 경향이 없었으며, 특히 chlo.fenapyr-bifenthrin 및 ethofenprox처리에서 91.0% 이상의 높은 우화율을 나타내었다. 성충수명은 무처리의 암컷과 수컷에서 각각 7.7일과 7.9일, 살충제 처리에서 각각 7.1-8.4일과 7.7-9.0일로 hexaflumuron-chlorpyrifos의 $LC_{30}$처리에서 가장 길었던 것을 제외하면, 살충제 처리유무 및 농도에 따른 유의한 차이는 없었다. 총 산란수는 무처리에서 1,010개, 살충제 처리에서 778-948개로 살충제 처리유무에 따른 차이는 있었으나, 살충제의 종류 및 농도에 따른 유의한 차이는 없었다. 따라서 담배거세미나방의 용기간 및 산란은 유충에 처리된 살충제의 아치사농도처리에 의해 영향을 받았다. This study was conducted to determine the effect of sublethal concentrations ($LC_{10}$ and $LC_{30}$) of insecticides on pupal duration, emergence, adult longevity and oviposition of tobacco cutworm, Spodoptera litura Fabricius, when 3rd instar larva of tobacco cutworm was treated with insecticides of chlorpyrifos, ethofenprox, chlorfenapyr-bifenthrin and hexaflumuron-chlorpyrifos . Pupal duration of female and male were 6.9 days and 8.0 days at untreatment, and were 7.2 to 7.6 days and 8.3 to 8.6 days at insecticide treatment, respectively. Thus pupal duration at the insecticide treatment was slightly longer than that at the untreatment, and that of the males was slightly longer than that of the females even though significant difference between sublethal concentrations and among insecticides was not observed. Percent mergence was 88% at untreatment and ranged from 79% to 95%, in particular which showed above 91% treated with chlorfenapyr-bifenthrin and ethofenprox, at insecticide treatment. Adult longevity was 7.7 days and 7.9 days for female and male at untreatment respectively, and 7.1 to 8.4 days for female and 7.7 days to 9.0 days for male at treatment. There was a significant difference between insecticides and sublethal concentrations of insecticides except showed the longest adult longevity at hexaflumuron-chlolfyrifos treatment. Total number of eggs laid were less at treatment (778-948) than that (1,010) at untreatment regardless of sublethal concentrations of insecticides. Accordingly the pupal duration and oviposition of tobacco cutworm were affected at the insecticide treatment of sublethal concentration.

배순도,김현주,박정규,정진교,Bae Soon-Do,Kim Hyun-Ju,Park Chung-Gyoo,Jung Jin-Kyo 한국응용곤충학회 2004 한국응용곤충학회지 Vol.43 No.4

망사시험관 및 유리시험관에서 톱다리개미허리노린재의 약충발육, 성충수명 및 산란수를 비교하였다. 약충기간은 유리시험관(20일)보다 망사시험관(약 21일)에서 약 1일 길었는데, 이러한 차이는 주로 5령충의 발육기간에 기인되었다. 우화율은 유리시험관($56\%$)보다 망사시험관($64\%$)에서 $8\%$높았다. 성충수명은 유리시험관보다 망사시험관에서 암컷이 약 4.1배, 수컷이 약 6배 길었다. 산란전기간은 유리시험관보다 망사시험관에서 약 1일 길었으며, 산란수는 유리시험관보다 망사시험관에서 약 3.5배 많았다. 산란지속기간은 망사 시험관에서 약 30일, 유리시험관에서 약 8일 이었다. 따라서 톱다리개미허리 노린재의 발육특성을 정확하게 구명하기 위해선 공기유통이 원활한 망사시험관을 사용하는 것이 적합할 것으로 판단되었다. This study compared the biological characteristics, nymphal development, adult longevity, and oviposition of the bean bug, Riptortus clavatus Thunberg, in fibrous nylon and glass-tube in the insectary at $28{\pm}2^{\circ}C$ and 16L:8D of photoperiod. Nymphal duration in the fibrous nylon-tube was 1 day longer than in the glass tube; the difference was attributed to the developmental duration of the fifth instar. Percent emergence in the fibrous nylon-tube was $64\%,\;8\%$ higher than in the glass tube ($56\%$). In the fibrous nylon-tube, adult longevities for female and male were 4.1 times and 6.0 times higher than those in the glass tube. Preoviposition period was 1 day longer in the fibrous nylon-tube than that in the glass tube. The total number of eggs laid was 3.5 times more in the fibrous nylon-tube than in the glass tube. The oviposition duration lasted about 30 days for the bean bug in the fibrous nylon-tube and about 8 days for those in the glass. Accordingly, the fibrous nylon-tube was found more conducive than the glass tube for determining the biology of bean bug.

