the larvae of the PyraUds, Diaphania hyalinata, L., and D. (Glyphodes) 

 nitidalis, Cram. A lead arsenate spray will satisfactorily control 

 the former. Sweet potatoes were infested by the bug, Spartocera 

 batatas, F., the larva of the Pyrahd, Terastia pusialis, Snell., a 

 Eumolpid beetle, Typophorus nigritus, and the sweet potato weevil, 

 Euscepes (CryptorrhyncJius) batatae, Waterh. Considerable damage 

 was done to tannias and eddoes by the larva of a hard-back (probably 

 Oxyligyrus zoilus, Oliv.). Diatraea saccharalis, F., is fairly common 

 in some districts on maize, and in others the larva of Laphygma 

 friigiperda, S. & A., completely destroys young plants by eating 

 out the central shoot. It may be effectively controlled by introducing 

 a small quantity of lead arsenate into the heart of the plant. Egg- 

 plants were attacked by Epitrix pilosa, Jac, which may be controlled 

 by dusting with lead arsenate ; the Coccids, Saissetia hemisphaerica, 

 Targ., and Pseudococcus virgatus, Ckll. ; and an Aleurodid, Aleurodicus 

 sp. On peppers the larvae of L. frugiperda and of Protoparce sexta 

 paphus, Cram., have been observed. Cassava was attacked by a 

 Pyralid borer and the larva of Erinnyis ello, L. 



No serious pest of bananas and plantains was noted, but the larvae 

 of Castnia licus, Westw., the Syntomid moth, Antichloria eripJiia, 

 ¥., and Caligo illioneus illioneus, Cram., were occasionally found. 



Guava fruits were frequently infested by the guava fruit fly, Ana- 

 strepha striata, Schin., and at times by the guava fire-tail moth, 

 Pyrrhopyge amyclas. Cram., as well as the Coccid, Pulvinaria 

 pyriformis, Ckll., which was very troublesome at times. 



Mango trees are often severely infested by the Coccid, Coccus 

 (Lecanium) mangiferae, Green. It covers the leaves with a sticky 

 secretion and they are then attacked by a sooty fungus. The mango 

 hairy worm is also prevalent, as well as the Coccid, Aukicaspisrosae, Bch. 



The pests of soursop {Anona muricata) include the larva of the 

 moth, Claphe lasconia, Druce, a species of Aphid, the larva of the 

 Limacodid, Sibine fusca, Stoll, and a large Aleurodid, Aleurodicus 

 giganteus, Q. & B. 



The Coccid, Orthezia insignis, Dougl., is sometimes most destructive 

 to roses and bougainvillea. A thorough pruning followed by several 

 applications of kerosene emulsion is recommended as the most effective 

 control measure. 



Stored products such as rice, corn, cashew nuts, biscuits, etc., are 

 liable to become infested with the grain weevil {Calandra oryzae, L.), 

 the larva of the Angoumois grain moth {Sitotroga cereallella, Oliv.) 

 and the confused flour beetle {Tribolium confiisum, Duv.). These 

 may be controlled by fumigation with carbon bisulphide. Considerable 

 loss in cigars and cigarettes is caused by the cigar beetle, Lasio- 

 derma serricorne, F. Fumigation will effectively control this pest, 

 which also causes considerable damage to books on open shelves. 

 These should be kept in well constructed cases, regularly fumigated, 

 and a quantity of napthahne kept on the shelves. 



Tables, cupboards, etc., should be rendered ant-proof by standing 

 them in large bowls filled with kerosene and water. The ants that 

 commonly occur are the red household ant {Solenopsis corticalis. 

 For., subsp. amazonicus. For.), the small crazy ant {Tapinoma 

 melanocephalum, F.) and the black crazy ant [Prenolepis longicornis, 

 Mayr).
