研究表明,白星花金龟主要分布于新疆北部的4个地州及吐鲁番地区的13县市及其所辖的兵团各农牧团场的农作物和林果种植区。初步确定其主要寄主种类共14科26属29种。初步明确了白星花金龟的田间发生规律,该虫在新疆北部农区一年发生一代,以幼虫在田边有机质含量高的堆肥等处越冬,于翌年5月初化蛹,蛹期30d左右;6月初成虫羽化,6月底达到高峰,其成虫1年出现1～2个高峰,7月中旬成虫开始产卵,至9月初成虫期结束。
Studies have shown that the white beetle beetles are mainly distributed in the four prefectures in northern Xinjiang and the Turpan region 13 counties and their corps under the farming and pastoral groups of crops and fruit growing areas. A total of 29 species, 26 genera, 14 families were initially identified. The occurrence pattern of white-headed beetle in the field was preliminarily clarified. The worm overwintered in the agricultural land in the northern part of Xinjiang for one year. The larva overwintered at composting with high organic matter content in the Tanabe area. At the beginning of the month, adults emerge and reach the peak at the end of June. Their adults show 1 ~ 2 peaks in 1 year. In mid-July, adults begin to spawn until the end of September.
