Xyloterinus poliius. Say, prefers beech, but is also common in 

 maple and frequently birch. The larval cradles are described, with 

 the characteristics distinguishing them from those of Gnathotrichus, 

 Pterocylon and Trypodendron. 



The Black Citrus Fly and Jamaica Fruits in the United States.— ^grzc. 

 News. Barbados, xx, no. 495, 16th April 1921, p. 122. 



A meeting held in Washington, in December 1920, to discuss the 

 advisibility of prohibiting the importation of fruits or vegetables into 

 the United States from places where the citrus black fly, Alemocanthus 

 woglumi, Ashby, was known to occur, was attended by the Jamaica 

 Government entomologist, who argued that prohibition was un- 

 warranted in the case of the principal exports from Jamaica — bananas, 

 coconuts and citrus fruits. Bananas are not a food-plant of 

 A . woglimii, and the bunches are shipped without packing ; coconuts 

 are shipped husked ; and while Citrus is a food-plant of this pest, 

 the fruits are not attacked, and they are washed and packed separately 

 prior to shipment. Furthermore, Jamaica citrus fruits are shipped to 

 New York, which is far from any citrus-growing district. 



The Quarantine Order (no. 49) subsequently issued on account of 

 the citrus black fly, prohibited on and after 1st April 1921 the impor- 

 tation into the United States from Cuba, the Bahamas, Jamaica, 

 Canal Zone, Costa Rica, IncUa, Philippine Islands, Ceylon, and Java, 

 of fruits, vegetables, etc., except as provided for in regulations supple- 

 mental to the order. According to the provision of these regulations 

 " clean fruit and vegetables, other than those subject to special 

 quarantines, may be imported from the countries and localities named 

 in this quarantine, under permit, upon compliance with these regu- 

 lations." This would appear to make adequate provision for the 

 admission of fruits from Jamaica and other countries where citrus 

 black fly occurs. 



Ballou (H. a.). Trapping Cotton Stainers. — Agric. News, Barbados, 

 XX, no. 495, 16th April 1921, pp. 122-123. 



The methods usually employed for trapping cotton stainers [Dysdercus 

 spp.] are described. Trapping ought to commence before the stainers 

 have left the cotton fields for uncultivated land, and must be continued 

 even up to the time when the fields begin to supply them with food. 

 All cotton stainers left in the fields at the end of the season should be 

 trapped, as far as possible. In order to destroy the largest possible 

 number of stainers, therefore, the traps must be visited dail}^ and 

 the material forming them renewed from time to time. Stainers 

 appear to be attracted principally to suitable food in suitable situations, 

 shade and moisture, or coolness appearing to be very important. 

 The heaps of plants in the field at the end of the cotton crop will 

 attract large numbers of them, and a small quantity of cotton seed, 

 or cotton-seed meal on the ground under each heap would probably 

 enhance its attractiveness, by providing a large amount of food, 

 well protected and shaded. These heaps must be burned. For the 

 other type of trap, consisting of heaps of cotton seed or cotton-seed 

 meal, the kerosine or gasoline torch is best, because it destroys the 

 stainers without greatly injuring the bait. In the absence of a proper 

 torch a heap of trash burned on each trap will destroy many if not 

 all the stainers congregated there.
