  • 꽃매미는 1932년 일본의 곤충분류 학자 Doi에 의해 꽃매미(Lycorma delicatula(White, 1845)와 희조꽃매미(Limois Emelianovi Oshanin, 1980) 2종이 보고된 바 있다. 이는 1979년에 발간된 한국동식물도감(문교부)에 있지만 그 동안 표본이 채집되지 않아 한국곤충명집(한국응용곤충학회, 한국곤충학회, 1994)에서 Lycorma delicatula는 제외 시키고 Limois emelianovi 1종만을 꽃매미로 기록하였다. 하지만 2008년 한정민 등 6인 분류학자에 의해 이 종에 대한 형택�F걱 특징과 Cytochrome Oxidase 1 (CO 1)분석을 통해 이종을 꽃매미로 Limois emelianovi를 희조꽃매미로 재분류 보고하여 그동안 주홍날개꽃매미로 불려지던 Lycorma delicatula는 꽃매미로 부르는 것으로 결론났다. 본 해충 꽃매미는 도시 내 조경수 공원 가로수 등에 식재되는 다양한 활엽수에 피해를 주며, 특히 사람들에게 혐오감을 유발하므로 이에 대한 생태 형태와 간략한 방제방법을 소개하고자 한다.

  • Morphometric analysis of Lycorma delicatula was performed to confirm whether local individuals had a geographical difference in their wing variations. The L. delicatula individuals were collected from 10 localities in Korea, China, and Japan, and 14 morphometric characteristics selected from the forewing were analyzed. The Korean individuals were similar to the ones from the northern area of the Yangtze River, but less similar to the others from the southern area of the Yangtze River. The individuals from Seoul and Buan were very similar to those from Shanghai. In case of wing spots, the individuals from Beijing had relatively small spots, while the ones from Linan had big spots. The Japanese individuals had a relatively large wing size.

  • Lantern fly(Lycorma delicatula) is a major invasive pest that causes withering symptom of agricultural crops by sucking tree sap and sooty mold symptom by producing honeydew. This study was conducted to investigate the occurrence pattern of lantern fly in grape orchards in Gyeonggi area and the effect of winter temperature on L. delicatula egg survival during 2010 to 2013. In Gyeonggi areas, overwintered L. delicatula eggs began to hatch from early May and nymphs peaked in mid May. Adults emerged from late July and laid eggs until early November. The survival of L. delicatula eggs during overwintering was largely affected by winter temperatures. The relationship between the number of days below a threshold temperature (x) in January and the survival rate of overwintering L. delicatula eggs (y) was using linear regression model. The best model selected by the lowest RSS (residual sum of square) between predicted and actual survival was y = -1.0486 x + 94.496 ($R^2=0.7067$) with $-11^{\circ}C$ of threshold temperature. These results should be helpful to conduct L. delicatula management programs, since the results provided relivable prediction for the winter survival of L. delicatula eggs and the phenology of egg hatch in the spring.

  • Eggs, immature eggs, and pupae of 8 different insects (Halyomopha halys, Riptortus pedestris, Lymantria dispar, Antheraea yamamai, Verlarifictorus spp, Antheraea pernyi, and Musca domestica) including Lycorma delicatura were used to select the alternative host for laboratory mass rearing of A. orientalis. Except L. delicatula's eggs and immature eggs of A. pernyi, other 7 tested insects were not parasitized by A. orientalis. A. pernyi was reared with oak tree leaves and its cocoons were harvested on mid-July and early October. On 4 or 5 days after emergence, only female adults showing swollen abdomen were collected and stored at $1{\sim}5^{\circ}C$. We could get 150~200 eggs per one female by dissecting the female's abdomen. For examining the possibility for laboratory mass rearing of A. orientalis with A. pernyi's immature eggs, developmental periods from egg to pupa between the two different hosts were compared. Developmental periods were 36.1 days on immature eggs of A. pernyi and 36.8 days on an original host's eggs, respectively. The number of parasitized eggs by A. orientalis' female for 24 h was 3.4 on immature eggs of A. pernyi and 4.2 on an original host's eggs, respectively. However, there were no significant statistical differences in developmental period and parasitization between the two hosts. By supplying honeyed water to newly emerged female parasitoids, it was able to maximize their longevities up to 64.3 days after emergence. Therefore, our results support potential for laboratory mass-rearing of A. orientalis using A. pernyi's immature eggs as an alternative host.

