| Abstract | ||
| This study aimed to evaluate the effect of menthol oil, camphor oil and their mixture against the green leafhopper, Empoasca decipiens Paoli (Hemiptera: Cicadellidae) in laboratory and estimation of LC90 to apply it under semi-field condition. The results showed that the mixture of the two oils was more effective than each essential plant oil alone where LC50 was 37.86 ppm while it was 182.34 ppm and 242.80 ppm for menthol oil and camphor oil, respectively. LC90 values were 463.12 ppm, 962.36 ppm and 1128.05 ppm for the mixture, menthol oil, and camphor oil, respectively. When LC90 was applied in the semi-field experiment, also the mixture of camphor and menthol oil was the most effective than each plant oil alone which recorded 50% mortality while menthol oil recorded 41.03 % and camphor oil recorded 35.90%. | ||
