Treatment of Pastures with Diflubenzuron Suppresses Horn Fly, Haematobia irritans (Diptera: Muscidae) Development
Diflubenzuron is an insect growth regulator labeled for application to pastures and rangeland to suppress grasshopper (Orthoptera: Acrididae) populations. Livestock are permitted access to land immediately after treatment. We hypothesized the development and survivorship of horn fly Haematobia irritans (L.) larvae feeding on manure resulting from these animals would not be impacted due to the p...
متن کاملWhite Eye Color Mutant in Haematobia irritans (Diptera: Muscidae)
The wild-type eye color of the horn ßy, Hematobia iritans (L.) (Diptera: Muscidae), is a dark reddish brown. An apparent spontaneous mutation in a single adult colony ßy resulted in a white-eyed mutant. A colony of white-eyed horn ßies was established from this single individual and has beenmaintained in the laboratory. Laboratory crosses determined that thewhite-eyed phenotype is inherited as ...
متن کاملDynamics of Haematobia irritans irritans (Diptera: Muscidae) infestation on Nelore cattle in the Pantanal, Brazil.
From June 1993 to May 1995, horn fly counts were conducted twice a month on untreated Nelore cattle raised extensively in the Pantanal. Horn fly population showed a bimodal fluctuation and peaks were observed every year after the beginning (November/December) and at the end (May/June) of the rainy season, which coincided with mid-late spring and mid-late fall, respectively. Horn flies were pres...
متن کاملSusceptibility of the horn fly, Haematobia irritans irritans (Diptera: Muscidae), to insecticides in Brazil.
Since horn fly populations became established throughout Brazil, complaints regarding control failure have increased around the country. A broad survey to evaluate the susceptibility of horn flies to both organophosphate (OP) and pyrethroid insecticides was conducted from October 2000 to April 2003. Bioassays using filter papers impregnated with cypermethrin, permethrin or diazinon were conduct...
متن کاملEffect of diflubenzuron on immature stages of Haematobia irritans (L.) (Diptera: Muscidae) in Uberlândia, State of Minas Gerais, Brazil.
Horn fly immatures were raised in media containing different concentrations of diflubenzuron in order to verify their susceptibility to this insect growth regulator (IGR). The 50% and 95% lethal concentrations of diflubenzuron for the population (LC50, LC95) were determined as well as the effect of this IGR on the different immature horn fly stages. The tests were performed using the progeny of...
