Locusta australis, Brunner, was numerous in a limited area, and 

 20 lb. bran, 1 lb. white arsenic, 2 qts. molasses, 3 lemons and 3| gals, 

 water proved an effective bait. Certain areas of grass-land, com and 

 oats were destroyed by Cirphis unipuncta, Haw. The outbreak of 

 a new grass pest, Oncopera mitocera, Turner, has already been noticed 

 [R.A.E., A, ix, 566]. Endeavours are being made to estabhsh the 

 known parasites of Phragmitiphila truncata, Wlk., at Ayr, where this 

 moth is causing serious damage.

 year ended 30th June 1921.]— J/. Dcpt. Agric. Union S. Africa, 

 Pretoria, iv, no. 1, January 1922, pp. 48-54, 1 table. 



During 1920-21, the most important scale-insects concerned in 

 quarantine in nurseries were : Chrysomphalus aurantii, C. didyospermi, 

 C. rossi, Diaspis pentagona, Aspidiotus perniciosus, and Eriococcus 

 araucariae. 



A small proportion of pear stocks from Europe was found infested 

 with living scale-insects. A small leaf -gall insect, thought to be 

 Procontarinia matteiana, has been twice found on mango. This 

 midge was recently introduced into Mauritius, where it has become 

 a serious pest. No changes were made in plant export regulations, 

 but permits were issued to admit quantities of ten pounds or less 

 of maize, barley, and cotton seed. Mangos imported in the previous 

 year were infested with a fruit-fly unknown in South Africa. A brief 

 account of locust work during the year is given, together with a table 

 showing the extent of the operations in the infested districts. 



Parasites of the woolly aphis [Eriosoma lanigerum] and codHng 

 moth [Cydia pomonella] have been introduced from America and 

 established in the country. Progress has been made in the taxo- 

 nomies and biology of South African terrriites, the bionomics, spread 

 and control of the tobacco slug [Lenia bilineata] and the control of 

 numerous other insect pests.

Pelargonium radnla is grown in the oasis of Tripoli for the essence 

 obtained from its leaves, which is used in perfumery. The insect 

 pests of it are mole-crickets [Gryllotalpa] and Melolonthid larvae. 

 Collection of the former and fumigation of the soil with carbon bisul- 

 phide against the latter are the measures advised.

The experience of ten years has shown that the Lotrionte system of 

 poison-traps for the olive fly [Dacus oleae] [R. A.E., A, ii, 289, 452, 479] 

 has preserved from three-quarters to four-fifths of the fruit from 

 attack, provided it has been applied in time.
