This report covers the years 1913 and 1914 and deals shortly with 

 the work done during this time, a full report on the scientific studies 

 •of insect pests of Trancaucasia being in the course of preparation. 

 Special attention was paid to Heliothis obsoleta (arniigera) and H. 

 peltigeru, a large outbreak of which occurred in 1914, and to their 

 parasites, as well as to Cydia j)omonella and its parasite Apanteles sp. . 

 Chionaspis euonymi, and several other pests. In the autumn of 

 1913, lectures on pests and their control were arranged.

In 1914 specimens of Lygxs spinolae, Mg., were received from soutli 

 Tyrol, where this insect was injuring grape-vines, and in April 1916, 

 Lygtis pratensis (tarnished plant-bug) was sent in from the vine- 

 ;growing districts in Styria, where it occurs everywhere, though it 

 .apparently prefers well-manured stocks in the first or second year after 

 manuring. This bug does considerable damage to the foliage of vines 

 and severe infestation may cause the very young leaves to wither entirely. 

 Clean culture and the removal of all rubbish, etc., which may afford 

 shelter in winter, appear to be the most important control measures.

In the Gorizia district the Chalcid, ProspaJtella berlesei, has controlled 

 Aidacaspis pentagona sufficiently to render the introduction of the 

 Coccinellid, Rhizohius lophantae, superfluous. Both the first and second 

 generations of Clysia ambigiieUa were scarce in the vineyards, which 

 were heavily infested with Byctiscus hetidae, Anoniala ohlonga, the 

 larvae of Pergesa {Deilephiht) elpenor, Pidvinaria hetidae and Eide- 

 canium {Lecanium) corni. Fruit trees were attacked by Telephoru.t 

 {Cantharis) fitscus, prunes by Neurotoma flaviventris, and prunes and 

 cherries by Eriocam.poides limacina, which were successfully controlled 

 Avith pow^dered lime and sulphur. Many cherry trees were defoliated 

 by Cheimatobia brumata. Warm water proved an efficient control for 

 Aphelenchus ormerodis infesting chrysanthemums, while carbon 

 bisulphide is not recommended for this purpose. Laurels were 

 attacked by Coccus {Lecanium) hesperidum, Etionymus by Chionaspis 

 euonymiy Robinia by Eulecanium corni and mulberries by E. corni, 

 E. persicae (L. cymbifornie) and Puhinaria hetidae.
