Abstract: 【Aim】 Agriphila aeneociliella (Eversmann) has become an important pest in China in recent years, causing sprout deficiency by the larval feeding on the wheat stem, and has a potential threat to wheat. This study seeks to determine the effect of temperature and foods on the growth and development of A. aeneociliella larvae so as to provide a basis for its population monitoring and management. 【Methods】 Under laboratory conditions (photoperiod 14L:10D, RH 70%±15%), the developmental duration and survival rate of A. aeneociliella larvae reared on wheat at a series of temperatures were investigated, and the developmental threshold temperature and effective accumulated temperature were analyzed. The developmental duration and survival rate of A. aeneociliella larvae reared on wheat, maize and artificial diet were monitored at 25±1℃ with a 14L:10D photoperiod in the laboratory. 【Results】 The results showed that the temperature had significant effects on the development of A. aeneociliella. Within the constant temperature ranging from 13 to 29℃, the developmental duration of each stage of A. aeneociliella larvae shortened as the temperature rose gradually. There was no significant difference in the survival rate of larvae at the constant temperatures ranging from 13 to 29℃. However, under the constant temperature of 33℃, the development was suppressed obviously and the larvae died before completing a whole life span. The developmental duration of each instar of larvae (especially 1st-3rd instar larvae) feeding on different diets had significant difference, with the order of that feeding on wheat<that feeding on maize<that feeding on artificial feed. The developmental duration of the 4th-6th instar larvae feeding on wheat and maize had no significant difference, but was significantly lower than that feeding on artificial feed. 【Conclusion】A. aeneociliella has strong temperature adaptability and its developmental duration is significantly influenced by temperature changes. In the current occurrence area, wheat is the most suitable host and A. aeneociliella feeding on maize can also complete the larval growth and development in the laboratory. This study provides theoretical data for estimating the potential occurrence area in China and technical support for forecasting and comprehensively control the population dynamics of A. aeneociliella in the future.
