| 中文摘要: |
| 近年来,白星花金龟Protaetia brevitarsis Lewis (Coleoptera: Scarabaeidae)已经成为吐鲁番葡萄、桃等果树成熟期的重要害虫。为明确其在吐鲁番葡萄上的发生规律,连续两年调查了新疆吐鲁番亚尔镇白星花金龟成虫的发生时期,并对日活跃高峰期和产卵高峰期进行了分析,同时开展了寄主对白星花金龟成虫繁殖的影响研究。结果表明:白星花金龟成虫在新疆发生时期为5月下旬至10月上旬,发生高峰期为6月中旬;产卵高峰期为7月上中旬;日活跃高峰期有两个,分别为10:00-12:00和16:00-18:00;不同寄主对白星花金龟成虫繁殖的影响不同,该虫单独取食葡萄不产卵,取食番茄、西瓜、桃和杏的成虫繁殖能力高于取食桑葚的试虫。 |

| In recent years, Protaetia brevitarsis Lewis (Coleoptera: Scarabaeidae) has gradually become an important pest of several crops including grape (Vitis vinifera L.) and peach (Amygdalus persica L.) in Xinjiang, China. In order to clarify the occurrence regularity, emergence and peak emergence progress of overwintering adults of P.brevitarsis on grape in Turpan were investigated during 2018-2019, the daily activity and ovulating peak were analyzed, and the effect of different host on the reproduction of adults of P.brevitarsis was carried out. The results showed that the first capture of P.brevitarsis generally appeared in late May, an obvious peak was found in mid-June then dropped back to low levels in September,while no catches in early October. The ovulating peak is early to mid-July, and there are two peaks in daily activity, which are 10:00-12:00 and 16:00-18:00. Host species had a significant effect on the fecundity of P.brevitarsis adults. P.brevitarsis adults reared on Lycopersicon esculentum, Citrullus lanatus, A.persica and A.vulgaris have a higher reproductive capacity than those reared on V. vinifera and Morus alba. |
