Mantidae 
Stagmomantis sp., a praying mantis 
Individual praying mantis placed on sheets of paper dusted with a 
1 percent DDT-kaolin powder and covered with a beaker were totally para- 
lyzed in 50 to 70 minutes and dead in 600 to 650 minutes. — Sen (311 ) . 
DERMAPTERA 
Forficulidae 
Forficula auricalaria L., European earwig 
Twelve adults were placed in a cloth cage, the inside of which was 
lightly dusted with Gesarol A-3 dust (3 percent DDT), and complete mor- 
tality resulted within 24 hours.— Ross (306 ) . 
IS0PTERA 
Armadillididae 
Armadillidium vulgar e (Latr.), sowbugs 
In a laboratory test sowbugs placed in glass jars with a bait of 
ftDT-rye flour (1-9) were all killed in 5 days. In comparison paris green 
caused complete mortality in 4 hours*— Ross (306) . 
Rhinot ermit idao 
Termites 
Preliminary work at Asheville, N. C, and Beltsville, Md», indicates 
that DDT is very toxic to termites, both as a soil poison and in treated 
wood. In the latter case, however, it is of limited value because it has 
no fungicidal properties. Tests with fiberboard are under way m the 
tropics. Fabrics treated with 5-percent solutions of DDT have been re- 
sistant to termite attacks, and tests with lower concentrations are now 
being conducted. Fabrics treated with DDT were severely damaged by mil- 
dew and decay.— Craighead and Brown (125) . 
MALLOPHAGA 
Menoponidae 
Eom enacanthu s stramineus (Nitz.), the chicken body louse 
DDT in concentrations up to 10 percent (Neocid A-5 ard A-10) did not 
afford an experimental bird any better protection against the chicken
