摘要:  【目的】明确斑翅果蝇Drosophila suzukii对樱桃Cerasus pseudocerasus的产卵选择性以及与樱桃生理指标的相关性。【方法】测定了斑翅果蝇对4个樱桃品种(黄蜜、红灯、先锋和萨米拖)的产卵选择性,以及各樱桃品种果实的硬度及蛋白质、氨基酸、糖原和果胶的含量,并对各项指标分别进行相关性分析。产卵选择性试验采用完整樱桃供试产卵和切块樱桃诱导产卵两种处理方式,并统计产卵量。【结果】斑翅果蝇对糖原含量较高而果胶含量较低的樱桃(黄蜜和红灯)切块选择性较强。对于带有果皮的完整樱桃,斑翅果蝇的产卵选择性与樱桃果实的硬度有关,在果实硬度小的樱桃品种(先锋和萨米拖)中产卵量较高。但是,斑翅果蝇对樱桃的产卵选择性与樱桃蛋白质和氨基酸含量没有显著相关性。【结论】斑翅果蝇对不同樱桃品种的产卵选择性有显著差异,与其营养物质含量和果实硬度显著相关。

Abstract: 【Aim】 This study aims to understand the oviposition selection of Drosophila suzukii on cherries (Cerasus pseudocerasus) and the relationship of oviposition selection to physiological characteristics of cherry fruits. 【Methods】 The oviposition selection of D. suzukii on four cherry varieties (Huangmi, Hongdeng, Van and Summit) was tested by inducing oviposition of D. suzukii using intact cherry and sliced cherry, respectively. The physiological characteristics of cherry fruits, including the fruit rigidity and the contents of proteins, amino acids, glycogen and pectin, were tested. The correlation between the oviposition selection of D. suzukii and the physiological characteristics of cherry fruits were analyzed. 【Results】 The cherry varieties with higher glycogen content and lower pectin content (Huangmi and Hongdeng) were the most readily chosen hosts for oviposition of D. suzukii. The oviposition selection of D. suzukii on the intact cherry was related to fruit rigidity. The fecundity was higher in the varieties with lower fruit rigidity (Van and Summit). However, there was no significant correlation between the oviposition selection of D. suzukii and the contents of proteins and amino acids in cherry fruits. 【Conclusion】 The selectivity of oviposition of D. suzukii on the four cherry varieties is significantly different, which is related to the nutrient contents and rigidity of cherry fruits.
