Under the Simarubeae it is stated that Sanadera of Gaertner, 
to which Adrien has referred Vittmannia Vahl and Niota Lam. , 
is found in Madagascar and Java and in Ceylon and the southern 
parts of India. In the Himalayas there is a representative of 
this family in Hima quassioides of Hamilton, referred by Dow 
to Simaha . The Simarubeae are as closely allied botanically 
as in the possession of a similar intense, puro bitterness, 
diffused over every part, owing to the presence of the bitter 
principle quassine (p. 158).

As a remedy against the sucking pests of mustard, Eurydema 
ornatum , E. festivum , and Carpocoris purpureipennis , the author 
recommends spraying with quassia and green soap emulsions. In 
his experiments these insecticides killed 20 to 50 percent of 
the larvae. The spraying must be done during flowering and 
after it is over. He describes the mode of preparing the 
emulsions and gives the cost of a vedro (2.7 gals.) as about 
6 cents for quassia.

Owing to the increased price of tobacco, quassia emulsion 
was used against aphids. Four pounds of quassia are boiled for 
about 2 hours in &-l/ 2 or 9 gallons of water; the decoction is 
left overnight to settle and is then filtered; 3 pounds of 
soft soap dissolved in hot water are then added and water to 
make a total of 27 to 30 gallons.
