Results of Dusting Experiments to Control the Blueberry Maggot

In order to meet the standards established by the Food and Drug Administration of the U. S. Department of Agriculture, the production of maggot-free (Rhagoletis pomonella) blueberries for canning purposes in eastern Maine has become virtually a requisite. Experiments conducted during 1931 demonstrated that two applications of calcium arsenate will accomplish this under conditions of moderate infestation, although the insect may not be completely eradicated. Three applications of calcium arsenate will further reduce the maggot infestation, but there is increased danger of excessive arsenical residue. One application of calcium arsenate was found to be inadequate under ordinary circumstances. The calcium arsenate may be diluted with an equal quantity of hydrated lime and remain effective. Copper carbonate used as a dust in one field test reduced the number of maggots 97.11 per cent.

The Blueberry Maggot from an Ecological Viewpoint.

It often happens that fundamental principles of ecology underlie problems of insect control, and in attacking an economic project the entomologist frequently finds himself working more or less in the field of applied ecology. Few instances in economic entomology emphasize broad ecological relationships more distinctly than does the blueberry maggot[*][1] problem. [1]: #fn-1
