Biology of the pepper weevil.--R. E. Campbell, Alhambra, Calif., 
visited the Washington, D. C., office from January 17 to 28, and re- 
viewed, with the editorial office, the paper on The Biology of the 
Pepper Weevil, by J. C. Elmore and A. C. Davis, the investigations 
on this pest having been conducted under Mr. Campbell's direction. 
This manuscript has been approved by the Bureau for »ublication as a 
Technical Bulletin. It presents a detailed descrition of the various 
Stages of the insect, a complete biology under California conditions, 
deals with host plants and host-plant relations to infestations, and 
gives a complete resume of the tests which have been conducted on 
direct control. The authors advocate cultural »ractices as the best 
measure of control, that is, the cleaning-up of all host plants upon 
which the weevils overwinter. Direct control measures involve a 
residue problem and also the possibility that severe aphid infesta- 
tions may follow such treatments. 
Mr. Campbell also discussed next season's work on the arsenical 
substitute problem as applied to the semiarid region. The principal 
crops involved in this problem in the Southwest are cauliflower, cab- 
bage, and lettuce, 
Larra analis Fab., a parasite of the mole cricket.--A paper on 
L. analis, an important parasite of the mole cricket (Gryllotalpa 
borealis var intermedia) has been completed by ©. E. Smith, of Baton 
Rouge, La., and submitted for publication. 
Principal insect pests of potatoes in the United States and 
their control.--This Bureau has long needed a publication on the im- 
portant pests of potatoes, and J. E. Dudley has prepared and submit- 
ted a paper entitled, The Principal Insect Pests of Potatoes in the 
United States and Their Control. This paver deals extensively with 
the control of the Colorado »otato beetle (Leptinotarsa decemlineata 
Say), the potato leafhopper (Empoasca fabae Harr.), and the potato 
flea beetle (Epitrix cucumeris Harr.) and touches incidentally on 
such other pests as the potato psyllid, wireworms, white grubs, and 
others. With the exception of the illustrations it is now ready for 
submission to the Bureau for approval. 
Flooding soil for the control of wireworms.--The results of ex~ 
periments conducted at Walla Walla, Wash., in flooding soil to con- 
trol wireworms have been placed in manuscript form by the authors, 
M. C. Lane and D. W. Jones, under the title given above and submitted 
for publication.
