especially coccinellid beetles, were also found dead on the rotenone 
dust and bait-spray plots. There were no ill effects on the operators, 
who found DDT to be much less irritating than the rotenone dust.--

NEUROPTERA 
Chry6opidae 
No chrysopid eggs were observed on the fruit or foliage of a 
Bartlett pear orohard in the Sacramento River area, California, which 
had been sprayed with DDT.~ Borden and Jeppson (91) • 
LEPIDOPTERA 
Aegeriidae 
Bembecia marginata (Harr.), the raspberry root borer 
The following materials were applied one, two, and three times to 
separate plots: A spray of 5 pounds of DDT in pyrophyllite (20-80) 
plus l/2 pound of soybean flour in 100 gallons; a 3-peroent DDT dust 
applied with an ordinary hand crank duster at the rate of 40 pounds 
to the acrej and a DDT- di chl or o ethyl ether emulsion which contained 
1 pound of DDT to 100 gallons. Only the DDT- pyrophyllite spray treat- 
ment gave any marked reduction of borers over the check and the single 
spray was nearly as good as two and three applications. In 1943 tests 
the emulsion treatment gave a marked reduction over the check.— N. J. 
Agr. Expt. Sta. (275 ). 
Melittia satyr iniformis Hbn., the squash borer 
This insect was controlled with Gesarol A-3 dust as described for 
Anasa tristis .—Parker (287 ) • 
A 3-percent DDT dust and a spray containing 1 pound of actual DDT 
in 100 gallons of water gave control comparable to a 1-percent rotenone 
dust on squash borer.— N. J. Agr. Expt. Sta. (275 ) . 
In plots treated with 3-percent DDT dust 86 percent of the plants 
were uninfested as compared with 58 percent for plots treated with 35 
percent cryolite and 20 percent for untreated plots.— Tate et aJN ( 342 ) . 
Synanthedon pictipes (G. and R.), lesser peach borer 
A solution of 150 grains of DT7T in 500 cc. of ethylene dichloride 
was emulsified with an equal part of water and painted on infested 
cankers on peach trees in May. Results taken in November showed an av- 
erage of 4 feeding borers in each treated canker and 5.5 in each check.
