[Background] Ophraella communa is an important natural enemy of the invasive weed Ambrosia artemisiifolia. Starvation tolerance of O. communa adults under low temperature and lack of food directly affect overwintering populations.[Method] Survival rate and mortality of O. communa adults at 10℃ were measured under laboratory conditions. The influence of moisture (water, no water), density (one pair of 1 female and 1 male, two pairs of females and males, and 5 pairs), and environmental conditions (adding soil and deadwood) on starvation tolerance of O. communa were also studied.[Result] Average survival time of O. communa adults was (15.23±1.01) days under dry conditions, and (13.33±0.88) days under humid conditions. The influence of moisture on starvation tolerance of O. communa was not significant. The starvation tolerance of O. communa was enhanced with increase in density. Average survival durations of O. communa adults were (11.96±0.57), (13.78±0.60) and (14.81±0.42) days for one pair, two pairs, and five pairs, respectively. Average survival durations of O. communa adults increased to (15.97±1.05) days after adding soil and deadwood.[Conclusion and significance] O. communa adult had high starvation tolerance under low temperature condition, and this ability could ensure partial natural population of the beetle to overwinter safely. Starvation tolerance of O. communa adults under low temperature conditions played an important role in the theory and practice of biological control of A. artemisiifolia.
