occasioned an immediate eradication campaign under the super- 
vision of Deputy Horticultural Commissioner G„ R« Horton," 
in charge of Insect Pest Quarantine in Los Angeles County,. As 
a result it has been necessary to arrange for the destruction 
of some 3,000 flowering peach trees of various species in these 
nuTBeries t Tfcis action was taken "by Mr, Gorton for the reason 
that this pest is not of common occurrence in Southern California 
and has never previously been reported in Los Angeles County. 
A check of the. previous distribution of all flowering peach 
trees from this nursery has been completed and necessary action 
taken to eliminate all possibility of infestation from this 
source, A detailed survey of all territory within a 2-mile 
radius of the infested nurseries has failed to show any other 
infestations,

From James Zetek, in charge of the field laboratory at Ancon, 
Canal Zone, it is learned that on February 1, T. H. C, Tavlor, 
Entomologist to the Department of Agriculture of Fiji, arrived 
in the Canal Zone on a journey from Trinidad, anr! -as a visitor 
at the field laboratory until his departure on F3bruary 3 for 
the Fiji Islands, He brought with him a large shipment of cages 
containing young coconut palms heavily infested ^ith the scale

Fiji, and Mr, Taylor believes that at least two of these ladybird 
beetles will prove very efficient in controlling it,

CITRUS 
SPIRAEA APHID ( Aphis spiraecola patch) 
Florida J% R* Watson (March 24): The citrus aphid ( Aphis spiraecola ) 
is less in evidence this spring than in any year since 1923, 
This is caused by the severe drought and freezes of the past

proportion of predators (ladybeetles and syrphus fly larvae) 
is three times as large as last year. They are having an 
appreciable effect in delaying the multiplication of the insect,
