GuKNEY (W. B.). Spraying for Thrips.— ^^nc. Gaz. N.S.W., Sydney, 

 XXV, no. 9, September 1914, p. 821. 



Apple and pear blossoms should be sprayed against thrips with 

 tobacco wash [see this Review, Ser. A, ii, p. 705] prepared as follows : 

 Steep 1 lb. of tobacco refuse overnight in a gallon of water ; strain 

 off the liquid in the morning, and add J lb. soft soap with a gallon of 

 hot water ; apply while still warm, though not hot. The addition of 

 the soft soap will be an advantage in the first spraying, as it makes 

 the tobacco adhere better, but should be used more sparingly in 

 later applications to the open blooms.

In September, spraying vigorously with tobacco solution to destroy 

 the peach aphis, A2yhis amygdali, Fons., and against the rose-scale, 

 Auhcaspis rosae, Bouche, with lime-sulphur wash or kerosene 

 emulsion, is recommended.

The follo\ving precautionary measures against Mayetiola destructor, 

 Say, are advised : — The soil should be well prepared and sown im- 

 mediately after the first frost, provided it is not earlier than the third 

 week of September. This applies to S. Pennsylvania ; more northward 

 or at higher elevations it may be proportionately earUer.

 Carolina. — Canadian Entomologist, London, Ont., xlvi, no. 9, 

 September 1914, pp. 306-308, 1 fig., 2 tables. 



Species of Chrysopa in cotton fields usually pupate in the apical 

 buds at the terminal portion of the stalk. The pubescence of the 

 foliage at this point has a greyish appearance, which the cocoon much 

 resembles. Several lots of Chrysopa cocoons were collected and 

 studied for their parasites, and out of 99 observed, 48 yielded parasites, 

 and three species of Chrysopa were bred, \nz : — C. riiflabris, Banks, 

 <7. nigricornis, Burm., and C. ocidata. Say, the majority being the first- 

 named. The parasites, in order of abundance, were : — Chrysophagus 

 compressicornis, Ashm., the Chalcids, Perilamjms sp. n., Goniocerns 

 sp. n., Isodromus iceryae. How., the Ichneumon, Orihizema atriceps, 

 Ashm., and Helorus sp. n. C. compressicornis, besides being frequently 

 reared from Chrysopids, on one occasion was reared from an un- 

 determined Syrphid pupa from which the Chalcids, Pachyneuron 

 allograptae, Ashm., and Syrphophagus mesograptae, Ashm., were also 

 obtained.
