INSECT PEST SURVEY BULLETIN 
Vol. 9 April 1, 1929 No. 2 
OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR MARCH, 1929 
In this number of the bulletin is a general review of the Hessian-fly 
situation as it appeared to the investigators of the Bureau of Entomology and 
the State collaborators during the fall and winter months* In general, through- 
out the Middle Atlantic States and the northern part of the East Central States 
the Hessian fly was not unusually abundant. In the southern part of the East 
Central States extending southward over western Kentucky and Tennessee this 
insect was more plentiful. The situation west of the Mississippi Valley is greatl; 
improved over that of last year with the exception of central and southeastern 
Kansas and southwestern, east central, and northeastern Missouri. 
Up to the present time there are no indications from any part of the 
country that the chinch bug is abnormally abundant. 
Reports from Connecticut indicate that the apple aphid ( Aphis pomi DeG. ) 
is likely to be unusually abundant in that State* Similar conditions occur 
in parts of Missouri, 
The California red scale has been found heavily infesting willow and 
nightshade in ravines adjacent to citrus groves in California. These infestations 
are undoubtedly responsible for the difficulty in cleaning up infestations ad- 
joining these ravines. 
Recent recoveries of Coccophagus sp. indicate that this parasite of the 
citrophilus mealybug is able to maintain itself under the winter conditions 
of southern California. 
A tortricid moth ( Amorbia sp. ), probably a new species, has recently been 
reared from material from La Habra Heights, Calif. This insect seriously 
disfigures the fruit of avocado by its galleries. 
The vegetable weevil is reported as causing very serious damage from many 
parts of Mississippi. 
The onion thrips is seriously affecting several hundred acres of onions 
in the Laredo district of Texas. It appears that in this district broccoli 
acts as an alternate host plant for this thrips. 
In the Chadbourn district of North Carolina, slugs are reported as doing 
considerable damage to tobacco in seed beds. This condition has not been ob- 
erved heretofore,
