Pest of dates

StiiliKjiwsdiiia cijnauvhc (fig. 3) was noticed in largo numbers at Shendi. It is dark 
Iji'own in colour with gold markings. Dorsum of the prothorax with a broad lateral stripe 
beginning on the bases of the elytra and extending on to the bead. Elytra each with three 
lateral patches and two median smaller marks. Pygidium with two gold-coloured areas. 
Length, 9-12 mm. 
Both species feed freely on the foliage of trees, and when present in any numbers are 
capable of doing a considerable amount of damage. A large green buprestid (fig. 7) 
sometimes attacks trees in a similar way. 
Preventions and remedies. — The beetles can usually be jarred or shaken from the trees, 
collected and destroyed. A poisonous spray applied to the foliage of the trees on which 
they are feeding would also probably prove effective.

This coceid occurs on date palms throughout the northern parts of the Sudan, and is 
very common in Khartoum. Many of the dates exposed in the streets for sale from the 
190G crop were smothered with this insect. 
It usually confines its attentions to the date palm, but recently it has been recorded by 
Draper' to attack yellow jasmine and periwinkle. 
It is found throughout Northern Africa, and has also been recorded from Australia. 
The male scale (fig. 2) is about 1 mm. in length and elongate in form. Colour, greyish- 
white; pellicle, yellowish-brown. 
The female scale (fig. 3) is about 1-5 mm. in length and ovoid in form. It is almost 
entirely covered by the second pellicle, there being only a narrow, semi-transparent, greyish- 
white secretionary border. Second pellicle, yellowish-brown with a dark brown centre. 
First pellicle, yellow to dark brown. 
Remedial treatment . — Spray the infested plants with kerosene emulsion.
