times introduced from the United States jjy Tillyard, with the help 

 of the United States Bureau of Entomology, to destroy the golden- 

 oak scale, an insect that was doing great damage in New Zealand. 

 Several attempts to estahlish this species failed, hut I am now in- 

 formed hy Doctor Miller that the parasite has assumed complete con- 

 trol of the scale. This success is largely due to the work of Mr, E. S. 

 Gourley, of Doctor Miller's staff. One of the European parasites of 

 the European earwig has also been introduced from England. Grass- 

 grub parasites have been imported from Australia. 



In 1926 Tillyard published another paper on the same subject, with 

 no additional facts. 



D. Miller, in the Xew Zealand Journal of Agriculture. June 21, 

 T926, rc])orts on the finding by R. C. Fisher and J. G. Myers of two 

 parasites of the pear imdge (Pcrrisio pyri) in the South of France — 

 the one a s])ecics of Platygastcr and the other a sj:>ecies of Inostcuiina. 

 Colonies were sent to New Zealand in 1925. and the parasites emerged 

 in December and January. The Platygaster bid fair to become estab- 

 lished. 



Later in the same year Doctor Miller published the statement that 

 the Philyc/aslcr sp. referred to above is Misucyclops iiiarchali. The 

 parasite seems to have come out well, 66 per cent being females. 

 J. Muggeridge reported in 1929 that, although this insect survived 

 two or three winters, it had not exercised the degree of control that 

 had been hoped for, even in the orchard where the main liberation 

 took place. 



Tn 1926 and 1927 New Zealand imported three consignments of 

 larvae of Lachnosterna parasitized by the Tachinid, Micro phthalma 

 viichiganeiisis, from Canada. 



In 1927, Doctor Miller reported the direct sending from Australia 

 to New Zealand of a consignment of the eggs of the Eucalyptus wee- 

 vil parasitized by the same Mymarid ' that was later imported from 

 Australia into South Africa and also into Argentina. Doctor Miller 

 tells me that in the 1929-30 season it became established and has the 

 weevil under control. 



Quite recently the little Hymenopterous parasite, Alysia iiiaiuhi- 

 cator, has been imported for use against the so-called " wool maggots " 

 and is giving promising results. Doctor Miller tells me that during 

 the 1929-30 season this parasite has been found breeding naturally 

 in the field.
