north— central our’, northwestern Texas have asked for aid in the control of this 
important pest. In southern Oklahoma and in northwestern Texas considerable 
effort is being expended’ by county agents, dairymen, and ranchmen in an attempt 
to control ca.ttle grubs by methods recommended by the Bureau, ahd many other 
livestock owners are using various commercial concoctions in an attempt to 
alleviate the cattle grub situation. (33. W. Lanke, Bureau of Entomology and 
Plant Quarantine, U. S. D. A.) 
CLEAR LAKE GHAT 
In the Lakeport paid Nice area of California the Clear Lake gnat ( Chaoborus 
a-stictopus D. & S.) was more numerous generally during 1940 than in 1939 • 
Status traps took 32 percent more gnats in 1940 than in 1939* The gnat was re- 
ported as much less abundant and annoying at Lake Pillsbury, a small lake 30 
miles north of Clear Lake, than for several - r ears. (A, W. Lindquist, Bureau 
of Entomology and Plant Quarantine, ,'U. S. D. A.) 
SAMDPLIES 
Sandflies had the usual seasonal occurrence of Oulicoides cani thorax Hoff, 
during the spring and autumn months from grass-marsh areas, and the usual 
emergence of £. furons Poe;/ from mangrove and pickleweed marshes. The latter 
reached its highest incidence of the year from January 15 to February 10, de- 
clined about half by April 15, and then reached another peak about June 15» Py 
September 15 the pest was of little economic importance and remained with a low 
incidence from October 1 to December 31» Pyre thrum is being used more generally 
with satisfactory results in treating screens of windows of houses and for pro- 
tecting the arms and faces of persons working in the vicinity of marshes. The 
disease of children, known in the Southeast as sandfly fever, has not been re- 
ported this season, (W, E. Dove, Bureau of Entomology and Plant Quarantine, 
U. S. D. A.) 
HUMAiT PLEA 
Specimens were submitted for the first time from West Virginia, where a 
heavily infested barn was reported at Port Gay, (H. L, Trenblcy, Bureau of 
Entomology and Plant Quarantine, U. S. D. A.) 
LONG-HOSED CATTLE LOUSE 
Heavy infestations of Linognalhus vituli are general, especially in young 
white-faced cattle in northwestern Texas. Ranchmen in some northwestern coun- 
ties claim that 100 percent of their animals wore infested in December 1940. 
Much dipping for the control of this louse is in progress in various western 
Texas counties. In the vicinity of Dallas, and also in eastern Texas, infesta- 
tions arc common, especially in the younger animals. The larger ranches in the 
eastern Texas area are also dipping their ca.ttle extensively for the control of 
this louse. The general abundance of this louse during 1940 was, according to 
reports, somewhat above normal and considerable damage to young stock was re- 
ported, (E. W. Laake, Bureau of Entomology and Plant Quarantine , U. S. D. A,)
