Biology and Ecology of the Buffalo Fly, Haematobia exigua de Meijere (Diptera: Muscidae
Thesis Abstract:
Under the laboratory conditions, buffalo fly eggs hatched after 17-22 hours It took 3-4 days for tje larvae to become pupae 5-7 days for the pupae to become adults. Life cycle fields was completed in 9.5-10.5 day in the laboratory and 9-14 days under field conditions. Mating usually occured on the 6th or 7th day and preoviposition, on the 8th to the 12th day. EGG production under laboratory conditon was 20-139 per female. Longevity of male nad female was 29 and 32 days , respectively.
The belll and hind legs of the carabao were the preferred habitat either during cloudly and cool sunny and warm day. When the weather wa clear anf the carabao was the shade, the flies tended to remain on the shouolder,dewlap, back and horns.
The exposure of carabao manure markedly affectef the density of the buffalo fly. The number of buffalo flies emerging from the dung increased when the manure pad wass exposed for 30 minutes and deseased upon longer exposure.
Other dominant insects inhabitating the dung were Sepsidae, Physchodidae and Muscidae. The predator were beetles of small reddish-brown ant, Pheldolegeton sp, a big black ant, Diacamma sp. (Hymenoptera); and a tephoretic mite of the family partisdae (Parasitiformes). The hymenopteran parasites were Spalangia sp and Trichoria sp.
