phaeorrJioea {Liparis chrysorrhoea) (brown-tail moth) present on fruit 

 trees in the environs of Paris. The winter collection of nests is advo- 

 cated as the best means of dealing with this pest.

Pink Boll Worm and Cotton Stem Weevil and their Attacks upon 

 Cambodia Cotton. — Trop. Agriculturist, Peradeniga, liii, no. 3, 

 September 1919, pp. 197-199' 



The rise in the price of cotton during the War has induced growers 

 of Cambodia cotton to leave their crop in the ground for two or even 

 three years instead of practising the usual rotation of crops. The 

 result has been that the pink bollworm, Pectinophora gossypiella, 

 has increased enormously, in some fields over 80 per cent, of the 

 cotton bolls being attacked. As the maximum length of the life-cycle 

 is 34 days, by clearing infested land of cotton for two or three months 

 the damage can be reduced to a minimum. 



Pemjjheres affinis (cotton stem weevil) is another dangerous menace 

 to the cotton industry of South India, 70 or even 100% of the cotton 

 in some fields being attacked. 



The only means of keeping these two pests in check is by clearing the 

 land of cotton for a definite period of the year and by pulHng up and 

 destroying their food-plants over wide areas. It is to enforce these 

 measures that the Madras Pest Act [R. A. E., A, vii, 360] has been 

 passed. 



A Useful Combined Spray.— .4(/fic. Gaz. N.S.W., Sydneg, xxx, no. 9, 

 2nd September 1919, p. 624. 



In experiments with various arsenates for the control of codUng moth 

 [Cydia pomonella] it has been found essential in hot dry seasons to add 

 some form of spreader to the mixture. Flour paste is unsatisfactory, 

 but soft-soap has given very good results, the lead arsenate being spread 

 out like a thick bloom on the fruit. 



The formula used was 8 lb. soft-soap, I pint tobacco extract, with 

 4 lb. lead arsenate, to 80 gals, water. Of fruit so sprayed only 4-8% 

 was affected by codling moth, and woolly aphis [Eriosoma lanigerum] 

 and scale-insects were killed by the same treatment.

Whenever lantana flies have been introduced into a new country with 

 a suitable cUmate they have spread with great rapidity over all open 

 land or areas that have been neglected and become over-run with weeds
