Investigations dealing with Coleoptera 



Alabama, Auburn, — W. E. Hinds. 

 The life history and control of the rice or black weevil, Calandra oryza. 

 Substantial progress. 



Arizona, Phoenix, — -A. W. Morrill. 

 Experiments in the control by means of arsenicals of the "corrupted lady bird" on 

 beans, Epilachna corrupta. 



Comparative life history studies at different elevations within the range of the 

 insect added to the original plan. 

 Green fruit beetle (Allorhina mutabilis) life history, habits and control. 



Good progress with studies of life history and habits. Satisfactory control 

 methods not yet demonstrated. 



Arkansas, Fayetteville, — George G. Becker. 

 Life history, habits and methods of control of Saperda Candida. 



This is really two projects: (1) life history and habits, (2) the measures of 

 control. Substantial progress. 



Australia, Brisbane, Queensland, — A. A. Girault. 

 Investigations of the sugar cane grubs (Scarabeids in general) of Australia. 



Colorado, Fort Collins,— C. P. Gillette. 

 The life history and practicable means of controlling Epilachna corrupta Muls. 

 S. Arthur Johnson in immediate charge. 



Connecticut, New Haven, — -W. E. Britton. 

 The life history, damage and control of the white pine weevil in Connecticut. 

 A beginning made. Studies must reach over a period of several years. 



Illinois, Urbana, — S. A. Forbes. 

 Life history of the species of Lachnosterna (white grubs), the conditions bringing

Louisiana, Baton Rouge, — E. S. Tucker. 

 A study of Diabrotica 12-punctata, particularly in the larval stage, when it is called

The object is to learn particulars that will be an addition to our knowledge of 

 the species. Through complaints of damaged potato tubers, a new habit of 

 the larva has been discovered which makes it an enemy of the potato crops in 

 our wet lands.
