Candidatus Liberibacter asiaticus Jagoueix, Bové, and Garnier (Rhizobiales: Rhizobiaceae) is transmitted by the psyllid Diaphorina citri Kuwayama and putatively causes Huanglongbing disease in citrus. Huanglongbing has reduced yields by 68% relative to pre-disease yields in Florida. Disease management is partly through vector control. Understanding vector biology is essential in this endeavor. Our goal was to document differences in probing behavior linked to sex. Based on both a literature review and our results, we conclude that there is either no effect of sex or that identifying such an effect requires a sample size at least four times larger than standard methodologies. Including both color and sex in statistical models did not improve model performance. Both sex and color are correlated with body size, and body size has not been considered in previous studies on sex in D. citri in terms of probing behavior. An effect of body size was found wherein larger psyllids took longer to reach ingestion behaviors and larger individuals spent more time-ingesting phloem, but these relationships explained little of the variability in these data. We suggest that the effects of sex can be ignored when running EPG experiments on healthy psyllids.

性别，颜色和大小影响黄Dia对瓦伦西亚橙的探测行为。

暂定Liberibacter胭脂Jagoueix，波夫，和卡尼尔（根瘤菌目：根瘤菌科）由木虱发送柑橘木虱Kuwayama并可能导致柑橘黄龙病。与佛罗里达州的疾病前相比，黄龙病的单产降低了68％。疾病管理部分通过媒介控制。在此过程中，了解媒介生物学至关重要。我们的目标是记录与性相关的探测行为的差异。根据文献综述和我们的结果，我们得出结论，要么没有性别影响，要么要确定这种影响需要的样本量至少是标准方法的四倍。在统计模型中包括颜色和性别都不能改善模型性能。性别和肤色都与体型相关，以前的关于柠檬果蝇性别的研究未考虑体型在探究行为方面。发现了一种身体大小的影响，其中较大的木虱需要更长的时间才能达到摄食行为，而较大的个体则花费了更多的耗时韧皮部，但是这些关系很少解释这些数据的可变性。我们建议在健康的木虱上进行EPG实验时，可以忽略性的影响。
