Traps and baits for flies (Diptera) on Pacific Islands

Studies conducted on Oahu, HI, and on islands of the Kwajalein Atoll, Marshall Islands, demonstrated that adult house flies, Musca domestica L., were attracted to a mixture of cooked rice and chicken and to a commercial bait, whereas adults of Chrysomya megacephala F. and Musca sorbens Wiedemann were attracted to shark fluids or to ripe breadfruit. M. domestica and M. sorbens could be captured in standard inverted-cone traps, whereas C. megacephala could be captured in traps fitted with horizontal entry cones or in cone traps in which the bait was placed inside the cone chamber. M. sorbens and C. megacephala were killed by horizontal electric grids placed over yellow plastic or paper at ground level. M. sorbens was attracted to 15-cm cubes, but not to larger objects.
