Attention is drawn to Sarothrus areolatus, a Cynipid parasite 

 of Phorhia lactucae. The adult parasites are found on flower-heads 

 of lettuce in June and July. Both the host-flies and their parasites 

 remain in the puparium throughout the winter, emerging in June of 

 the following year. 



Eennie (J.) & Harvey (E. J.). Nosema apis in Hive Bees. — Scottish 

 Jl. Agric. ii, no. 4, October 1919, pp. 15-36. 



Observations have been made to ascertain the covirse of Nosema 

 apis in artificially infected and naturally infected stock, as well 

 as its relation to Isle-of- Wight disease and mode of transmission. 

 Nosetna apis does not destroy bee colonies in the rapid and virulent 

 manner common in cases of Isle-of- Wight disease, but the yield of 

 honey is considerably diminished. During the summer the presence of 

 the disease will not cause great loss, provided that the queen is healthy 

 and normal reproduction is continued ; should the queen become 

 infected the disease may be expected to spread steadily within the 

 colony as long as she survives, but the frequency with which death of 

 the queen occurs is in striking contrast to her survival in Isle-of -Wight 

 disease. The survival of stock infested with Nosema apis does not 

 imply immunity against Isle-of- Wight disease. 



The chief point about Nosema apis is its weakening effect on the 

 colonv, and should conditions favourable to the development of 

 dysentery arise, it may become seriously pathogenic to bee stocks.
