THE MOSQUITOES OF THE SOUTHEASTERN STATES Wt 
to man. Several types of suction collectors have been used for taking 
specimens alive or in large numbers. 
A pill box, with a thin layer of cotton pressed down into the 
bottom and sides, is convenient for holding or shipping the speci- 
mens. The box should not contain so much cotton that the specimens 
will come in contact with the lid, and if more than a wisp is used 
its weight will cause it to shift about in the box during shipment. 
Cotton should not be placed on top of the specimens. Specimens 
that have been moist- 
ened, crushed, or 
rubbed are usually un- 
satisfactory for iden- 
tification. 
The suction type of 
hght trap, as de- 
veloped by New Jer- 
sey workers, is being 
used extensively for 
obtaining samples of 
the mosquito fauna of 
an area and records of 
the relative abundance 
of different species, 
particularly in con- 
nection with control 
operations. The speci- 
mens captured are 
more or less damaged, 
however, and usually 
unsuitable for the per- 
manent collection. 
The upright model of 
this trap (fig. 6) is de- 
scribed by Mulhern 
C31). 
Adult specimens 
that are to be retained 
in the permanent col- 
lection should be

lining of sheet cork or 
balsa wood. Freshly killed specimens may be mounted on minuten 
pins, and dry specimens on paper points cut from stiff paper (fig. 7). 
In using the paper mount, an entomological pin is passed through the 
base of the narrow paper triangle and a small drop of cement is dabbed 
on the tip of the paper. The paper is then pressed gently onto the side 
of the thorax of the mosquito, with the tip directed toward the 
mesonotum. Care should be taken not to smear the legs or wings 
with the cement. For uniformity the points are usually stuck onto 
the left side of the specimen. A cellulose cement is preferable to
