Crickets (Gryllus servillei). These insects are sometimes very 

 troublesome in orchards and vineyards, as they eat the bark of the 

 stems and branches, and often to such an extent that the trees are 

 destroyed, or very seriously injured. Trees can. in a large measure, be 

 protected from their ravages by enclosing the trunks with pieces of tin, 

 so as to form smooth sides, up which the insects cannot travel. As a 

 matter of course, no space should be left between the tin and the baTk 

 through which they may crawl. A mixture of soft-soap, sulphur, quassia, 

 and Paris Green or London Purple is a good preventive. Take soft- 

 soap and quassia at the rate of two ounces each to every gallon of water, 

 and add the arsenical poison in the proportion of one ounce to every ten 

 gallons. Paint the trees or vines so that they will receive a good coating. 

 Crickets may also be kept under by poisoning them with a mixture of 

 arsenic and bran sprinkled on the ground. 



Elephant Beetle (Orthorrhinus cylindrirostris). A very destructive 

 insect, belonging to the Weevil family. The perfect insect is dark- 

 brown, marked with patches of greyish-white, and rather less than an 

 inch in length. The grub is yellowish-white, with a reddish-brown 

 head. Great ravages are caused by the insect in its larvae stage, boring 

 into the branches of the Apricot, Peach, Orange, Vine, and other fruit 

 trees or shrubs. Remedies : The only successful method, as far as is 

 known, for checking this pest is hand-picking. Possibly, spraying 

 with some powerful solution might prove useful, as in the case of other 

 borers.
