Schizandra chinensis is one of the local special crops grown in Mungyeong, more than 70% of Gyeongbuk area. Scirtothrips dorsalis(Hood) are the most damaging pests among the insects that occur in the Schizandra chinensis, mainly affecting fruit quality, yield and quality. Therefore, it is necessary to study how to reduce the damages by establishing efficient forecasting method and pesticide control system for the Scirtothrips dorsalis(Hood) occurring in Schizandra chinensis. Scirtothrips dorsalis(Hood) was surveyed with yellow sticky traps from April to September in the Mungyeong area. Scirtothrips dorsalis(Hood) has the highest density in July, beginning in early May, and then again in September. Therefore, the suitable time to control the Scirtothrips dorsalis(Hood) is in late May, early July, and mid August. Three species of pesticides(Spinetoram WG, Emamectin benzoate EC, Chlorfenapyr EC) registered in Scirtothrips dorsalis(Hood) were treated three times at the suitable time, as a result of the treatment, a high effect of 92% more.

Schizandra chinensis(Turcz.) Bail is one of the local special crops grown in Mungyeong, more than 70% of Gyeongbuk province in South Korea, and various pests are emerging due to recent climate change and intensive cultivation. Scirtothrips dorsalis(Hood) are the most damaging pests among the insects that occur in the Schizandra chinensis(Turcz.), mainly affecting fruit quality, yield and quality. The survey was conducted from February 2017 to September 2018 in three locations in Mungyeong area. Blue and yellow traps were used to investigate the occurrence patterns and the degree of damage. As a result of the survey, Scirtothrips dorsalis(Hood) occurred first in flowering period in May, and then occurred in fruits. The occurrence density was highest in July. It was confirmed that the attractiveness of each trap color was blue in the early stage of growth and yellow in the late stage but there was no significant difference in the whole.

The study was carried out to know the occurrence of the chilli trips of two varieties from three grape farm in Kyeongsangbukdo province, Korea. During the grape fruiting season, this work surveyed at intervals of about fifteen days from Jun to September, 2015 by using the yellow sticky trap. The peak occurrence time of chilli thrip at Hwaseo-myeon was in September and was August at Modong-myeon. The Gyeongsan site was almost more three times high occurrence density than that of Hwaseo-myeon and Modong-myeon of Sangju area. According to the variety and locality, occurrence time and density were different hightly.

볼록총채벌레의 겨울철 실내 실험과 정확한 데이터 수집을 위해 실내 사육법 확립을 시도하였다. 채집의 경우 제주도에서 많은 피해가 나타나는 키위과원에서 실시하였으며 여름전정 후 버려진 잎에 볼록총채벌레의 유무를 확인 후 이를 이용하였다. 볼록총채벌레가 존재하는 키위잎을 사육실내의 본엽이 10엽 이상인 고추묘목에 놓아 자연스럽게 이동하도록 유도하였다. 사육실 환경은 LED형광등을 설치하였으며 조사시간의 경우 16L:8D로 설정하였다. 온도의 경우 30 ± 2℃를 유지하였으며 습도의 경우 가열식 가습기를 설치하여 상대습도 60~80%를 유지하였다. 먹이의 경우 1차 기주식물로 알려진 것 중 지속적인 먹이공급이 가능하고 관리가 용이한 고추와 애플망고를 이용하였다. 고추씨로 직접 묘목을 만들어 지속적인 먹이 공급을 실시하였다. 하지만 본옆이 6개 이하인 고추를 먹이로 공급하였을 경우 16일만에 모든 잎에 탈락하여 먹이원으로 적합하지 않았다. 애플망고의 경우 고추에 비해 잎이 탈락하는 비율은 낮으나 잎이 경화되기 까지 약 50일이 소요되고 그 이후로는 먹이원으로서의 기능은 현저히 떨어지는 것을 확인하였다. 볼록총채벌레의 경우 많은 기주식물을 가지고 있어 먹이원의 질이 떨어지면 다른 기주식물을 찾아 이동하는 습성이 있다고 알려져 있다. 고추와 애플망고를 함께 먹이원으로 공급하면 증식률을 높게 유지 시킬 수 있었다.

