Suppression of the blowflyLucilia sericatausing odour‐baited triflumuron‐impregnated targets

Abstract

Field trials were carried out in 1995 and 1996 on farms in the south-west of England to assess the extent to which odour-baited targets could be used to suppress populations of the ectoparasitic blowfly, Lucilia sericata, in sheep pastures. Targets were constructed from 41 x 41 cm squares of aluminium sheet, covered by white cloth which had been dipped in a mixture of sucrose solution (50% w/v) and the chitin synthesis inhibitor triflumuron (10% suspension concentrate). Each target was baited with approximately 300 g of liver and sodium sulphide solution (10%). Three matched sheep farms were used in the trials. In 1995, triflumuron-impregnated targets were placed around the periphery of sheep pastures at one of the farms in late June, at approximately one target per hectare. In 1996, triflumuron-impregnated targets were placed around the periphery of sheep pastures of a second of the farms in early May, at approximately five targets per hectare. Each year, five sticky targets, used to monitor the L. sericata populations, were also placed in fields at the experimental and the other two farms, which acted as controls. In 1995, the results provided some, although inconclusive, evidence that the triflumuron-impregnated targets had reduced the numbers of L. sericata relative to the populations on the two control farms. In 1996, however, the density of L. sericata on the experimental farm was reduced to almost zero and remained significantly lower than on two control farms throughout the period during which the triflumuron-impregnated targets remained in the field. The results are discussed in relation to the use of triflumuron-treated targets as a practical means of controlling L. sericata and sheep blowfly strike.

Evaluation of the therapeutic and protective effects of ivermectin and permethrin in controlling of wound myiasis infestation in sheep

“…In the trial reported here, the presence of traps reduced strike incidence for ewes and lambs to a fifth of that seen in the control flocks. The reduction in the prevalence of myiasis infestation in farm A is consistent with that reported by Smith and Wall (1998), Ward (2001), and Ward and Farrell (2003). Trapping for the control of important dipteran pest species can be an effective approach under specific circumstances (Haniotakis et al 1991(Haniotakis et al , 1986Prokopy et al 1996Prokopy et al , 2000Broumas et al 2002).…”

Ultrastructure of antennal sensilla of four skipper butterflies in Parnara sp. and Pelopidas sp. (Lepidoptera, Hesperiidae)

“…Biological controls, including the application of sex pheromones, have become increasingly important. Consequently, research of pest antennae has immediate application to the suppression of pests (Smith and Wall 1998). In order to better understand their olfactory system related to the biological control of these four skippers, we researched the type, size, and distribution of antennal sensilla of Parnara guttata (Bremer & Grey), Parnara bada (Moore), Pelopidas mathias (Fabricius) and Pelopidas agna (Moore).…”

A comparison of Lucitraps® and sticky targets for sampling the blowfly Lucilia sericata

“…A considerable amount of research has been undertaken on trapping flies that cause myiasis (Hall, 1995) and this is one method proposed for control of L. sericata . Following extensive trap development (Wall et al ., 1992), a study using triflumuron‐impregnated targets suggested that such a system might be a feasible method for controlling L. sericata and, thereby, sheep strike in England (Smith & Wall, 1998). An alternative system, the Lucitrap ® , has been developed in Australia for control of the closely related species, Lucilia cuprina (Wiedemann) (Denwood et al ., 1999; Horton et al ., 1999).…”
