The caterpillar of Argyresthia illuminateUa infests the ends of the 

 twigs of Abies alba, and lives exclusively on this tree, a fact not 

 previously recorded. The attacked branches may be recognised in 

 the autumn by the slightly yellowish-green colour of the needles. 

 The eggs are laid on the buds at the tip of the twigs ; the buds are 

 eaten, and from this point the whole twig is completely hollowed 

 out. Pupation takes place in these hollow twigs. Natural enemies 

 of the caterpillar include Tchneumonid parasites and birds. 



Argyresthia glabratelki lives only in the buds and ends of of the twigs 

 of Picea excelsa, A. certella exclusively in the end buds of the same 

 tree, and A. laenigatelh in the ends of the twigs of Larix dccidua. All 

 these, as well as A. illuminatella, are found in the spring, while 

 Argyresthia praeeocella, which lives only in the berries of Jnniqierm 

 communis, occurs in September.

Agrotis collina has a wide distribution and was first noted in Saxony 

 in 1908-10. It is hmited to mountainous districts, but is seldom 

 found in the Alps. The caterpillar has been found on raspberry 

 bushes and also in beech- woods of which the undergrowth is composed 

 of wild raspberries. Sainbucas racemosa, Solidago fuchsii and wild 

 lettuce. The caterpillars hide in the dried, roUed-up leaves of these 

 plants and are to lie found in them even in very cold weather. They 

 appear at the beginning of IMay on the young foliage of raspberry 

 bushes and elder trees.

The Hessian fly [Mayetiola destructor], which was very destructive 

 to wheat in 1916. was in 1917 held in check by the numerous parasites 

 that had been observed in the previous season, though the jointworm 

 [Isosoma tritici] seriously injured the wheat crop in some locahties. 

 Aphids were unusually abundant, especially on potatoes. Papaipema 

 viehris {nitela) (stalk borer) seriously injured potatoes, tomatoes and 

 maize. Colaspis brunnea (root-borer) was very active in maize fields, 

 those that had been under timothy grass in the previous year being 

 the worst infested. Potatoes imported into Indianapolis from 

 Australia were found to be badly infested with the potato tuber 

 moth, Phthorimaea operculella, which has not previously occurred 

 in Indiana. Growers were at once warned against this pest.
