Kaufmann, T. 1977 Hemisarcoptes sp. and biological control of the date palm scale, Parlatoria blanchardi Targioni, in the Sahel region of Niger.. Environmental Entomology 6: 882-884.

Notes: This author concludes that for the biological control of P. blanchardi in Sahel, the use of Hemisarcoptes sp. is more advantageous than Chilocorus bipustulatus due to climatic conditions and more frequent generations per year.
