 Brief notes on the life history, habits, and means of combating imported ehn-leaf

The importance of parasitic insects in agriculture, A. Berlese (7)u/. I\. 

 Srnola Superiore A</r. Portici, 2. ser., 1902, No. 4, pp. 27, fiys. iw^).— Descriptive, bio- 

 logical, and economic notes are given on the common species of parasites which infest 

 scale insects, lepidopterons caterpillars, and other insects. A brief account is given 

 of i)redaceous and i)arasitic insects, and also on artificial insecticide treatments. 



The present status of the Mexican cotton-boll weevil in the United States, 

 W. I). Hunter {l\ S. Dept. Ayr. Yearbook 1901, pp. 369-380, fi(j. 7).— This insect was 

 descriljed in 1843, but iirst accjuired importance as an injurious inse(!t in the United 

 States in 1894. Its disti'ibution isat present confined to the State of Texas, where it 

 occupies more than half of the cotton belt of that State. The State (jf Texas has 

 api)ropriated considerable funds for making a study of suitable means of cond)ating 

 the weevil, and recently special i)rovision has b'een made by C!ongress for this i)ur- 

 pose. The insect is not killed l)y freezing in winter, and while several parasites of 

 an insect and fungus nature are known to attack it, they are of little practical im- 

 portance. The writer believes that the insect will migrate northward and will soon 

 be outside the boundaries of Texas. The remedies most strongly recommended are 

 cultural methods, the chief of which is early planting, the total destruction of plants 

 in the field as soon as the gathering of the late crop becomes doubtful, and grazing 

 of such green plants by cattle. Some importance should be attached to planting the 

 rows as far apart as the soil will permit. Special machines have been devised for 

 spraying the cotton plant, for jarring the insects or infected squares from the plants, 

 and for picking up fallen scpiares from the ground. 



Spraying tests for codling moth — New Zealand experience {Jour. Agr. and 

 Ind. South Australia, 5 {1902), No. 2, p. 904) ■ — Notes are given on the results obtained 

 from spraying experiments by W. A. Boucher. The experiments included tlie use 

 of Paris green in limewater; the same mixture with the addition of resin wash; a 

 mixture containing white arsenic, washing soda, and limewater; and arsenate of 

 lead. The last insecticide burned the foliage quite severely. Excellent results were 

 obtained from the use of Paris green, 90 percent of the fruit jn-oving to besoumland 

 uninfested with the codling moth. 



Spraying orchards for the codling moth, F. Garcia {Neiv Mexico Sta. Bui. 41, 

 pp. 20, pis. 3) . — The codling moth is becoming a serious pest in New Mexico. It 

 was introduced into the Territory about 10 years ago and is now quite abundant in 

 infested localities. Notes are given on the habits and life history of this insect and 

 formulas are presented for preparing the usual arsenical sprays for application in 

 destroying the codling moth. Experiments were made in sjiraying 5 varieties of 

 winter apples. The trees were sprayed at intervals of 2, 3, and 4 weeks and some of 

 the trees were banded and examined at intervals of 2 weeks, while the other trees 

 were left without bands. The results of the authors' observations and experiments 

 indicate that from 65 to 95 per cent of the ajiples on unsprayed winter trees are 

 usually destroyed by the codling moth. A considerable number of worms were 

 found under the bands in most cases and this remedy, therefore, appeared to be of 

 some value. As a rule, the more frequent the spraying, the more effective was this 

 treatment. It is believed that spraying in New Mexico will reduce the percentage 

 of wormy apples very materially. Two early sprayings are not considered sufficient. 

 Arsenite of soda is considered more satisfactory than Paris green. Early ajiples are 

 quite free from worms while the second brood of codling moths is more injurious 

 and destroys a larger percentage of late apples.
