  • The external anatomy of the immature stages (last instar larva and pupa) of the crane fly, Tipula (Nippotipula) sinica Alexander, 1935 (Diptera: Tipulidae) is described and illustrated from specimens first collected in Korean peninsula (South Korea). Comments concerning natural history and microhabitats of larvae are provided. This is the first detailed description with illustrations for the last instar larva and pupa of Tipula (Nippotipula) sinica. Pupal characteristics resemble those of most species from advanced lineages within the subfamily Tipulinae. And, also it described with habitats and biological notes of Tipula (Nippotipula) sinica. Crane fly larvae, categorization as found in this survey indicate a taxonomic stream and are expected to help.

  • Morphological characteristics of nymphal instars are described for a Korean wood-feeding cockroach, Cryptocercus kyebangensis. Eleven instars, including adults, were tentatively identified. Female adults had apicolateral emargination and a truncated apical median prominence in the seventh sternite, and female nymphs of the other instars except for the last had a narrowly rounded apical median prominence in the seventh sternite. In the last instar, the seventh sternite was partially desclerotized and somewhat shriveled at the start of the emarginated area. In contrast, males showed no emargination in adults, and had a rounded broad apical median in this area of all instars. In the ninth sternite, female nymphs had a medium notch on the caudal margin and styli were separated before reaching adulthood, whereas no such notch was observed in male nymphs. The styli remained prominent in the ninth sternite of male adults.

  • The oriental tobacco budworm, Helicoverpa assulta (Lepidoptera: Noctuidae), is classified as a quarantine pest that must be controlled for the exportation of Korean paprika to the USA. We performed a confirmatory test of gamma irradiation against the last-instar larvae and pupae of H. assulta in paprika. Previous, small-scale gamma irradiation at a dose of 100 Gy to the last-instar larvae allowed emergence of adults, though they were abnormal, but 200 Gy prevented adult emergence completely. For pupae, irradiation of 5- to 6-day-old pupae with 300 Gy prevented normal emergence completely. To gather confirmatory data applicable to phytosanitary quarantine regulations, larvae and pupae were placed inside paprika in a box and were irradiated with 200 Gy and 300 Gy, respectively. After irradiation with 200 Gy (measured doses 170-199 Gy) of 2,186 individuals of the last-instar larvae, 10.84% survived, but either formed abnormal pupae (7.57%) or died during the pupal stage (3.27%), resulting in no emergence of normal adults. For pupae, the dose of 300 Gy (measured doses 276-319 Gy) given to 1,200 pupae allowed 10.75% to survive and 9.17% to emerge with deformity. However, 1.58% of irradiated pupae emerged normally, requiring an increased dose for complete prevention of normal emergence. Subsequently, an increased dose of 400 Gy (measured doses 340-402 Gy) to 1,005 pupae allowed 88.35% to emerge, but all emerged with deformity. Thus, irradiation treatment with a minimum dose of 400 Gy will provide quarantine security for all premature H. assulta in exported paprika.

  • 누에의 變態期 동안 貯藏蛋白質의 出現과 번데기 시기동안 각 組織에 따른 貯藏蛋白質의 分布를 살펴보기 위해 電氣泳動法, 免疫學的 方法 및 column chromatography法을 使用하였다. 혈림프의 貯藏蛋白質은 2개로 區分이 되었고, 5령 初期부터 出現하고 있으며 지방체 단백질과도 동일한 전기영동상의 移動度를 갖고 있다. 이의 量的 變化는 終令期에는 혈림프에서 높은 濃度를 유지하다.  化後에는 脂肪體에 축적이 되는 경향을 나타내며 특히 저장단백질-2가 암수에서 모두 두드러진 저장단백질의 양상을 보이고 있다. 이러한 貯藏蛋白質은 종령 末期에는 큐리클 단백질 형성에도 관여하는 것 같으며 번데기에는 中腸도 일시적으로 저장단백질을 저장하는 것 같다. 또한 貯藏蛋白質中 저장단백질-2는 vitellogenin과 정기영동 및 면역학적으로 동일한 이동도를 나타내고 있으며 특히 번데기시기동안 卵黃蛋白質의 항체에 대해 항원-항체반응을 나타내고 있어 卵形成過程에도 밀접하게 관여하는 것 같다.

  • 갈색여치는 최근 대발생으로 과수농가에서 피해가 급격히 증가하고 있다. 갈색여치의 종령 약충과 미성숙 성충, 성숙 성충에 대한 교미행동 및 일일행동패턴에 대하여 조사하였다. 일일행동패턴은 휴식, 이동, 섭식을 반복하였다. 종령 약충과 미성숙 성충의 일일행동패턴은 유사했다. 종령 약충은 평균 10:06에 활동을 시작하고 21:12에 휴식을 취한다. 미성숙 성충은 평균 11:30에 활동을 시작하고 20:08에 휴식을 취한다. 그러나 성숙 성충의 경우 15:30에 활동을 시작하는 차이를 보였다. 성숙 성충은 특정시간(약 20:00)대에 교미행동을 보인다. 갈색여치의 교미행동은 암컷의 spermatophylax를 섭취하게 되는데 다 섭취하기까지 270-360분이 소요된다. 갈색여치의 행동패턴은 이들의 발생양상과 생태를 알 수 있어 갈색여치를 방제하기 위한 기초자료로 이용될 수 있을 것이다.

  • The number of chromosomes of the wild mulberry silkworm, Bombyx mandarina, collected in Suwon area in the middle part of Korean peninsula was investigated. The chromosomes were examined after smearing and squashing the testis of the last instar larvae which were at spining stage and the microscopic observation showed that the number of chromosomes of the wild mulberry silkworm was 27.

  • Lipophorin (LP) was purified from hemolvmph of late last instar larvae of Hyphuntria cuneo D. by KBr density gradient ultracentrifugation. Chemical composition of LP was investigated by electrophoresis, thin laver chromatography and ryas chromatography. LP consisted of Apo-LP I and Apo-LP ll, and M.W. of them were 230 Kd and 80 Nd, respectivelv. Lipid of LP was mostly composed of neutral lipid including triacylglvcerol, diacvlslvcerol, monoacylglvcerol and free cholesterol, and phospholipid rich in phosphatidvlethanolamine and phosphatidvlcholine. Fatty acids present in these lipids were found to have be 14:0, 16:0, 18:1, and 20:1.
