무가온 시설토마토 재배지내에서 토마토녹응애 발생양상은 4월 중하순경 최초로 발생하기 시작하여 6월 중하순경 최대 발생을 나타냈다. 하지만 야간기온이 낮을 경우 번식력이 증가하게 되고 주간기온이 높을 경우에는 분산이 활발해져 고온기인 7월에도 지속적으로 증가하는 것으 로 조사되었다. 유기농업자재 11종에 대한 토마토녹응애의 살충독성 실내검정 결과, EOIMa (Matrin 0.6%), EOICo (Clove oil 10%)가 500 배에서 각각 92.1%와 95.1%로 90% 이상의 살충효과를 보였다. 특히 EOIMa 1,000배에서는 90.4%로 90%, EOIMa 2,000배에서는 88.2%의 높은 살충효과를 보였다. 포장검정에서도 EOIMa 1,000배와 EOICo 500배는 각각 91.5%와 93.9%의 살충효과를 보여 두 약제 모두 농약을 대 체하기에 충분하였고 EOIMa의 경우 2,000배에서도 살충효과가 90%에 가까웠기 때문에 예방적 활용도 가능할 것으로 판단되었다.

The first occurrence of the tomato russet mite, Aculops lycopersici Massee was in mid-late April, and the maximum occurrence was in mid-late June in 2013 and 2014. However, in 2015, the density of tomato russet mites increased in July. This pattern is thought to be attributed to temperature fluctuations, in which, low temperatures at night promoted their reproduction and long periods of high temperatures during the day promoted their dispersion. Comparison of the use of 11 Eco-friendly organic insecticides (EOIs) showed that, the mortality rates after application of 0.6% matrin(EOIMa) and 10% clove oil (EOICo) were 92.1% and 95.1%, respectively, when administered at 500-fold diluted concentrations. At 1,000-fold and 2,000-fold diluted concentrations, the mortality rates of EOIMa were 90.4% and 88.2%, respectively. In a field test, the mortality rates of EOIMa at the 1,000-fold diluted concentration and of EOICo at the 500-fold diluted concentration were 91.5% and 93.9%, respectively. In conclusion, theses two EOIs are sufficient to replace pesticides, and EOIMa seems to be particularly useful as a prophylactic given that it induced a mortality rate of 88.2% at a 2,000-fold diluted concentration.
