1 subiuil below a report of the entomological work done 

 during the past year under Adams and Hatch Funds. 



Adams F\ind Projects — 1, Rice Weevil. 



This project has been continued principalh- in the field. 

 The practicability of utilizing "trap plots" for concentrating 

 the first generation of Calandra and other species so that they 

 may be removed while still in the grain and disposed of in 

 such a manner as to prevent their spread to later maturing 

 corn has been further tested and with satisfactory results. The 

 field study of weevil resistance as shown by various varieties 

 of corn has' been continued. ^Yhatley's Prolific still continues 

 to lead in the desired combination of high yield and sound- 

 ness of grain due to exceptionally good shuck covering. Owing 

 to the great increase in yield in the crop of 1917 and also to 

 the exceptionally cold winter the insect damage to the stored 

 crop of that season was very much less than average through 

 the State. 



2. Arsenate of Lead — Work in this project was resumed 

 using cotton and the boll weevil as experimental subjects. 

 Some eighteen plots located mainly in the southeastern corner 

 of the State where the heaviest infestation was expected, were 

 dusted at various stages of the cotton and for a varying num- 

 ber of applications. The outdoor work was correlated with 

 indoor cage experiments and chemical analyses of all materials 

 used are being made by the Research Chemist. The field which 

 showed the largest increase in yield, apparently due to the 

 treatment, is being given a very close, detailed study. As a 

 whole the results do not yet justify the recommendation of 

 Arsenate of Lead or any other poisons dusting for boll weevil 

 control. 



3. Fumigation — Under this project we have entered a new 

 phase of the work in the treatment of soils for the destruction
