Among the fruit-tree pests were the following : — Tetranychus sp. 

 and Eriophi/es malinus on apple ; E. tristriatus on walnut ; E. pyri 

 and Epitrimerus pyri on pear ; and Eriophyes padi on plum. The 

 Aphids included Eriosoma (Schizoneura) lanigerum, Aphis mali and 

 A. sorbi on apple ; A. pyri on pear ; and Hyalopterus arunclwis 

 (pruni) on plum. The scale, Lepidosaphes ulmi, was found on apple. 

 The bugs, Orthotylus marginalis and Calocoris biclavatus, are important 

 enemies of the pear, their attacks stunting the fruit and causing it 

 to harden and drop. The larvae should be shaken off the young 

 fruit into pans containing water and petroleum or on to sheets. 

 Spraying with a 3 per cent, solution of soft soap is also useful. The 

 yellow puncture-spots characteristic of injury by Typhlocyha rosae 

 were noticed on apple fohage. A number of complaints referred to 

 injury by the caterpillars of Cydia {Carpocapsa) poynonella, Argyroploce 

 (Olethreutes) variegana, Lyonetia clerJcella, Leucoptera {Cemiostowa} 

 scitella and Hemerophila (Simaethis) pariana. Hyponomeuta mali- 

 nellus occurred on apple, H. padellus on plum, and H. variabilis on 

 Euonymus. Nygmia pJiaeorrhoea, Don. {Euproctis chrysorrhoea) was 

 found on pear leaves. Clieimatobia brumata was a common pest ; 

 some of the Swiss brands of banding glue are satisfactory against it, 

 but require renewing more frequently than the imported material. 

 The caterpillars of Cossus cossus and Zeuzera pyrina and the larvae 

 of Contarinia pyrivora (pear gall midge) and Perrisia {Dasyneura) 

 pyri (pear leaf gall midge) were also sent in. Apple blossom was 

 injured by Anthonomus pomorum. 



Bark-beetles included : — Xyleborus {Anisandrus) dispar in apple, 

 pear and plum ; X. xylographus (saxeseni) and Scolytus (Eccoptogaster) 

 mali in apple ; S. (E.) rugidosus in apple and plum. It was again 

 noted that the plants attacked were those already weakened through 

 other causes. Melolontha melolontha was taken from apple, pear and 

 plum roots. Eriocampoides Umacina injured pear fohage, on which 

 its larvae can be killed by vigorous spraying -wdth a 3 per cent, soap 

 solution. Pupation takes place in the ground beneath the tree and 

 digging up the ground and then treading it down will destroy the 

 majority of the pupae. Neurotomaflaviventris {Lyda pyri) also infested 

 pear foliage. 



Vine pests included Eriophyes vitis, Phyllocoptes vitis, Eulecanium 

 (Lecaniuni) corni, Typhlocyha vitis, the vine- moths, Clysia anibiguella 

 and Polychrosis botrana, and the beetle, Adoxiis (Bro'tnius) obsciiriis. 



Among the garden pests were : — Eidecanium corni on gooseberry 

 and currant, Chionaspis salicis on young ash, Lepidosaphes ulmi on 

 box, and Aulacaspis rosae on rose. The bean aphis, Aphis rumicis, 

 the raspberry aphis, A. idaei, the potato aphis, Rhopalosiphum 

 {Siphonophora) solani, and Aphis salviae from Salvia sp. (sage) were 

 received ; Rhopalosiphum rubi also occurred on raspberry and 

 R. ribis on gooseberry. Phyllaphis fagi on the beech caused the 

 formation of much sooty fungus. Pemphigus bursarius was taken 

 from poplar leaves and salad roots. It sometimes occurs abundantly 

 on the roots of endive and cabbage lettuce, stunting their growth. 

 Migration from the poplar leaves, on which galls are formed, to the 

 salad roots takes place in summer. From a practical point of view 

 the infestation from individuals that have hibernated on salad roots 

 is the more important, but in the case of distant plots infestation
