Some OF the questions Most ire
quently asked on tick eradication are
answered below by Dr. W. H. Dalrym-
pie, of the Department Of Veterinary
science, Louisiana State University:
Why 10 1t necessary to dip cattle
every "a days during the season to
get rid Of the ticks?
Answer. During the wRrm season
Of the year. the average time requIT-
ed BY the tick TO 6ovc.or, from the
small 1arval or seed tick, after at
taching to cattle, until the large re-
male tick natures ard drops to the
ground TO lay her egg, Is abeut -
days. But white % days may be the
average. many ticks mature earlier
than that time. Consequently Il has
been found that the 2I-day dipping
periods DO not catch the earlier-Ela-
turing ticks, which drop off and keep
on making more ticks, thereby delay.
ing the final results. On the other
hand, by dipping cattle every II days,
all Of the ticks that become attached
to them In the intervals are Killed,
because none Of them mature and
drop of before IA days.
How has this information been OBJ
tainsd7

those engaged in the work OF TICK
eradication that, towards the end OF

While with l4day dipping there may
! be na' =. or only very few, with ticks
! on them.
! Then the dipping periods are based
| upon the time required for the ticks
/ to develop on tho cattle and fall eH7
Answer. Precisely so. The adop-
ton Of the 14-day periods is to DO
stroy all of the ticks that have be-
come attached to the cattle IN the In
tervals between dippings, without any
of them having dropped of.
How long. relatively, will It take to
clean a parish, CT section, Of ticks un.
der the 1%day and 2f-day dipping Pc
ie,.c?
Answer. With the full coopere.
ton of everyone interested, the ticks
may be cleaned up in one season ur-
der the 14day periods; while under
the 2t.dcy periods 1t may take two
or three or more seasons, as mas been
the case In number Of parishes.

production?
