Boll Weevil Is
Actively Breeding In This State. . . Pest Is Found in Columbus, New Hanover and
Brunswick, Though It Is Not Thought Will Spread to Southeastern Counties
Raleigh, Oct. 27—The cotton boll weevil has to date been
found at Tabor, Freeman and Bolton in Columbus county, and on the edge of
Wilmington in New Hanover county, reports Mr. R.W. Leiby, assistant
entomologist at the Agricultural Experiment Station. Since these two counties
are north of Brunswick county the weevil is assumed to be established here
also.
Mr. Leiby, in speaking of the spread of the weevil stated
that the search had been made as far north as Burgaw and Hampstead in Pender
county, and as far west as Chadbourn in Columbus county, but that it had been
located at these points. During the coming weeks continued search will be made
by members of the division of entomology, Department of Agriculture, in an
effort to locate the northern limits of spread of the weevil.
In each case where located, the weevil was found to be
actively breeding. At Wilmington, particularly, half grown grubs of the weevil
were found in the young green squares, which indicate that it had been present
in the State about two weeks before being located. The damage, however, to this
year’s crop will be negligible, since the squares in which the weevil is now
breeding would not mature cotton this season. However, it appears that the
weevil may succeed in maturing a brood this year within the State, and this
will cause greater destruction next year.
It is predicted by Mr. Leiby that the weevil will cause but
little destruction in the southeastern corner of the State next year, but that the
year following, its work will be very strongly in evidence and will cause great
losses to the farmer who depends only upon cotton. Already reports have been
received of the deprecations of the value of cotton land in Columbus county.
This is declared to be untimely by Mr. Leiby, since the best way to beat the
boll weevil is to grow less cotton and more of other crops.
The boll weevil spend the winter in the adult stage. It
produces a number of generations during the year, requiring only 21 days with
favorable conditions to develop from the egg to the adult stage. Winter
weather, therefore, is an important factor in the increase or decrease of the
weevils. But the pest has been known to survive zero weather in Louisiana, and
it is believed that it will readily withstand North Carolina winters.
