An account is given of the life-history of Cydia pomonella, L., as 

 occurring in Bessarabia. The results of observations carried out in 

 1920 and 1921 show that at least two, and under favourable conditions 

 three, generations may occur annually. The larvae hibernate in the 

 cocoon. A list is given of the varieties of apples arranged according 

 to the amount of infestation, which appears to be least severe in the 

 summer varieties. The remedial measures recommended include 

 scraping the bark in early spring or late autumn, spraying with 

 arsenicals, banding and enclosing the fruit in bags.

The Chalcids, Eitpehmis urozonus, Dalm., and Enlophus longuliis_ 



Zett., are recorded from Daciis oleae, Rossi. Ageniaspis fuscicoUis 



praysincola, Silv., infests the olive moth. Prays oleellus, F. 



The measures recommended against Dacus oleae include the planting 

 of olives among other trees. For utilising natural enemies two varieties 

 of olives should be grown — 1 per cent, of the plantation being a variety 

 with early fruit and 99 per cent, a variety with late fruit. All the 

 infested early fruits should be collected on two occasions and stored 

 in boxes that permit the escape of the parasites.

Though generally rare in Germany, Aporia crataegi, L., has caused 



severe losses to fruit growers in the Rhine Palatinate, where it has 



been numerous since 1917. Energetic action organised by the aiithori- 



ties checked the outbreak in the course of the mnter of 1920-21, and