배순도,김현주,이건휘,박성태,Bae, Soon-Do,Kim, Hyun-Ju,Lee, Geon-Hwi,Park, Sung-Tae 한국응용곤충학회 2008 한국응용곤충학회지 Vol.47 No.1

규격이 다른 5가지 사육용기, A용기(원통형, 직경 10cm, 높이 4cm), B용기(원통형, 직경 14.5cm, 높이 2.8cm), C용기(사각통, 가로${\times}$세로=$6.5{\times}6.5cm$, 높이 10cm), D용기(원통형, 밑지름 9cm 윗지름 11.5 cm, 높이 10.8 cm), E용기(원통형, 직경 15cm, 높이 7.5 cm)에 두류종자(대두 + 땅콩종자) 및 스폰지 급수통을 제공하여 $24^{\circ}C$, 15L : 9D 실내조건에서 풀색노린재의 부화율, 우화율 및 산란수를 조사하여 증식률을 구하였다. 부화율은 93-97%이었다. 영기별 발육기간은 1령에서 6일로 가장 짧았으며, 5령에서 약 10일로 가장 길었다. 약충기간은 38-39일 및 우화율은 53-62%로 용기에 따른 차이가 있었다. 성충수명은 수컷에서 65-75일, 암컷에서 67-74일이었고, 성별에 관계없이 B용기에서 가장 길었다. 암컷의 산란수는 51-56개로 B용기에서 가장 많았고, E용기에서 가장 적었다. 따라서 풀색노린재의 1세대 증식률은 약 25-33배로 사육용기에 따른 차이와 함께 B용기에서 가장 높았다. 그러므로 B용기는 실내에서 풀색노린재를 가장 안정적으로 사육할 수 있는 용기로 여겨졌다. The embryonic and postembryonic developments of Nezara antennata Scott were observed in 5 different rearing cages such as A (Cylindrical, ${\phi}\;10cm{\times}4cm$), B (Cylindrical, ${\phi}\;14.5cm{\times}2.8cm$), C (Rectangle, $6.5L{\times}6.5cmW{\times}10cmH$), D (Cylindrical, ${\phi}$ 9cm in bottom & ${\phi}$ 11.5 cm in $upper{\times}10.8cm$) and E (Cylindrical, ${\phi}\;15cm{\times}7.5cm$) containing soybean and peanut seeds as food, and sponge soaked with water under laboratory condition of $24^{\circ}C$ and 15L : 9D. Hatchability ranged from 93 to 97%. Nymphal duration was shortest of 6 days in the 1st instar and longest of 10 days in the 5th instar. The nymphal duration was 38 to 39 days observed in the rearing cages. Emergence rate was in the range from 53 to 62% with highest in A and B cages. Adult longevity was 65 to 75 days for male, and 67 to 74 days for female, and was longest in the B cage. Total number of eggs laid by female adult was in the range from 51 to 56 without significant difference in the rearing cages, and was the most in the B cage. Accordingly, the reproductive rate of N. antennata for 1 generation was within 25 to 33 times, and was highest in the B rearing cage. Therefore, it could be concluded that B cage is most suitable for stable rearing of N. antennata under laboratory condition.

