Abstract

|
To determine the effects of newly developed insecticide (Ultra) on Sycamore lace bug (Corythucha ciliata), ten leaf discs were sprayed with the Ultra solution including the other selected commercialized insecticide solutions such as Carbaryl and Pirimicarb, and also with a water-sprayed control. According to the results, the control effect of Ultra on the adults and immatures was respectively 98.9% and 97.5% after 48 hr, and the corresponding values were higher than that of the other tested insecticides (i.e Carbaryl showed 84.6% for adults and 85.6% for immatures; Pirimicarb showed 83.0% for adults and 90.7% for immatures). For the Susceptibility test, LC50 value of Ultra showed the lowest as 1.5ppm, the value of Carbaryl and Pirimicarb were 3.7 ppm and 30.4 ppm, respectively. Therefore, the insecticidal effects were better for the newly developed insecticide than the commercialized insecticides.
