PLANTS — INSECTICIDAL PROPERTIES. 43 
Glover (31f, p. 183) 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 i4~) 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-camomile. Europe, naturalized in 
the northern United States. 
Kalbruner (J/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, naturalize!. 
in Europe. 
Goriainov (29) found a decoction of camomile quite ineffective 
against Afal-acosoma neustria. 
Meibomia laburnifolia (Poir. ) Kuntze. Fabaceae. Synonym: Desmodium 
labuniifoliiim 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) report- that the roots are used as a fly poison. 
Pammel (61}.. p. 380) says that " these bunchflowers have long been 
used to poison flies." 
Melia azadirachta L. Meliaceae. Synonyms: Azadirachta indica .Tuss.. Azed- 
arach deleter ia Medic. Xin tree. East Indies. 
Von Mueller (91. p. 301}) says: "Furniture from its wood is not 
attacked by insects/' 
Melia azedarach L. Synonyms: Azedamch commelini Medic, A. odoratum 
Xoronha. 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. 183) 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.
