Earias hiegcU, Rog. (boll worm), and the Tineid, Pifi-cderces 'pijf- 

 rhodes, Meyr. (curved-winged cotton moth). A few Tachinid flies and 

 Graucalus melanops (black-faced cuckoo-shrike) exercise some control 

 on D. cinguhtus. The Proctotrupid, Telenomus danviniensis, Dodd, 

 heavily parasitises the eggs of T. lineola. The Chalcid, Bephratella 

 sarccphaga, Gir., is recorded here for the first time as a parasite of 

 E. huegeli, which is also parasitised by three other unidentified 

 Hymenoptera, 



Sisal hemp :■ — The Coccid, Hemichio)iaspis minor, Mask, (sisal hemp 

 scale) ; the Coccinellid, Orcus janfhinus, Muls., commonly found on 

 the foliage of Pandanus odoralissimus, preys on H. rnvwr, which is 

 also controlled by Anthemus sp. 



Pawpaw :— The Termite, Mastolermes danviniensis, Froggatt, and 

 the Coccid, Aspidiotus orientalis, Newst. (oriental scale). The latter 

 is slightly checked by several species of Coccinellids. 



Citrus trees i — The Coccids, ChrgsonipJmhis aumntii, Mask. (Aspi- 

 diotus coccineus, Genu.) (red scale of orange), C. aonidum, L. (Aspidiotus 

 ficus, Ashm.) (brown scale), Lepidosaphes beclii (Mytilasjns dtri- 

 coh, Pack.) (purple scale), Lepidosaphes (Mytilaspis) palUdus, Green 

 (pallid scale), Parlatoria ziziphus, Lucas (lime scale), and Icerya sp. 

 (cottony-cushion scale), and the Acridiid, Cyrtacanthacris tnuculi- 

 collis, Walk, (brown locust). An cntomogenous fungus (Microcera) is 

 probably the most effective check on the spread of C. aonidum. 



Mango :— The Noctuid, Bombotelia jocosafrix, Guer. (mango moth), 

 and the termite, Maslotermes danviniensis, Froggatt. 



Coconut palm :■ — The Acridiid, Cyrtacanthacris macidicollis ; the 

 termite, 31. danviniensis, Froggatt ; the Curculionid, Diocalandra 

 fnimenti, F. (Calandra stigmaticollis, Gyll.) (little coconut weevil) ; 

 the Coccids, Aspidiotus destructor, Sign, (transparent coconut scale), 

 and C. aonidum. 



Stored grain :— Calandra oryzac, L. (rice weevil). Two Chalcids 

 have been reared in large numbers from weevil-infested grain, which 

 have been determined by Mr. A. A. Girault as Spalangiomorpha 

 fasciatipennis, Gir., and Neocatolaccus austraJiensis, Gir. 



This paper also gives formulae for kerosene emulsion, oil of tar 

 emulsion, resin compound and tobacco and soap, with brief instructions 

 for making up these insecticides.

This paper deals with hydrocyanic acid gas, carbon bisulphide, 

 sulphur dioxide, carbon dioxide and nicotine, and their use as f umigants. 

 The properties of these substances and the methods of using them are 

 described. The pests of stored seeds and foodstuffs in Malaya include 

 Calandra oryzae, Sitotroga cerealella, Ephestia spp., Tribolium sp., 

 several species of Bruchid beetles and Lasioderma serricorne (cheroot 

 beetle).
