BEET WORMS AND THEIR REMEDIES. 1 5 
Aug-. 1G, half of the eggs are hatched and worms are feeding on 
leaves. Last night 38 more eggs were laid. 
Aug. 17, nearly all of the 552 eggs are hatched. 
Aug. 1.8, 14 more eggs laid last night. 
Aug. 21, the eggs laid Aug. 16 have hatched. 
Aug. 22, the eggs laid Aug. 18 have mostly hatched. 
Aug. 22, 1 male moth dies. 
Aug. 24, 100 fresh eggs laid. 
Aug. 25, 1 female moth dies. 
Aug. 29, another female moth dies. Total eggs laid by the two 
females, 704. Time from emergence to laying first eggs, 5 days; to lay¬ 
ing last egg, 1G days. Time required for eggs to hatch, 4 to 5 days. 
The writer was at Palisade, Colo., July 8, 1901, at which 
time the worms were found in all stages of growth upon beets. 
The small worms were usually found in groups of from 3 or 4 to 
6 or 8 beneath slight webs which they spin for protection. These 
worms were most common upon the younger central leaves and 
were more common below than upon the upper surface. The 
webbing continues with this insect until the worms are nearly 
grown. In the early stages of the worms they skeletonize the 
leaves as in the case of the web-worms. Worms taken July 8th 
at Palisade began changing to pupae July 14th. 
REMEDIES. 
When the beets have been gathered it is too late to destroy 
this insect by cultivation, but a thorough stirring of the surface 
soil immediately after the worms disappear would probably de¬ 
stroy many of the pupce in the ground. 
The worms may be destroyed by the use of poisons the same 
as in case of the preceeding species.
