year. There were two very prolific generations of Eriocampoides 

 limacina, pear and cherry trees being chiefly attacked. Nicotine- 

 soap, especially in combination with hme-sulphur, proved the best 

 spray against the vine moths, Clysia ambiguella and PolycJirosis 

 hotrana. Calcium cyanamide was successfully used against the larvae 

 of the weevil, Otiorrhynchus sulcatus. The vine scale, Pulvinaria vitis, 

 was best dealt with by scrubbing and by spraying with a 10-15 per 

 cent, solution of carbolineum. Both the vine midge, Conkirinia 

 viticola, and the oyster-shell scale, Lepidosaphes ulmi, were present ; 

 the former disappeared when the vines were treated with sulphur. 

 The mite, Eriophyes loewi, occurred in gardens.

This paper is a report of the author's inaugural speech as rector 

 for the year 1916-17 of the Vienna High School for Soil Cultivation. 

 In Prussia banding is adopted against Lymantria monacha, whereas 

 this is not the case in Saxony and Austria ; this is due to adaptation 

 to different food-plants, i.e., the pine in Prussia and the spruce in 

 Saxony and Austria. It was found that in the outbreak of Dendrolimus 

 pini in 1913-14 near Vienna the Tachinid parasite, Blepharipoda 

 scutellata, Desv., played an important role, though it does not do so 

 in north Germany. So far no means are available for combating 

 the scale Eulecaniutn (Lecaniimi) rohiniarum. Dough, which severely 

 injures Robinia planted to prevent the shifting of sandy soil. 



It is very necessary that entomology in Austria should be organised 

 on the lines adopted in the United States, and in recent years in 

 Germany. There should be regular notification of insect injury and 

 remedial measures must be initiated by the State.

This paper is a review of the important instances of the use of 

 bacteria, fungi, insects and predaceous enemies in combating insect 

 pests, and records all such cases as have occurred in Austria.
