Abstract
The effect of essential oil of Satureja hortensis L. on food consumption, biochemical compounds and digestive and detoxification enzymes activity of lesser mulberry pyralid, Glyphodes pyloalis Walker was investigated. The percentage of feeding inhibition was dose dependent. The S. hortensis essential oil exhibited a significant antifeedant activity at the highest concentration used. The feeding indices such as efficiency of conversion of ingested food (ECI), efficiency of conversion of digested food (ECD), relative growth rate (RGR) and relative consumption rate (RCR) were decreased compared with the control in fifth instar larvae, while approximate digestibility (AD) index increased significantly. Results showed significant decreases in the amount of protein, lipid, carbohydrates and the activity level of α-amylase enzyme in treated larvae with S. hortensis essential oil. The activity level of detoxifying enzymes such as esterase and glutathione S-transferase were significantly affected by S. hortensis essential oil. The results of this study show high deterrence and antifeedant activity of this essential oil which deserves consideration in integrated pest management program.
