 lined, including the removal of the nests of Aporia crataefji and 

 Euproctis chrysorrhoea, and the eggs of Malacosoma neustria, the general 

 cleansing of the orchard and trees from debris, etc., spraying with 

 milk of lime before the swelling of the buds, and the fixing of tanglefoot 

 belts, the two last remedies being directed against Anthonomus 

 pomorum and similar insects. Some information as to sprays and 

 msecticides is also given.

Agriculturists are urged to pay more attention to various spring 

 preventive remedies, which are necessitated by the scarcity of insecti- 

 cides and the present high prices. Trenches should be dug round pea 

 fields, in April, against Sitones lineatus, L., round sugar-beet planta- 

 tions against Bothynoderes {Cleonus) punctivenfris, (Jerm., and romid 

 various crops against Lethrus apterus, Laxm. Mineral manures 

 should be used to diminish the damage from Oscinella [Oscinis] frit, 

 against which trap-crops, preferably of barley, are also suggested.

A large outbreak of Phalera bucephaloides occurred in 1912, which 

 defoliated some 2,700 acres of oak. As outbreaks of this pest usually 

 last for two years, it was expected that it would occur again in 1913. 

 This, however, was not the case, which is beheved to have been due to 

 its having been checked by pheasants. The author records having 

 found the pupae of this moth in the crops of these birds.

The difficulties presented by various remedies suggested for the 

 control of Anthonomus pomorum, none of which fully attain their 

 object, are here dealt with. Trap-belts, which undoubtedly tend to 

 decrease the damage, do not, however, lead to the total destruction 

 of this pest, as many females are able to fly over them to the crowns 

 of the trees. Spraying with pure milk of lime drives away the insects, 

 but in order to be effective, i.e., prevent oviposition, it nmst be done 

 at the moment when the buds separate from one another and when 

 the females are actually ovipositing. A delay in oviposition produced 

 by spraying, if only for two or three days, will delay the emergence of 

 the larvae and thus save the buds. Fruit-growers are invited to test 

 the remedies recommended and to report on the results obtained.
