벗초파리기생벌인 A. japonica의 벗초파리 유충의 발육단계에 따른 기생특성과 기생당한 유충과 번데기에서 형태적인 차이를 조사하였다. 또한 A. japonica의 우화기간이 벗초파리 우화일수 보다 더 소요되는 것을 확인하였다. A. japonica는 벗초파리 유충에 효과적인 기생 및 살충 효과를 나타내었으며 벗초파리 방제를 위한 천적으로 활용이 가능할 것으로 보인다.

Mealworm(Tenebrio molitor) was added to the feed to improve the health of dogs. As the amount of mealworm powder added to dog feed increased from 2.5 to 7.5%, the contents of crude protein, crude fat, crude fiber and crude ash increased. In the old dogs, creatinine and BUN related to nephropathy, triglyceride related to hypertension, calcium related to osteoporosis, globulin related to immunity, and ALT related to hepatic function were in the normal range. Particularly, ALT showed a tendency to increase overall, but the numerical increase tended to decrease as the amount of mealworm powder added. In the young dogs, all investigative items such as BUN and creatine were in the normal range and ALT tended to decrease at 2.5～5.0% treatment of mealworm. As a result, it was shown that adding 2.5～5.0% of mealworm powder to feed effectively improved the hepatic function of old and young dogs.

This study was carried out to confirm the predatory and developmental features of N. stenoferus. We determine the host range of N. stenoferus. As a result, it was confirmed that Aphis gssypii, Myzus persicae, Planococcus citri, and Frankliniella occidentalis. N. stenoferus is thought to be able to feed on other micro pests. The test for a developmental period of N. stenoferus at 25℃ showed that the egg period was about 10 days. The nymphal period was about 18 days. Each nymphal period from 1st instar to 3rd instar nymphs was about 3 days. And the nymphal period of 4th and 5th were about 3.5 and 6 days, respectively. The female adult laid eggs in stem tissue or on leaves, and sometimes on the soaked cotton for water supply.

This study was carried out to confirm the parasitic and developmental features of A. japonica and D. suzkii was used as a parasitic natural enemy. A. japonica attacked the D. suzukii larvae and the emergence of adults were observed from D. suzukii pupae. Black spots were observed in parasitized D. suzukii larvae. Mortality of parasitized larvae, rate of parasitic and developmental feature were investigated according to developmental stages of host, D. suzukii. Mortality and rate of parasitic of D. suzukii larvae were the highest when second instar larvae were attacked. Developmental period of parasitized D. suzukii larvae showed differences to developmental stages, but there was no significant difference in developmental stage of pupal period.
