Abstract

Tomato russet mite, Aculops lycopersici Massee (Acari. Eriophyidae) was recorded in Korea and their SEM observations, distribution, host range, development on different temperature, and chemical control method were studied. Tomato russet mite is a microscopic animal (134.9 $\mu\textrm{m}$) with 2 pairs of legs which had 4 rays of feathered craw. Infected leaf turn reddish brown, stem loss hair, become shiny or surface cross-cracked, and shoot wilted or shrunk. Surface of fruit around fruit stalk appeared rusted or cross-cracked. It was found in glass greenhouse at Buyeo and Yuseong in Chungnam Province, Pyeongchang in Gangwon Province, and Chilgok and Guryongpo in Gyeongbuk Province. Convolvulus, black nightshade, chinese lanternplant, eggp1ant, morning glory, petunia, potato, pepper, tobacco and tomato were confirmed as a host plant in inoculation test. It could develop at temperature around $15-30^{\circ}C$, it took 6-11 days from eggs to adult, higher temperature shorten its life cycle. Female lived longer than male and it lived as long as 12 days at 25-28"C. Among acaricides tested, fenazaquin and cypermethrin were most effective.tive.

토마토녹응애(개칭)에 대해 주사전자현미경 관찰, 국내 분포, 기주식물, 온도에 따른 발육상, 약제 방제법에 관하여 연구하였다. 토마토녹응애는 2쌍의 다리를 가진 길이 $134.9\mu\textrm{m}$의 미소동물로 feathered claw는 4줄이었다. 피해증상으로, 피해엽은 적갈색으로 변하고 줄기에는 털이 없어지고 광택이 나거나 표면이 그물형으로 갈라지며, 새순은 시들거나 위축된다. 과일은 과경 부근에 그을음이나 녹이 긴 것 같이 되고, 그물형으로 갈라진다. 충남의 부여와 유성, 강원도 평창, 경북의 칠곡, 구룡포의 유리온실에서 발견되었으며, 한국에서 기주로는 메꽃, 까마중, 가지, 꽈리, 나팔꽃, 페투니아, 감자, 고추, 담배, 토마토 등이 확인되었다. 이 응애는 $15-30^{\circ}C$에서 발육이 가능하였고, 한 세대는 6-11일로 높은 온도일수록 발육기간이 짧아지는 경향이었으며, 암컷이 수컷보다 수명이 길었는데, 25-28$^{\circ}C$에서 12일로 가장 수명이 길었다. 살비제 중에서 fenazaquin과 cypermethrin의 효과가 가장 좋았다.
