Comparison of the ovarian development in Diaphorina citri Kuwayama (Hemiptera: Psyllidae) in relation to the leaf age of orange jasmine,Murraya paniculata (L.) Jack

摘要

Ovarian development in Diaphorina citri females that fed on new leaves of Murraya paniculata after eclosion was compared with that of females that fed on mature leaves of M. paniculata. At 3 days after eclosion, no ovarian development was observed ineither the new-leaf or the mature-leaf group. At 5 days after eclosion, 31of 39 (79.5%) females in the new-leaf group had developed ovaries with at least1 mature egg, whereas only1out of 39 (2.5%) females had developed ovaries with at least1mature egg inthe mature-leaf group. The mean number of mature eggs in females in the new-leaf group was also significantly greater than that in the mature-leaf group. A similar trend was observed at 7 days after eclosion. These results suggest that feeding on new leaves promotes ovarian development in D. citri females.
