Ricania sublimata are insects invaded in South Korea from China 2011. It has been happening continuously since invaded and It is established and continues to increase and occur in various crops such as persimmons, peaches, and apples. The nymphs and adults of R. sublimata causes damage by sucking the stems and leaves of trees. Yellow, blue, and white sticky traps (25x15cm) were installed in the 1000m2 Omija(Schizandra Chinesis Baillon) orchard september 2020 and the trap captures by color was investigated. In addition, yellow sticky traps were installed at heights of 1m, 1.7m, and 2m, and the trap captures according to the height was investigated. As a result of attraction according to the color of the sticky trap, yellow trap was the most attractive, blue and white traps had little attraction. And result of capture according to the yellow sticky trap height the most were caught at 1.7m height, followed by 1m and 2m in that order. Therefore, it is considered reasonable to investigate the density and monitoring of R. sublimata using yellow sticky trap.

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.

시판되고 있는 51종(단제 21종과 합제 30종)의 살충제를 이용한 꽃노랑총채벌레와 대만총채벌레 성충에 대한 약제 감수성을 검토한 결과 90% 이상의 살충률을 보인 약제 15종을 선발하였으며, 시판되고 있는 합제에서 많은 유효성분들이 오남용되고 있다고 보여진다. 2종의 총채벌레에 대한 살충제 감수성을 비교한 결과 모든 약제에 대하여 대만총채벌레가 꽃노랑총채벌레에 비해 높은 감수성을 보이기 때문에 꽃노랑총채벌 레에 효과 있는 약제로 동시방제가 가능할 것으로 판단된다. 꽃노랑총채벌레를 대상으로 선발된 15종의 약제를 이용하여 약효발현속도(LT50과 LT95), 침투이행성, 잔효성을 비교하였다. 약효 발현속도를 LT95 (hour)값으로 비교했을 때, chlorpyrifos WP, chlorpyrifos + diflubenzuron WP가 2시간 이내로 가장 빨랐고, spinetoram WG은 62.3시간으로 가장 느렸다. Chlorfenapyr SC에서 뿌리와 엽면을 통한 침투이행 효과가 나타났고, spinetoram WG에서 엽면을 통한 침투이행 효과만이 나타났다. 약제 잔효성 실험에서 chlorfenapyr SC는 14일, benfuracarb WG 와 chlorpyrifos WP는 3일까지 효과가 지속되었다. 꽃노랑총채벌레 야외집단(화훼재배지와 과채류재배지)간의 감수성 비교에서는 화훼재배지에서 채집된 집단이 더 낮은 약제 감수성을 보였다.

Acrolepiopsis nagaimo (Yasuda, 2000) belonging to the family Acrolepiidae (Lepidoptera) is newly discovered in Korea. The species was first collected wild at Wol-ak-san [Mt.] a few years ago and they were recently found to infest Chinese yam, Dioscoreabatatas at a Chinese yam experimental field of the Institute for Bioresources Research located at Andong. Diagnostic characteristics of the adult are described and photographs of adult and male and female genitalia are provided.
