First record of Psocodea (Psocoptera) on coffee (Coffea canephora) in the Brazilian Amazon (Rondônia state)

ABSTRACT There is much information regarding the association of Psocoptera and coffee as stored grain pests and little is known about their presence in coffee plants. We conducted a survey in a coffee plantation of Coffea canephora in the municipality of Candeias do Jamari, Rondônia state, Brazil, where we obtained the first record of a coffee plant as a host of Psocoptera in the Brazilian Amazon region, and the first record of a representative of the family Archipsocidae (Archipsocus lenkoi) for the state of Rondônia. The psocid population was concentrated and not evenly distributed over the survey area, which indicates an irregular distribution pattern. We have not detected damage or injury to the coffee plants and therefore we cannot consider these psocids as a pest in the coffee plantation.

摘要：现有诸多关于啮虫目（Psocoptera）作为储粮害虫与咖啡豆相关联的研究记载，但针对其在咖啡植株上的存在情况却知之甚少。本研究于巴西朗多尼亚州坎迪亚斯-杜雅马里市镇的罗布斯塔咖啡（Coffea canephora）种植园开展调查，首次记录到巴西亚马逊地区的咖啡植株作为啮虫目昆虫的寄主，同时也是朗多尼亚州首次记录卷啮虫科（Archipsocidae）物种莱恩卷啮虫（Archipsocus lenkoi）的存在。调查区域内的啮虫种群呈聚集分布，并非均匀分布，表明其种群空间分布格局为非均匀型。本次调查未发现咖啡植株受到该类啮虫的危害，因此无法将其认定为该咖啡种植园的害虫。
