Project 4. " Control of squash vine borer." 



Mr. WORTHLEY. 



The work of the past year has developed tentative methods 

 for the control of this insect. Such methods are now to be 

 tried out on a field scale. 



Project .'). " Control of the squash bug." 



]\Ir. WoRTHLEY. 



Up to date, results have been negative, in that some of the 

 control measures usually advised have been shown to be 

 worthless under the conditions tried. Positive results have not 

 been secured. 



Project 6. " Control of insects in a candy factory." 



Professor Fernald and ]\Ir. Worthley. 



This work was initiated at the urgent request of a Massa- 

 chusetts manufacturer who found his product badly infested 

 with certain insects. The problem was that of fumigating to 

 destroy the insect without at the same time injuring the prod- 

 uct of the factory. AVork is completed and results written up, 

 but not prepared for publication. 



Project 7. "Studies of insect outbreaks in various locali- 

 ties." 



Professor Ferxald. 



This project was started a number of years ago, and has 

 been continued through the making of observations year by 

 year. Work this last year was confined to observations on the 

 presence and development of the corn ear worm and seed corn 

 maggot. 



Project 8. "Pest limits in Massachusetts." 



Professor Fernald. 



This project attempts to correlate the presence and develop- 

 ment of certain insect pests with geographical and climatic 

 conditions in the various parts of the State. Of necessity, 

 observations must be continued over a long period of years 

 before the results will have authoritative value.
