Quarantine restrictions are now in force prohibiting the trans- 
portation of the above products, or their containers, outside the limits 
of areas known to be infested, except when duly inspected and found 
to be free of infestation by the European corn borer. The activities 
in connection with the quarantine will be discussed in a separate 
publication. 
TRANSPORTATION OF ADULTS 
No direct evidence has been obtained relative to the transportation 
of the moths on trains, autos, and other vehicles, but it is believed 
that this factor may contribute to the dispersion of the insect. In 
the New England area the waste places adjacent to railroad yards are 
commonly overgrown with favorite weed hosts of the insect, and in 
some instances such weed areas are very heavily infested. It is pos- 
sible that the moths which habitually seek protection from the direct 
sunlight might alight upon cars standing upon these tracks and later 
be carried to distant points. There is the same danger, though per- 
haps to a lesser degree, when autos and other vehicles halt along 
the roads adjacent to infested cornfields and weed areas. In experi- 
mental tests wherein moths were liberated inside an auto during the 
early evening, two moths which alighted upon the outside of the 
machine remained in this position until the auto had traveled dis- 
tances of 3 and 5 miles, respectively, from the starting point. Under 
similar conditions two moths which alighted upon the inside of the 
auto remained in this position until 12 and 19 miles, respectively, had 
been covered. 
GARBAGE 
During the summer and early fall the kitchen garbage from hotels, 
restaurants, private homes, and the like may contain living larvae or 
pupae in ears or cobs of sweet corn, or portions thereof, which have 
been discarded after purchase on account of the presence of the insect. 
Larvae are also frequently present in the husks, silk, undeveloped 
tips and ear stems. These portions are commonly removed from 
sweet -corn ears before cooking and thrown into the swill container. 
Other plant material which frequently harbors the insect and which 
is commonly discarded during preparation for the table include the 
outer stalks of celery, and injured portions of beet tops, rhubarb, 
Swiss chard, spinach, and string beans. Garbage of this character 
may act as a vehicle for the insect, as it is frequently transported 
considerable distances for use as food for pigs or disposal otherwise. 
Under these conditions the larvae may escape en route, or before the 
garbage is disposed of. Corncobs which have been thrown into pig- 
pens, and subsequently removed when cleaning out the pens, have 
been found to contain living larvae. Garbage is sometimes thrown 
into streams or bodies of water which may carry such material long 
distances through the influences of currents, wind, or tide. 
Collections of garbage made during the summer, fall, and spring 
very frequently contain quantities of infested material consisting 
of cornstalks, and the remnants of other crops, flowering plants, 
weeds, and similar plant material which have been collected during 
the process of cleaning up kitchen gardens. This material is usually 
hauled to a public dump, and unless promptly burned or otherwise 
destroyed becomes a source of infestation to the surrounding terri-
