BULLETIN 5, r. S. DEPAETVIEXT OF AGRICr/LIF/BE. 
As far back in the past as 1SSS the author found larva? of a click- 
beetle. D U s elegans Fab., a close relative of the wireworras. 
under circumstances that led him to suspect that they were feeding 
on the budworcn. Since that time. also, they have been taken in 
association with the larva? of this species and. though never observed 
in the act. it is not at all unlikely that they do feed upon and destroy 
the budworm. Mr. Ainslie also encountered them associated \7itl1 
the budworni in his investigations of the latter at Hurricane. Tenn. 
REMEDIAL AND PREVENTIVE MEASURES. 
After having made its way into the crown of the young corn plant 
there is no remedy for the work of the pest. The shoot is ruined past 
all recovery, and the plant will only throw up worthless " suckers." 
which produce no ears and scant fodder. 
Fertility of the soil, or the lack of this, 
does not appear to have any influence on 
the amount of damage produced. 
Garman * states that of the seriously 
ravaged fields of corn examined by him 
one had been grown to tobacco and an- 
other to oats the previous year, while 
a third had been devoted to corn. The 
ravaged fields observed in Louisiana and 
Arkansas by the author had all been de- 
voted to cotton the previous year. It 
would appear, therefore, that crop rota- 
tion has little if any effect in protecting 
fields of corn from the attack of the larva?. 
In the light of all the information at this time available it would 
seem that the farmer's only hope of relief from the ravages of this 
pest in the cornfields lies in so timing his planting in spring as not 
to subject his crop to severe attack. Quaintance. in central Georgia, 
secured eggs in March and April. 1900; Urbahns found young larvae 
at Mercedes. Tex.. March 1. 1909: George G. Ainslie observed larva? 
attacking oats at Jackson. Miss.. April 20, 1911. The author saw them 
damaging corn at Somerset Landing. La.. April 12. 1SS7. and April 
27. 1555: at Madison. Ark.. May 12. 1SSS. and at Columbia. S. C. 
on May 1. 1906. At the last point the ravages of the larva? were 
equally as serious as had been observed years before at Somerset Land- 
ing. La., and Madison. Ark., but at Columbia the writer was informed 
that corn planted after the middle of May escaped injury from the 
pest. Nearly all of the complaints of injuries from this budworm 
coming to us from the South refer to damage to the crop early in the 
season, March or April, although to the northward early May is
