초록

팥바구미 (Callosobruchus chinensis L.)의 산란 선호성 및성장 조사를 위해 6가지 콩과식물 종자인 팥, 흑태, 백태, 서리태, 서목태, 강낭콩을 선택, 실험을 하였다. 각 종자당 산란수는 팥 1.23개, 서목태 1.13개, 서리태 1.05개, 백태 0.69개, 흑태 0.61개로 나타났으며, 둘째 날 (48 h) 최고 산란수, 넷째날 (96 h) 최저 산란을 나타냈다. 유충 성장기간이 기주식물에따라 2배 이상 증가하는 것으로 나타났다. 우화율은 팥, 서리태, 흑태, 백태, 서목태 (83.33%, 28.23%, 27.87%, 20.44%, 11.59%) 순으로 나타났으며, 모든 종자에서 팥과 3배 이상의 차이를 보였다. 성충 수명은 암컷보다 수컷이 대부분 길었고 암컷의 경우 팥 9.43일, 서리태 8.86일, 흑태 7.88일, 백태 7.17일, 서목태 6.80일로 나타났다. 각 성충의 무게는 암수 모두 팥에서 가장 무겁고, 수컷은 서목태, 암컷은 백태에서 최소 무게를 나타냈다. 결과적으로, 팥바구미는 팥 이외의 기주에서는 산란, 우화율, 성충 수명, 성충 무게 감소가 나타났고 반면 우화시기도 지연되었다. 한편 강낭콩에서 산란과우화는 전혀 없었는데 이것은 강낭콩 종피에 산란과 우화 억제물질이 있음을 시사하며, 이러한 물질의 활용으로 콩바구미과 피해를 조절할 수 있을 것으로 여겨진다.

영어초록

To investigate the oviposition preference and development of azuki bean weevil (Callosobruchus chinensis L.), the following six different leguminous seeds were used in this study: red bean (Vigna angularis (Willd.) Ohwi & Ohashi), black soybean (Glycine max (L.) Merr.), soybean (Glycine max (L.) Merr.), seoritae (Glycine max (L.) Merr.), small black bean (Rhynchosia nulubilis) and kidney bean (Phaseolus vulgaris var. humilis Alef.). In the study of oviposition preference, the numbers of eggs per leguminous seed on red bean, black soybean, soybean, seoritae and small black bean were 1.23, 0.61, 0.69, 1.05 and 1.13, respectively. The maximum daily number of eggs was observed at 48 hours and the minimum was at 96 hours. According to each host leguminous seed, developmental time for each host seed was different. The shortest adult emergence time was on red bean (25.27 days). The other five leguminous seeds increased or doubled the adult emergence time. Adult emergence rates feeding on red bean, seoritae, black soybean, soybean, small black bean were 83.33%, 28.23%, 27.87%, 20.44%, and 11.59%, respectively. Emergence rate on red bean was four times higher than the rate on other seeds. The longevity of emerged female adults was almost all longer than that of males. The male adults weighed the lowest of feeding on small black bean. Female adults weighed the lowest of feeding on soybean. Adult weights were the heaviest for both males and females feeding on red bean. As a result, hosts of azuki bean weevil could decrease oviposition rate, emergence rate, adult longevity, and adult weight but increase emergence time. Especially in kidney bean, adult was not completely emerged. No eggs were laid. These results suggest that there might be emergence inhibitors in kidney bean. These imformation might be used to control damages caused by azuki bean weevils.
