Did the sterile insect technique or weather eradicate screwworms (Diptera: Calliphoridae) from Libya?

摘要: The American screwworm, Cochliomyia hominivorax Coquerel, was detected in northwestern Libya 1988. By August 1990, a screwworm epizootic extended over 26,000 km2 but collapsed December and disappeared April 1991. relative contributions of winter weather sterile insect releases on eradication were assessed by using temperature data population demography. A overwintering threshold mean =9.7°C for 3 mo is supported strongly published experimental epizootiological data. In Libya, temperatures above this at Zawia, Sorman, Tripoli stations. At Gharyan, the interior highlands, from 1 1990 to 28 February 1991 less than putative threshold. No kill pupae or adults likely as result low near any station 1990–1991. Evidence 1990–1991 provided detection natural infestation trap captures numerous wild adult females February, March, April. Successful highly probable coastal plain unlikely much highlands. high rate animal inspections personnel achieved 30% chance detecting case domestic animals. Generation times expectation life among feral flies estimated. Case reports January June consistently estimates based historical experience 1989–1990 Texas 1962–1983. Phenological simulations mating rates supports contention that fly led greatly reduced incidence time declared October