Yellow tea thrip (Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is anthophilous pests of many crops worldwide including five flavor berry. And the mealy bug (Pseudaulacaspis cockerelli (Cooley) (Hemiptera: Diaspididae)) is one of the hardest pests to control. Its body is covered with white waxy threads, which often make a chemical pest control useless. Five flavor berry (Schisandra chinensis Baill) is used in traditional Chinese medicine. So, the development of biological control against the major pest on five flavor berry is of great interest. In this work, a treatment of Chrysoperla nipponensis (Okamoto) was applied to five flavor berry fields infested by P. cockerelli and a treatment of Amblyseius swirskii Athias-Henriot was applied to two types of five flavor berry fields infested by S. dorsalis. Even though our tests found significant differences between the two culturing method(sod culture, nonwoven type mulching), the treatment of biological control agents decreased or a little increased the fruit damage, which was comparable to the chemical insecticide treatment. In the sod culture experiment, thrip population was significantly low and increased at a lower rate than in the nonwoven type mulching. It may be suggested from these results that A. swirskii and C. nipponensis as IPM program and sod culture could be incorporated into the integrated pest management system on five flavor berry.

노지 재배 오미자(Schisandra chinensis Baill)포장에서 재배양식(초생재배, 부 직포 멀칭 재배, 혼합 재배)의 차이에 따른 친환경관리구와 관행관리구의 볼록총채 벌레(Scirtothrips dorsalis Hood)의 계절별 발생 정도의 차이를 조사하였다. 초생 재배지의 경우, 친환경 관리 구와 관행 관리 구 모두에서 6월 상순과 7월 상순에 두 번의 발생피크를 보였다. 볼록총채벌레가 월동 후 오미자나무 주위의 식물체에서 서식 하다가, 5월초부터 오미자에 발생하는 것으로 보여진다. 6월초의 경우에는 기 존 관행 관리 구에 비해 친환경 관리 구에서의 볼록총채벌레 발생밀도가 50% 수준 인 30마리 정도로 전체적으로 낮은 것을 확인할 수 있었다. 부직포 멀칭 재배지의 경우, 친환경 관리 구와 관행 관리 구 모두에서 5월부터 볼록총채벌레가 발생하여 증가하기 시작하여 7월 중순부터 급격히 증가하였고, 두 관리구 사이에는 뚜렷한 밀도 차이가 보이지 않았다. 혼합재배지의 경우, 친환경관리구에서의 해충발생밀 도는 관행관리구의 37.5~50% 수준이었다. 이상의 결과를 조합해보면 주변 잡초에 의한 볼록총채벌레의 밀도 분산효과와 천적의 서식처 역할로 사실상 초생재배는 50% 이상의 병해충 방제효과를 갖는다고 볼 수 있다.

 ,  , Silver-grey or dark brown scaring, or dark brown discolored damages caused by the yellow tea thrip, Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) have occurred on citrus fruits cultivated in the open field in east-south area orchards of Jeju Island since 2007. The weekly population of yellow tea thrips adults caught with a yellow sticky trap increased gradually from early May and peaked in late August, 2009. In 2010 and 2011, the most population was in early October. The yellow tea thrips of some species usually dominated from July in open citrus fields, and seven generations, at least, had occurred from May to late October 2009 by a yellow sticky trap survey. In 2009, S. dorsalis larva were observed from July and with peaks from late August to mid September and early October on citrus fruits. The damage symptoms appeared in the mid September. In 2011, the population peaks were in early July and late September, and the symptoms increased continually from mid July to late October. The symptoms were silver-scars or initial dark discolorations and then gradually changed to dark-brown discolorations or dark-brown scars. The percent of damaged fruits were 0.9%, 0.4%, 0.8% and 2.7% in 2008, 2009, 2010 and 2011, respectively, by survey in 64 typical orchards in Jeju Island. We are the first to report symptoms of the yellow tea thrip (Scirtothrips dotsalis) on citrus fruits.
