In Zanzibar, coconuts are attacked by Oryctes monoceros and, to 

 a lesser degree, by 0. boas. Larvae and adults of 0. monoceros have 

 also been taken on sugar-cane and in one case on sisal {Agave sisalina). 

 Nuts dipped in Cooper's dip before planting were found to be pro- 

 tected against termites. The outer husks of some nuts received 

 were smothered with a species of Aspidiotus, but the leaves were not 

 attacked. Clove trees in Pemba have been killed by Termes bellicosus 

 feeding on the bark of the lateral roots ; the dead branches were also 

 infested with Bostrychids. T. bellicosus is the worst timber pest 

 in the island, but does not usually attack Indian teak. Another 

 identified termite is Rhinoterm.es putorius, Sjost. The Bostrychid, 

 Dinoderus minutus, F., reduces all structures built of bamboo to dust 

 within a few years. Bamboo which has been soaked in water for a 

 few days is less liable to infestation. Split bamboos painted with 

 Cooper's dip (5 per cent.) gave good results, as all adults and larvae 

 were destroyed. All varieties of Egyptian and American cotton 

 grown experimentally were seriously attacked. The Lepidopterous 

 pests included Gelechia gossypiella, Saund., Earias insulana, Boisd., 

 Sylepta derogata, F., Prodenia litura, F., Orgyia vetusta, Hmp., and 

 Euproctis {Porthesia) producta, Walk. The favourite food-plant of
