Pear Insects s; 



The scurfy bark-louse"^ (CJiionaspis furfura) 

 Order — Hemiptera 



The female scales are large, elongated and dirty 

 white; the male scales are small, long and narrow 

 and have three ridges running lengthwise; the fe- 

 male matures toward fall and lays 60 to 80 pur- 

 plish eggs beneath the scale which remain there 

 until the following spring; the female gradually 

 shrivels and dies as she lays her eggs; there is one 

 brood a year; this pest occurs on apple as well as 

 pear, but it is not considered seriously injurious. 



Control — Spray when the eggs are hatching and 

 the young are appearing with nicotine sulphate, i 

 pint to 100 gallons of water with 4 pounds of soap, 

 or with whale-oil soap, i pound in 5 gallons of 

 water. 



The pear midge ^^ (Contarinia pyrivora) 

 Order — Diptera 



The adult insects which resemble miniature mos- 

 quitoes, and are related to the Hessian fly, appear 

 in the spring when the buds are bursting and lay 

 their eggs through the petals and calyx on the an- 

 thers of the unopened flowers; eggs hatch in 4 or 

 5 days; the maggots work their way to the core of 

 the developing pear and eat into the flesh in all di- 

 rections ; they cause the fruit to become misshapen ; 

 when the maggots are full-grown, about June ist, 

 the pears crack open and allow them to escape to 

 the ground, where they change to pupse and remain 

 in the ground all winter; one brood a year; now 

 occurs in Connecticut, New York and New Jersey, 

 being confined to the Hudson River Valley in New 

 York.
