the eartli; they do not, like the Pea-weevils, remain in the seed or continue 

 their work of destruction. These red larvae may, howver, be found amongst 

 the seed after threshing, but any that we have seen at that time were dead. 

 There is a simple remedy which has been found very effective, that is 

 to cut, or feed off, the first crop of clover by the 15th of June, and thus 

 destroy the maggots before they go into the ground to pupate. The result 

 is that they fail to mature and there are no flies to lay eggs for another 

 brood. The second crop will then produce good clean seed, having the 

 further advantage of many more bumble bees in August than there were 

 in June to assist in the process of fertilizing the bloom. 



Insects Affecting Fruit-Trees. 



In the earlier part of this report there is given an account of the discus- 

 sion of many of the most serious insect pests of the orchard; it is, therefore, 

 unnecessary to refer to them here, except very briefly. Of the scale insects 

 we have as usual received complaints of the Oyster-shell Bark-louse from 

 all over the province. The San Jose scale is reported from Dresden, a new 

 locality; the Curtis and Scurfy scales have been sent in from Simcoe and 

 from Vineland, and no doubt are to be found in many other places, but 

 they are seldom numerous enough to do any serious damage. 



The Pear and Cherry-Tree Slug {Eriocam.pa cerasi) has been very 

 abundant in many places this year; the second brood continuing their 

 injury to the foliage till quite late in the fall. The slimy black or greenish 

 slug-like larvae can be destroyed by dusting with Paris green or lime, or 

 spraying with white hellebore mixed in water. 



Apple-trees in unsprayed orchards in Sandwich, London, Simcoe, 

 Guelph and other places suffered a good deal from the Cigar Case-bearer, 

 the Apple-bud Moth and the Trumpet Leaf-miner. The fruit itself was 

 attacked in many localities apparently by the Snowy Tree-cricket and the 

 Plum Curculio, causing malformations of the apples and a serious impair- 

 ment of their value; the Tussock Worms were also founjd attacking the 

 fruit in a similar manner. Not much attention has been paid to injury 

 from these sources ; it is important therefore that careful observations should 

 be made both as to the insect causing the injury and the time when it is 

 done, in order that intelligent measures may be adopted for prevention. 



Among the small fruits. Strawberry plants have been much damaged 

 by Wire-worms and White-grubs at the roots, especially where they were 

 planted in old pasture fields which had recently been broken up. It is 

 impossible to apply any remedy for the destruction of these underground 

 feeders; the only method of getting rid of them is by a short rotation of 

 crops involving frequent cultivation of the soil and the consequent disturb- 

 ance of the grubs and pupae, as stated in the earlier part of this paper. The 

 Strawberry Weevil has caused some; damage by cutting off the pollen- 

 bearing blossoms and preventing the setting of the fruit. 



The Rose Chafer, which usually appears in swarms about the time that 

 the Grapes are in blossom, has not been so abundant as usual this year, 

 though bad at Cooksville, Niagara Falls, Simcoe and some other places. 



Raspberry and Blackberry bushes have been attacked in some local- 

 ities by the Cane-girdler — a slender beetle, less than half an inch in length, 

 black in colour witji an orange or yellow thorax on which are three black 

 dots. The beetle bites a series of small holes close together all round a 

 cane not very far from the tip, and then makes another series about the 

 length of its own bodv from the first; between these two girdlmgs it 

 excavates a hole and deposits an orange coloured e^^. The grub lives on
