A short account is given of the relation between meteorological 

 conditions and outbreaks of insect pests. In view of the importance 

 of this matter as a means of being able to predict the possibilities of 

 outbreaks, all persons concerned are requested to send any observations 

 on these points to the Entomological Bureau.

The most serious pest of strawberries is the larva of Melolontha- 

 melolontha, which prefers their roots to those of all other plants, 

 except salad ; the latter is therefore sown among strawberries 

 as a trap crop. Other pests of strawberries are Euxoa segetum, 

 Phytometra (Plusia) gamma, Acronycta nimicis, Anthonomus rubi 

 and Otiorrhynchus sulcatus. 



Pests of currants include Pteronus ribesii {Nematus ventricosus),. 

 Aphis ribis, A. pomi (mali), which can be controlled by spraying with 

 kerosene emulsion or quassia, Aegeria (Sesia) tipuliformis, Tham- 

 nonoma (Fidonia) wavaria, and Lepidosaphes ulmi {Coccus conchi- 

 forniis). 



Gooseberries are attacked by Pteronus ribesii, Aphis grossulariaCy 

 and Abraxas grossulariata. 



Raspberries are injured by Byturus tomentosus, Anthonomus rubi, 

 Peniatoma baccarum, P. bicolor, Sesia hylaeiformis, Aristotelia {Gelechia} 

 micella, which oviposits underneath the bark of the young shoots,. 

 Malacosoma (Gastropacha) neustria and Larentia {Geometra) albicillata.

Owing to the Entomologist having been called to the colours, the 

 Entomological Branch of the Station was closed, and only some 

 scattered information on insect pests is given in this Bulletin. Citrus- 

 plants suffered heavily from Aspidiotus citri [sic] and other scale- 

 insects. Spraying with quassia, tobacco extract, carbolic emulsion,. 

 Paris green and kerosene emulsion was carried out, but only the last- 

 named, when used at a strength of 10 per cent., was effective.
