two or three weeks earlier than the main crop. The ears from the 

 trap-crop should be gathered with the husks within six weeks after 

 the maize reaches the roasting ear stage. 



A few naphthaline balls should be placed on the top of the stored 

 grain (1 lb. per 20 sq. ft. of area). This does not affect the feeding 

 value or germination of the grain.

The first generation of the grass worm {Laphygma fmgiperda) was 

 reported early in June. The first and second broods occurred chiefly 

 on land that had been flooded in December 1919 and the early spring 

 of 1920. The second generation, which was unexpectedly large, did 

 severe damage to young maize in July, and a large amount of lead 

 arsenate and calcium arsenate was used. The grass lands of the 

 western section of Alabama suffered most from attacks by the third 

 generation, but on the whole it was not so serious on maize. The fourth 

 generation was largely reduced by parasitic enemies.

 Agric. Expt. Sta., Knoxville, Bull. 123, April 1921, p. 19. 



Japanese clover {Lespedeza striata), the cultivation of which in 

 Tennessee is here described, is seldom attacked by insects, fungi 

 or bacterial diseases. Grasshoppers cause only slight damage. The 

 larva of the smoky crane fly ( Tipula infuscata) is common in 

 Madison County, but has only once been known to destroy a field of 

 this clover.

 on Teak in Zigon and Tharrawaddy Divisions in 1920.— Ind. 



Forester, Allahabad, xlvii, no. 5, May 1921, pp. 209-213. 



In August and September 1920 both mature and young teak trees 

 were heavily attacked by Pyrausta machoeralis in the above districts, 

 and crows {Corvus macrorhynchus) were found to be feeding on the 

 larvae. Severe damage is caused if saplings are attacked when 

 growth of the main shoot is active, because the leader is killed. Pure 

 teak plantations .sufter more heavily than mixed forests.