배순도,김현주,박정규,이건휘,박성태,송유한,Bae, Soon-Do,Kim, Hyun-Ju,Park, Chung-Gyoo,Lee, Geon-Hwi,Park, Sung-Tae,Song, Yoo-Han 한국응용곤충학회 2005 한국응용곤충학회지 Vol.44 No.4

규격이 다른 5가지 사육용기, A용기 (원통형, 직경 10 cm, 높이 4 cm), B용기 (원통형, 지름 14.5 cm, 높이 2.8 cm), C용기 (사각통, 가로${\times}$세로 : $6.5{\times}6.5cm$, 높이 10 cm), D용기 (원통형, 밑지름 9 cm, 밑지름 11.5 cm,높이 10.8 cm), E용기 (원통형, 직경 15 cm, 높이 7.5 cm)에 두류종자 (대두+땅 콩종자) 및 스폰지급수물을 제공하여 $24^{\circ}C$, 16L:8D 실내조건에서 가로줄노린재의 부화율, 우화율 및 산란수를 조사하여 증식율을 구하였다. 난기간은 사육용기에 관계없이 6일 이었다. 부화율은 $63{\sim}80%$로 B용기에서 가장 높았다. 영기별 발육기간은 1령에서 5일, 5령에서 11일로 영기가 증가할수록 현저히 증가하였다. 약충기간은 $35{\sim}36$일로 사육용기에 따른 현저한 차이는 없었다. 우화을은 $65{\sim}82%$로 B용기에서 가장 높았으며, 다음은 A용기 였다. 성충수명은 수컷에서 $35{\sim}83$일, 암컷에서 $32{\sim}79$일 이었고, 성별에 관계없이 B용기에서 가장 길었다. 암컷의 산란수는 $38{\sim}86$개로 사육용기에 따라 현저한 차이가 있었으며, B용기에서 가장 많았고, E용기에서 가장 적었다. 따라서 가로줄노린재의 1세대 증식율은 약 $17{\sim}56$배로 사육용기에 따른 현저한 차이와 함께 B용기에서 가장 높았다. 그러므로 실내에서 가로줄노린재를 가장 안정적으로 사육하기 위해선 B용기를 이용하는 것이 가장 효과적인 것으로 나타났다. The embryonic and postembryonic developments of Pierodorus hybneri Linnaeus were observed in 5 different rearing cages such as A (Cylindrical, 10 cm in diameter, height of 4 cm), B (Cylindrical, 14.5 cm in diameter, height of 2.8 cm), C (Rectangle, 6.5 by 6.5 cm in $length{\times}breadth$, height of 10 cm), D (Cylindrical, 9 cm in bottom diameter, 11.5 cm in upper diameter, height of 10.8 cm) and E (Cylindrical, 15 cm in diameter, height of 7.5 cm) containing soybean and peanut seeds as feeding food, and sponge-water container under laboratory condition of $24^{\circ}C$ and 16L:8D. Egg duration was 6 days regardless of rearing cages. Hatchability ranged from 63 to 80% with the highest in B (14.5 cm in diameter, 2.8 cm in height) rearing cage. Instar duration was longer from 5 days in 1st instar to about 11 days in 5th instar. Nymphal duration showed 35 to 36 days with'3ut significant difference in rearing cages. Percent emergence was in range from 65 to 82% with the highest in B rearing cage. Adult longevity was 35 to 83 days for male, and 32 to 79 days for female, and was the longest in B rearing cage. Total number of eggs laid by female adult was in range from 38 to 86 with significant difference in rearing cages, and was the most in B rearing cage. Accordingly, the reproductive rate of P. hybneri for 1 generation was within 17 to 56 times, and was the highest in B rearing cage. Therefore, it could be concluded that B cage is most suitable for stable rearing of P. hybneri under laboratory condition.

