REPORT or HORTICULTURAL-QUARANTINE IN- 

 SPECTION WORK. 



Honolulu, October 30, 1907. 



To the Honorable Board of 



Commissioners of Agriculture and Forestry, 

 Honolulu, T. H. 

 Gentlemen : — 



Since my report to you, dated the 2n(f instant, there have ar- 

 rived twenty-five steam and sailing vessels from outside the Terri- 

 tory requiring inspection by this Department. 



On October 3rd the S. S. "Hilonian" arrived from San Fran- 

 cisco and on board were found four crates of turnips infested with 

 ^.he larvae an^l pupae of the raddish-cabbage root maggot 

 (Phorbia brassicac). These vegetables, including the cases, weje 

 destroyed by fire. 



(^n the 7th of October the S. S. "Sierra" brought from San 

 Francisco five cases of quince badly infested with codling mouth 

 larvae (Carpocapsa povioncUa). This is not a new pest for that 

 fruit but, as the quantity of worms found made the fruit practi- 

 cally worthless, the consignment was burned. 



On October nth the S. S. "Nippon Maru" brought no pack- 

 ages of rubber seeds, some of which had been damaged and were 

 found to be swarming with a species of mite. The seeds were 

 treated with the fumes of carbon bisulphide. Mites, as a rule, are 

 difficult to destroy, but with the above chemical these succumbed 

 readily in the course of an exposure of about two hours. The 

 same chemical was again used in the disinfection of some in- 

 fested imported Japanese rice. 



Consignments of lemons and other fruits from Australia were 

 ordered sent out of the Territory on account of the danger of in- 

 troducing the fruit flies of that country. 



Since my last report I have received an interesting letter from 

 ^Nlr. Geo. Compere, who is at present in India collecting bene- 

 ficial insects for Western Aiistralia and California. Mr. Com- 

 pere has again succeeded in securing parasites upon fruit mag- 

 gots, one species of which pest was introduced in the Territory 

 some years ago, and has since practically wiped out the formerly 

 profitable melon crops of these islands. Among the parasites se- 

 cured by Mr. Compere, and being bred in India by him for intro- 

 duction into West Australia, is one on cucumber, which will no 

 doubt be beneficial to us here when introduced and established. 

 Mr. Compere is meeting with many difficulties owing to distance 

 in transportation, but states that he will this time be successful
