수단과 우리나라에서 수집된 12 가지 식물체 추출물(메탄올 추출 9종, 헥산추출 3종)을 이용하여 실내에서 뿌리혹선충(Meloidogyne incognita)의 부화에 미치는 영향을 조사하였다. 10,000 ppm, 1,000 ppm, 100 ppm 농도의 식물체 추출물에 뿌리혹선충 알을 넣고, 3일과 7일, 21일 후 부화 된 알의 수를 조사하였다 모든 식물체 추출물 처리에서 무처리에 비해 뿌리혹선충 난의 부화억제 활성이 있었다. 농도가 높을수록 부화억제 활성이 높았는데, 10,000 ppm 농도에서는 Quisqalis indica 처리를 제외하고 소수의 개체만이 부화하였다 그리고 Q. indica 처리에서만 7일과 21일째 84.4%와 54.4%가 부화하였고, 대부분의 처리에서는 7일째 이후에 부화되는 알이 없었다. 1,000 ppm농도에서는 10,000 ppm 농도에 비해 부화율이 높았는데, Cucumis mello var agrestis 처리에서 부화율이 가장 낮아 3, 7, 21일 후에 각각 2%와 8%, 3% 만이 부화하였다. 100 ppm 처리에서는 Desmodium caudatum 처리에서 처리 3일과 7일째 부화되는 알의 수가 가장 적었다.
The inhibitory effect of herbal extracts using methanol and hexane collected from Sudan and Korea was evaluated on egg hatching of Meloidogyne incognita. The concentration of herbal extracts were 10,000, 1,000 and 100 ppm, respectively. They were treated to Meloidogyne incognita eggs after 3, 7, and 21 days of hatching. All herbal extracts inhibited egg hatching significantly compared to the control. The degree of inhibition was directly related to the concentration of the extracts. At 10,000 ppm, very fewer individuals were hatched at all the periods of exposure with the exception of the extract of fruits of Quisqalis indica which gave 84.4 and 54.5% at 7 and 21 days, respectively. Egg hatching was completely ceased, especially after 7 days for most of the extracts. While at 1,000 ppm relatively high numbers of eggs were hatched compared to the higher concentration, as well the extracts Q. indica reported many number of hatched eggs compared to others, especially at 21 days. On the other hand, the extract from pods of Cucumis mello var agrestis gave the least hatching number of eggs at all periods of exposure which gave 2, 8, and 3% at 3, 7, and 21 days, respectively in comparison to the control. Whereas at 100 ppm, inhibition increased with exposure time. However, the extract leaf of Desmodium caudatum represented the fewer hatching eggs at 3 and 7 days.
