| 2017年6月－7月, 系统调查了树锦鸡儿、甘蒙锦鸡儿、荒漠锦鸡儿和中间锦鸡儿4种植物上第一代柠条种子小蜂种群动态及寄主荚果发育进程。结果表明, 不同寄主植物上的柠条种子小蜂幼虫、蛹、成虫数量有显著性差异, 密度大小依次为: 树锦鸡儿＞中间锦鸡儿＞甘蒙锦鸡儿＞荒漠锦鸡儿。在发生时间动态上, 柠条种子小蜂幼虫、蛹和成虫的数量基本呈现先逐渐上升后下降的趋势, 4种寄主植物上不同虫态的柠条种子小蜂高峰期出现时间各不相同。甘蒙锦鸡儿上的小蜂出现最早, 6月17日幼虫达到高峰期; 中间锦鸡儿上的小蜂出现最晚, 7月2日幼虫高峰期, 7月14日成虫高峰期; 树锦鸡儿与荒漠锦鸡儿居中。柠条种子小蜂发育进程与锦鸡儿植物的荚果发育进程吻合。本文讨论了柠条种子小蜂种群动态与寄主植物的关系, 明确了柠条种子小蜂发生和达到高峰的时间, 为柠条种子小蜂预测预报和综合治理提供依据。 |

| From June to July 2017, the population dynamics of the first generation of Bruchophagus neocaraganae Liao and host plant pod development on four host plants, i.e. Caragana arborescens Lam., C.opulens Kom., C.roborovskyi Kom. and C.intermedia Kuang et H. C.Fu, were systematically investigated. The results showed that there were significant differences in the number of larvae, pupa and adults of B.neocaraganae on different host plants. The order of the pest density was C.arborescens > C.intermedia > C.opulens > C.roborovskyi. In terms of time dynamics, the number of larvae, pupa and adults of B.neoaraganae showed a trend of increasing first and then decreasing. The emergence time of B.neocaraganae at different peaks on the four host plants were different. B.neocaraganae on C.opulens first appeared and reached larvae peak on June 17. B.neocaraganae on C.intermedia appeared the latest, with the peak of larvae on July 2 and the peak of adults on July 14. C.arborescens and C.roborovskyi are in the middle. The development process of B.neocaraganae is consistent with the pod development process of Caragana plants. In this paper, the relationship between population dynamics of B.neocaraganae and host plants was discussed, and the occurrence and peak time of B.neocaraganae was clarified, which provides an important theoretical basis for prediction and comprehensive management of B.neocaraganae. |
