Abstract:

The methyl linoleate investigated for their biological activity against Tetranychus cinnabarinus. Slide，dip and Leaf，residue methods were used to measure biological activity. The results indicated that the bioactivity(touch kill, oviposit inhibition, repellency)of methyl linoleate was high , the adjusted mortalities of female mite and egg were 82.82% and 78.54%, Oviposit inhibit ion rate and repellency rate were 78.46% and 95.61%,respectively at the concentration of 5 mg/ml. LC50 is 1.4434mg/ml and 2.0283mg/ml.The test provided theoretical basis for mechanism of the future research.