영남지방의 지역 및 기후지대별 담배거세미나방과 파밤나방의 발생소장을 각각의 성페로몬을 이용하여 조사하였다. 경람지역에서 담배거세미나방은 3월 중하순부터 11월 중하순까지 발생하였다. 경북지역에서 담배거세미나방은 4월 중하순부터 11월 상중순까지 발생하였으나, 울진에선 5월 하순부터 10월 하순까지 발생하였다. 기후지대별 담배거세미나방의 발생최성기는 남부해안지대에서 9월 중순, 내륙지대 및 분지지대에서 8월 하순, 내륙산간지대에서 8월 중순, 그리고 동해안중부지대에서 9월 상순이었다. 담배거세미나방의 지역별 발생비율은 경남의 경우 진주에서 20.0%로 가장 높았으며, 창녕에서 8.6%로 가장 낮았고, 경북의 경우 성주에서 3.3%로 가장 높았으며, 울진에서 0.8%로 가장 낮았다. 기후지대별 발생비율은 내륙지대에서 43.7%로 가장 높았으며, 다음은 남부해안지대에서 36.3%, 분지지대에서 8.4%, 내륙산간지대에서 7.0%이었고, 동해안중부지대에서 4.6%로 가장 낮았다. 한편, 파밤나방은 경북의 동해안중부지대를 제외하곤 3월 상순부터 11월 중순까지 발생하였다. 포항, 영덕 및 울진의 동해안중부지대에서 파밤나방은 대체로 4월 중순부터 11월 중순까지 발생하였다. 기후지 대별 파밤나방의 발생최성기는 내륙지대, 분지지대 및 내륙산간지대에서 8월 상순, 남부해안지대 및 동해안중부지대에서 8월 하순이었다. 파밤나방의 지역별 발생비율은 경남의 경우 창녕에서 1.6%로 가장 높았으며, 부산에서 0.4%로 가장 낮았고, 경북의 경우 성주에서 37.2%로 가장 높았으며, 울진에서 2.7%로 가장 낮았다. 기후지대별 발생비율은 분지지대에서 약 54.3%로 가장 많았으며, 다음은 내륙산간지대에서 29.9%, 동해안중부지대에서 9.3%, 내륙지대에서 3.9%이었고, 남부해안지대에서 2.6%로 가장 낮았다. 따라서 담배거세미나방은 경남지방에서, 파밤나방은 경북지방에서 다발생 되었고, 기후지대별 담배거세미나방의 발생량은 경남의 내륙지대, 파밤나방의 발생량은 경북의 분지지대에서 가장 많았다. 영남지방에서 담배거세미나방의 발생량은 파밤나방보다 2.4배 많았으나, 최초 발생시기와 발생최성기는 담배거세 미나방보다 파밤나방이 약간 빨랐다. Seasonal occurrences of tobacco cutworm, Spodoptera litura and beet armyworm, Spodoptera exigua were observed using sex pheromone traps at different locations and climatic regions in Yeongnam district. In Gyeongnam province, S. litura male adults kept occur from mid or late March to mid or late November Whereas in Gyeongbuk province, S. litura occurred from mid or late April to early or mid November with exception at Uljin where it was late May to late October. According to the climatic regions, the peak occurrence of S. litura was middle September at the southern coast region, late August at the inland and the basin region, middle August at the inland mountainous region, and early September at the eastern middle coast region. The occurrence rate of S. litura was the highest at Jinju with 20.0% and the lowest at Changyeong with 8.6% in Cyeongnam province, while it was the highest at Sungju with 3.3% and the lowest at Uljin with 0.8% in Gyeongbuk province. In accordance with the climatic regions, the occurrence rate of S. litura was the highest at the inland region with 43.7%, and followed by the southern coast region (36.3%), the basin region (8.4%) and the inland mountainous region (7.0%), and was the lowest at the eastern middle coast legion with 4.6%. On the other hand, S. exigua occurred from early March to middle November with the exception of the eastern middle coast region including Pohang, Yeongdeog and U]ien in Cyeongbuk province where it occurred from mfd April to middle November. The peak occurrence of s. exigua was early August at the inland region, the basin region and the inland mountainous region, and was late of August at the southern coast region and the eastern middle coast region. The occurrence of S. exigua was the highest at Changyeong with 1.6% and the lowest at Busan with 0.4% in Gyeongnam province, while it was the highest at Sungju with 37.2% and the lowest at Uljin with 2.7% in Gyeongbuk province. The climatic regional occurrence rate of S. exigua was the highest at the basin region with 54.3%, and followed by the inland mountainous region (29.9%), the eastern middle coast region (9.3%) and the inland (3.9%), and was the lowest at the southern coast region with 2.6%. As a whole, S. litura occurred more in Gyeongnam province than Cyeongbuk province, while S. exigua occurred more in Gyeongbuk province than Gyeongnam province. According to the regions grouped by climatic differences, the occurrence of S. litura and S. exigua was the highest at the inland region in Gyeongnam province and at the basin region in Gyeongbuk province. The total number of S. litura captured by sex pheromone trap was 2.4 times higher than that of S. exigua. However, the first occurring time and the peak occurrence of S. exigua were slightly earlier than those of S. litura.
