Smulyan (M. T.)- U.S. Bur. Eiitom. Key and Descriptions for the 

 Separation and Determination of the first Instar Stem Mothers of 

 the Three Species of Aphids most commonly attacking the culti- 

 vated Apple. — Psyche, Boston, Mass., xxv, no. 2, April 1918, 

 pp. 19-23. 



A detailed description is given and a key for the identification of 

 the first-instar stem-mothers of the following Aphids : — Aphis mali- 

 foliue, Fitch. {A. sorbi, Kalt., of recent American authors) commonly 

 known as the rosy apple aphis ; A. pomi, Deg., known as the green 

 apple aphis ; and A. prunifoliae, Fitch {A. avenae, ¥., of recent American 

 authors), knowTi as the apple-grain aphis. A. frunifoliae is the 

 first of the three to begin hatching, and in Virginia may begin as 

 early as the middle of March. The other two species begin about 

 10 days to 2 weeks later.

In the course of this paper, the author remarks that among the 

 many host-plants of Agromyza pusUla (common leaf-miner), he has 

 reared it from mines in leaves of the common milkweed, Asclepias 

 syriaca, and has found what is apparently the same larva in leaves 

 of the horsemint, Monarda pit aetata. In the milkAveed, the miner 

 feeds in the palisade tissue and does not touch the laticiferous system 

 lower down in the leaf.

In the course of this paper it is pointed out that about 95 per cent, 

 of insect pests spend their "sv-inter in the ground in one stage or another. 

 Piles of rubbish, clumps of grass and clods of dirt also shelter numerous 

 beetles and other insects. If all farmers would break up their soil 

 to a depth of 6 inches or more in early autumn or winter, they would 

 destroy insect pests more quickly than any spraying machines can. 

 Since the aimual damage to agriculture by insects alone in Texas is 

 estimated to be more than £10,000,000, the advantages of this method 

 of destroying them are obvious.

 Institute, 1917, pp. 69-70 & pp. 100-101. [Received 15th May

An account is given of the pink bollworm of cotton [Pectinophora 

 gossypiella] and attention is called to the danger of this pest appearing 

 in the cotton belt of the United States.
