  • A new species of scale insect, Matsutoctus thunbergianae Miller and Park, is described using life history information and morphological characteristics of adult female, adult male, third instar male, and first instar. The species is morphologically similar to M. matsumurae (Kuwana) and M. resinosae Bean and Godwin; the most obvious structural differences are found in the adult male. The species is univoltine and overwinters as second instars, whereas M. matsumurae and M. resinosae are bivoltine and overwinter as first instars. Information is given supporting evidence that the same instar of different generations of multivoltine species differ significantly morphologically.

  • 최근 환경변화와 국제교류의 확대로 인하여 예전에는 문제가 되지 않았거나, 보이지 않았던 해충들이 문제해충화 되어 우리 주변에서 정원수나 조경수에 피해를 주는 해충들이 있다. 이들은 크게 3가지로 분류되는데 (1)환경의 변화에 의한 잠재해충과 문제해충화 (2) 인간의 욕심에 의해 대면적 식재로 인한 해충의 기회 확대 (3) 국제교류 확대로 인한 외래 해충의 침입 으로 나눌 수 있다. 이번 호에서는 환경변화에 의한 해충의 발생으로 환경스트레스에 의해 식물 자체 내의 방어체계가 무너지면 어떤 특정종이나 일반 해충이 대발생하는데 식물자체 환경 스트레스에 관계하는 jasmonate의 작용 저해, 식물이 자기방어를 위해 분비하는 타감물질(allelopathy)의 분비 억제, 초식성 곤충으로부터 산란억제를 위한 연모의 부족 등 해충의 대발생을 야기 시키는 경우도 있다. 또한 지구온난화로 인한 각종 해충의 대발생은 현재 전 세계적으로 문제가 되고 있다. 기온의 상승으로 곤충의 발육이 빨라져 화기 수가 증가한다거나, 포식자와 피식자의 상호작용의 연결고리가 깨어지는 등 각종 원인으로 인한 최근 발생한 해충을 기술하였다.

  • 자연의 세계에서 나뭇잎, 돌기물, 구름, 해안선, 곤충의 모습 등에 내재하고 있는 아름다움은 흔히 균형성, 대칭성, 다양성 등으로부터 비롯된다. 자연 현상은 복소수를 활용하여 극좌표 표현으로 묘사되는 경우가 많다. 본 논문에서는 1989년 Temple H. Fay가 Amer. Math. Monthly 96(5)호에서 발표한 나비곡선 $r=e^{cos{\theta}}-2cos4{\theta}+sin^5(\frac{\theta}{12})$의 기하학적 성질을 분석하고, 수학전문 소프트웨어인 매스매티카를 활용하여 나비곡선의 작도하고자 한다.

  • The European pepper moth, Duponchelia fovealis Zeller (Lepidoptera: Crambidae) was discovered at Gyeonggi-do, Korea in 2015 and 2016. The moth has been known as a very harmful pest of ornamental plants worldwide. Larval damages to the Euphorbia milii stems and to the Schlumbergera truncata leaves were detected. After immediate spraying of insecticides, the moth was not found at the greenhouse any more.

  • A cosmopterigid species, Alloclita mongolica Sinev is reported for the first time from Korea. This is the first record of the genus Alloclita Staudinger for the Korean fauna and the southernmost records of A. mongolica. The collecting data of the species in Korea suggest a habitat association of A. mongolica with coastal sand-dunes. The features of external appearance and male genitalia are described and illustrated for this rare species.

  • The optimal synthetic medium, temperature and pH range for the mycelial growth of Cordyceps scarabaeicola were PDA, $25^{\circ}C$, and pH $8.0{\sim}8.5$, respectively. The effects of carbon sources, nitrogen sources and mineral salts on mycelial growth were superior to lactose, ammonium phosphate and $CaCl_2$, respectively. Liquid spawn culture was selected out BM(brown sugar 3%, soybean flour 0.3%, potassium phosphate 0.05%, magnesium sulfate 0.05%) medium.

  • Purpose: This study aims to evaluate the recognition, purchase, and intake status of edible insects in adults, who are the main consumers of edible insects, and to provide the information necessary to expand the production and consumption of edible insects and related products in the future. Methods: A total of 453 adults (172 males and 281 females) aged 19 years and older were surveyed regarding their awareness of edible insects, purchase and consumption experience, and intention to purchase and consume, and the differences between them were analyzed according to gender and age groups. Data collection took place from December 2018 to January 2019. Results: Those who had knowledge of edible insects accounted for 87.0%, whereas those who had more than average knowledge were 75.9%, suggesting recognition was relatively high. Men had more experience than women in purchasing or consuming edible insects and related products (45.9% vs. 31.0%, p < 0.01). In terms of age, experience was 22.5% in 20-30s, 44.6% in 40-50s, and 63.1% in 60s and older, showing significant growth as age increased (p < 0.001). The satisfaction level of edible insects was highest in taste (3.4 points), and especially for shape and appearance, it decreased as age reduced (p < 0.001). The most common reason for not being willing to use edible insects was feeling repulsive (4.1 points), which was significantly more common in women than in men (4.3 vs. 3.9, p < 0.001), and lower with age (p < 0.001). The most needed information display for using edible insects was country of origin (63.8%), the main nutrient in edible insects was protein (93.6%), and the most preferred form of products was powder (39.5%). Conclusion: According to the above results, the recognition of edible insects was high, whereas experience of using edible insects and intention to use edible insects were low especially in women and younger groups. The reason for this is that consumers are dissatisfied with edible insects due to their appearance. This study is expected to be used as basic data for expanding the production and consumption of edible insects and related products in the future.
