on the plants. Hand-picking is beneficial. Where P. ornithogalli 

 occurs alone, hand-picking in the late afternoon is recommended, or a 

 poisoned bran mash may be used consisting of 5 lb. bran and \ lb. 

 Paris green mixed together and moistened with f U.S. gal. water into 

 which has been mixed lemon juice and 1 U.S. pt. cheap molasses. A 

 small quantity of this bait should be placed among the infested plants 

 in the late afternoon. 



The cyclamen mite [Tarsonemus paUidus] is a comparatively new 

 pest, but a serious one, as it dwarfs the injured parts of the plants. 

 Nicotine oleate and tobacco dust have given fair results. 



Owing to the spread of Pyrausta nubilalis (European corn borer) 

 Indiana had been listed as a State to be quarantined against the 

 importation of maize, grain or vegetables likely to carry this moth, 

 but this was eventually cancelled by the Federal Horticultural Board. 

 In the year under report Heliothis ohsoleta (corn ear worm) was a 

 far more serious pest to maize and other crops owing to the fact that 

 the warm period earl}- in the spring caused the adults to emerge sooner, 

 so that the first generation was four or five weeks ahead of the growing 

 season for maize. The second generation developed a little later 

 than the first brood does in normal seasons and in far greater numbers. 

 Instead of hibernating as pupae, the moths emerged, and a full third 

 brood came in time to work on the field maize and late sweet maize. 



Against ants in houses a poisoned syrup, made by boiling together 

 10 pts. sugar to 100 pts. water, adding 1 pt. tartar emetic is effective. 

 A small quantity of this should be placed in shallow dishes containing 

 a sponge.

During 1920 and 1921, a systematic and biological study was made 

 of the Coccids of Mississippi, and also of the insects affecting pecans, of 

 which there are about fifty, especial attention having been given to 

 the hickory bark-beetle [Scolytus quadrispinosus], while the importance 

 of Lachnosterna (May beetles) as pecan pests has been the subject 

 of a fresh investigation. Twenty-five species of Lachnosterna have 

 been found, twenty of which were taken feeding on pecan trees. 

 Laphygma fyitgiperda (Southern grass worm), and its parasites have 

 been reported upon elsewhere [R.A.E., A, x, 1941. A survey of 

 infestation by the cotton boll weevil [Anthonomiis grandis] showed 

 about 30 per cent, of parasitism in some localities, while in others 

 no parasites were found. Many species of parasites were obtained, 

 the majority of which have not yet been identified.

 [Received 11th April 1922.] 



The Orthoptera occurring in Tennessee are described, and keys 

 are given to the genera and species. The habits are discussed and 

 remedial measures are suggested for the species that may prove to be 

 injurious. An extensive bibliography and a glossary of the terms 

 used in the text are included.
