-TERX POTATO FLEA-BEETLE (Epitrix subscrinata) . 



This insect is very troublesome in potato-fields throughout the Province. It 

 also attacks tomato-plants. The adult, which is the destructive form, is a small 

 black-brown beetle, whicji from its characteristic jumping.,powers has been very 

 appropriately named " flea-beetle." There are two broods in a season, the adults of 

 the second generation appearing in the fall. These hybernate and attack the crops 

 in the spring. The greatest amount of damage, however, is done by the summer 

 brood, the adults of which appear about the middle of July. 



Small holes are eaten in the leaf around which the leaf-tissue dies. Very often, 

 also, the early-blight fungus obtains entrance through these injuries. 



TO/. Spraying with Bordeaux mixture alone, as is done against late blight, 

 acts as a deterrent Paris green or arsenate of lead may be added to this to make 

 it more effective, or these may be used alone: 2 to 3 Ib. of arsenate of lead or U Ib. 

 of Paris green should be used to 40 gallons of water. In the latter case % Ib. of 

 freshly slaked lime should be added. Paris green may also be used dry. It should 

 be mixed with land-plaster at the rate of 1 Ib. of Paris green to 20 Ib. of land- 

 plaster. and dusted over the plants in the early morning when the dew is on. In 

 the case of tomato-plants protection may be secured by dipping the whole plant, 

 except the roots, before planting, in a mixture of 1 Ib. arsenate of lead in 10 gallons 

 of water. 



GRASSHOPPERS OR LOCUSTS. 



These pests are often responsible for extensive losses in grain and fodder crops. 

 Truck crops are also attacked and destroyed, and even young orchards may be seri- 

 ously damaged towards the end of summer when the ranges commence to dry up. 

 Such trees may be completely stripped of foliage and of much of their bark by the 

 ecially if they adjoin waste or range land. Eggs are deposited in large 

 numbers where the soil is dry and comparatively free from vegetation, as in old 

 pastures and waste or range land. Egg-laying takes place in late summer or autumn. 

 the young locusts hatching out about May of the following year. 



rol. The Kansas Experiment Station formula is recommended: Bran, 

 20 Ib. ; Paris green or white arsenic. 1 Ib. : n: - quart? : oranges or lemons, 



3 fruits; water, 3% gallons. In preparing the bran-mash the bran and the poison 

 are thoroughly mixed while dry. The juices of the fruit are squeezed into the 

 water, and to this is added the pulp and peal after chopping into fine pieces. The 

 molasses should then be added to the water, and when dissolved the mixture should 

 be poured on to the dry bran and poison, stirring the whole constantly so as to 

 dampen the bran thoroughly. 



The damp mash should be sown broadcast in the infested areas early in the 

 morning ; that is. about the time the locusts are beginning to move about. It should 

 be scattered in such a manner as to cover 5 acres with the amount of bait made by 

 using the quantities of ingredients given in the above formula. Since very little 

 of the bran is eaten after it becomes dry, scattering it broadcast in the morning, 

 and very thinly, places it where the largest number will find it in the shortest time. 

 ie poison bait does not act quickly, it will be from two to four days before the 

 locusts will be found dead, and the bodies will be most numerous in sheltered places. 



THE PEAR-LEAF BLISTER-MITE (Eriophyes pj/rt). 



This mite winters over under the bud-scales of the young wood. As the leaves 

 expand in the spring the adult mites spread over the under-side of the leaves, the 

 females burrowing under the epidermis and depositing their eggs in the burrows. 

 The young larvae feeding in the tissue of the leaves cause malformed growths in the
