6 REPORT ON INJURIOUS INSECTS FOR 1905. 



At the end of June all the bushes were in full leaf, and 

 excepting here and there, where the growing points had been burnt 

 by the lime, they all looked remarkably healthy. 



The remains of the old diseased buds were microscopically 

 examined, but no mites were found, nor could any trace of big buds 

 be discovered on any of the bushes. 



In September, buds were taken from the different bushes, 

 particularly those buds which appeared big or at all irregular in 

 shape. These were carefully treated by what is known as the 

 Nalepa and other methods; numerous slides were made and 

 examined under the microscope, with the following results : 



Row i. Out of a large number of buds examined, only two 

 were found containing mites ; in one there was a single immature 

 specimen, and in the other there were nve examples, also immature.

Row 2. Very few mites were found, but there were more 

 infected buds; the largest number of mites found in a single bud 

 was seven. In all cases the mites were immature. 



Row 3. Here the buds differed very little from those taken 

 from Row 2, only the percentage of infected buds was slightly 

 greater. 



SUMMARY. It is very evident that all the bushes benefited by 

 the application of the lime and sulphur. It would have been better, 

 however, had a little less lime been used (i pt. of lime to 2 pts. of 

 sulphur would probably have acted as well). In the case of those 

 bushes that received a single dusting, the big buds were con- 

 siderably reduced in number, not more than one-quarter of the
