Pangola grass - originally from South Africa - is now the big thing in central Brazil. Introduced a few years ago by American foreign aid technicians working under the Alliance for Progress, this remarkable new strain of Pangola grass has been responsible for increasing beef production 2 1/2 to 3 times per acre as compared to the common Bahia grass. The implications for a country like Brazil where food production is lagging behind population growth are clear. The voracious appetite of this tiny ant, and millions like him, can damage the ranges of Pangola grass. Pesticides have been able to control insect attacks on range grass.
