278 EXPERIMENT STATION RECORD. 



thai in Cyprus cereals thrashed and placed in a clean storeroom early in the season 



are nol attacked by granary inserts. Soi >f the fanners in Cyprus scatter bulbs of 



squill over the piles of grain in order to prevent the attack of these insects. A num- 

 ber of other j >l;ints such as species of Origanum, Inula viscosa, etc., are occasionally 

 used for the same purpose. 



The processionary moth of the pine tree, I*. Gennadius (Cyprus Jour., I 

 (1904), No. '/./'/>.!>. W). — Onethocampa pityocampa is common along the Mediter- 

 ranean and occurs in such numbers as to strip whole groves of pine trees of their 

 foliage. The habits and life history of this species are briefly described. The cater- 

 pillars are furnished with nettling hairs. In combating the pest the author recom- 

 mends that branches bearing nests of the caterpillars be cut off and burned. 



The Congo floor maggot, J. E. Dutton, J. L. Todd, and < '. < Jhristy | British Med. 

 Jour., 1904, No. '.'SI, pp. 664-666, figs. ..'). — A description is given of door maggots 

 as found in the Lower Congo region. These pests are reported as attacking man for 

 the purpose of obtaining blood. Experiments with maggots show that they could 

 live also on rats and guinea pigs. Further experiments will be made to determine 

 whether these larva' are capable of transmitting any form of trypanosomiasis. The 

 larva:- were identified as belonging to the species Auchmeromyia luteola. 



What Government experts are doing to destroy the boll weevil, C. A. Wil- 

 liams ( World To-day, 7 (1904), No. 4, pp. 1307-1313, figs. 11).— The author briefly 

 discusses the economic importance of cotton and the great injury which this industry 

 has suffered from the ravages of the boll weevil. Attention is called to the work 

 outlined by this Department for the control of the boll weevil and brief hints are 

 given as to future work along this line. 



The boll weevil in Texas ( U. S. Dept. Com. and Labor, Bureau of the Census Bui. 

 10, pp. 15-17, fig. 1). — The history of this pest is briefly outlined with notes on its 

 present distribution in Texas and the amount of damage caused by it. 



Tortrix pilleriana and Haltica ampelophaga, J. Perraud (Rev. Agr., 17/. et 

 Hort., 1 (1903), No*. 1, pp. 7-10; 2, pp. ,15-35; 5, pp. 103-110; 8, pp. 169-172; 11, pp. 

 254-257; 12, pp. 265-270; 2 (1904), Nos. 14, pp. 36, 37; 15, pp. 52-54).— The habits 

 and life history of these insect pests of the grape vine are discussed in great detail 

 and the various methods used for their destruction are described. 



These methods consist in spraying with a large variety of insecticides, boiling 

 water, sulphur fumes, etc. The eggs may be readily found and destroyed and vari- 

 ous contact insecticides are useful in the destruction of the larva. For this purpose 

 particular mention is made of tobacco juice, black soap, kerosene emulsion, and 

 other similar insecticides. The moths may be trapped by lanterns and the use of 

 sugar. 



A number of insects prey upon both T. pilleriana and If. ampelophaga, and these 

 species are briefly described by the author with notes on their distribution and rela- 

 tive importance. One of the most successful insecticide operations in connection 

 with the caterpillars of T. pilleriana is the use of boiling water as a spray during the 

 winter season. 



The prey of Methoca ichneumonides, G. Adlerz (Ark. Zool., 1 (1904), No- S, 

 pp. 255-258). — This species belongs to the family Mutillidse and its habits were 

 studied in the central part of Sweden. The author found that this species could 

 attack and destroy the larvae of tiger beetles. 



Combating the olive fly, Trabut (Bui. Agr. Algerie et Tunisie, 10 (1904), No. 10, 

 p. 227). — The olive fly was observed to be easily attracted by sweetened fluids. A 

 successful attempt was therefore made to destroy these insects by preparing a mixture 

 of molasses, honey, glycerin, water, and arsenate of soda. 



Anobium paniceum in wheat, A. Legault (Bui. Agr. Algerie et Tunisie, 10 i 1904) , 

 No. 11, p. 233, fig. 1). — Brief notes are given on the appearance and habits of this
