“…Existing control measures at the time included topical larvicides, which although effective required significant labor for topical application and continued surveillance. 107 By the early 1950s, a technique was developed involving sterilization of the male fly with radiation. Aerial release of these laboratory-reared sterilized flies ensued, and by 1966 the NWS was considered to be eradicated from the United States.…”

“…Examples of pure nuisance flies are the house fly (Musca domestica), the face fly (Musca autumnalis) and the headfly (Hydrotaea irritans) (Thomas and Jespersen, 1994;Malik et al, 2007). Biting and bloodsucking flies, such as the stable fly (Stomoxys calcitrans) and the horn fly (Haematobia irritans) (Byford et al, 1999;Foil and Hogsette, 1994;Presley et al, 1996), and myiasis-causing flies, such as sheep blowflies (Lucilia cuprina, Lucilia sericata), the nasal bot fly (Oestrus ovis) and the New World screwworm fly (Cochliomyia hominivorax) (Hall and Wall, 1995;Reichard, 1999;Wall et al, 2000;Otranto, 2001;, in addition to being a nuisance, also cause significant blood loss or tissue damage in livestock animals. Furthermore, many cyclorraphan flies are mechanical vectors of bacterial diseases such as anthrax (Fasanella et al, 2010) or bovine summer mastitis (Hillerton et al, 1990), and transmit nematodes such as Thelazia eye worms (Otranto and Traversa, 2005) or Habronema species (Traversa et al, 2008).…”

“…Nevertheless, there are no reported examples of efforts made to replace sentinel animals with a synthetic chemical odour source. Such a bait could find application both in bait‐stations designed to monitor the efficacy of SIT programmes and as a complement to SIT and veterinary measures designed to suppress adult C. hominivorax populations (Cunningham et al , 1992; Lindquist et al , 1992; Reichard, 1999).…”

Field studies were conducted in Mexico to investigate the possibility of replacing sentinel animals as baits for female New World screwworm Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) with a synthetic odour-bait composed of compounds identified from wounds infested with the larvae of C. hominivorax. Studies using sheep held in stanchions surrounded by an incomplete ring of electrified nets showed that both male and female C. hominivorax were attracted to an unwounded animal (ratio of male : female flies caught 1.11 : 1.00), although they were not observed to land. By contrast, catches associated with unwounded sheep with larval wound fluid applied to shaven shoulders suggested that female C. hominivorax were attracted to (male : female ratio of electrified nets catch 0.14 : 1.00) and landed on the wound fluid but male flies did not respond (male : female ratio alighting on fluid 0.05 : 1.00). In related studies the attractiveness of synthetic blends of 25 electrophysiologically active compounds identified in fluids associated with wounds infested with the larvae of C. hominivorax were tested. The acidic components of the wound fluids were found to attract and elicit a landing response from both male and female flies, whereas the non-acidic components alone caught only low numbers of flies. However, the numbers of male and female flies that were attracted to and landed on a synthetic bait could be increased significantly by increasing the proportion of non-acid to acid components in the lure. In some replicates the most effective blend caught a number of C. hominivorax comparable to that caught by a standard synthetic attractant, Swormlure-4, although, unlike with Swormlure-4, the catch was predominately composed of female flies. It is uncertain whether Swormlure-4 contains compounds that elicit a landing response from male C. hominivorax or whether the synthetic and natural wound odours contain compounds that inhibit a landing response from male C. hominivorax. Further work is required to simplify the blend of compounds needed to attract female flies and to better understand the role of the compounds that elicit behavioural responses from both male and female C. hominivorax before a synthetic substitute can be fully developed to replace sentinel animals.
