Cardboard impregnated with cedar oil not effective against 
clothes moths.-- Tests conducted by Wallace Colman, Takoma Park, Md., 
with cardboard chests impregnated with cedar oil or cedar chips indi- 
cate that they "are absolutely worthless as protection against clothes 
moths. A piece of uninfested woolen cloth was placed inside each of 
two such closets and two such chests, which were set up inside a 130 
cubic foot closet constructed of wallboard. Adult clothes moths were 
then introduced inside the large closet on August 8, 11, and 16, 19sae 
On September 5 the closets and chests were opened and large numbers 
of adult clothes moths were found inside. The cloth was heavily in— 
fested with clothes moth larvae, which had seriously damaged it. It 
is evident that clothes moth adults can readily pass through the cracks 
of such closets and chests and that they are not sufficiently tight to 
give any protection to clothing against damage by moths." 
The raisin moth.-- H. C. Donohoe, of the Fresno, Calif., labor= 
atory, has obtained records of the infestation of various fruits by the 
raisin moth (Ephestia figulilella Greg.). In first~crop Mission and Adri- 
atic figs he found infestations of 680,000 and 355,000 larvae per dry ton, 
respectively; in Zante grapes ("currants"), an infestation of 192,000 
larvae and pupae per ton; in apples, light infestation; in Santa Rosa 
and in Red Beauty plums on the ground, 992,000 and 576,000 larvae per ary 
ton, respectively; in white nectarines on the ground, 294,000 larvae 
per ton; fallen pears contained 51,000 raisin-moth stages per green ton; 
and fallen apricots, dried under trees, contained 34.6 larvae and pupae 
per fruit, or 5,264,000 per dry ton (pits included), the heaviest field 
infestation recorded in any of the food materials of the raisin moth. 
Mr. Donohoe notes that "recent examinations of a variety of fallen fruits 
exposed to the sun showed no living stages of Ephestia. The infestations 
recorded above were found in fruits collected from shaded locations." 
He "has found that all living larvae in samples of such fruit can be 
caused to leave the material by exposing it ina deep pan to the heat 
of a 100-watt electric light for about 30 minutes." 
Buried traps for dried—fruit beetles.-- Perez Simmons, Fresno, 
reports the results of further trapping of dried-fruit beetles: "Dur-— 
ing the period from August 17 to 24, two beetle traps set on the sur-— 
face in a planting of Adriatic figs captured 70 Carpophilus hemipterus 
L. and 156 miscellaneous Nitidulidae. Two traps buried to the lid un— 
der adjacent trees took 359 C. hemipterus and 579 miscellaneous Niti-— 
dulidae. The advantage of buried traps indicated by previous trials 
iS Supported by these results, which show that lowering the entrance 
of the traps to the surface of the soil is advantageous in hot weather 
as well as in cold weather (March 1933 Monthly Letter, p..6=7 helt
