and leaves only one course by which they can be checked, and this 

 consists of carefully picking all fruit suspected of containing the 

 maggots and destroying it by boiling or burning the fruit, 

 There is scarcely any variety of fruit which this fly does not attack.

Life History. The female fly lays the eggs in the fruit after 

 piercing the fruit with her ovipositor ; the eggs soon hatch, and the 

 maggots grow very rapidly, eating their way to the core of the fruit, 

 and when they have attained their full growth they leave the fruit 

 and enter the soil to pupate. In warm weather they only remain 

 in the pupa stage for about ten days, coining out as flies and imme- 

 diately begin the work of destruction again. Its chief aim in life 

 seems to be the destruction of every fruit that it meets with.
