Cycad Aulacaspis scale (Aulacaspis yasumatsui Takagi, 1977) in Mexico and Guatemala a threat to native cycads
Cycad Aulacaspis Scale (Hemiptera: Diaspididae: Aulacaspis yasumatsui Takagi, 1977), which is native to Southeast Asia, is a devastating pest of some species of cycads in areas where it is invasive. In September 2016, it was reported to be present in Chiapas in southern Mexico, a country with 60 native cycad species, most of which are endemic and endangered. Here we report the presence of the pest in 6 additional Mexican states and in Guatemala. Surveys of natural populations and quasinatural sustainable nurseries in 4 states, including Chiapas, find no evidence that the pest has yet spread to natural populations. At present, it appears to be confined to cultivated cycads, presenting a window of opportunity for effective control.
