The beetle, Hypohonis ficus, Erichs., is widely spread in Kakhetia. 

 It does not attack fig branches that are quite healthy, probably owing 

 to the poisonous nature of the sap, but only those nijured and 

 weakened in some way. The larval mines are at right angles to those 

 of the adult and at the end of them the larva prepares a cell in which 

 it pupates. The removal of all injured branches is advised. The 

 Pysllid, Hmnotoma ficus, L., was found in large numbers on figs at the 

 end of June, in the adult and nymphal stages ; it also attacks apples. 

 A scale-insect was found underneath the loose bark of old trees ; the 

 larvae of a Cerambycid beetle bores in the smaller branches, and an 

 Aphid attacks the leaves.

This article deals with, the control of a disease of cotton seed, known 

 locally under the name of " tchor," and the nature of which is as yet 

 uncertain, though it is thought that Tetmnychns telarius probably 

 plays an important part in causing it. Reference is made to the work 

 of Parker and McGregor in America which shows that powdering with 

 sulphur is not an effective remedy against T. telarius, a better one 

 being a solution of a paste of wheat-flour.

The author states that, owing to the difficulties of receiving foreign 

 publications and periodicals during the War, this article has been 

 prepared chiefly from information which has appeared on the pages 

 of this Review. It is noted that mechanical methods of controlling 

 locusts, now nearly dispensed with in Russia, are still in use in some 

 countries, as also are contact insecticides, such as soap, tar or kerosene 

 emulsion. Spraying with poison insecticides is becoming practically 

 universal and it is claimed that this method has been best studied 

 and worked out in Russia. Of late great progress has also been made 

 in the use of poisoned baits.

 This Conference took place at the beginning of February 1917 in 

 Tashlvent. Eggs of Dociostaurus {Stauronotus) maroccanus having been 

 discovered over an area exceeding 270,000 acres, a large outbreak is 

 threatened. It was decided to conduct the campaign principally by 

 means of sprayings and also to make extensive use of poisoned baits, 

 all mechanical methods being rejected. The cost of the campaign is 

 estimated at about £130,000.
