Anth glomus gran die Boh,, the boll weevil 
Various combinations of insecticides were tested against the 
boll wee-ril and ootton aphid in Louisiana. In one test calcium 
arsenate plus 10 percent of sulfur, and 0.5 peroent of rotenone 
was used, but it is not stated what effect the rotenone had on the 
weevil •— Beonel and Pleyd (45)* 
Caloium arsenate-sulfur mixtures with derris effectively ooa- 
trolled the ootton aphid and boll weevil in Mississippi*— MoGerr 
(381 )* 
Barium fluosilicate plus derris (to give a 0*5-percent rote- 
none content) was significantly better than two of the three cryo- 
lites tested with or without the addition of derris for boll 
weevil control* In a second report, Hxe materials tested were cal- 
cium arsenate, with and without derris, and equal parts of calcium 
arsenate and sulfur, with and without derris* No significant differ- 
ence in the degree of boll weevil control was observed between any 
two insecticides in South Carolina .--Rainwater and Bondy (490 , 491 ) * 
Anthonomus mus cuius Say, the cranberry weevil 
In Massachusetts a single application of a spray containing 
15 pounds of derris powder (4 percent of rotenone) and ■§■ pound of 
Areskap per 100 gallons of water, at the rate of 400 gallons per 
acre of cranberries, failed to give a good kill.— Franklin (192 ). 
Anthonomus pomorum (L.), an apple blossom weevil 
In Germany dusts containing dinitro-o-cresol were superior 
to a dust containing derris and pyrethrum.— Thiem (587) • 
Anthonomus pyri Koll. (cinotus Redt.), a pear blossom weevil 
In Germany a preparation of pyrethrum and derris gave good 
control at a high concentration, but one of derris alone was in- 
effective.— J ancke (313 ) ; Thiem (588) . 
Anthonomus rubi (Hbst.), a strawberry blossom weevil 
In Germany this pest on strawberry plants is best controlled 
by a derris dust, or a mixture of derris and pyrethrum at the rate 
of 27 pounds per acre during time of maturation feeding in late 
spring.— Reimann (501) .
