The cotton mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae), is a serious invasive species that significantly damages plants of approximately 60 families around the world. It originally from North America and has also been introduced to other continents. Our goals were create current future potential global distribution map for this pest under climate change with MaxEnt software. We tested hypothesis niche conservatism P. by comparing its native in niches on continents using Principal components analyses (PCA) R. potentially suitable habitat non-native ranges presented present paper. results suggested mean temperature wettest quarter driest are most important environmental variables determining solenopsis. found strong evidence shifts realized climatic South Australia due unfilling; however, shift Eurasian owing expansion.
