Mulberry leaf roller, Diaphania pulverulentalis (Hampson), is a major pest of mulberry, Morus alba. The life table construction from present investigation reveals the age specific survival $(1_{x)}$ and the age specific fecundity $(m_{x})$ of the pest. The female contributed the highest egg production $(m_{x} ＝ 12.75)4 in the life cycle on the $27^{th}$ day and the lowest $(m_{x} = 0.8)$ on the 37$^{th}$ day of the pivotal age. The female progeny production was observed to be intensive for the first six days after the preoviposition period, beyond which it declines steadily, The fecundity of D. pulverulentalis varies between 60-140. The first female mortality within the cohort occurred 4 days after the adult emergence and mortality increased thereafter, One generation is completed in 33.08 days. The female dominated sex ratio (1: 7.18 days) was recorded.

Langerhans cell histiocytosis (LCH) is generally considered a childhood disease that exhibits various nonspecific clinical and radiological manifestations that mimic infection or malignancy. Here, we present a case of LCH involving the rib in an adult patient. CT and MRI revealed an expansile lytic lesion with periosteal reaction on the left 8th rib, suggesting a malignant bone tumor. Surgical resection was performed and histopathological examination was consistent with LCH. Owing to its rare occurrence in adults and nonspecific aggressive features, LCH should be included in the differential diagnosis of an aggressive-appearing rib lesion in both adults and children.

The authors made a clinical study of 107 cases of empyema who were treated at Department of Thoracic Surgery of Chungnam National University Hospital during the period of Jan. 1976 through Aug. 1982 and compared the empyema of infant and children with that of adults. Following was the remits: 1. Male was predominant to female with the ratio of 2.5 to 1 and adult to infant was 2.6 to 1. 2. The cardinal symptoms were dyspnea, coughing, chest pain and fever. 3. Positive remit of bacteriological culture study was reported in 57% and the most common causative organism was staphylococcus in infant and childhood, E. coil in adult. 4. Most frequent predisposing factors of thoracic empyema in infant and childhood was pneumonia [53%], and in adult was pulmonary tuberculosis [40%]. 5. Treatment were combined with antibiotics therapy and several surgical procedures for empyema. 24 cases [22.4%] required open thoracotomy. 6. The mortality rate was 7.4% [8/107]. 86 cases [80.4%] were discharged with recovery and improvement.

A 3-yr-old female mongrel dog was referred to the Veterinary Teaching Hospital of Chungnam National University in the Republic of Korea. An adult heartworm, Dirofilaria immitis, was found in the abdominal cavity of the dog during spaying. Dirofilariasis in this dog was also diagnosed by modified Knott's test, ELISA test, and PCR analysis. The present case is the first report on the migration of an adult dog heartworm to the abdominal cavity of a dog in the Republic of Korea.

A gregarious pupal endoparasitoid Tetrastichsus sp. (Hymenoptera: Eulophidae) was reared in vitro from oviposition to adult emergence on an artificial host. The host pupal case was made using 0.02 mm-thick polypropylene film, and was filled with a diet consisting of powders of Antheraea pernyi pupa, chicken yolk, infant formula, royal jelly, and Neisenheimer's salt solution. Female parasitoids reared in the artificial host produced smaller sized progeny than those reared in in vivo, but the adults reproduced fertile offsprings. Furthermore in vitro second-generation (G$_2$) females showed more improved biological characteristics, compared with their parents. The fecundity (mean no. adult progeny), oviposition period (days), and longevity (days) of G$_2$ female were evaluated as 45.7, 7.8, and 13.8, respectively Female biased sex ratio was obtained with 76.9% female progeny. The results demonstrated that Tetrastichus sp. is a promising parasitoid for in vitro mass production.

Stability of resistance of the two-spotted spider mite (Tetranychus urticae) to dicofol was investigated. Resistance level (23.0-fold) of adult females to dicofol was kept up to 1 year without selection by dicofol, but was decreased to 15.8-, 10.7-fold after 2 and 3 years, respectively. Susceptibility of adult females obtained from reciprocal crosses $(R_{female}\timesS_{male},R_{male}\times S_{female})$ of the R and S stains to dicofol was declined by the success of generation.

Objectives : Osteoporosis is the most common metabolic disease of the bone, and one of the most important public health problems around the world. Obesity rate gradually increases as women grow older. The purpose of the study was to investigate the changes between bond mineral density(BMD) and body mass index(BMI) according to sex and age. Methods : We measured the bone mineral density(BMD) of lumber spine(L2-L4) and femoral neck in 10000 normal adult, using dual energy X-ray absorptiometry (DEXA; DPX-alpha). and also measured the body mass index(BMI) in 9810 normal adult. then we analysed the changes of BMD and BMI according to sex and age. Results : 1. As getting older, male's T-score of lumbar spine(L2-L4) was slowly decreased. On the other hand, female's T-score of lumbar spine was sharply dropped after 46 years old. 2. As getting older, male's T-score of femoral was slowly decreased. On the other hand, female's T-score of femoral was sharply dropped after 49 years old. 3. Irrespective of age, male's BMI keep up the extent within a definite period of numerical value. As getting older, female's BMI continued its upward trend. Conclusions : Much more attention should be needed for female patient suffering from osteoporosis and obesity than male.
