북미 원산인 아까시나무는 우리나라에 1900년대 초에 도입되어 원료림과 황폐지 복구용으로 조림되었으나 점차 산림이 녹화되고 이제는 산림의 오히려 망치는 나무로 오인되어 사람들의 미움을 받고 있는 실정이나, 우리에게 아까시아 꿀과 5월에 아까시아 향을 뿜어내며 꽃잎이 휘날리는 아름다움 전경은 많은 사람에게 추억으로 남아 있다. 또한 목재는 강도가 좋아 차량재, 목공예용으로 사용되어 버릴 것 하나 없는 우리에게 즐거움만 주는 나무이다. 하지만 이러한 나무에 해충이 피해를 주니 이들의 종류 및 생태 그리고 방제에 대하여 소개하고자 한다.

This report describes the damage caused by gypsy moths (Lymantria dispar) and stick bugs (Ramulus mikado) to forests and host plants in 2020. Severe tree-crown defoliation was found in central parts of Korea, especially Gangwon (1,638 ha), Gyeonggi (1,134 ha), Chungbuk (726 ha) and Seoul (476 ha). Stick bug outbreaks occurred in hilly areas, such as Mt. Bongsan, located between Seoul and Goyang.

농약은 농산물 생산에 있어서 병해충 및 잡초를 방제함으로써 생산성을 높이는데 필수적인 농업자재로 인식하고 있다. 그런데 모든 화학물질이 그러하듯이 농약도 두 가지 양면성을 지니고 있다. 즉, 약효와 독성이다. 일반적으로 농약은 뿌려진 농약의 $0.1\%$이하만이 목표물이라고 할 수 있는 해충 및 잡초, 이병작물에 떨어지고 그 외는 비표적 생물 및 환경매체에 떨어짐으로써 생태계에 영향을 준다고 한다. 약효는 농약으로서 지녀야 하는 당연한 기능이지만 독성은 가능한 줄여야 할 기능이기 때문에 농약회사에서는 약효는 높으면서 사람과 생태계에는 좀 더 안전한 농약을 개발하기 위해 애쓰고 있다. 우리나라는 전세계적으로 볼 때 농약을 비교적 많이 사용하는 나라로 알려져 있으나 경제규모 및 사용량에 비해서 생태계에 대한 농약관리는 앞서가지 못하고 있는 것이 현실이다. 따라서 농약의 생태위해성 평가에 대한 기본적인 이해를 돕기 위해 이번호부터 연재를 통해 생태위해성에 대한 기본개념을 소개함과 동시에 국내외 농약등록제도에서의 생태위해성 의사결정 과정을 비교하고 마지막으로는 국내 농약관리제도에 있어서 생태독성분야의 의사결정에 대하여 개선방안을 제안하고자 한다.

Natural Enemy in First (NEF) method is an ecological engineering application technology for natural enemies and was applied to strawberry in a smart farm-type greenhouse to evaluate its effect on the density of thrips and aphids. The control group was treated with pesticide and compared with the NEF treatment group, in which Orius minutus and Portulaca sp. were used as a natural enemy and habitats for thrips and aphids. The density of pests in the NEF group was effectively managed and similar to that in the control group.

전국 어디서나 쉽게 볼 수 있는 참나무류는 가을이면 우리에게 정성스러운 열매를 도토리라는 정겨운 이름으로 우리에게 돌려준다. 그리고 우리 조상들의 예로부터 도토리를 슬기롭게 이용하여 와KT고, 야생동물의 긴요한 식량으로 사용되어, 자연을 풍요롭고 아름답게 만드는 슬기로운 산물이다. 자연을 표방하는 기획물 사진에는 다람쥐가 도토리를 먹고 있는 모습이 대표되는 한 장면이기도 하다. 우리나라 전국어디서나 신갈나무, 갈참나무, 떡갈나무, 굴참나무, 상수리나무, 졸참나무 등 많은 참나무류가 분포하여 가을이면 단풍의 극치를 이루기도 한다. 이들이 만들어내는 종자에 해충이 탐을 내어 우리의 정서를 빼앗고 있다 대표적인 것이 요즘 등산로나 산책로를 따라 가면 길 위에 많이 떨어져 있는 참나무류 가지들의 피해는 도토리거우벌레의 피해이다. 마치 톱으로 참나무가지를 잘라 떨어뜨리는 모습은 자연의 신비가 오묘하다는 것을 말해 주기도 한다. 구과에 알을 낳고는 가지를 주둥이로 잘라서 떨어뜨려 어린자식이 도토리를 먹고는 쉽게 땅속에서 들어갈 수 있게 하는 것이다. 참나무류 도토리를 직접 가해하는 몇몇 해충에 대한 생태 및 방제법을 간략하게 소개하고자 한다.

