Abstract： Herbivore-induced resistance in the plant Populus delttoids and its effect on the moth Clostera anastomosis was investigated under laboratory conditions. Choice experiments indicated that C. anastomosis larvae prefer unbrowsed to browsed leaves. Feeding larvae browsed leaves prolonged their development, greatly increased their mortality rate and significantly reduced their relative growth rate (RGR). Larvae’s efficiency of conversion of digested food (ECD), efficiency of conversion of ingested food (ECI) and relative consumption rate (RCR) also decreased although the difference between browsed and unbrowsed leaves was not significant. Furthermore, browsed leaves also adversely affected the development of pupae and adults, reducing pupal weight, emergence rate and egg production. This study indicates that browsing by C. anastomosis can induce changes in the chemical composition of the leaves of P. deltoide that adversely affect the digestive metabolism and development of C. anastomosis.
