New Species Of Bamboo-feeding Plant Lice Found In Costa Rica
Several periods of field work during 2008 have led to the discovery of a new species of bamboo-feeding plant lice in Costa Rica's high-altitude region "Cerro de la Muerte". The discovery was made thanks to molecular data analysis of mitochondrial DNA. The collected records have also increased the overall knowledge of plant lice (one of the most dangerous agricultural pests worldwide) from the region with more that 20%. The study was published in the open access journal ZooKeys.
It is a well established fact that the arthropod fauna, to which plant lice also belong, is abundantly present in the tropical regions. Not so with plant lice, which prefer the temperate climates of the Northern Hemisphere. This has been a bit of a paradox for scientists although it is also known that plant lice diversity increases in high altitude areas, such as mountains and high plateaus. Such is the sampling area visited in Costa Rica: "Cerro de la Muerte", or The Mountain of the Dead, the highest point in the Costa Rican section of the Inter-American Highway.
Plant lice are recognized among the biggest insect pests on agriculture and gardening. From a zoological point of view though, they are very successful organisms, which although present mainly in temperate climates, have the potential to threaten even tropical regions, dedicated to plant cultivation.