Pristiphora (Pristiphora) apricoti Zinovjev, 1993, pest of Prunus armeniaca var. ansu Max, belonging to Nematinae of Tenthredinidae is newly recognized in South Korea. The host plant is recorded for the first time from South Korea. Diagnosis, rearing notes, and photographs of the diagnostic characters and oviposition are provided.

In this study, we report three insect pest species of non-astringent persimmon, Pleuroptya chlorophanta, Acria ceramitis, and Choristoneura longicellana, for the first time from Korea. Larvae of these species were collected from an organic farming persimmon orchard in Changwon city, Gyeongnam province, and reared in the laboratory to be identified in 2012. Some information, such as collection records, hosts, simple morphological characteristics, and ecology were introduced for each species.

We report three lepidopteran insect pests of non-astringent persimmon leaf for the first time from Korea; Hypocala deflorata (Noctuidae), Teliphasa elegans (Pyralidae), and Cuphodes diospyrosella (Gracillariidae). Larvae of these species were collected from an organic farming or abandoned persimmon orchard in Changwon and Jinju cities, Gyeongnam province, and reared for the identification in the laboratory. Some information, such as collection records, hosts, simple morphological characteristics, and ecology were introduced for each species.

Insect pests have been one of the main constraints affecting turf sod cultivation areas, playgrounds, parks, golf courses, airports and other related recreational grounds. However, turfgrass research has been very limited and confined within a limited period of time compared to other branches of crop science in Korea. This review was surveyed from all papers in KCI (Korea Citation Index), SCI (Scientific Citation Index) and SCIE (SCI Expended) journals related to turfgrass research in Korea. Fifty two papers concerning turfgrass insect pest in Korea have hitherto been published in 8 different scientific journals since 1990. Thirty three papers (63.5% of total) were published in Weed and Turfgrass Science. The main topics of focus were divided into two parts; ecological study and control of insect pests. Before the 1990 decade, there were no scientific papers published in relation to turfgrass insect pest science. However, during the 1990, 2000 and 2010 decades, 9, 10 and 14 papers were published respectively in Weed and Turfgrass Science. From 1997, about 2 papers were published per year in the scientific journals. Thirty three insect pest species belonging to 13 families in 6 orders, one Eriophyidae mite, Aceria zoysia and one Armadillidae sowbug, Armadillidium vulgare, have hitherto been listed as turfgrass arthropod pests in Korea. Fifty percent of turfgrass insect pest papers published were focused on whitegrub, Adoretus tenuimaculatus, Popillia quadrigutta and earthworm research in Korea.

This study was conducted to analyze arthropod community patterns in small rice fields associated with different planting methods (water seeding, drill seeding, and hansplanting) in Suwon and Icheon in 1994. Total 15 orders and 45 families of arthropods were collected. The arthropod community was analyzed using guild categories. The arthropods were found in the order of 'natural enemy>pest(phytophage)>non-pest' in their densities in all sites. The pest (phytophage) species were mainly Homoptera and dominated by Delphacidae (Nilaparvata lugens Stsl, Sogatella fircifera Horvath and Laodelphax striatellus Fallen) and Cicadelidae (Nephotettir cincticeps Uhler). They constituted >80% of pest abundance. Differences in pest abundance were not found among rice fields associated with different planting methods. Spiders were the most dominant group in the natural enemy and constituted >90% of natural enemy abundance. Hunting spiders constituted >SO% of spider abundance and were dominated by Pirata subpiraticus Bos. et Str. (Lycosidae). Pacliygnatha clerki Sundevall (Tetragnathidae) was a dominant species in webbing spiders. No differences were found in species richness and diversity in spider community among rice fields associated with different planting methods. The nonpest species were mainly Diptera and occurred abundantly in early growing season and decreased drastically as rice development proceeded. The non-pest abundance was higher in direct seeding sites than in transplanting site, and especially abundant in a drill seeding site.
