This is a report on experiments as to the different kinds of grain 

 in which Calandra granaria can breed and on the influence of high 

 temperature on these weevils. Linseed, hempseed and peas are 

 untouched by them, while they are able to breed in millet, sunflower 

 seed, wheat, barley, oats and buckwheat. Wheat proved to be the 

 grain in which the weevils bred most freely, and their numbers increased 

 in it 16 times between 3rd December 1913 and 17th September 1914. 

 Next to wheat came barley, and then oats, for which the corresponding 

 figures were 10 and 2 ; in buckwheat, the increase amounted only to 

 7 per cent. The amount of grain destroyed of oats, barley and wheat 

 was in the ratio of 1 : 3 : 9. The fact that oats are less damaged is 

 attributed to the nature of the husk, as, when this was removed, they 

 proved to be only slightly less injured than barley and wheat ; the 

 small damage to buckwheat proved to be due to the character of the 

 grain itself. The number of dead beetles bred in grain, from which 

 the husk was removed, was 80 per cent, for buckwheat ; 50 per cent, 

 for oats ; 40 per cent, for barley and 30 per cent, for wheat. It is 

 impossible to give here the corresponding data as regards the effect 

 of heat, as it is not clear whether the temperatures given refer to 

 Celsius or Reaumur.

This report gives a list of pests including : — Anthonomus pomorum 

 L., w^hich destroyed more than half of the crop of apples and pears, 

 about 50 per cent, of the weevils on pear trees being destroyed by a 

 parasite, while other parasites attacked them on apples ; Cydia 

 pomonella, L., attacked apples, pears, apricots and walnuts ; 

 C. {Grapholitha) funebrana, Tr., appeared in April on sloes, while the 

 second generation bred in July and August on plums ; Hyponomeuta. 

 malinellus, Zell., was found on apples and apricots, the adults being 

 on the mng in July in large numbers ; about 50 per cent, of the 

 pupae collected by the author were killed by a Hymenopterous 

 parasite and to a less degree by a Dipteron. An unidentified 

 Lepidopteron injured the flowers of apricots and a Tortricid the leaves 

 of quinces.
