Egg-plants and okra were attacked by Pseiidococcus virgafus, 

 Pulvinaria urhicola, Saissetia hemisphaerica , S. oleae, Diaspis pentagona 

 and Aphids. A few specimens of Diaprepes abbreviatus were found on 

 okra pods. 



Tomatos were attacked by Heliothis {Chloridea) ohsoleta (tomato 

 fruit worm), D. pentagona, Pulvinaria nrbicola, Pseiidococcus virgatus, 

 Dysdercus andreae, Aphids and Nezara viridiila, which caused most 

 damage by puncturing the blossom ends. Hand-picking is recom- 

 mended as a control measure. 



Stored grain and grain products were severely damaged by Calandra 

 granaria, C. oryzae (grain weevils), Pyralis farinalis (meal snout moth) 

 and Plodia interpunctella (Indian meal moth). The control measure 

 used against these insects was fumigation with 1 lb. carbon bisulphide 

 to 1,000 cu. ft. of space.

Further cases of Trogoderma khapra, Arrow, infesting breweries in 

 England are recorded, [cf. R.A.E., A, ix, 143.] It was found in 

 bran from the west of England associated with Aleurobius farinae 

 and Glyciphagus cadaveruni. 



Monomorium pharaonis is recorded as destructive to sweetmeats in 

 London. 



Farm and garden pests mentioned are : Ceuthorrhynchus sidcicollis, 

 Gyll., on cabbages ; Trombidiiim holosericeum found in the vicinity 

 of beans ; Melolontha meloloniha {vulgaris) ; Collembola ; Phyllobius 

 oblongus on apples and shrubs ; Pineas [ ? Pissodes] pini, L., on conifer 

 seedlings ; Aphis pruni on plum trees ; Otiorrhynchus sulcatus on 

 flowering plants and vegetables ; and Aleurodes brassicae on tomatos, 

 cabbages and greenhouse plants.

 Qtrly. Jl. Forestry, London, xv, no. 3, July 1921, pp. 157-159. 



Chermes cooleyi. Gill., was probably introduced into England from 

 North America. It occurs on Douglas fir, but its economic importance 

 cannot be accurately estimated until more is known of its life-history 

 in this country [cf. R.A.E., A, iv, 523; viii, 423]. In nurseries it 

 may be controlled by nicotine soap wash or even strong soap wash 

 alone, applied in the autumn.

 pp. 213-214. 



Myzaphis abietina, Wlk., is recorded from Dorset on Sitka spruce. 

 The trees were apparently growing on unsuitable soil. Contact 

 insecticides are advocated for Its destruction in nurseries [cf. R.A.E., 

 A, ii, 619]. The long-eared bat is predaceous on this aphid. It is 

 noticed that in France the encouragement of bats is advocated as a 

 protective measure against pine shoot tortrices [R.A.E., A, vii, 17].
