RICE WEEVILS. 



Tliree packages of sorghum seed came by mail from New York, 

 that were found slightly infested with ''rice weevils" {Calandra 

 oryra). This we successfully treated with the fumes of carbon 

 bisulphide. 



INFESTED MANGO SEEDS. 



On Sunday, June loth, the transport '"Sheridan" arrived from 

 Manila. In her mail she had a tin box of mango seeds packed 

 in fine charcoal. Upon inspection the insides of the seeds were 

 seriously infested with very small eight-legged silvery mites. 

 The owner was notified and the condition of the seed was shown 

 to him, after which the seed and packing, including the wrapper, 

 were burned. 



ISJANGO WEEVIL. 



In my report to you, dated October 2, 1905, I called your at- 

 tention to the existence of a mango fruit pest that was found in- 

 festing the seeds of that fruit in two sections of Oahu. Mr. 

 Austin and I immediately visited the district, but found the crop 

 was over for the season. Upon an examination of a few dry 

 seeds found under the trees we discovered several living larvae 

 and beetles. We called the attention of the superintendent of 

 the estate to the fact and renuv:sted him to liave all seed carei'dly 

 collected and burned, which was done. During the present crop 

 of mangoes we have made a careful inspection to ascertain the 

 extent of its spread and am sorry to report that it is more 

 widely distributed than any one that has taken interest in this 

 was aware. 



Mr. Alustin and I visited ^Nloanalua and the valley adjacent 

 and estimate that over seventy-five per cent, of the present crop 

 contains the pest from verv small larvae to pupae. No mature 

 beetles were found during our examination, even with collecting- 

 sheets. 



During 1905, Mr. D. L. Van Dine first called public attention 

 to this beetle on Oahu, but previous to that Mr. S. Wilder called 

 the attention of his brother, Gerrit, to a beetle found by him in a 

 mango seed from Moanalua, which he submitted to Prof. R. C. 

 L. Perkins of the Hawaiian Sugar Planters' Association. Mr. 

 Van Dine estimated that sixty per cent, of the fruit was attacked,
