The Pimento Scale Insect. Jl. Jamaica Agric. Soc.„ Kingston, xxi, 



no. 2, February 1917, pp. 58-59. 



This recently described scale, Odonaspis piment<ie,'Newst., causes the 

 bark of pimento trees to become discoloured and to be ultimately shed in 

 small irregular pieces instead of in long strips. The scales also suck 

 the juices of the trees, so weakening them that they commence to die. 

 In some cases it interferes with the shedding of the bark, badly infested 

 trees being apparently unable to shed their bark at all, with the result 

 that they become stunted and die.

A description is given of a portable frame for fumigating a compar- 

 atively large number of small mango trees in the field. Working 

 directions are given and illustrated. In order to preserve the wood- 

 work from decay and from the attacks of termites, it is thoroughly 

 painted with carbolineum.

This report, which contains no scientific names, records a serious 

 plague of swarming caterpillars on rice in the seed-beds, which spread 

 to the transplanted crop. The plague was checked by sweeping up 

 the caterpillars and by dragging a fishing net over the crop, as well as 

 by destroying the pupae by scraping up the earth on the ridges round 

 the rice-fields and throwng it into the water. In September a second 

 brood appeared, which was spread over a larger area, but was less 

 numerous than the first and was controlled by hand-picking, by 

 disturbing the insects by means of a rope dragged over the crop and 

 by shaking them into water on which a little kerosene oil had been 

 poured. 



The rice bug {Leptocorisa) damaged some crops in September and 

 October so badly that a great deal of the rice had to be cut down and 

 used for fodder. 



In the Annual Report of the Jorhat Agricultural Experiment 

 station for the year ending 30th June 1916, the cane moth borer was 

 leported as doing considerable damage to sugar-cane at Jorhat.
