The moth-borer, Diatraea saccharalis, ¥., is the chief insect pest of 

 sugar-cane in Guadeloupe. In one locality the fohage of young 

 seedling cane was much injured by an Aphid, Sipha flava, Forbes. 



The following cane weevils appear to exist in the island : Diaprepes 

 abbreviatus L. ; D. abbreviatus var. marginatiis, Oliv. ; D. abbreviatus 

 var. distinguendus , Gyl. ; a form of D. abbreviatus, intermediate 

 between var. marginatus and var. distinguendus ; and D. famelicus, 

 Oliv.

Haltica ampelophaga has injured vines in some areas. In Malaga 

 wheat was attacked by Thrips cerealium, Cephiis pygmaeus, and 

 AnisopUa segetwn.

Numerous vineyard tests have shown the efficiency of nicotine or 

 pyrethrum-soap sprays against the vine moth, Clysia ambiguella, Hb 



Nicotine, added to a copper spray, gives the best result if the applica- 

 tion is made at a time when the largest number of eggs can be reached. 

 This implies some biological knowledge and great watchfulness. 

 Pyrethrum-soap solution is applied when the caterpillars are 2-5 mm. 

 long, and it is thus easier to choose the most favourable date for using 

 this insecticide. Most excellent results were obtained with it in 1920, 

 and pyrethrum is now being largely grown. The viticultural station 

 at Lausanne distributes seed and seedlings ; requests for them have 

 also been received from abroad.

 xiii, no. 24, 11th June 1921, pp. 267-269, 1 fig. 



The very dry winter of 1920-1921 favoured the development of 

 many insect larvae, including those of Tipula oleracea, which ha\'e 

 caused serious loss in many gardens. 



The remedies advocated are the use of kainit, rolling with a heavy 

 roller, or fumigation with carbon bisulphide poured into holes 6 in. 

 deep, though where plants are already growing, the latter method is 

 the only one available.

The work in connection with insects as transmitters of mosaic 

 disease of sugar-cane has been continued [R. A.E., A, viii, 483]. The 

 inauguration of a special plant quarantine service is discussed, and the 

 recent regulations issued against cotton from Porto Rico owing to the 

 occurrence of Eriophyes gossvpii (cotton-leaf blister mite) are recorded 

 [op.cit./\x,3\3].
