Shepherd (F. R.). Notes on the Destruction of Cotton Bushes by 

 Burning. — Agric. Jl. India, Calcutta, xii, pt. 1, January 1917, 

 pp. 120-121. 



The general custom in India has been to destroy by burning cotton 

 plants which are heavily infested by the leaf-blister mite {Eriojphyes 

 gossypii] and black scale [Saissetia nigra ?], when successive crops 

 are to be grown on the same land. The experiment of burying them 

 in as green manure has been tried with excellent results ; the new 

 crops have not been infested with the mite when the old plants have 

 been pulled up instead of being cut down, provided that this is done 

 6 or S weeks before planting the new cotton.

The Chalcidid, Aphycus hesperidum, sp. n., which is described in 



this paper, has been found parasitising Chrysomphalus dictyospermi 



on orange trees^ laurels and oleanders in Spain [see this Revieiv, Ser. 



A, V, p. 248]. Other natural enemies of C. dictyospermi recorded are 



Ajjhelinus cJirysomphali, ProspaJtella lounsburyi, and the Coccinellid, 



Ckilocorus hipustulatus.

None of the birds in the vineyards of lower Provence are really 

 harmful to the grapes, while a great many feed upon insects and for 

 that reason should be protected. The beneficial species include 

 Cucidus canorus and Parus major, which are especially useful as theV 

 destroy the woolly caterpillars of Arctia caja, L., and the night-jar, 

 Caprimulgns europaeus, which destroys many moths.

This paper records the author's observations on Ceratitis capitata 

 in an experimental garden in Tunis. Larvae were abundant in July 

 and August on peaches, apricots and persimmon, and in August, 

 September and October on pears and apples. In December and 

 January oranges were attacked. Experiments with fruits attached 

 to the trees and smeared with honey to act as traps vv^ere unsuccessful, 

 as also were traps containing a solution of colophony in alcohol and 

 castor oil. On gro\\'ing fruit the larvae collect in the mesocarp near 

 ^he stone, and in oranges in the spaces round the seeds. Recorded
