PESTS INTERCEPTED, 



Twenty-six packages of fruit and one package of vegetables 

 were found in the baggage of passengers and immigrants from 

 foreign countries. All this material was seized and destroyed by 

 burning. A species of five-leafed pine from Japan in the bag- 

 gage of a passenger was sent back on board of the steamer under 

 a ruling of the Federal Horticultural Board, as all such pine trees 

 are prohibited from landing in the United States or its territories 

 on account of the white pine blister rust {Pcridennium strobi), a 

 very serious disease of pine trees. Two European Bay trees were 

 fumigated on account of being infested with the soft scale (Coccus 

 licspcridum). 



Tucked away among some vegetable seeds and herbs from 

 Portugal was a lonely apple wliich we seized and destroyed. It 

 is just in such material that sonie pest could come into the Terri- 

 tory. Fortunately there exists a thorough cooperation between 

 the postoffice authorities and our department and very little 

 escapes our inspection. 



A small quantity of beans, ])cas and corn was fumigated for a 

 local firm on account of weevil infestation, 



BENEFICIAL INSECTS. 



During the month 7200 parasites were liberated from the breed- 

 ings in the insectary, consisting of the following: For horn and 

 house fly, 1600 African horn fty ])arasites. 2000 Philippine 

 Spalangia, 2000 Philippine Ptcromalids. Vov fruit fly, 250

( )n October 9 T received a shi])ment of jiarasites from Mr. Fred 

 Muir, consisting of one cage with many living Tiphia species, the 

 natural enemy of Jaoinahi oricnfalis and the Japanese beetle, so- 

 called. This sliipnicnl was del'ivered by me to Mr. TT. (). Swezey 

 of the II. .S. 1'. A. and lie lil)erattd 60 specimens at Aiea. A few 

 si)eciiuens were kept for indoor breeding. All the soil containing 

 the parasites was destroyed by burning. On October 27 I re- 

 ceived two cages from Mr. IVTuir which T personally delivered to 

 Mr. Swezey at the H. S. P. A. station. Mr. Swezey has liberated 

 14 parasites from one cage and the other cage is sujiposed to con- 

 tain parasites in the pupal stage, so that it may take a few 

 weeks for the adults to issue. .Ml tliese shii)iu(.'nts are sent 

 lo me for the TT. S. I'. .\., as it avoids delay and safe delivery 

 by using this system. b'very care is taken with tlie material, 

 which is under r|uarantine regulations. I'^rom the second sending 

 c|uite a number of parasites hav been kept for indoor breeding.
