Autodissemination may be effective against the Japanese beetle, Popillia ja
ponica Newman, in situations where habitats of tis larvae are inaccessible.
Trapping systems with attractants for both male and female Japanese beetle
s are commercially available. We fabricated an inoculation chamber which fi
ts between the top of a standard Trece Catch Can(TM) Japanese beetle Trap a
nd its holding canister. Beetles which are attracted to the trap fall throu
gh a hole in the inoculation chamber and land on a mesh screen. A partial f
unnel and canister attachment from a metal Ellisco Japanese Beetle Trap was
secured beneath a hole in the floor at the opposite end of the chamber. A
10-cm section in the middle of the box, between the entrance hole in the ro
of and the exit hole in the floor, allows space for a dish containing the i
noculum to be placed into the chamber through a door in the side of the uni
t. The trap has been tested with Metarhizium anisopliae (Metschnikoff) Soro
kin as the pathogen. Beetles emerging from the device in the field were cap
tured and returned to the laboratory where the presence of conidia and mort
ality to adult beetles from the fungus were confirmed.
