title: Insecticidal activity of proteinous venom from tentacle of jellyfish Rhopilema esculentum Kishinouye.
abstract: Insecticidal activity of proteinous venom from tentacle of jellyfish Rhopilema esculentum Kishinouye was determined against three pest species, Stephanitis pyri Fabriciusa, Aphis medicaginis Koch, and Myzus persicae Sulzer. R. esculentum full proteinous venom had different insecticidal activity against S. pyri Fabriciusa, A. medicaginis Koch, and M. persicae Sulzer. The 48 h LC50 values were 123.1, 581.6, and 716.3 microg/mL, respectively. Of the three pests, R. esculentum full proteinous venom had the most potent toxicity against S. pyri Fabriciusa, and the corrected mortality recorded at 48 h was 97.86%. So, S. pyri Fabriciusa could be a potential target pest of R. esculentum full proteinous venom.
