State of J^ew York into or through any other State, Territory or 

 District of the United States. 



Quarantine No. 19 was published December 10, 1914, for the 

 purpose of prohibiting the importation of all citrus nursery stock, 

 including buds, scions, and seeds, from Europe, Asia, Africa, South 

 America, North America outside of the United States, and for- 

 eign Oceanic countries and Islands on account of a very serious 

 disease of the Citrus known as the Citrus Canker. The disease 

 Citrus Canker has only recently been found in Florida, U. S. A., 

 and from accounts has done considerable damage to citrus groves 

 in "various" sections of that State. The disease must have been 

 present there for some time but like so many similar diseases, was 

 overlooked or taken for scab, scaly bark or Anthracnose. It has 

 been found on Citrus trifoliata from Japan. I have condemned 

 several shipments of young citrus trees coming into the Territory 

 showing some scabby growth, and some fruity which is prohibited 

 and showed signs of a disease which no doubt was Citrus Canker. 

 Under the enforcement of Quarantine ]^o. 19 all danger of import- 

 ing infested citrus plants in the future is passed. 



INSECT PESTS AND REMEDIES. 



During the past two years the following insects have proven 

 quite a menace to plant life in and around Honolulu as well as in 

 some districts on the other islands : 



Japanese Rose Beetle (Adoretus tennhnaculatus) . 



Probably this beetle has caused more annoyance to people 

 than any other pest we have. Owing to severe dry spells during 

 the early sumnier, especially in 1914, there was a very material 

 increase of this pest in the drier sections. ISTot only was the dam- 

 age reported by the flower lover, but the vegetable grower had 

 great destruction wrought to his beans, egg plant and other tender 

 growth, and at times it no doubt seemed__intolerable. There is no 

 question but that the adult and larva of this species is kept in 

 check by the beetle fungus when climatic conditions are right, 

 that is to say, when we have warm moist weather to induce the 

 spread of the fungus. But, when such conditions do not exist for 

 a period of six months, the beetle becomes very abundant and 

 very destructive. Collecting beetles at night has been tried by 

 some who cared a great deal for their plants, but while many 

 people will do this collecting regularly and conscientiously the 

 next door neighbor will not bother about the pest, and after his 

 plants have fed a multitude of beetles and they are left leafless 

 the beetles soon migrate to the neighbors' gardens and all the work 

 has to be done over again, which at best is most discouraging.
