We studied the abundance of Brevipalpus spp. in citrus orchards in the Mexican states of Yucatan, Quintana Roo and Campeche. Mites were collected from 100 trees containing a mixture of citrus species where sweet orange was always the main species. Eight collections were made at each location from February 2010 to February 2011. Mites from the genus Brevipalpus were separated from other mites surveyed and their abundance and relationships with the different citrus species were quantified throughout the collection period. A subsample of 25% of the total Brevipalpus mites collected were identified to species level and the interaction of mite species and citrus species were described. Brevipalpus spp. were present on all collection dates and their relative abundance was similar on all citrus species studies. The smallest number of mites collected was during the rainy season. Brevipalpus phoenicis (Geijskes) and Brevipalpus californicus (Banks) were the only two species present and they were found in all locations except Campeche, where only B. phoenicis was present. Yucatan and Campeche are at greater risk of leprosis virus transmission than Quintana Roo because the main vector, B. phoenicis, was more abundant than B. californicus. The implications of our results for the design of more accurate sampling and control methods for Brevipalpus spp. are discussed.
我们研究了尤卡坦州、金塔纳罗奥州和坎佩切州墨西哥柑橘果园中短须螨属的数量。螨类样本采集自100棵包含多种柑橘品种的树，其中甜橙始终是主要品种。从2010年2月至2011年2月，在每个地点进行了八次采集。将短须螨属的螨类与其他被调查的螨类分离，并在整个采集期间对其数量以及与不同柑橘品种的关系进行量化。对所采集的短须螨总数的25%进行了亚种鉴定，并描述了螨类品种与柑橘品种之间的相互作用。在所有采集日期均发现了短须螨属，并且在所有研究的柑橘品种上其相对数量相似。采集到的螨类数量最少的时期是雨季。菲氏短须螨（Geijskes）和加州短须螨（Banks）是仅有的两个品种，除了坎佩切州（仅发现了菲氏短须螨）外，在所有地点均发现了这两个品种。尤卡坦州和坎佩切州比金塔纳罗奥州有更高的麻风病毒传播风险，因为主要传播媒介菲氏短须螨的数量比加州短须螨更多。我们讨论了研究结果对于设计更精确的短须螨属采样和控制方法的意义。
