The pupal stage lasts for ten days to a month, the moths emerging 

 from February to October (May to September in Japan). The adult 

 is capable of a five-mile flight, and there are six generations a year 

 in tropical countries. Its natural enemies are Ommatius fulvidus, 

 AVied., and other Asilids, the wasps, Icaria sp. and Polistes hebraeus, 

 F., and the dragon-flies, Pantala JIavescens, F., Rhyothemis splendens, 

 Ramb., Asisoma panorpoides, Eamb., Trithemis trivialis, Ramb., 

 Lepthemis sabina, Drury, Ortketrum albistijla, Selys, and Agrion spp., 

 besides bats, spiders and frogs, and a bird, Buchanga atra. 



As regards methods of control, the treatment of rice stubble by 

 burning in a dry field, by ploughing in, in a moist field, or by submerging 

 in a field that can be flooded, is undoubtedly the best, especially when 

 put into practice over areas of at least five miles, and under strict 

 supervision. If this cannot be done, the collection of the egg-masses 

 before the shooting of the paddy is a useful measure.

Grease-banding of Fruit Trees. — Jl. Bd. Agric, London, xxiv, no. 7, 

 October 1917, pp. 750-752. 



All standard apple, pear, plum and cherry trees, or any stakes 

 used to support them, as well as any forest trees in the neighbourhood 

 of an orchard, .should be banded with some adhesive preparation to 

 catch the females of the ^\^nter moth [Cheiniatobia brumata,], which 

 would otherwise crawl up the trunks and lay their eggs on the stems 

 and branches. The bands should be fixed three feet from the ground ; 

 the preparation should not contain a pungent oil or cart grease ; and 

 only the ujjper two-thirds of the band should be covered. The work 

 should be done during September or before the middle of October, 

 at latest. 



An Experiment in Storing Seed-corn in Grenada. — Agric. News, 

 Barbados, xvi, no. 401, 8th September 1917, pp. 276-277. 



This paper is an account of experimental work conducted in Grenada 

 by the Superintendent of Agriculture, Mr. J. C. Moore. In storing 

 maize for seed it is necessary to remove as much moisture as possible, 

 without destroying its vitality ; consequently a high temperature 

 cannot be employed, as in the case of storing maize for food. The 

 cobs tied together in pairs were first hung across racks in a well- 

 ventilated wooden room with a shingled roof, the windows and venti- 

 lators being screened with h inch wire netting, but kept fully open 

 except at night and during actual rainfall. A few weevils were 

 noticed after hanging, but the only fumigation effected at this stage
