Insects of the garden, R. H. Pettit (Michigan Sta. Bui. 233, pp. 77, figs. 65). — 

 The author has undertaken the publication of bulletins dealing with insects which 

 affect different classes of farm and garden crops, and this is the second bulletin of the 

 series. The insects considered in the bulletin are grouped under the plants affected. 

 All of the common garden crops are treated, with notes on their most important 

 insect enemies, the life histories of these pests, and means of combating them. Direc- 

 tions are also given for the preparation of various insecticides. The bulletin is pro- 

 vided with an index. 



Observations and short notes on the chief insect enemies of garden crops, 

 I. Vasilev ( Trudui Byuro Ent, [St. Petersb.], 6 (1905), Xo. 4, pp. 55, pis. 7, figs. 17) . — 

 The insects discussed in this report are classified according to their systematic posi- 

 tion. Biological and economic notes are given on Zeuzera pyrina, gypsy moth, brown- 

 tail moth, Hibernia defoliaria, codling moth, apple curculio, Epicometis hirla, fruit- 

 tree bark-beetle, apple-tree aphis, woolly aphis, oyster-shell bark-louse, etc. 



A monograph of insect injuries to Indian corn, II, S. A. Forbes (Rpt. State 

 Ent, III, 23 (1905), pp. XXXIII -\- 273, pis. 8, figs. 234).— The first part of the 

 author's monograph of corn insects (E. S. R., 8, p. 501) treated of insects injurious 

 to the planted seed and to the roots. 



The present part contains an account of insects which attack various parts of the 

 corn plant above ground. The author and his assistants have devoted much time 

 and energy to the study of all insects found on corn and particularly to the elabora- 

 tion of suitable remedies for these pests. In the present part of the monograph on 

 corn insects a large number of species are discussed and are classified for convenience 

 into the more important, less important, and unimportant species. The detailed 

 discussion of different species is preceded by an account of the adaptation and reac- 

 tion of corn to its insect visitors, general effect of insect injuries, peculiar features of 

 injury to different parts of the plant, and similar subjects. 



The insects discussed by the author are too numerous for individual mention in 

 this abstract. They include various species of cutworms, yellow bear caterpillars, 

 webworms, June beetles, flea beetles, oyster beetles, leaf hoppers, grasshoppers, as 

 well as ants, flies, spanworms, snout beetles, plant bugs, plant lice, red spiders, etc. 

 A particularly valuable part of the monograph from the standpoint of the practical 

 fanner is a key for the identification of all species concerned and based on the kind 

 of injury which the different insects cause. This key occupies pages 225-233 and 

 should enable the farmer to identify at once the insect pest with which he has to 

 deal. An elaborate bibliography of literature relating to corn insects is appended to 

 the report (pp. 234-273). 



Root maggots and how to control them, F. H. Chittenden (U. S. Dept. Agr., 

 Bur. Ent. Circ. 63, 2. ed., pp. 7 , figs. 5). — The seed-corn maggot (Pegomyia fusciceps) 

 attacks corn, beans, and many other vegetables. There are apparently several gen- 

 erations annually. 



Whatever insecticide treatments are chosen they should be applied before the eggs 

 are laid. A mixture of sand and kerosene may be placed at the base of plants for 

 the purpose of keeping the flies from depositing their eggs. The carbolic emulsion 

 may be used for the same purpose, made according to the formula calling for 1 lb. of 

 soap boiled in 1 gal. of water and \ gal. of crude carbolic acid diluted before use with 

 35 to 50 parts of water. Mineral fertilizers are of some value as deterrents, and good 

 results have also been obtained from the tedious method of hand picking. 



The cabbage maggot is most injurious in the northern tier of States and in Canada. 

 It may also be controlled by the use of carbolic acid emulsion, hand picking, fall 

 plowing, clean cultivation, the use of gas lime, carbon bisulphid, or tarred-paper 

 cards placed about the plants. The imported onion maggot (Pegomyia cepetorum) 

 attacks the bulbs of the onion, causing subsequent decay. The insect is briefly
