The green leaf \\eeyi\, PhyUobius viridiaereus,Laic\\.,vra.s found eating 

 the leaves of climbing-roses, and the black vine weevil, Oliorrhjnchus 

 sulcatns, F., injured ferns in June 1915 in Co. Dublin. Caterpillars of 

 the winter moth, Cheimatohia hrumata, L., were also found feeding on 

 rhododendron leaves, a new food-plant. The damage was promptly 

 stopped by spraying with lead arsenate. In November 1914 tulip 

 bulbs destroyed by young caterpillars of a swnft moth., Hepialus sp., 

 were received from Co. Dublin. In June 1914 the hazel weevil, 

 Strophosomns coryli, ¥., was found feeding on larch in Co. Wicklow, 

 and in May 1915, the same species together %nth the leaf weevil, 

 PhyUohius argentatus, was reported from Co. Antrim on the same tree. 

 The best remedy is to shake them off the branches on to cloths or 

 (boards and kill them. If the size of the plantation permits of 

 spraying, an arsenical wash should be tried, as the beetles feed by 

 •devouring the solid leaf-tissue.

The author records the sudden wilting of many plants of his potato 

 •crop early in 1917. This proved to be due to the attacks of a Pyralid, 

 Euzophera osseatella, Tr., which occurs in Egypt, its usual food being 

 the egg-plant, and not, as was feared, to a pest impoii:ed from Cyprus 

 -on the seed potatoes. The larva perforates the stem at the level 

 ■of the soil and bores upwards for about an inch. As soon as the 

 plant begins to wither, it deserts it for another one, ultimately 

 spinning its cocoon in the stem. The adult moth emerges in 15-20 

 clays. The eggs, which are very minute, can be discovered only with 

 .great difficulty and the only remedy seems to be the pulling up of 

 the plants, which should be sprinkled with petrol and burnt.

Early in 1916 some publicity was given to the success attending 

 the experimental treatment of his orchards adopted by a fruit-grower 

 ■against the attacks of the codling moth [Cydia p)omoneUa\. This 

 ■consisted in carefully removing all the soil from the roots of the apple 

 trees for a radius of three feet, and leaving them fully exposed all the 

 winter to the action of frost and rain. In the spring, three kerosene 

 tlnfuls of sheep droppings were spread over the roots and covered 

 with a layer of soil, the result being the complete absence of the moth 

 •over the three acres thus treated. Fearing that this might lead 

 apple-growers to neglect spraying with, lead arsenate, as required by 

 the Fruit Pests Act, the Director of Agriculture arranged that 

 ■comparative tests of the two methods should be carried out on an 

 ■exjjeriment farm. Six trees, treated as above, yielded up to the 

 28th December 1916, 423 moth-infested apples and 13 larvae found 

 in the bandages, while six similar and neighbouring trees that had 

 been sprayed with arsenate of lead yielded 10 living larvae in the 

 .apples, and one in the bandages,.
