Metamorphosis and Gonad Maturation in the Horn FlyHaematobia irritans [PDF]

Journal of Insect Science, 2011
The bloodsucking horn fly, Haematobia irritans (L.) (Diptera: Muscidae), is one of the most damaging pests of pasture cattle in many areas of the world. Both male and female imagoes spend their adult stage on the host, while immature stages develop in dung. Our goal was to determine if the progress of H. irritans gonad maturation can be correlated with
