GryUotalpa gryllotalpa is mentioned as a serious danger to grafting, 

 as it feeds on the roots of the wild stocks. Against aphids, washing 

 the bushes, especially the budded parts, with green soap is recom- 

 mended. About 1| lb. of soap in 3 gallons of water, well stirred with 

 a brush or a bundle of twigs so as to obtain a lather, makes a good 

 wash.

Some of the fruit-growers in the Crimea now use California mixture 

 [see this Review, Ser. A, ii, p. 209-210], instead of other fungicides and 

 insecticides, such as Bordeaux mixture, tobacco extract, etc., owing 

 to the good results obtained with it. In the campaign against 

 Hyponomeuta malinellus, Cydia pomonella, etc., about 5 ozs. of Paris 

 green are usually added to 27 gallons of this liquid.

It is stated that nurseries and orchards situated in open " steppe " 

 localities, where no forests exist in the neighbourhood, are rarely 

 subject to attack from larvae of Melolontha, or if attacked, the damage 

 done is very slight ; on the contrary, where orchards or nurseries are 

 situated close to forests, especially those containing maple and ash 

 trees, which serve as food for the imagines, the damage is serious. 

 In the presence of these two trees, the orchards and nurseries suffer 

 even when situated at a distance of as much as two miles from them, 

 and it is considered useless to attempt to plant orchards in such cases. 

 The larvae destroy the roots of the stocks, and of bush-fruit, especially 

 raspberries and strawberries, as well as beet and potatoes. In the 

 case of potatoes, recent manuring with dung aggravates the evil. 



The author has unsuccessfully tried fumigation during the jtime 

 when the imagines are on the wing, so as to prevent them from ovi- 

 positing ; nor has he obtained favourable results by keeping the seed- 

 lings for some time before planting in soil containing kerosene and 

 in watering the spaces between the beds with water containing 

 kerosene. The digging out of the attacked stocks, followed by the 

 hand-picking of the larvae, as well as poisoning the larvae with baits 

 consisting of buried grains of maize poisoned with corrosive 

 sublimate, were also not effective ; potatoes planted between the trees 

 in the nurseries were not of much use as traps, although they 

 attracted some of the larvae.
