 101. 



The Chrysomelid, Cassida inquinata, Brulle, is reported for the 

 first time in Anjou, where it attacks camomile cultivated for medicinal 

 purposes. It lives on the underside of the leaves, which it riddles 

 with holes. Unless the beetle is numerous the damage it does is not 

 great and the only remedy is to destroy the larvae and adults by hand.

 Egypt, Cairo, ix (1919), 1920, pp. 14-48. [Received 10th May 

 1920.] 



This paper is a consideration of the factors that have caused the 

 steady falling off in the yield of the Egyptian cotton crop during the 

 past twenty years. The influence of insect pests on this phenomenon 

 is discussed, the principal ones being the cotton worm {Prodenia litura)^ 

 the spiny bollworm {Earias insidana), the cotton stainer {Oxycarenus 

 hyalinipennis) and the pink bollworm {Platyedra (Gelechia) gossypiella). 

 P. gossypiella only affects the figures for the last five years, and though 

 P. litura and E. insidana cause great damage in certain years and 

 0. hyalinij^jennis is responsible for some loss, they were not less harmful 

 during the thirty or forty years from 1860 onwards, when there was 

 a steady increase in the yield. Insect pests do not therefore affect 

 the subject under consideration.

 Measure against Gelechia attacks. — Agric. Jl. Egypt, Cairo, ix

Tables are given showing the results of experiments carried out in 

 1918 to demonstrate the value of special watering of cotton to minimise 

 attack by Platyedra (Gelechia) gossypiella. As had been found before 

 [R.A.E., A, vi, 70], the reduction of the amount of Avater per watering 

 in July, and stopping of all water supply after, approximately, the 

 first week in August, increase the yield and make the crop ripen earlier.

Experiments in growing quince trees in Egypt are described. The 

 chief insect pest is the leopard moth [Zeuzera pyri^ia], the caterpillars 

 of which bore galleries in the shoots and branches. The trees should 

 be inspected weekly, and when any holes are noticed a wire should be 

 pushed in to kill the larvae inside. If the hole is too long or crooked 

 for this to be done, they may be killed by injecting carbon bisulphide 

 and stopping the hole with grafting wax immediately afterwards.
