The maggot was sent to the Finnish Museum of Natural History, Helsinki, Finland, and identified as a third-stage larva of Cochliomyia hominivorax (Coquerel), the New World screwworm
Their lab's successful cryopreservation of the house fly led to the development of a protocol for cryopreserving screwworms
, a devastating insect pest that burrows into and eats the flesh of warm-blooded animals.
These ticks are easily killed by instilling in the ear a mixture of mineral oil with a little lindane screwworm
smear mixed in.
Today, the ARS Screwworm
Research Laboratory (SRL) in Kerrville, Texas, and in Panama, in cooperation with APHIS, is developing more effective and less costly methods of producing sterile males.
Today, USDA's Animal and Plant Health Inspection Service (APHIS) leads the screwworm
fight, but ARS continues to lend its support through basic and applied research.
is the common name of a pest native to the tropical areas of North, South and Central America that causes extensive damage to domestic livestock and other warm-blooded animals.

When Aruba, a tiny island in the Caribbean, had an outbreak of screwworm
in March 2004, it contacted ARS remote-sensing specialist Pamela L.
The technique was first used to rid North America of livestock-parasitizing screwworm
Crystal (1967) reported significantly decreased survival rates and fertility of screwworm
, Cochliomyia homini-vorax (Coquerel) (Diptera: Calliphoridae), exposed to 100% C[O.
Using cryopreservation techniques, ARS entomologists can now freeze screwworm
fly embryos--to later thaw and rear them to adulthood.
This technique has proven to be effective against fruit flies (Enkerlin 2005), the screwworm
, Cochliomyia hominivorax (Coquerel) (Vargas-Teran et al.
