propos du Ver du Cotonnier. — Bull. Union Agric. Egypte, Cairo, 

 xix, no. 142, November-December 1921, pp. 129-132. 

 A meeting of the Ministry of Agriculture was held on 20th December 

 to consider the adoption of a supplementary decree suggested by the 

 Union of Agriculturists of Egypt in view of the continued depredations 

 caused by the pink bollworm [Platyedra gossypiella]. The effect of 

 the decree is to enforce the compulsory destruction of fallen capsules 

 and the collection and burning of bolls stiU on the plants, as well as 

 the fallen ones. It is also suggested that better results might be 

 obtained if a small sum were paid for collected bolls as has been done 

 for collected locust eggs. It was reported that in spite of the systematic 

 collection of capsules and the application of other remedial measures 

 that have been carried out in a certain district for the past four years 

 there appears to be no evident reduction of the moth. It would, 

 therefore, seem that some other method of control will have to be con- 

 sidered. It is possible that the growing of an early variety of cotton, 

 at least for a few years, might have the effect of reducing the damage 

 caused.
