li the usual remedial measures employed against the caterpillars of 

 Heliothis, Phytomelra {Plusia), and 'Prodenia, infesting tobacco 

 [R.A.E., A, ix, 280] are to give the best results, it is necessary to remove 

 all possible breeding facilities after the crop has been harvested. The 

 upper, leaf-bearing portion of each plant should be cut off, so that it may 

 quickly wither on the ground and become unsuitable as food for the 

 caterpillars. Later on, when work is not so pressing on the plantation, 

 the plants must be uprooted and burned. The custom of placing 

 uprooted stems in heaps in the tobacco fields provides the pests with 

 a food supply, especially inside the heaps. Early burning not only 

 helps to keep the caterpillars down, but also removes a source of slime 

 disease, and furthermore, the material yields an ash with a higher 

 potash content.

An injury to coffee consisting in V-shaped indentations on the 

 twigs, which often caused them to break, appears to be due to a 

 Gryllid depositing its eggs in the twigs. The caterpillars of Parasa 

 lepida did some injury, but their collection and that of the cocoons 

 prevented their spread. A Flatid, Lawana Candida, occurred here 

 and there, but did little injury.

The chief coconut pests were Oryctes rhinoceros and Rhyncophorus 

 ferrugineus, which were very numerous in different parts of the 

 Peninsula. Field observations and detailed investigations were made, 

 and lectures on the habits of the beetles were given to the head men in 

 various districts. Minor coconut pests included skipper and nettle 

 caterpillars {Hidari irava and Thosea sp.). 



On rice, Spodoptera mauritia (army worm), appeared in August, 

 but was kept in check by hand-picking and by a Tachinid parasite.
