Cerambycidae 
Oberea blmaculata (Oliv.), the raspberry eane borer 
In New York best results were obtained with a spray contain- 
ing 5 pounds of derris (4.8 peroent of rotenone) and \ pound of soy- 
bean meal per 100 gallons of water, 1 application of -which gave 90.8 
percent control. One or 2 applications of a 1-percent rotenone dust, 
and 2 applications of a spray containing 1 pint of a commercial rote- 
none extract (2.5 percent of rotenone) in 100 gallons of water were 
less effective.— Ifcindinger (436) ; Slate and coworkers (54 4, p. 54) • 
This borer was controlled best by rotenone sprays, and moderate- 
ly well by rotenone dust.— Parrot t (457) . 
Saperda Candida F., the reuadheaded apple tree borer 
In New York insecticides were injected into larval tunnels in 
apple trees. One and five-tenths peroent of rotenone extract with 
ethyl alcohol (1*4), caused 71 peroent mortality, while 5 percent 
rotenone extract in aoetone, caused 100 percent mortality of the 
larvae*— Hess (283 , p. 81)* 
Unidentified oerambyoids 
Longioeras are important pests of fig trees in Japan* In tests 
lead arsenate, pyrethrum, and derris were injected into the mines of 
these insects in the stems and branches of fig trees. The best re- 
sults were given by the arsenate and pyrethrum, which killed 96 and 
83 peroent of the larvae, respectively.— Kusunome and Umetsu (346 ) • 
Chry8omelidae 
Agelastloa alni (L.), an elder beetle 
This insect, attacking fruit trees in France in 1939, was con- 
trolled by arsenical sprays. Preparations containing rotenone and py- 
rethrum also gave good results.— Feytaud (181 ). 
(Ceratla ) Aulacophora hilaris (Boisd.) 
In New South Wales cucurbit plants can be dusted with derris, or 
a mixture of pyrethrum and flour (l:4), both of which destroy many of 
these beetles and prevent reinfestation for 1 or 2 days.— New South 
Wales Department of Agriculture (441) . 
In South Wales plants may be dusted with a mixture of pyrethrum 
and kaolin or flour (1x4), Derris dust may also be used.— New South 
Wales Department of Agriculture (444).
