Trap catches of cigarette beetlés.--W. D. Reed, of the cured tou 
bacco insect investizations at Richmond, Va., revorts that during the 
past season a tabulation of catches of 10 traps operated from May Lh 
to October 30 in 2,610,000 cubic’ feet of Turkish tobacco storage, and 
of 19 traps operated from June 1 to October 31 in 3,393,000 cubic feet 
of domestic flue-cured tobacco storarze, shows that over 2% million 
cigarette beetles (Lasiodérma sérricorne Fab.) were captured. Over 
420 million beetles were captured in the trapping work at Winston-Salem 
end Richmond combined. Large as these catches are, it has not yet been 
determined in what practical way the elimination of so many adults af-— 
‘fects the value of the tobacco. Perhaps the answer is indicated by 
the recent installation by one company of a large vacuum plant for fun 
igating its stocks. ee 
Two-season survival of pea weevil,--Tom Brindley, Moscow, Idaho, 
submitting much cata obtained during the past year on Bruchus pisorun L., 
states that on November: 22, 1933,. he removed from a Ponderosa pine a band 
of 16-mesh screen placed in the .fall of 1931 as a cage around the tree 
near its base. The cage covered an area’ l foot wide and 4 feet in cir-— 
cumference. It had been left undisturbed ‘since placed on the tree and 
while it had sprung slightly by ‘the growth of the tree in one place 
which might have permitted a.weevil to enter, Mr. Brindley considers it 
improbable that a weevil did enter, because a thorough search of the 
bark of the tree revealed no hibernating weevils outside the cage and 
ahalf hour of searching revealed only 8 weevils in adjacent trees. In 
all, 131 dead and 2 living weevils were found in the 4 square feet of 
bark covered by the cage: : This.is interesting, not only because it in- 
dicates the large number of pea weevils that may hibernate in sucha 
small area of bark, but, if the 2 living weevils had survived two grow 
ing seasons, as Mr. Brindley believes likely, it corroborates the data 
reported in October on similar two~season survivals proved to occur in 
warehouses. . 

Developmental period of pea weevil.--A. 0. Larson, Corvallis, Oreg., 
in charge of the pea weevil investigations in Oregon and Idaho, submits 
interesting data on the varying’ longth of time required by certain pea 
weevil specimens to reach maturity. He calls special attention to a 
weevil larva found well’ growm in a Canadian pea 143 days after the seed 
was picked in the field. The seed had remained in its pod under condi- 
tions favorable for development. The average period for development 
from egg to adult was found to be about 5/7 days at Corvallis. 
Webbing clothes moth reared! @n. wheat.--Wallace Colman, Takoma Park, 
Md., reports the very interesting fact that during the past month he 
has reared Tineola biselliella ‘Hun. on commercial wheat germ whichis 
Pectin Vitarnin SS.
