Rach islet was surveyed identically. Walk-through surveillance with insect nets and collecting equipment was conducted. breeding sites and harborages were sampled. All possible Light traps were set out poy in areas where wind shelter was provided to sample nocturnal activity. Rodent surveillance was visual and with traps. Have-a-Heart traps were set in association with burrows, nests, high activity areas and harborage. Laboratory areas provided by Mid Pacific Marine Laboratory (MPML) and equipment indigenous to the survey teams provided ample work and identification requirements. Insect identifications were made microscopically with the use of appropriate keys. The following islets were surveyed: Enewetak 2) Medren 3) Jedrol 4) Japtan 5) Ananij (Walt) ~ (David) (Bruce) Billae (Wilma) 8) Alembel (Vera) 9) Lojwa (Ursula) 10) <Aomon (Sally) 11) Ae} RESULTS: - (Olive) Enjebi (Janet) ai The predominanat problem on the atoll is the large population of rats.
