초록
벼멸구에 대한 통일품종 (IR-667 계통)의 내충성징도와 그들이 벼멸구에 미치는 생물학적 영향을 비교검토 코자 본 실험을 실시하여 다음과 같은 결과를 얻었다. 1. 통일품종은 다른 한국장려품종에 비해 약간 내성을 보이나 감수성이었으며 식이 및 산란선호성이 높았다. 2. 저함성품종인 Mudgo, MGL-2, ASD-7 등은 식이 선호성이 매우 낮았으나 산란선호성은 오히려 높았다. 3. 감수성품종인 수원 214와 저항성품종인 ASD-7간에 벼멸구의 산란성은 각 품종 단독구에서는 수원 214에 많은 산란량을 보이나 두 품종 공동산란구에서는 ASD-7에 압도적으로 많은 산란을 보였다. 4. 감수성품종(T(N)-1, 수원 213-1, 수원 214)과 저항성품종(ASD-7, Mudgo)에서 사육한 벼멸구의 난기, 부화율은 차이가 없었으나 1) 약충기는 저항성품종에서 길고 감수성품종에서 짧았으며, 2) ② 부화율은 수원 213-1
This study has been carried out to investigate the varietal resistance of Tong-il rice variety (IR-667) at the seedling stage to the brown planthopper. Nilaparvata lugens STAL, and further to know the biological effects of the varieties to the insects. The results obtained were as followings; 1. Tong-il variety tested in this experiment was susceptible to the brown planthopper but it seemed to be a little more tolerable than the Japonica varieties which had been recommended in Korea. 2. Tong-il variety (Suwon 213, Suwon 213-1, Suwon 214, and Suwon 215) was highly prefered by brown planthopper for feeding to the Korean recommended varieties Paltal, Jinheung, Akibare, and Shin #2. 3, The resistant varieties Mudgo, Kayama MGL-2, and Karsamba ASD-7 which showed low feeding preference exhibited higher ovipositional preference than the susceptible varieties. Relatively greater number of eggs was recorded on the Tong-il variety (Suwon 213, Suwon 213-1, and Suwon 215) in comparison with the Korean recommended varieties, 4, When the female brown planthopper adults were caged on Tong-il variety (Suwon 214) and the resistant variety Karsamba ASD-7 separately, greater number of eggs were observed on Suwon 214 and less on Karsamba ASD-7, while when two varieties Suwon 214 and Karsamba ASD-7 were given together in the same cage, Karsamba ASD-7 was much more prefered for oviposition to Suwon 214. 5. There was no difference in e99 Periods and their hatchal\bility between the resistant and susceptible varieties, but nymphal periods, rate of adult emergence, longevity of the adult, and its fecundity were significantly different according to the varieties.
