Fryer (J. C. F.). An Insect Harmful to Newly-budded Rose, Apple, 

 and Plum. — Jl. Bd. Agric, London, xxvi, no. 7, October 1914, 

 pp. 636-637. 



During the last two years, a small maggot has caused numerous 

 failures in newly-budded rose, apple and plum stocks. In cases of 

 attack, the bud dies, even after it has become partly welded to the 

 stock, and on examination a number of small bright red maggots 

 are found underneath the bud or under the bark of the stock, where 

 the incision has been made. The pest has been provisionally identified 

 as a gall midge, Clinodiplosis oculiperda, Ruebs., [see this Review, 

 Ser. A, i, p. 424]. In the present paper the use of grafting wax for 

 complete protection of the wound made in the process of budding, is 

 also suggested.

 Scop. — Entom. Mthly. Mag., London, 1, no. 605, October 1914. 



Pteronus ribesi is reported to have been unusually abundant in the 

 neighbourhood of Huddersfield. Gooseberry bushes in widely 

 separated districts of the town were defoliated. In one garden larvae 

 of the second brood were hatching at the time that numerous imagines 

 of Abraxas grossulariata were depositing their eggs, and by the time 

 the larvae hatched, there was little left for them to feed on.

Gryllotalpa gryllotalpa [vulgaris) is a very dangerous pest of market 

 gardens where the soil is sandy or damp, epecially if near water. 

 These insects winter in rich soil and appear in April. They feed on 

 the larvae of insects to some extent, but mostly on roots and stalks 

 of plants, such as cabbage and other vegetables, also fruit trees, grain 

 crops, and even forest trees. The burrows are usually less than 2 inches 

 deep. Oviposition takes place in May in nests situated deeper than 

 the burrows, from 200 to 350 eggs being deposited in each. The 

 young mature and become winged in the second year. The remedies 

 in spring consist in the use of poisoned maize, which must be placed, 

 as soon as the soil thaws, near the spots attacked in the previous year. 

 Two methods of preparing poisoned maize are given: (1) 101b. of 

 maize is boiled in water until it becomes soft, after which the water 

 is poured off and about 2 oz. of white arsenic is added and the whole 

 thoroughly stirred ; (2) 1 lb. of white arsenic is dissolved in water 

 and boiled in the open air with 10 lb. of maize until the maize is soft, 

 water being added when necessary. The grain prepared in this way 

 is buried in the earth, at a depth of about 2 inches and at intervals 

 of about 1 foot. In summer the best plan is to sink a number of pots 

 to their edges in the soil at more or less regular intervals and to connect 

 these with boards set on edge and planted an inch or two below the 

 surface. In this way, the ground is divided into a number oi small 

 areas with a pot at every angle. When the time for oviposition has
