deposits an egg in each young fruit selected ; and E. betuleti folds one or more leaves 

 together to form conical homes for the larvae. The remedies for these pests will be 

 found on pages 40 41, Vol. II. Otiorhynchus raucus feeds on the young leaves of 

 pear trees, and the larvae fatten on the roots; for remedies see "Apricot "Weevil," 

 pages 9092, Vol. II. 



Trunk and Branch Infections. Beetles of various species burrow in the stems and 

 limbs of pear trees, especially those parts that have been injured by blows. For 

 description and remedial treatment see pages 263 265, Vol. I. Goat Moth (Cossus 

 ligniperda) larvae occasionally infest the trunks; preventive and remedial measures will 

 be found on page 43, Vol. II. The most prevalent attack made on pear-tree trunks and 

 limbs is that of the larvae of the Leopard Moth (Zeuzera aesculi). The moth is white, 

 semi-translucent on the wings, spotted thickly with lustrous black; larva yellowish 

 white, with glossy black spots, and a blackish head. The larva feeds on the wood, 

 making considerable burrows, and may be destroyed by the methods advised on page 

 43, Vol. II. Eed-belted Clearwing Moth (Sesia rnyopoeformis) larva feeds on the wood 

 of the smaller branches, causing them to collapse suddenly in bad attacks. Preventive 

 and remedial measures are described on page 166, Vol. II. 



Ants, page 255 ; woodlice, page 262 ; earwigs, page 267 ; and wasps, page 279, 

 Vol. I., prey on the fruits of pears.
