468 Insect Pests. 



antennse dusky; cornicles green with black apices. Eyes black. 

 Wing buds all pale green. Slightly larger than the female. 



Winged viviparous femcde.—Hea.d and antennte deep green to 

 olive-brown ; the two basal segments of the antenna very deep brown, 

 base of the third pale grey. Eyes deep brown. Prothorax olive- 

 green, a pale green band before and behind ; thoracic lobes blackish, 

 rest of the thorax deep green. Abdomen, bright rich green above, 

 with an irregular median dusky line and broken dusky apical border 

 to the segments, green below and with three lateral dusky spots on 

 the sides, running up to the cornicles. Proboscis green at the base, 

 shiny black at the apex. Cornicles jet black. Legs fawn coloured, 

 femora and tibiie black apically; tarsi black. Wings with grey 

 stigma. The lice coming from the winter eggs are deep green. The 

 ovigerous female and male were, unfortunately, not noted. The eggs 

 are elongated oval, shiny black in colour. 



Natueal Enemies. 



E"o Ladybirds were noticed feeding on this aphis. This is where 

 some foreign Ladybirds might do good ; for it seems, judging from 

 what little has been done in this country in introducing them, that 

 they prefer to work low down, probably owing to getting greater 

 shelter, and amongst the dense growth of strawberry leaves they 

 would find all they want. 



Chalcid flies (Chalcididw), however, appear to do some good, for 

 on the 11th of June, numbers of aphis were sent me from Hereford 

 and some from Kent which had been attacked by these useful insects. 

 In one or two instances the strawberry leaves were covered with 

 brown dead aphides. 



Peeyention and Teeatjiext. 



The old leaves should be cut right back late in the winter, raked 

 together and burned. Very many eggs will then be destroyed. Some 

 are sure to escape, for they were found in the crowns of one plant 

 examined. 



Spraying is difficult if left until the trusses are coming out. The 

 dense growth of leaves protects many of the lice, and even a few 

 left may be sufiBcient to account for some thousands later. 



In 1905 the ova were hatching out in the latter part of March. 

 By the beginning of April would then be the time to give the plants 

 a heavy spraying with soft soap and quassia to kill the young lice
