A These plants will bear investigation as possible sources of
A infestation of new plantings of strawberries, but inspection of
¤ the plantings about Bowling Green made by the author in .
October, indicates that in the great majority of eases at the l
present time, infestation has come either from old, infested
, beds adjoining new plantings, in which case it is easy to ob-
serve the gradual spread of the pest across the new pla11tings,
or else the beds have been started from infested beds, in which
Q case plants containing the grubs may be found scattered over
i the new beds during the first season.
i SUGGESTIONS FOR TREATMENT.
` Some details relative to the time at which beetles leave the
plants in the fall and return to them again in the spring for
; egg-laying have yet to be determined, but the life-liistory as
` roughly outlined above can be depended on as a guide in prac-
tis. Practis based upon this knowledge has been employed with
I good effect for many years in ordinary Kentucky nurseries in
4 suppressing the pest in plantings of strawberries l`l'()lll whieh
plants were to be sold.
1 Based upon this experienee_ the following suggestions are
, made to growers of strawberries:
Q l. Start new beds as far as praetieable l`ron1 infested
beds—one hundred and fifty yards, or more it` this is feasible.
1 2. ln starting new beds use only young plants l`orme
