Extract
“When we consider what immense services hymenopteron insects render to agriculture, it is surprising that those states that have spent already such large sums of money to fight noxious insects and that have lost still more through their depredation have never tried to raise ichneumon flies by the million and let them loose wherever there are any insect pests to destroy.” Felix Gillet., Hort. Comm., El Dorado, California, 1882.
