PLANTS INSECTICIDAL, PROPERTIES. 43 



Glover (34i V- 133) reports that camomile flowers, if pulverized 

 when dried and perfectly fresh, have an effect on the oriental cock- 

 roach somewhat similar to that of pyrethum. 



Hirschsohn (4.2) says that camomile powder is inert towards 

 roaches. 



Von Mueller (91, p. 299) says: " In Portugal it is planted under 

 fruit trees for insecticidal purposes." 



Scott, Abbott, and Dudley (83, p. 5, 13) found camomile flowers in- 

 effective against bedbugs and roaches. 



Passerini (66) says that the flowers kill lice, although very slowly, 

 but that they have very little effect against flies and ants. 



Matricaria inodora L. Scentless false-caniomile. Europe, naturalized iu 

 the northern United States. 



Kalbruner (4-7) says that the flowers have a benumbing effect on 

 flies, acting within one or two hours. 



Matricaria matricarioides (Less.) Porter. Synonyms: M. discoidea DC, M. 

 suaveolens Buchenau. Rayless false-camomile. United States, naturalized 

 in Europe. 



Goriainov (29) found a decoction of camomile quite ineffective 

 against Malacosoma neustria. 



Meibomia laburnifolia (Poir. ) Kuntze. Fabaceae. Synonym: Desmodium 

 labumifollum DC. Java. 



Greshoff (33, p. 72) reports that the leaves are used as an insecti- 

 cide. 



Melanthium virginicum L. Liliaceae. Bunchflower. Eastern United States. 



Lyons (53, p. 296) reports that the roots are used as a fly poison. 

 Pammel (64, V- 380) says that " these bunchflowers have long been 

 used to poison flies." 



Melia azadirachta L. Meliaceae. Synonyms: Azadirachta indica Juss., Azed- 

 arach deleteria Medic. Nin tree. East Indies. 



Von Mueller (91, p. 304) says : " Furniture from its wood is not 

 attacked by insects." 



Melia azedarach L. Synonyms: Asedarach commelini Medic, A. odoratum 

 Noronha. Chinaberry. Pride of India. China to India, cultivated in 

 Florida. 



Porcher (68, p. 127, 200) says that peach trees shaded by this 

 tree are never infested by the aphis and that " the leaves and berries 

 of the Pride of India, packed with dried fruits, will preserve them 

 from insects, and will prevent moths in clothes." He further says 

 that the decoction of the berries will, in most cases, prevent the 

 depredations of the black grub, or cutworm. 



Riley's (71, p. 185) assistants report that the decoctions and al- 

 coholic extracts from the leaves, twigs, and berries were very promis- 

 ing. These preparations had considerable effect against cotton cater- 

 pillars, but failed to be efficient. 



Von Mueller (91, p. 305) and Lyons (53, p. 297) report that the 

 leaves are used as an insecticide.
