TOMATO 
GARDEN FI3AK0PPER ( Halticus cltri Ashm. ) 
Mexico A".. '7. Morrill (February 20): In December (up to the 20th) the 
garden fleahopper was more common in this district than during 
any December cf the last four' or five years. Only c ie field 
suffered actual damage in December in the Los Mochis district 
(Puerte -Valley) ,' Sinaloa, Mex. , but several fields of young 
plants had so many of the bugs that the prospects for the crop 
appeared hopeless- By January 15 a marked improvement had occurred 
except in one area not over l/2 mile square; excessive rainfall 
for that season of the year occurred on December 31- This may 
have destroyed many nymphs but could not have been the cause of 
checking of the insects. A slight frost on the morning of January 
2p had no effect on any stages cf the insects even "here plants 
"-ere da- --d. One center of infestation exists and the damage 
to the 192o tomato crop will depend on the success of 
the attempt 10 destroy the bugs in this place and prevent their 
spread. 3 i ahoppers were moce abundant on January 22-29 in the 
Culiacen v" 11:\ than at the same time in the previous four years

account of the destructive rainfall beginning December 31- There 
has been no frost. Tomato plants have been generally weakened by 
excessive soil moisture.
