stage lasting about 2 weeks ; the imago gnaws a hole in the wall of 

 the apricot stone and emerges. The females oviposit inside young 

 apricot fruits, one egg being deposited in each ; here the development 

 of the larva proceeds until the middle of the summer. The infested 

 fruits usually fall, but in some cases they remain on the tree till the 

 larvae have matured. This pest may also breed in other stone 

 fruits. Fallen fruits should be collected and burnt in autumn, and 

 the trees sprayed with milk of lime while the fruits are being formed.

This is a report on the work against pests carried out during 1914 

 in the forestries of the government of Tambov. Lophyrus jpini and an 

 undetermined insect [see this Review, Series A, ii, p. 331] infested 

 young pines, up to 12 years old, in the Gorielsk forestry district ; 

 hand-picking was carried out and 1,351,000 of the first-named pest 

 and 183,000 of the second were collected on the 340 acres infested ; 

 the cost of collection amounted to about l()d. per acre. Caterpillars of 

 Rhyacionia {Retinia) appeared in young plantations of oak, birch and 

 occasionally aspen. In the Usmansk forest, the shoots containing the 

 larvae were cut off with sharp scissors, and buried in the earth from 

 2 to 5 feet deep. In the Pushtinsk iorestHylobius ahietis (pine weevil) 

 occurred over some 222 acres. In dealing with Meloloutha, experiments 

 in ploughing the spaces between the lines of trees were carried out ; the 

 results showed an average loss in the ploughed areas from the damage 

 by the larvae to the roots of 10'75 per cent., against 15'37 per cent, in 

 the unploughed areas. Several pests were found in the Borisoglichsk 

 forest. Over 2,100 larvae of a sawfly {Lyda sp.) were present in each 

 5i scjuare yards of ground in a pine plantation ; some of the larvae 

 were infested by Tachinids. The old bark was damaged, as well as 

 the shoots of the current year. Caterpillars of Malacosoma {Gastro- 

 facha) 2nni were also present.

This is a report to the Forestry Committee of the Tambov Board 

 of Agriculture and State Domains. During 1914, Meloloutha were on 

 the wing only in very small numbers, so that all the research work had 

 to be limited to the larvae. Digging operations, accompanied by 

 taking the temperature of each hole at the depth of about 4 inches, 

 indicated that some connection exists between the temperature of the
