The Apple Bud-moths and Their Control in Nova Scotia. By G. E. 



Sanders and A. G. Dustan. Bull. 16, (Technical Series), Entomological 



Branch, Dept. of Agriculture. March 1, 1919. 39 pp., 14 figs, in text. 



This is a very thorough account of the habits and methods of control of 

 the four commonest and most injurious species of Bud- moths found in the 

 apple orchards of Nova Scotia, viz., the Eye-spotted Bud-moth (Tmetocera 

 ocellana), the Oblique- banded Leaf- roller {Cacoecia rosaceana), the Lesser Bud- 

 moth (Recurvaria nanella) and the Green Bud-moth {Argyroploce consan^uinana) . 



The bud-moths are the most serious orchard insects in Nova Scotia, probably 

 causing more injury to apple orchards than all the other insect enemies com- 

 bined. "It is estimated that in unsprayed or poorly sprayed orchards in Nova 

 Scotia they reduce the crop about 30 per cent. About 75 per cent, of the bud- 

 moths can be destroyed and the crops increased about 22.5 per cent, by two 

 thorough applications of poisoned spray applied before the blossoms open, 

 with a nozzle throwing a coarse driving spray." 



"Open planting and thorough pruning help in the control of the bud- 

 moths by allowing the wind to blow away and destroy many of the adults when 

 they are on the wing in June and July." 



The Eye-spotted Bud-moth is by far the most important of the four species, 

 over 90 per cent, of the larvae infesting buds being usually of this species. 



Considerable difference exists in the susceptibility of different varieties of 

 apple to bud-moth injury, the varieties having wrinkled twigs being almost 

 invariably more heavily infested than those with smooth twigs, owing to the 

 better hibernating quarters offered by the former to the half-grown larvae. 



Accurate data are given on the injuries to the buds and set of fruit, e. g., 

 the exact reduction in the set as determined by counts of infested blossom clusters 

 in the same variety of apple in the same orchard; the comparative size of the
