| Abstract: | The citrus psylla, Diaphorina citri Kuwayama is not only the vector insect transmitting the yellow shoot disease of citrus but also an important pest infesting the tender shoots on Rutaceae. It has occurred in 15 countyes in the southern part of Zhejiang Province recently. There are 6-7 generations a year in Pingyang, Zhejiang. The adults overwinter on the back of leaves of citrus. Eggs are laid in the bud scales in mid or late March next year. Nymphs appear in early or mid April. First generation adults appear in early May. There are a number of overlapping generations, the adult population reaching a climax during the autumn shoot stage of citrus between July and August. The period of egg stage lasts 3-11 days. Development through the five nymphal instars is completed in 11-36 days. The length of the life cycle from egg to adult lasts 20-67 days. The period of preoviposition is 6-30 days. The sexual ratio of female to male is 1.06 : 1. An individual adult female has a life span of 13-246 days and may produce 172-277.3 eggs on the average in about one month. |
