Speyer (E. R.). Borers on Tapped Surfaces of Rubber — Trop. Agricul- 

 turist, Peradeniija, 1, no. 4, April 1918, p. 205. [Received 

 ' 21st June 1918.] 



At a meeting of the Committee of Agricultural Experiments held 

 at Peradeniya in March, the author repoi-ted that in 55 per cent. 

 of the recorded cases of Scolytid borers attacking rubber trees, the 

 latter, or parts of them, had already been killed by fungi. There 

 were no recorded cases of successful attack in healthy trees or healthy 

 portions of trees. In recent reports of borers in tapped and untapped 

 surfaces treated with tar and liquid fuel, it is probable that they had 

 been attracted to small diseased patches and that in no case had the 

 beetles been able to pass the latex layers. The remedy is to be found 

 not in stopping the application of preservatives, but in removing 

 at an early date the dead wood in which the beetles originate, and 

 immediately destroying it by fire.

 Rur., Paris, viii, no. 24,'l5th June 1918, pp. 407-409. 



This paper is a resume of previously pubhshed results 6i the 

 experimental use of alcoholic liquid bait traps for vine moths. 

 Against Sparganothis pilleriana and the summer generations of Clysia 

 ambiguella and Polyclirosis hnUrnia these traps afford a simple, cheap 

 and eftie«t;iou^ means of control, most useful in hot, dry seasons. 

 They can never constitute a means of extinction, since their 

 action is so limited against the spring generation, which it is 

 most important to destroy ; they form however a valuable secondary 

 means of checking t\Nalight-flying moths that are not affected by 

 light traps.

 Seychelles, for 1917.— MS. from Colonial Office, received 24th 

 June 1918. 



'The following list is giveii. of the insects attacking coconut in 

 Seychelles : Oryctes rhinoceros (rhinoceros beetle) ; Melitomma 

 insulare ; Diocalandra frumenti ; Eugnoristus braueri ; Ischtmspis 

 longiroslris {filijormis) ; Chrysomphalus aonidum {Aspidiotus ficus), 

 Chrysomphahis {Aspidiotus) dictyospermi ; Aspidiotus lataniae ; Aspi- 

 diotus ansei ; Chionaspis inday ; C. dilatata ; Icerya seychellarum ; 

 Vinsonia stellifera ; Eucalymmttus (Lecanium) tessellatus. Oryctes 

 rhinoceros is doing damage owing to the refuse from the essential-oil 

 distilleries forming new breeding places. The discovery in Madagascar 

 by Mr. d'Emmerez de Charmoy of natural parasites of this beetle 

 gives an opportunity for combating it by their introduction into 

 Seychelles. These parasites are Scoliid wasps of which three species 

 {Triscolia hyalinata, Dielis collaris var. coelebs and Scolia pilosella) 

 already occur in Aldabra, a Seychelles 'dependency, N.W. of 

 Madagascar. TJiis means that the rhinoceros beetle parasite {Scolia 

 oryctophaga) and other Scoliidae would in all probability be easily 

 acclimatised in Seychelles. Melitomma insulare is even worse than
