roTATo I'KSTS. 

 Mi/ridjunhi in Potatoes. 



Xumbei*s of centipeiles and s»»nie niillej>e«les were sent to the 

 Board lioni Honiton with a note to the ellect that they (the centi- 

 lH?des) wei"e destn>ying the potato crop in that neighhoinho(Ml. 



The Sivlo^uiufriifie were mostly alive in a small tin box, but 

 sevend had been killed by the stronger ones in the box. 



These Scoloi>endridie aie certainly carnivorous and do not seem 

 to be destructive to roots, although Curtis mentions such a hal»it, 

 quoting the following from a conespoudeut : "Mr. ll<n>e attributed 

 the ixitato disease to the attacks of wire-wonns, and also to a small 

 ScoloiHjndi-a which was found in nmiads infesting diseased potatoes 

 at Sttuthend." 



In all ca.<;es where these myriapods are sent as the culprits 

 other }>ests will be found on careful examination. In the box sent 

 iwm Honiton were also the remains of some small JuUiUv which 

 have imtloubtedly l>een the cause of the trouble. The large centi- 

 pedes sent had pro]>ably l)een feeding otf these Julid;e and other 

 animals in the soil. 



With regard to destroying the Julidic, nothing further can 1>e 

 added to the information given on pages 80 and 103. 



Wire-worm [Lacnn mitrinHs^y L.) in Potatoes. 



An insect sent to ihe Board in a |>otato from r.arley, near 

 Bundcy, proved to Ihj the larva of one of the Klateriihe or ('lick 

 lieelles, i.e., a wire-worm — Lucon tniirimts. 



There is unfortunately n(» remedy when wire-wtmn get into the 

 fK»tat«i crop. The field should be ileeply trenched later i»u and a 

 crop of mustard giown afterwards. Stmietimes wire-worm will leave 

 j»otatoes for wurzel and canot, so that slices of either, if pn»cun\ble, 

 might be put here and there ahmg the niws just under the gro\ind 

 and examined eveiy few days, or n»i>c cake may l>e spreail U'tweon 

 the rows, as this class of larva' air very fon«l «»f this as fi»o«l, and 

 wouM probably Ikj dniwn away from the jdants. 



(Mr. Dendman, <»f Wye. tinds that l>eet-r<^)t forms n much more 

 attractive bait than any other root for catching these jMJsts.)
