摘要/Abstract

摘要： 【目的】掌握柑橘大实蝇Bactrocera minax对不同品种柑橘的产卵偏好，以及与幼虫取食喜嗜性的关系。【方法】我们用五点取样法分别调查了自然条件下不同品种柑橘果园的虫果率，统计了各品种柑橘虫果基半部和端半部产卵痕量和卵量，并在实验室内采用培养皿桔瓣选择法研究了其幼虫对不同柑橘品种果实的取食选择。【结果】在未采取防控措施的情况下，果树面朝杂树林的方位虫果率显著高于其他方位；同一片受害柑橘园内，不同柑橘品种的虫果率为脐橙Citrus sinensis cv. Navel、酸橙C. aurantium＞冰糖橙C. sinensis cv. Bingtang、天草(Amakusa)、蜜橘C. reticulata cv. Satsuma＞沙田柚C. maxima cv. Shatian＞椪柑C. reticulata cv. Ponkan；柑橘大实蝇产卵痕数和卵量均为橙类（脐橙、酸橙和冰糖橙）大于橘类（天草、蜜橘和椪柑）和沙田柚（P＜0.05）；除蜜橘外，所调查的其他柑橘品种端半部的产卵痕数显著多于基半部（P＜0.05）；幼虫对不同品种柑橘橘瓣肉的取食选择顺序依次为：脐橙、酸橙＞冰糖橙＞天草、南橘C. reticulata cv. Nanju＞蜜橘＞椪柑＞沙田柚。【结论】结果提示，柑橘大实蝇成虫偏向于选择幼虫所喜嗜的橙类品种产卵，且产卵量更多。

Abstract: 【Aim】 This study aims to understand the preference of Bactrocera minax for several citrus varieties. 【Methods】 We investigated the diseased citrus ratio of different citrus varieties in citrus orchards under natural conditions by five-point sampling method, counted the numbers of egg-laying marks and eggs laid on the basal hemisphere and distal hemisphere of citrus fruit, and examined the larval feeding preference of B. minax to host odorants of citrus petals by the selection tests in the laboratory. 【Results】 The results showed that the rate of oviposition sites on citrus fruits facing the forest harborage was significantly higher than that at any other directions in citrus orchards, and the oviposition preference of B. minax found was Citrus sinensis cv. Navel and C. aurantium>C. sinensis cv. Bingtang, Amakusa, and C. reticulata cv. Satsuma>C. maxima cv. Shatian>C. reticulata cv. Ponkan. The numbers of egg-laying marks and eggs laid on oranges (C. sinensis cv. Navel, C. aurantium and C. sinensis cv. Bingtang) were higher than those on tangerines (Amakusa, C. reticulata cv. Satsuma, C. reticulata cv. Ponkan) and C. maxima cv. Shatian (P<0.05). The number of egg-laying marks on the distal hemisphere of citrus fruit was significantly than that on the basal hemisphere (P＜0.05）(except C. reticulata cv. Satsuma). Larval feeding preference was closely correlated with adult oviposition preference. 【Conclusion】 Our results suggest that oviposition preference of B. minax is related to larval feeding preferences.
