Derris may merit further attention. — Dumbleton and Dick (150). 
Hesperiidae 
IJrbanus proteus (i.), the bean leaf roller 
In Florida rotenone is recommended against this pest on beans 
in home gardens, after the pods form.— Watson ( 657 ) .

Plutella maculipennis (Curt.), the diamondback moth 
Field tests near Norfolk, Va., with rotenone-nicotine dust com- 
binations indicated that these materials could be safely combined to 
control both aphids and diamondback moth larvae on collards. These 
dusts were more effective for the control of the moth than rotenone 
alone.—Walker and Anderson (648 , 650 ) . 
Sprays or dusts containing Derris or Loncho carpus were recommend- 
ed in England in 1942.— Walton ( 655 ) . 
Derris resin was toxic to the eggs in England. — Potter and 
Tattersfield (471). 
Derrisol may be used for the control of this moth on cole crops 
in South Africa. — Schultz (527 ) . 
This pest on cabbages in Queensland can probably be controlled 
by the -use of lead arsenate dust before the cabbages head, and a 
spray of summer oil afterwards in place of dusts or sprays of derris 
which, in 1942, was difficult to obtain.— Veitch (637). 
Derris dust or spray can be used against the larvae which attack 
turnip tops in New Zealand.--Pritchard ( 476 ) . 
A 0.1-percent nicotine spray, applied at 4-day intervals in 
Malaya, gave better control on cabbage than did derris or pyrethrum 
sprays.— Corbet t and Pagden (121 ) . 
In New South Wales cabbages should be dusted every 7 to 10 days, 
with equal quantities of lead arsenate and kaolin during early 
growth, and with derris and kaolin (1:8) when the plants are heading. — 
New South Wales Department of Agriculture (443 ) .
