260 The Curculio and Codling Moth. 



opens, the egg hatches, and the young larva commences 

 eating the young leaves, and curling them up, in which he 

 makes his home. They are destroyed by applying the white- 

 wash to the limbs of the tree. The whitewash also kills a 

 very destructive little insect, the eggs of which are contained 

 in little mussel shells, on the bark of the apple and pear trees ; 

 [a species of coccus. — Ed.^ I will communicate the effect 

 of syringing the trees with the wash before the buds break, 

 in July, when the whole effect of the experiment will be 

 known. 



Saxonville, April 22, 1S50. 



Notwithstanding much has been written upon the habits 

 of these two destructive insects, (the curculio and codling 

 moth,) Mr. Simpson's article will be found extremely valuable. 

 His observations have been made with great care, and his 

 experiments, in order to ascertain their various changes, have 

 been conducted with great labor, and perhaps with greater 

 attention than has been bestowed upon them by any previous 

 writer. He has ascertained precisely the time when the cur- 

 culio commences his operations, and the period they continue 

 to destroy the fruit, thus placing it within the means of all to 

 save their entire crop, by attending to the shaking of the trees, 

 the only mode in which we think they can be successfully 

 attacked. Mr. Simpson's experiment of syringing the trees 

 and fruit is well worth trying, and we shall be gratified to 

 lay before our readers the results of this plan after the season 

 is over. 



The codling moth is nearly as destructive to the apple as 

 the curculio to the plum. Any information in regard to the 

 best means of preventing their ravages will be hailed with 

 pleasure by all orchardists. Mr. Simpson's mode is similar to 

 that first described, we believe, by Mr. Joseph Burrelle, of 

 Q,uincy, and published in the New Engla?id Farmer, (Vol. 

 XVHI, p. 398.) 



If such a plan is considered too expensive, or too much 

 trouble to be put into practice in extensive orchards, it cer- 

 tainly is not in small gardens where there are but few trees.
