Fruit Tree Caterpillars. 



IT may be taken as practically certain that there is 

 neither an orchard nor fruit g-arden completely free 

 from some of the various leaf-eating caterpillars. 

 These caterpillars do an enormous amount of damage, 

 and it is to be feared thai fruit growers do not yet fully 

 realize the great effect caterpillars have in reducing the 

 fruit crop and in affecting its quality. One of the 

 commonest and most destructive of the caterpillars is 

 that of the Winter Moth, and for destroj'ing this, as 

 well as all other leaf-eating larvae. Professor Theobald 

 (in his recent book, " Insect Pests of Fruit,") says that 

 Swift's Arsenate of Lead is far the best substance to 

 use. The first spraying should have been done as soon 

 as the leaves and buds appeared, and, sa3-s Professor 

 Theobald, "a second sprajing is often necessarj' in 

 the case of apples and pears — this should not be later 



than ten days after the blossom has fallen, and at this 

 lime any remaining Winter Moth, Mottled Umber, and 

 March Moth larvae are poisoned, and also the Codling 

 Moth prevented, and many other leaf-eating forms at 

 the same time are destroyed." The outstanding 

 advantages of Swift's Arsenate of Lead are the cer- 

 tainty that it will not damage the foliage, as does Paris 

 Green, and that it stays on the leaves for weeks, thus 

 ensuring a poisonous deposit during the time of attack 

 by insects. There has been a very large quantity of 

 Swift's Arsenate of Lead alread}' used this season all 

 over Ireland as the result of the exceptionally good 

 effect which followed its use for the last two or three 

 years in the l.-irge fruit growing districts of the L'niled 

 Kingdom. The sole Irish agent is Mr. D. M. Watson,
