Etiella zinckenella (Treit. ), the lima bean pod borer 
The United States Department of Agriculture, Bureau of Entomology and 
Plant Quarantine (442) in 1936 reported that derris tested on three species 
of pod borers attacking beans in Puerto Rico was less effective than fluo- 
rine compounds and that none of the rotenone products tested could be 
recommended. 
The Fuerto Rico Experiment Station of the United States Department of 
Agriculture (450) in 1938 reported on work done in 1937, Of the three pod 
borers,, I£aruca testulalis (Geyer), Fundella cistipennis (Dyar), and Etiella 
zinckenella , which infest beans in Puerto Rico, larvae of M. testulalis 
constituted approximately 85 percent of the entire pod-borer population. 
Derris-powder sprays were ineffective in controlling bean pod borers. In 
tests with Challenger lima beans, sprays consisting of derris alone and in 
combination with other insecticides were also ineffective. Tho insecticides 
used were derris alone,' derris in combination with fish oil, derris plus a 
commercial sticker and spreader, derris with nicotine sulfate and soap, 
derris with a proprietary organic thiocyanate insecticide and a commercial" 
sticker and spreader, and a proprietary organic thiocyanate insecticide and 
a commercial sticker and spreader without derris.

Mineola scitulella Hulst 
Haegele (175) in 1932 described spraying tests for the control of this 
species, a pest' of prunes in southwestern Idaho. Cubor, a preparation of 
pyrethrum and rotenone, applied in a concentration of 1:200 to two plots, 
killed 27 and 29 percent, respectively, of the larvae, 
Mineola vaccinii (Riley), the cranberry fruitworm 
The Washington Agricultural Experiment Station (473) in 1930 reported 
the results of tests by Crowley with insecticides against cranberry in- 
sects. Neoton was no more effective than the less expensive pyrethrum 
sprays. Rotenone was tried against the cranberry fruitworm at the rate' of 
3 ounces to 100 gallons of water. It killed fruitworm larvae at this 
strength and also acted as a repellent to chewing insects for several days 
after the plants were sprayed with it. 
The Massachusetts Agricultural Experiment Station ( 270 ) in 1937 re- 
ported that in tests against the cranborry fruitworm a spray of 10 pounds 
of derris powder (4 percent rotenone) and 2 pounds of fish-oil soap in 100 
gallons of water, applied at the rate of 400 gallons per acre on July 13, 
controlled tho insect much better than any insecticide ever tried before. 
It was estimated that the worms took less than 10 percent of the berries, 
as compared with 35 to 90 porcont on surrounding areas. The treatment did 
not scorn to affoct the vinos or crop. Tho derris spray was also used early
