Abstract:

 [Objectives]  To investigate the oviposition process and the preferred oviposition sites of Diaphorina citri Kuwayama female adults on Citrus reticulate cv. Shatangju bud. [Methods]  The oviposition process of female D. citri was observed and recorded using an apparatus that combined a mobile phone with a macrolens, and preferred oviposition sites on Citrus reticulate cv. Shatangju buds and new leaves were studied by field investigation and laboratory experiments. [Results]  Females preparing for oviposition remained in one place and quivered their antennae. After a while, females either crawled to a suitable site to lay eggs or continued the previous behavior at another site until they found a suitable oviposition site. When females began to lay, their antennae were motionless and their abdomen bent toward the ventral side of body, causing the gap between the epiproct and subgenital plates to gradually open and the ovipositor to be inserted into the oviposition site. After oviposition, females rapidly withdrew their ovipositor; the gap between the epiproct and subgenital plates closed slowly during this process. Females tended to lay eggs in unexpanded and partially-expanded citrus buds in the field. In the laboratory, females also tended to lay eggs in unexpanded and partially-expanded buds of Citrus reticulate cv. Shatangju that were < 10.00 mm in length), and did not choose to lay eggs on new leaves if buds were also available. If only buds or leaves were available, females laid eggs on either new leaves or buds but the amount of eggs laid on new leaves was significantly less than that laid on buds.  [Conclusion]  D. citri females prefer to lay eggs on tender buds of Citrus reticulate cv. Shatangju that are from 0-10 mm long.
