(Parthesia) chrysorrhoea and A])ona crataegi, all of which appear 

 in small numbers. Various Aphids were very numerous and 

 the infested trees were treated with quassia decoction (5 lb. in 27 

 gallons of water). Eriosoma lanigerum was not present, evidently 

 owing to the dry climate. In the orchards Hyponomeuta malinelliis, 

 Cydia pomonella, Epicomelis (Tropinota) hirta and Oxythyrea slictica, 

 occurred. The first two are controlled by spraying the trees imme- 

 diately after blossoming, with Bordeaux liquid and Paris green (about 

 5 oz. of green in 55 gallons of the liquid). The collection and removal 

 of fallen fruit was also carried out against C. pomonella. The two 

 beetle pests are controlled by handpicking and shaking the insects 

 from the trees and burning; them.

The Rozhnov forests, which are the remains of the well known 

 Murom forests, were not looked after in any way until 1848 and they 

 suffered severely from fires, insect pests, etc. In 18-50, after large 

 fires in the preceding years, some 8,600 acres of the forest were attacked 

 by a sawflyand then byScolytid beetles. In 1861 Bupalus piniarius, 

 L., was also observed in the forests, and in the late eighties, when some 

 afforestation works had been undertaken, the soil of the empty spaces 

 in the woods was for the first time reported to be infested with larvae 

 of Melolontha, which destroyed all the new plantations. It was 

 therefore decided to abstain altogether from replanting the empty 

 spaces and to concentrate the afforestation work on fresh cuttings. 

 In 1902, narrow cuttings not more than 105 feet wide from East to 

 West were made, but proved useless. In order to study methods of 

 controlling the larvae of Melolontha, the Forestry Department estab- 

 lished an experimental forestry station, the author being appointed 

 superintendent of it, which post he held for two years, and during this 

 time much attention was paid to the biology of and damage done by 

 this pest. In the Rozhnov forests, these insects do not oviposit either 

 on old waste ground, even when a few scattered deciduous trees are 

 present, or on coulisses from 300 to 350 feet wide, when sheltered by 

 a curtain of wood, but prefer cuttings, whether artificial or natural. He 

 therefore recommended that clearing the plots infested should be given 

 up and that clearings should be made on various selected spots, which 

 aimed at the creation of a curtain of wood round them, the density of 

 which would prevent the cockchafers from ovipositing and at the same 

 time allow the new growth of planted or naturally sown trees. The 

 need for further research in the methods of controlling this pest is 

 urged.
