suggested b$ the inquirer, would prevent cut-worm attack, but not 

 worms. The best preventive in infested ii*'M> is starving out by cro] 

 buckwheat or pease. A good preventive is. preparing d corn with soft 



soap and plaster according to directions given: this method has been 



successful. Soaking the seed corn in kerosene for twenty-four hours before 

 planting might be tried. 



Destructive t<> Pears. A Pesl Discovered in a Catskill Orchard. 



(Albany Evening Journal, for May 30, L891, p. 8, c. 1—17 cm.) 

 The Diplosis pyrivora. (The Sun [New York], June 1, L891, 



p. 3. c. 5 — cm.) 



An insect destroying almost the entire crop of Lawrence pears and attack- 

 ing other varieties is discovered in the Catskill orchards. It is an European 

 insect, first observed in this country at Meriden, Conn., in 1881. This is its 

 second known locality in the United States. Its life-history is given. Can 

 not be reached by the ordinary insecticides. The danger apprehended from 

 its spread. Picking the infested fruit and burning it, recommended. 



Insect Pests. (Oswego Daily Times, for June 2, 1891, vol. 49, p. 

 4. c. 2 — 12 cm.) 



Contains notice of a new case-worm or Coleophora feeding on apple leaves ; 

 the eye-spotted bud-worm. Tmetocera ocellana ; the cocoons of the apple- 

 tree Buccalatrix, B. pomifoliella; and of Aspidisca splendor if erella in its 

 case: together with remedies for the several pests. 



Another Formidable Insect Pest. (Oswego Daily Times, for 



June 3, 1S91, vol. 49, p. 5, c. 2, 3 — 50 cm.) 



The pear-midge, Diplosis pyrivora. discovered at Catskill, N. Y., hitherto 

 known only at Meriden, Conn., where it was introduced about 1880. Infest- 

 the Lawrence pear and other species named; how it affects the fruit; not 

 within reach of insecticides: its life.-history; importance of its control; 

 recommendation to pick and burn the infested fruit; other methods that 

 may be effective against it; amount of injury done. 



Melon and Strawberry Pests. (Country Gentleman, for June 4, 

 1891, lvi, p. 457, c. 2, 3 — IS cm.) 



A request from "Wellhanrs Crossroads, Md., for a remedy for " lice" destroy- 

 ing melons and cucumbers, is answered by recommending the application 

 of kerosene emulsion, pyrethrum in powder or in water, or strong tobacco 

 water — the insect probably being Aphis cuciimeris Forbes. The Vermorel 

 nozzle would best apply the spray to the aphids on the underside of the 

 leaves. Collecting and burning the dead leaves in autumn would doubtless 

 destroy many of the eggs of the aphis. 



The insect injuring strawberry plants by puncturing the stems [no 

 specimens sent] is probably the flea-like negro-bug, Corimelcena pulicaria 

 Germ. It is difficult of control from its large number of food-plants. The 

 applications recommended for the aphis would probably kill it.
