TNTRODUCTICN 
This is the sixth in a series of papers designed to reviev' all 
available information on the insecticidal uses of rotenone and the rote:^ids 
Part I reviewed tests vj-ith derris, cube, timbo, Tephrosla, Mundulea, ar^ 
their constituents on members of the Gollembola, Orthoptera, Dermapte: 
Odonata, Isoptera, Corrodentia, and Mallophaga, Apparer.tly no testsXdth 
the rotenone plants on Thysanura, Ephemeroptera, or' Plecoptera have/)een 
recorded. Part II reviewed the tests that have been made on Thysar^ptera; 
Part III, the tests on Homoptera; Part IV> the tests on Henpiteraj/Part V, 
the tests on Anopluraj and Part 71, the present paper, reviev.rs tl^e tests 
and recommendations for use on Coleoptera, •

Hot affected by derris, --Van der Lo,an (252) in 1936, 
Reed D.nd Hoolcom (324-) in 1937 reported rotenone dust ineffective 
against adult cigarette b'e'e'tles. Pyrethrum dust v/as slightly more effective, 
but not satisfac^-.ory. 
The adii.lt is definitely susc':^:ptible to derris. --Crauford-Benson 
(90) in 195G. 
The United States Departnient of Agriculture, Bureau of Sntomology 
and Plant Quarantine (3C'8) in its annual report for 1938 reported that 
pyrethrum-dust mixtures containing a high percentage of pj/^rethrins were 
slightly more effective than the dust mixtures containing rotenone, but 
in no instance did the pyrethrum compou.nds give a percentage of kill that 
would be satisfactory in practical operations against adults of the cigarette 
beetle in tobacco ivarchouses of the open type.
