摘要:

采用果实解剖法以极晚熟野生毛桃为试材,逐期调查田间状态下橘小实蝇在山东地区秋冬季为害率、存在虫态及活性情况,结合当地温度数据,建立逻辑斯蒂拟合曲线,并通过相关性和灰色关联度分析,研究温度与果实内幼虫死亡率关系。利用土壤解剖和罩网法调查橘小实蝇越冬虫态及生存状态情况。结果表明,橘小实蝇在山东地区为害率前期平缓、后期显著增加,表现明显线性特征。随着时间的变化,1龄和2龄幼虫数量逐渐减少,3龄增加,11月23日后1龄幼虫为0,说明成虫产卵行为基本终止。11月16日开始出现死亡,11月23日迅速增加,12月7日死亡率达到100%,表明幼虫无法在果实内越冬。温度各指标间均达到极显著正相关水平,而幼虫死亡率与各温度均达到极显著负相关水平,说明温度极显著影响橘小实蝇幼虫死亡率。通过逻辑斯蒂方程拟合分析可知,山东地区橘小实蝇桃果内幼虫死亡的时间为11月9—17日,该拟合计算与田间实际情况相符。由秋冬季幼虫死亡率与温度指标模拟值灰色关联度可知,外界环境当日最高温度与幼虫死亡率关联度最大,其次为平均温度,而最低温度影响最小。通过对橘小实蝇越冬虫期和年度进化过程研究,认为橘小实蝇在山东地区田间状态下无法越冬,当地发生虫体仍为入侵迁移种群,防治重点应放在外防入侵上。

Abstract:

This study selected late maturing wild peaches as the test material, used the fruit peeling method to investigate the damage rate, insect status, and activity of the Bactrocera dorsalis in the autumn and winter seasons in Shandong Province, combined with local temperature data, established a logistic regression curve. The relationship between temperature and larval mortality rate in the fruit was studied through correlation and gray correlation analysis. The overwintering status and survival status of the B. dorsalis were investigated using soil planing and net covering methods. The results showed that the damage rate of the B. dorsalis in Shandong region was gentle in the early stage and significantly increased in the later stage, exhibiting obvious linear characteristics. The number of 1st and 2nd instar larvae gradually decreased with the time, while the number of 3rd instar larvae increased. After November 23rd, the number of 1st instar larvae reached 0, indicating that the oviposition behavior of adults had basically stopped. Death began on November 16th, rapidly increased on November 23rd, and reached 100% on December 7th, indicating that the larvae were unable to overwinter within the fruit. The temperature indicators have reached a highly significant positive correlation level, while the mortality rate of larvae has reached a highly significant negative correlation level with each temperature, indicating that temperature has a significant impact on the mortality rate of B. dorsalis larvae. According to the logistic equation fitting analysis, it can be concluded that the time of larval death in the peach fruit of the B. dorsalis in Shandong Province is between November 9th and November 17th. This fitting calculation is consistent with the actual situation in the field. Calculating the grey correlation between the mortality rate of autumn and winter larvae and the simulated values of temperature indicators show that the highest temperature in the external environment during autumn and winter has the highest correlation with the mortality rate of larvae, followed by the average temperature, while the lowest temperature has the least impact. By studying the overwintering stage by stage and the annual evolution process of the B. dorsalis, it is believed that the B. dorsalis cannot overwinter in the field in Shandong region, and the local parasites are still invasive and migratory population, the focus of prevention and control should be on external invasion prevention.
