모기류는 흡혈을 통해 원충, 바이러스, 사상충 등 다양한 병원체를 보유하며 말라리아, 일본뇌염, 웨스트나일 열, 뎅기열 등을 사람에게 매개하는 위해성이 있는 위생해충이다. 이번 연구에서는 해외유입 모기류 감시를 위해 경남 고성지역에 설치한 스마트 고공포집기를 이용하여 2022년부터 2023년까지 모기류들을 모니터링하였다. 조사기간 동안, 총 3속 5종 43개체가 채집되었으며, 이중 삼일열 말라리아를 매개하는 Anopheles belenrae를 경남 지역에서 처음으로 발생함을 확인하였다. 본 연구는 해외유입 모기류에 대한 감시망 구축의 최초 시도로서, 고공 포집기를 활용하여 모기류 감시가 가능함을 확인하였다.

Currently, flies are used to pollinate Welsh onion for seed production. However, the use of flies for pollination has caused problems in Welsh onion seed production due to sanitation issues, smell, and the difficulty of feeding the flies. Therefore, we investigated the effects of pollination with bumblebees (Bombus terrestris), flies (e.g., houseflies, flesh flies, blue bottle flies), mason bees (Osmia cornifrons), honeybees (Apis mellifera) and blowflies (Lucilia illustris) in a small net screen house (2.2m×1.7m×2.5m) for onion seed production. Although the number of flies was about three times than that of other insect pollinators, fies and bumblebees showed equivalent pollination ratios, but the remaining three insect species showed lower values. For the percentage of seed set per umbel, the number of seeds per flower and umbel, bumblebees and flies showed similar results. These results showed that pollination by bumblebees can be used as an alternative approach in breeding Welsh onion. An analysis of the most appropriate colony of bumblebees for use as pollinators for breeding Welsh onion in a small net screen house showed that colony of fifty to eighty bees was the most efficient level. The visiting time on the flower and spending time from a flower to another flower of B. terrestris worker on small net screen house was 2.2 seconds and 1.8 seconds, respectively.

In recent years, not only the cultivation area of Jujube in Korea but also the number of pest species has increased. The farmers farming environmentally friendly are in great difficulty because there are no effective control devices. This study was conducted to investigate the control effect of the insect screen net on three pest species (Apolygus spinolae, Dasineura sp. and Carposina sasakii) in Jujube orchard when the pests were blocked by insect screen net. For the first and second surveys, the damage rates by A. spinolae were 9.06, 13.95% in 50 mesh, 4.75, 10.17% in 25 mesh, 5.68, 11.84% in 18mesh mesh of insect screen net and 21.6, 36.34% in untreated insect screen net, respectively. The damage rates by Dasineura sp. were 0.54, 0.13% in 50 mesh, 0.93, 2.84% in 25 mesh, 1.05, 13.45% in 18 mesh mesh of insect screen net and 11.1, 26.65% in untreated insect screen net. Carposina sasakii were completely blocked in all the treatments. Damages on Jujube were not observed by insect screen net. Therefore, insect screen net is effective on insect pest control for Jujube.

구기자(枸杞子) 재배시(栽培時) 생육환경(生育環境)을 개선함으로써 건전한 생육(生育)을 도모하여 수양성(收量性)을 증대하고 농약방제(農藥防除)에 소요되는 노력을 절감하면서 안전 농산물(農産物)을 생산키 위하여 1992년(年) 비가림 망실재배시험(網室栽培試驗)을 수행하였던 바 그 결과를 요약하면 다음과 같다. 1. 평균(平均) 기온(氣溫)은 비가림 망실재배시(網室栽培時) 노지자연재배에 비하여 1~1.9℃가 높았고, 병충해 방제횟수는 비가림 망실재배가 2회, 노지재배가 7회이었다. 2. 지상부(地上部) 생육(生育)은 망실재배(網室栽培)가 노지재배에 비하여 양호하였다. 3. 비가림망실재배가 노지재배에 비하여 탄저병의 이병과율과 혹응애 발생을 현저히 감소시켰다. 4. 수량은 비가림 망실재배시 환기처리 204kg, 미환기처리 218kg으로 노지재배에 비하여 92~106% 증수하였고, 이는 병충해 감소에 의한 주당과수의 확보에 기인하였다.
