In order to assess the life history of E. ovalis feeding on Ixora chinensis Lam. pollen, Vigna unguiculata (Linn.) Walp pollen, Hibiscus rosa-sinensis pollen, Acacia confusa pollen, Gossypium spp. pollen and Zea mays Linn. sp. pollen, we compared the developmental periods, survival rate, total egg production and the life history parameters of E. ovalis. The results showed that the growth and reproduction of E. ovalis was achieved by feeding on the six kinds of pollen. Among them, the shortest developmental period (5.07±0.06) d, the highest survival rate 93.75%±3.05%, the highest net reproductive rate 16.78±1.22, and the second biggest total egg production 32.33±2.17 were found when feeding on V. unguiculata under the condition of (25±1) ℃, RH 70%±5%, L∶D=13∶11. The results showed that the pollen of V. unguiculata was more suitable for the growth and reproduction of E. ovalis.
