Mimosa pudica (미모사), Argemone mexicana (멕시코 가시양귀비) Leucus aspara (꿀풀과 일종), Polygonum hydropiper (여뀌), Blumea lacera (국화과 일종) 등 5종의 식물 헥산추출물들의 팥바구미 성충에 대한 살충, 성충우화억제력 및 녹두 종실피해 방제력이 검증되었다. 그 결과, 밭바구미 성충 살충력은 35-69%이었으며, 녹두에 추출물을 처리한 후 성충우화 방제율은 33-63%, 종실 피해 방제율은 13-49%이었다. 추출물의 농도가 증가할수록 살충력, 성충우화 및 종실피해 방제율 등이 증가하는 것으로 나타났다. 이와 같이 5종의 식물 헥산추출물들은 밭바구미 친환경 방제제로 이용가능성이 있을 것으로 판단된다.

This study was conducted with n-hexane extracts of sensitive plant Mimosa pudica, mexican poppy Argemone mexicana, panimarich Leucus aspara, water pepper Polygonum hydropiper and shialmutra Blumea lacera weeds against pulse beetle Callosobruchus chinensis (Coleoptera: Bruchidae) for protection of mung bean Vigna radiata grains. The LC50 values of the weed extracts ranged from 4.5 to 6.4, 4.1 to 5.6 and 3.6 to 5.5 g/100 mL at 24, 48 and 72 hours of post treatment, respectively. The extracts showed 35 to 69% fecundity and 33 to 63% adult emergence inhibitory effect on the pest, and revealed 13 to 49% grain protection of mung beans. Insect mortality, fecundity and adult emergence inhibitory effects, and grain protection activity increased with increased concentration of the extracts. The shialmutra followed by water pepper extracts revealed better performances in fecundity and adult beetle emergence inhibitory effect compared to the other weeds. The findings proved that the n-hexane extracts of the five weeds are sources of botanical insecticides which may be used in the integrated management of C. chinensis.
