【摘要】 从沉香树林间采集被广赤眼蜂寄生的黄野螟卵块，采用清点卵粒法和像素法计算寄生率。单因素方差分析显示，两种方法计算出来的寄生率无显著差异。像素法可以简便、快速、准确地计算出赤眼蜂对黄野螟卵的寄生率，建议在相关研究应用中积极推广。更多还原

【Abstract】 The parasitism rates of the Trichogramma evanescens-parasitized Heortia vitessoides egg masses that collected from Aquilaria sinensis trees were respectively calculated by the two methods of egg counting and pixel analyzing. The one-way ANOVA showed no significant difference between the parasitism rates calculated by the two methods. The method of pixel analyzing can easily,quickly,and accurately calculate the parasitism rate, and it is suggested to be actively promoted in related research applications.更多还原
