1909.] The Insect and Allied Pests of the Hop. 625 



Millepedes or False Wireworms. 

 (Blanjulus guttulatus, etc.) 



The Millepedes, also known as False Wireworms and as 

 Thousand Legs, are frequently found in large numbers in 

 hop hills. They seem to take up their abode mainly where 

 there has been a certain amount of decay. This they not 

 only increase, but they will, I feel sure, attack sound roots 

 and healthy parts, and are undoubtedly the cause of some 

 loss in hop gardens. They frequently accompany Wireworms. 



The most usual species in hops is the small pinkish Snake 

 Millepede (Blanjulus guttulatus). A large dark species of 

 Julus, usually called Julus londonensis, also occurs, but does 

 little or no harm. 



The Millepedes do not undergo any definite transforma- 

 tion. The young are hatched very like the adult, but they 

 are composed of a few segments, and have three pairs of legs. 

 They can always be distinguished from a Wireworm or other 

 true insect by the legs not all being on the first three 

 segments. 



The females deposit their eggs from December to May 

 under stones, amongst decaying vegetation, and in decaying 

 wood, and also amongst hop roots. 



Fortunately Millepedes can be easily trapped in the same 

 way as Wireworms, but it is best to use partially decayed 

 roots for them. Slices of marrow have proved a most tempt- 

 ing bait. Lime is also obnoxious to them when prong-hoed 

 into the soil. 



The Long-horned Centipede. 

 (Geophilus longicornis, Leach.) 



Miss Ormerod gives some notes on the possible damage 

 done by this myriapod at Temple Laugherne, near Wor- 

 cester, but it is now known that the Centipede is beneficial, 

 as it feeds upon other insects, slugs, &c, in the soil, and does 

 not touch vegetation. 



Nettle-head in Hops. 

 (Heterodera schachtii, Bos.) 



The presence of this Eelworm disease can be recognised 

 by the smaller size of the leaves and their shrunken appear- 



;
