Owing to the increased demand for castor oil and the lack of foreign 

 supply resulting from the war, several planters began cultivating 

 Ricinus communis minor in the Baku district. It was thought that 

 this plant would be very little affected by the existing pests. A tour 

 of inspection conducted in 1916, however, showed the crop to be 

 attacked by Heliotkis obsoleia {armigera), H: peltigera and Phycita 

 poteriella, Z. The various stages of the latter moth are described ; 

 it is apparently one of the most serious pests, as the larvae reduce 

 the crop by destroying the fruit. Wherever the castor oil plants 

 were grown in the vicinity of cotton plantations, the latter were 

 practically free from the attacks of H. obsoleta and H. peltigera, the 

 former apparently acting as trap-crops.

Various measures have been tried against the larvae of Prodenia 

 littira and other pests that occur in rice-fields in Goa. The best results 

 were given by a film of petroleum emulsion spread on the water. This 

 killed the larvae that fell when a bamboo was drawn along the tops 

 of the rice-stalks. Other means that have been, or will be, tried are 

 poison-baits, capture in a bag drawn along the infested plants, spraying 

 with lead arsenate, and deep ploughing with a view to exposing the 

 pupae to the sun and to natural enemies. As the larvae migrate 

 en masse, it is possible to check infestation by completely clearing a 

 belt from 15 to 24 feet in width across the line of march ; they starve 

 to death in crossing this bare area. A trench serves the same purpose.

 Agric. Circ, Fiji Dept. Agric, Suva, ii, no. 4, 'July-September 

 1921, pp. 84-85. 



The author has endeavoured to trace the history of Levuana iridescens, 

 B. B., in Fiji, and considers that it was probably introduced between 

 1860-77, when many native labourers were brought to the country 

 from the Solomons, New Hebrides and Rotuma.
