 of insects and fungus diseases in Hawaii. I'.ricf notes are included ou insect 

 I)ests found on slii[inients of plants wliidi were lield in (luarantine. I'articular 

 atto'ition is j;iven to a discussion of the various importations of beneficial 

 insects whidi iiave l)een made into Hawaii. Recently considerable effort has 

 lu'cn devoted to a study of Euvviht linimtiviis and other natural enemies of the

Report of the government entomologist, K. K. (Jkeen (Vires, and Agr. Jour, 

 h'oii. Hot. (Itinl. Cci/loti. .} itnOG). .\o. 22. pp. 287-29.'t). —Muny of the well- 

 iuiown tea pests continued to give trouble during 100(5. The use of sulphur 

 against tea mites has been more* extensive. The remedy is effective, but some 

 complaints have been made of injury to the tea foliage from its u.se. 



The cultivation of Kickxia rubber has been renderi'd almost impossible by the 

 attacks of Caprinia conchi/lalis. This pest may be controlled by repeated spray- 

 ing with arsenicals. Notes are also given on other pests of rubber and cotton. 



Attempts are being made to establish apiculture in Ceylon and the govern- 

 ment is encouraging the extension of sericultiu'e. 



Report of State nursery insijection, J. G. JMooKi; ( WiscuNshi Sht. Rpf. I'.lllC), 

 lip. 231-239). — Thus far considenible success has been had in keeping dangerous 

 insects and fungus diseases in Wisconsin under control. Notes are given on 

 the prevalence and treatment of oyster-shell bark-louse. <'ottony maple scale, 

 woolly aphis, peach aphis. imi)orted willow weevil, crown gall, apple blight, etc. 



Injurious insects and their control, W. T. Clarkr (Alahamu Col. Sta. Bui. 

 t3!>. pi>. 20). — Brief mention is made of the kinds of damage which may be done 

 to cultivated crops tiy insects. Formulas are given for the preparation of Paris 

 green, arsenate of lead, poisim baits, and lime-sulphur wash. Attenticm is also 

 called to the importance of mechanical methods of destroying insect pests and 

 tile use of trap crops for this purpose. 



RepoVt of the entomologist, C. P. Gillette {Colorado Sta. h'pt. HXld. pp. 

 I'i2-l.'i!)). — During the year under report att(»ntion was given to the melon 

 louse, grasshoppers, . cottony maple scale, oyster-shell scale, peach-twig borer, 

 peach borer, codling moth, etc. An outline is given of the entomological work 

 proposed for the coming year. The field entomologist, E. P. Taylor, reports ou 

 Iir.ictical work in controlling insect pests, the collection of economic insects, 

 inspection of orchards, and attendance at farmers' institutes. It is stated 

 that despite the excellent s[)raying equipment in Grand Valley, tlie codling 

 moth does a great amomit of harm. This is attributed to a lack in thoroughness 

 of method, deficiency in s[)rayiug material, and incomplete knowledge of the life 

 history of the moth. 



Some insects injurious to wheat during 1905-6, L. Bruner and M. II. 

 SwENK (Xcbntxhd >st(i. Bui. DU, pp. 36, pi. J, fi(/><!. I'l). — In this account of wheat 

 insects particular attention is given to the Hessian fly. which caused a great 

 amount of damage in Nebraska for a nmiiber of years, but diminished in muii- 

 bers when conti'ol methods suggested b.v the station were put into practice 

 by farmers. The habits and life history of the pest are discussed in detail 

 ;ind the standard methods of control .-ire recoumiended. 



Biological and economic notes ;ire also given on the wheat-stem maggot, frit 

 Hies, wheat midge, wheat straw-worms, stalk borer, and grain jdant louse. 



Report of the entomologist and plant pathologist, \V. ^'. Tower (Porto 

 A' /CO .S7f/. Rpt. IDOl), pp. 2.')~28). — Some of the orange groves In the island are 

 infested with red .scale. A fungus disease has r(>cently been observed to hold 

 this insect in check. One of the most serious pests of the orange is the i)urj)l(> 

 scale, which may be best controlled by the use of linuKsulphur wash. This 

 gives better results than kerosene or crude oil emulsions. Brief notes are also
