Locusts. — Agric. News, Barbados, xiv, no. 343, 19th. June 1915, p. 203. 



The fears that locusts might invade Trinidad from Venezuela [see 

 this Review, Ser. A, iii, p. 618] appear to have been justified, since 

 specimens of Schistocerca paranensis, the South American migratory- 

 locust, have been taken at Chacachacare, Trinidad, large swarms 

 arriving there on 30th May. A related form, S. palle^is, is the common 

 grasshopper in the West Indian Islands, whilst S. americana is the 

 abundant, and sometimes seriously injurious locust of the southern 

 United States. Spraying with lead arsenate or sodium arsenate and 

 the use of a poisoned-bran bait are effective against the adults and will 

 prevent the laying of eggs in large quantities ; the eggs should be 

 destroyed by ploughing or digging the ground. 



Cleaee (L. D.). Note on the recent Attack of Brassolis sojjhorae. — 

 Jl. Bd. Agric. Brit. Guiana, George'own, viii, no. 3, Julv 1915, 

 pp. 86-87. 



Coconut palms in Georgetown suffered from an attack of Brassolis 

 sophorae during the past year. This pest has been previously recorded 

 from the East coast at Berbice and Essequibo and is probably to be 

 found along the entire coastlands. It has been recorded from Dutch 

 Guiana and Trinidad. The spread of the insects in Georgetown was 

 in opposition to the prevailing winds. By September, the insects had 

 almost disappeared. About 5 per cent, of the palms were killed by 

 the attack. The natural enemies of B. sophorae include a bird, Pitangus 

 sulphur atus, and parasites of eggs and pupae. The habit of the larvae 

 of feeding by night and living in nests in the daytime offers the easiest 

 means of control, viz., the collection of leaves bearing the nests.
