254 EXPERIMENT STATION RECORD. 



The chief investigations of the year were those of the insects affecting cotton, 

 a bulletin relating to which has been previously noted (E. S. R., 22, p. 58). 

 Three species of cutworm, namely, the black cutworm, the army worm, and 

 Spodoptera viauntia were particularly injurious to crops during the winter 

 and spring. The army worm was found for the first time injuring rice, serious 

 losses being reported from all the rice producing sections of the islands. At 

 two places on Kauai, and at Kalihi, Punaluu, Hauula, and Kailua on Oahu, the 

 damage amountpd to from 10 to 60 per cent of the crop. 



A tortricid moth {Anwrhia emigratellu) which attacks a great variety of soft 

 and succulent plants, including citrus, alligator pear, guava, passion-tlower 

 vine, tomato, etc., is rapidly increasing and gives pi'omise of becoming a serious 

 pest of fruits. The introduction of parasites of bean weevils from Texas is 

 said to be under way. Cultures of entomophagous fungi have been received 

 from Florida and will be tried on destructive Coccidae. 



Caterpillars of two species of moth, Ciifpfoblobcs alicna and A. emigratella, 

 were found to prevent the natural formation of pods of the algeroba, on the 

 beans of which stockmen depend largely for winter fodder. 



Insect notes for 1909, O. A. Johannsen {Maine *S7«. Bui. 177, pp. 2l-lfli, 

 pJ'<. 3). — This bulletin contains brief accounts of the insects of greatest im- 

 portance in Maine during the season of 1909. 



The saddled prominent ( Hrterocampa guttivitta) though less injurious than 

 the previous year was a source of considerable injury to the birch and other 

 deciduous foi'est trees. Descriptions of the earlier stages are given of several 

 of the species noted, including the spindle woi*m [Achatodcs zx'(c), birch leaf 

 Bucculatrix (B. caimdcnsiseUa), apple leaf sewer (Ancylis [I'hoxopteris] 

 nubectilana), a fungus gnat (Mycctobia divcrgenn), two species of crane flies 

 ( Ctenophora apicata and Trichocera regelationis), a potato maggot {Droso- 

 phila busckii), and a beetle {Carpophilus honiptenifi) found feeding on dried 

 peaches. 



Other insects the occurrence of which is noted are Acrnbasis rvbrifascicUa, 

 abundant on sweet fern, the fall webworm, gipsy and brown-tail moths, cigar 

 case-liearer, lesser apple worm, the salt marsh cateri)illar and Diacrisia (Spilo- 

 soma) virginica attacking garden crops, San Jose scale, cottony grass scale 

 (Eriopeltis festucw), grape leaf hopper, the downy physllid of alder (Psylla 

 floccosa), several species of Aphididiie, the grass thrips {Atmphothrips striata), 

 a false crane fly {Rhyphus punctatus), mosquitoes, the currant fruit fly, a 

 tachinid fly (Frontiiia arcMppivora) i)arasitic on Anosia plexippus, the bumble 

 flower beetle (Euphoria iiida) which attacked apples in storage, a scolytid 

 beetle (Pityophthorus conipcrdit) which mines in pine cones, shot borer 

 (Xylcborus dispar), pine borer {Monohammus scut<'1hitu>i), and the spruce 

 (Loptiyriis abietis) and larch {'Scmntus crichsonii) saw flies. 



Insects of fi.eld crops, R. H. Pettit (Michigan Sta. Bui. 258, pp. 35-8'/, figs. 

 51). — This bulletin is the third of a series dealing with the insects affecting 

 different classes of crops, of which the first and second have been previously 

 noted (E. S. R., 15, p. 1089; 17, p. 990). Under crop headings summarized 

 accounts are given of the more important pests of field beans, clover, corn, oats, 

 field peas, timothy, and wheat. 



Report of the department of vegetable patholog'y, W. T. Horne (Estac. 

 Cent. Agron. [Cuba] Rpt. (English Ed.), 2 (1905-1909), pt. 1, pp. 72-90, pis. 

 Jf). — This report includes a brief account of cane insects, tobacco insects, citrus 

 insects, and insects affecting leguminous crops. 



First report of the state entomologist upon the horticultural inspection 

 work for the year 1909 (Ann. Rpt. Bd. Hort. Colo., 1909, pp. 115-137, pis. 2).— 

 Twelve counties in the State are reported to have horticultural inspectors.
