“…Currently, the prophylaxis against flystrike relies on synthetic insecticides, such as organophosphates and insect growth regulators (benzoylphenyl ureas, cyromazine and dicyclanil) [16; 17; 12] and, especially for Merino lambs in Australia's extensive wool industry, on painful surgical husbandry procedures such as the docking and the mulesing [18; 19]. However, the side effects of synthetic insecticides, such as the development of insect resistance [20], the harmful effects on sheep [21], farmers [22], and the environment [23], as well as the rising concerns about animal welfare [24] have made alternative strategies a high priority.…”

Toxicity and oviposition deterrence of essential oils of Clinopodium nubigenum and Lavandula angustifolia against the myiasis-inducing blowfly Lucilia sericata

Cutaneous myiasis is a severe worldwide medical and veterinary issue. In this trial the essential oil (EO) of the Andean medicinal plant species Clinopodium nubigenum (Kunth) Kuntze was evaluated for its bioactivity against the myiasis-inducing blowfly Lucilia sericata (Meigen) (Diptera Calliphoridae) and compared with that of the well-known medicinal plant species Lavandula angustifolia Mill. The EOs were analysed and tested in laboratory for their oviposition deterrence and toxicity against L . sericata adults. The physiology of EO toxicity was evaluated by enzymatic inhibition tests. The antibacterial and antifungal properties of the EOs were tested as well. At 0.8 μL cm -2 , both EOs completely deterred L . sericata oviposition up to 3 hours. After 24 h, the oviposition deterrence was still 82.7% for L . angustifolia and the 89.5% for C . nubigenum . The two EOs were also toxic to eggs and adults of L . sericata . By contact/fumigation, the EOs, the LC 50 values against the eggs were 0.07 and 0.48 μL cm -2 while, by topical application on the adults, LD 50 values were 0.278 and 0.393 μL per individual for C . nubigenum and L . angustifolia EOs, respectively. Inhibition of acetylcholine esterase of L . sericata by EOs (IC 50 = 67.450 and 79.495 mg L -1 for C . nubigenum and L . angustifolia , respectively) suggested that the neural sites are targets of the EO toxicity. Finally, the observed antibacterial and antifungal properties of C . nubigenum and L . angustifolia EOs suggest that they could also help prevent secondary infections.

“…Use of the same or a related insecticide twice during a wool growing cycle is not recommended on the grounds that it unnecessarily increases selection pressure for resistance development. In New Zealand, some L. cuprina populations also display low‐level resistance to dicyclanil and several New Zealand populations of L. sericata are more than 20‐fold resistant . The flystrike season in New Zealand typically begins around November and extends until the following April.…”

“…The flystrike season in New Zealand typically begins around November and extends until the following April. During this time, sheep may require prophylactic treatment at least twice . The apparently worse resistance situation in New Zealand may reflect the more intense selection for resistance development associated with second and third insecticide treatments within the flystrike season and should be a warning of what could happen in Australia if these products are over‐used.…”

“…Laboratory assays on larvae of blowflies ( L. cuprina and L. sericata ) collected from farms in New Zealand in the years 2010–2011 identified field strains of both species with decreased susceptibility to triflumuron with one L. sericata strain showing an RR of >14,000 and several other L. sericata strains with RR > 1000. The highest RR determined for L. cuprina strains was 16 [284].…”

Six benzoylphenyl ureas are currently used in formulations approved as veterinary medicines: diflubenzuron for fly control mainly on cattle, lice and blowfly strike control on sheep, and lice control on farmed salmonids; lufenuron for flea control on dogs and cats and for lice control on farmed salmonids; triflumuron for lice and blowfly strike control on sheep; fluazuron for tick control on cattle; teflubenzuron for lice control on farmed salmon; and novaluron for fly and tick control on cattle and for flea control on dogs. Resistance to diflubenzuron and triflumuron has already been reported for sheep body lice and blowflies, and to fluazuron in cattle ticks. These and other minor veterinary usages, as well as the current status of resistance, are reviewed and perspectives for future opportunities are discussed based on unexplored potentials and threats posed by future resistance development.

Thein vitroresponse of field strains of sheep blowfliesLucilia sericataandL. cuprina(Calliphoridae) in New Zealand to dicyclanil and triflumuron

Abstract: Flystrike is a debilitating and occasionally lethal disease in sheep such that efficacious sheep dips have prophylactic value in reducing the prevalence of the condition.