  • This study was performed to investigate the hatching rate and eggs period until hatching in the laboratory against lantern fly, Lycorma delicatula eggs with different collecting date of eggs, and the susceptibility of 26 insecticides to the eggs, 1st and 2nd nymphs of Lycorma delicatula. The eggs of L. delicatula were increased the hatching rates as passed collecting date of eggs, and shorten in eggs period until hatching. By screening the susceptibility of 26 insecticides to the eggs, 1st, and 2nd nymphs, chlorpyrifos (312.5 ppm) showed the perfect inhibition effect of hatching against the eggs, however, the other insecticides did not show that effect. According to the collecting date of eggs, chlorpyrifos bioassayed the inecticidal effect with different concentration (625 ppm at double conc., 312.5 ppm at recommended conc., and 156.3 ppm at half conc.). The eggs collected from Apr. 20th 2010, were showed the inhibition effect of hatching over 94.5%, but the eggs collected from May 10th, 2010 were showed the inhibition effect of hatching as 86.7, 71.1, and 47.1%, respectively. However, hatched eggs were all killed perfectly within 24 hours. At recommended and half concentrations, the eggs collected from 15, May, are decreased the effect as 48.6%, 53.7%, respectively, and the mortality of eggs hatched also decreased as 61.0 and 22.0%, respectively, however, double concentrations did not show the changes. From the above results, it will be anticipate to show the higher mortality against the eggs of L. delicatula when treated chlorpyrifos until late-April.

  • Anastatus orientalis Yang et Gibson(Hymenoptera : Eupelmidae) is the egg parasitoid of lantern-fly Lycorma delicatula. The natural parasitism showed that: (1)the highest parasitism rate of egg masses was 68.96% in Yantai Shandong; (2)the highest parasitism rate of eggs was 32.98% in Haidian Beijing; (3)the eggs of parasitoids hatched and emerged earliest in Yangling Shaanxi; emergence time of different populations in Yantai, Guangang Tianjin, Qinhuangdao Hebei and Haidian was similar; (4) the sex ratios were various among the populations ranging from 1.92 to 1.94; (5) parasitism rates of egg masses on Populus sp., Salix sp. and Toona sinensis were not significantly different, the highest parasitism rate of egg masses was 64.3% on T. sinensis, and the lowest rate was 27.4% on Ailanthus altissima; (6)parasitism rates of eggs on Populus sp., Salix sp., T. sinensis and A. altissima were not significantly different, about 30% averagely.

  • This study was conducted to predict the hatching time of eggs of Lycorma delicatula, to select an effective environmentally-friendly agriculture material (EFAM) and to evaluate the attraction effect of brown sticky traps for controling of Lycorma delicatula nymph and adults. Eggs hatched 55.9, 26.8, 21.6 days after incubation at 15, 20, $25^{\circ}C$ with 14L:10D condition and the hatching rates of egg were 61.9, 57.8, 30.4%, respectively. At high temperature conditions, egg development periods were shorter and the hatching rate was lower. The relationship between temperature and developmental rate was expressed by the linear equation Y=0.0028X-0.0228, $R^2$=0.9561. The low temperature threshold of eggs was $8.14^{\circ}C$ and the thermal constant required to reach larva was 355.4 DD. According to this relationship, the mean estimated hatching date was $22^{nd}$ May. The effective EFAM was natural plant extract, sophora extract, derris extract to nymph and natural plant extract, pyrethrum extract, sophora extract to adult. Among three colors of sticky trap : brown, blue and yellow, the brown sticky trap was the most attractive to nymphs and adults of L. delicatula over a 2 weeks trial period. It suggested that the brown sticky trap could be a very useful and environment-friendly control method for nymphs and adults of L. delicatula.

  • 최근 기후변화 개방화로 산림과 농경지 모두가 서식처인 외래종 꽃매미, 미국선녀벌레, 갈색날개매미충 등의 새로운 해충이 돌발적으로 발생하여 그 피해가 심각해지고 있다. 이 해충들은 흡즙성의 가해양상을 보이며 알로 월동하고 생활사가 유사하며 기주범위가 상당히 넓다는 공통적인 특징을 지니고 있다. 꽃매미의 유입 정착사례에서 보듯이 최근의 기후변화가 발생과 관련되어 있어 앞으로 수목과 농작물 모두에 피해가 우려되고 있는 실정이다. 특히 최근 온화한 겨울 기온과 봄철 이상기온으로 인해 알로 월동하는 해충들의 월동치사율이 감소하고 발생시기가 빨라질 것으로 예측되는 상황에서 이들 문제 해충의 생태 및 방제법에 대하여 간단히 소개하고자 한다.
