        여름작형 시설재배 파프리카의 주요 해충에 대한 생물적방제 기반 종합관리

        최만영,김정환,김황용,변영웅,이용휘 한국응용곤충학회 2009 한국응용곤충학회지 Vol.48 No.4

        Biological-control-based-integrated-pest-management of major pests occurring on sweet pepper in greenhouse during summer season was tried. As many as 2.1 Orius laevigatus per ㎡ were released in two times on June 6 and 19, and the population of thrips was kept under control and accordingly the damage was negligible throughout the season. To control aphids, a total of 0.8 Aphidius colemani per ㎡ were released in four times, 0.2 of them at a time, flonicamid on May 14 and July 18 and pymetrozine on June 14 and September 4 were sprayed on the spots of high aphid occurrence to reduce the release of the wasp, and the density of aphids was kept under control. Whitefly was controlled successfully by releasing a total of 343.4 Amblyseius swirski per ㎡ in nine times, 38.1 of them at a time, from May 9 until November 12 and dinotefuran was sprayed on November 12 when the density of whitefly increased up to 200 per trap. Tetranichus kanzawai was controlled by both Phytoseiulus persimilis which was released a total of 44.4 per ㎡ in five times 8.9 of them at a time from May 23 to September 10, and the A. swirski which was released for the control of whitefly.

        최만영,백채훈,서홍렬,이건휘,김재덕,Bernard D. Riotberg,Gerhard Gries 한국응용곤충학회 2006 한국응용곤충학회지 Vol.45 No.2

        Sex pheromone blends of large black chafer, Holotrichia parallela (Motschulasky), which consist of a major component L-isoleucine methyl ester (LIME) and a minor component (R)-(-)-linalool, showed different attractiveness depending on the mixing ratios of the two components in potato fields in South Korea. The best ratio for H. parallela attraction was 2.5:1 of LIME and (R)-(-)-linalool. The attraction ability of pheromone traps bated with 2.5:1 ratio did not drop up to 14m, but significantly decreased at 21m from H. parallela release point. Korean population of H. parallela showed almost same periodical activity to sex pheromone with that reported in Japan, which showing a circabidian periodicity of 48h cycle.

        명충알벌(Trichogramma. chilonis)의 사육 기주에 따른 왕담배나방과 담배나방에 대한 발육반응 및 기생률

        최만영,김정환,변영웅,김황용,김용헌 한국응용곤충학회 2010 한국응용곤충학회지 Vol.49 No.4

        The parasitism, development time, hatchability, and progeny production of Trichogramma chilonis(TC) females developed in eggs of Helicoverpa assulta (HAs), Cadra cautella (CC), and Helicoverpa armigera (HAr), repectively, were compared with those developed in reciprocal eggs at constant temperatures of 25±2℃ and relative humidity of 50~70% under 16L-8D. Developmental performances of TC reared in each of the three hosts on the following hosts(host tested) appeared differently, and were affected most by the size of the proceeding hosts and test host. Among the parameters parasitism and progeny production were affected more than others. Parasitism was significantly different between the treatments, lowest in CC-HAr(10.1±2.05%) and highest in HAr-HAs(47.0±2.09%), and the hatchability showed similar pattern. Development time as well was shortest in the CC-HAr where previous host is smallest and test host is biggest. The highest number of progeny production of TC was observed in HAr-HAs(93.9±6.87 wasps), and the lowest was CC-HAs(18.4±6.36 wasps).

        최만영,이종진,이건휘 한국응용곤충학회 1999 한국응용곤충학회지 Vol.38 No.1

        진딧물류의 천적인 칠성풀잠자리붙이(Chrysopa pallens Ramber)를 계란의 난황, 효모가 수분해물, 맥주효모 또는 Vanderzant의 비타민 혼합물, 설탕과 벌꿀 또는 설탕, 카세인가수분해물, 콜레스테롤로 구성된 인공사료를 이용하여 사육하였다. 인공사료의 조성에 따라 1령유충부터 사육한 결과 20~70%가 정상적인 성충으로 자랐으며, 사육성적이 가장 뛰어났던 인공사료를 성충에 먹였을 때 230개의 수정란을 36일간에 걸쳐 산란하였다. 복숭아진딧물의 비지질성분이 지질성분보다 칠성풀잠자리붙이의 발육에 영양원면에서 더 중요한 것으로 나타났다. An aphid predator, Chrysopa pallens Ramber, was reared on the artificial diets containing chicken egg yolk, yeast hydrolysate, brewer's yeast or Vanderzant's vitamin mixture, sucrose andlor bee honey, casein hydrolysate, and cholesterol. On these diets, 20.0 to 70.0% of the 1st instar larvae developed to apparently normal adults depending on diets used. The adults fed on one of these diets which was the most effective laid 230 fertile eggs for her 36 days of adult life span. The nonlipid part of the aphid, Myzus persicae Sulzer was thought to be nutritionally more important than the lipid part for the development of the green lacewing.

