Apple-Tree Insects of Early Spring. (Country Gentleman, for 

 May 7, 1891, Ivi, p. 374:-5, c. 3, 4, 1 — 59 cm.) 



Frequency of insect attacks this season, on unfolding buds, noticed. 

 Insects received from Lansing, N. Y., are the apple aphis, ApMs malt Fabr., 

 and the apple-tree case-bearer, Coleophora malivorella Riley. For the aphis, 

 spray with the soap solution, tobacco water, or kerosene emulsion. The 

 life-history of the case-bearer is given: its remedy is arsenical spraying, at 

 times directed. Larvae of the eye-spotted bud-moth, Tmetocera ocellana 

 (Schiff.), associated with the above. 



From Malcolm, N. Y., the bud-moth larva? and the apple-leaf Bucculatrix, 

 Biwculatrix pomifoliella Clemens, were sent: the best methods for destroy- 

 ing them are given. Operations against them should have been commenced 

 earlier in the season. 



From Lincoln, N. Y., are sent the bud -moth and its larva?: also the pear- 

 tree Psylla, Psylla pyri Schmidb,, the presence of which is indicated by 

 honey-dew; usually occurs on the pear; its apparent increase in our orchards; 

 how to destroy it; its relationship to the Aphididce.

Orange Leaf Trouble. (Country Gentleman, for May 7, 1891, 

 Ivi, p. 375, c. 2, 3 — 11 cm.) 



Spotted and blotched leaves received from Eustis, Florida, and reported as 

 dropping from the tree, show no fungus attack or insect presence. The dis- 

 coloration is not the orange-rust, caused by Typhlodromusoleivorus, but may 

 possibly be owing to an attack of the trees by species of Lecanium or
