1. Variation in parasitism risk among hosts is a key factor influencing host–parasitoid interactions; however, within‐patch variation (as opposed to between‐patch variation) in parasitism risk has hardly been studied. This study investigated the mechanisms of within‐patch variation in parasitism risk in the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae).

1. 寄主间寄生风险的差异是影响寄主-寄生物相互作用的关键因素；然而，几乎没有研究寄生风险的补丁内变异（与补丁间变异相反）。本研究调查了东方果蝇 Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) 寄生风险的补丁内变异机制。