        진딧물류를 포식하는 혹파리, Aphidoletes aphidimyza(Roundani)(Diptera: Cecidomyiidae)의 복숭아혹진딧물 포식과 발육

        최만영,이건휘,백채훈,김두호 한국응용곤충학회 2001 한국응용곤충학회지 Vol.40 No.1

        진딧물류 천적 혹파리(Aphidoletes aphidimyza (Rondani))의 온도별 발육 및 복숭아혹진딧물에 대한 포식특성을 실험실 및 온실 조건에서 조사하였다. 온도와 유충의 발육속도와의 상관 을 구하였으며 ((regression; development rate (y) : 0.013348x (temperature)-0.173022, F = 41.14, p<0.01)), 발육영점온도는 $13^{\circ}C$이었다. $\25pm$2$^{\circ}C$ 에서 유충 발육기간은 5.3일 이었고, 1세대기간은 29 일이었다. 복숭아혹진딧물 밀도에 따른 혹파리의 포식량은 arena(직경 9cm)당 복숭아혹진딧물 10마리일 때 4마리를 포식하여 포화상태를 나타냈다. 온실조건에서 진디혹파리의 진딧물 포식은 지체적밀도의존반응과 유사한 반응을 보였다. Development and predation of an aphidophagous gall midge, Aphidoletes aphydimyza (Rondani) , on the green peach aphid, Myzus persicae Sulzer, were studied under laboratory and greenhouse conditions. The developmental threshold temperature of the gall midge larvae was estimated to be $13^{\circ}C$. Larval and total developmental periods were 5.3 and 29 days at 25 $\pm$$2^{\circ}C$. The gall midge attacked more aphids as increasing density of peach aphids, and consumed 4 out of 10 peach aphids per day in a petri dish (9 cm in diameter) at maximum. In green house, the gall midge could control the density of the green peach aphids efficiently with a delayed density dependent-like pattern.

        인공사료의 지질 및 탄수화물함량에 따른 칠성풀잠자리붙이 체내 지질합성 활성

        최만영,이건휘,이희권,이종진 한국곤충학회 1998 Entomological Research Vol.28 No.3

        칠성풀잠자리붙이의 인공사료 섭취량 측정과 먹이중 탄수화물 및 지질 함량에 따른 체내 지질합성활성을 분석하기 위하여 방사성동위원소($^{14}$ C-sucrose)를 이용하였으며, 먹이 섭취후의 글리코겐, 지질, 단백질에 표식되는 동위원소의 선량을 측정하였다. 그 결과 3령 탈피 직후의 유충의 경우 먹이공급 후 2시간내에 3${\mu}\ell$을 섭취하였고, 그후 4시간이 더 경과할 때까지 섭취한 먹이의 양은 아주 소량에 불과하였다. 먹이공급 후 6시간 이후의 칠성풀잠자리붙이 충체내 RI(Radioisotope)활성의 80%가 당에서 검출되었고, 단백질과 지질에서 각각 10%정도가 검출된 반면에 글리코겐에서는 6%정도만 검출되었다. 인공사료중 탄수화물의 함량이 맡을수록 그리고 지질함량이 적을수록 체내지질에 표식되는 방사선량은 많았다. Radioisotope ($^{14}$ C-sucrose) was used to measure the amount of an ingested artificial diet by a green lacewing, Chrysopa pallens Ramber, and the effect of the dietary contents of carbohydrate and lipid on the synthetic activity of total lipid were measured using $^{l4}$C-sucrose included in diets. The radioisotope incoporated into glycogen, lipid, and protein were measured 6hr after diet ingestion. A newly ecdysed 3rd instar larvae ingested approximately 3${mu}ell$ of the artificial diet within 2hr after food supply, then ingested slight amount for further 4hr. The radioisotope was distributed ca. 6% in glycogen, 80% in carbohydrate, 10% each in protein and lipid fractions 6hr after food ingestion. The $^{14}$ C-labeled lipid content in the green-lacewing body were higher with higher carbohydrate contents and with lower lipid contents in test diet.t.

        마산-진해만에서 Prorocentrum 개체군의 발생양상과 분포

        최만영,곽승국,조경제 한국환경생물학회 2000 환경생물 : 환경생물학회지 Vol.18 No.4

        Genus Prorocentrum of dinoflagellate has been known as representative causative algae of red tide in Masan-Jinhae Bay. Prorocentrum populations-P. dentatum Stein, P. micans Ehrenberg, P. minimum(Pavillard) Schiller and P. triestinum Schiller- were monitored from January 1996 to August 1997. Prorocentrum populations usually have bloomed during the water stratification periods from June to August. Water temperature ranged from 24℃ to 28℃ and salinity from 24‰ to 34‰ during the Prorocentrum blooms. Bloom magnitude of Prorocentrum populations gradually increased from offshore to inshore area of coastal embayment and this populations tended to concentrate from surface to 2.5m depth. Prorocentrum algal blooms have become more frequent and intense than those of 1980s and early 1990s. P. minimum was the most persistent species in terms of bloom frequency and cellular abundance.
