DSRNA FOR THE CONTROL OF TETRANYCHUS URTICAE, ACARICIDE COMPOSITION COMPRISING IT, METHOD OF ENHANCING TOXICITY AND CONTROL METHOD FOR TETRANYCHUS URTICAE USING IT

摘要

The present invention relates to a dsRNA fragment capable of controlling Tetranychus urticae by inhibiting gene expression of TCOPB2 and TCOPE and a composition comprising the same, a toxicity enhancing method and a controlling method using the dsRNA fragment and the composition. The dsRNA fragment and the composition of the present invention can be useful for controlling Tetranychus urticae and is possible to replace synthetic pesticides due to inducing mortality of Tetranychus urticae by disrupting the expression of TCOPB2 and TCOPE when entering a body of Tetranychus urticae through eating.
