본답후기인 8중-9상순에 걸쳐 끝동매미충 난에 기생하는 기생봉의 종류와 이들의 기생율을 남부 4개 지역에서 재래품종과 통일계통 품종 포장에서 조사한 결과는 다음과 같다. 1. 난에 기생하는 실적으로 Gonatocerus sp. 2종과 Paracentrobia andoi 그리고 Anagrus sp. 1종 등 모두 4종의 난기생봉이 분포하고 있음이 밝혀졌다. 2. 기생율 조사 결과 Gonatocerus sp.의 평균 난괴기생율과 난립기생율은 각각 $58.8\%$와 $41.0\%$였고 Paracentrobia andoi의 경우에는 각각 $6.2\%$와 $5.3\%$로서 Gonatocerus sp.가 Paracentrobia andoi의 기생율 보다 훨씬 높안 우점종을 이루어 있었으며 이들 두 종이 같은 난괴에 혼재하는 율은 $5.4\%$였다.

This study was carried out to investigate the distribution of egg parasitoids from green rice leafhopper, Nephotettix cincticeps Uhler, from the middle of August through the early September in southern rice cultural areas. The results were obtained as follow. 1. Four species of egg parasitoids, Gonatocerus sp. A and B, Paracentrobia andoi and Anagrus sp. are newly recorded from the eggs of green rice leafhopper. 2. Egg parasitism rates of Gonatocerus sp. were varied from $41.0\~73.9\%$ on an egg mass basis and from $29.7\~49.0\%$ on basis of egg. Percent parasitism rates by Paracentrobia andoi were $0\~9.7\%$ on an egg mass basis and from $2.1\~12.6\%$ on basis of egg. Gonatocerus sp. was dominant egg parasitoid in the parasitism rate than Paracentrobia andoi.
