[heterotylenchus simplex sp. n. (nematoda, sphaerulariidae)--a parasite of the zoophilic fly morellia simplex lw].	a new species of nematodes, heterotylenchus simplex spn n., was found in zoophilous flies of morellia simplex caught from cows in the bakhchisaray region of the crimea. the above species differs from all known ones of the genus heterotylenchus in the presence of the quadricolumella in parthenogenetic females and rudiment of the posterior uterine branch in gamogenetic females. h. simplex is close in its biology and ecology to h. autumnalis and in its morphology - to h. aberrans.	1975	124843
aspects of the reproductive biology of some cattle-visiting muscidae (diptera) in north-east england.	during studies of flies that visit farm animals in north-east england, samples of muscidae were obtained on a regular basis from grazing animals (mainly cattle) and from manitoba traps. female flies were examined to determine their wing length, degree of wing damage, whether or not they had mated, whether their crop or gut contained blood, the stage they had reached in ovarian development and the number of eggs present. this information was used to assess the timing of mating, the stage at which ...	1985	4082443
insecticidal ear tags and sprays for the control of flies on cattle.	ear tags containing 8.5 per cent w/w cypermethrin gave almost complete control of the biting muscid, haematobosca stimulans. protection afforded against nuisance flies was more variable; generally a 70 to 80 per cent reduction of headfly, hydrotaea irritans, and a 60 to 70 per cent reduction of morellia simplex. ear tags containing 8.5 per cent fenvalerate also gave significant protection against biting and nuisance flies. spraying with 500 ppm cyhalothrin or 1000 ppm cypermethrin afforded compl ...	1984	6474773
flies associated with cattle in south west scotland during the summer months.	the sheep headfly, hydrotaea irritans, and morellia simplex were the species most frequently associated with cattle at pasture and comprised 69.01 per cent and 13.93 per cent, respectively, of the total fly collection made from grazing cattle. the most prevalent biting fly was haematobosca stimulans which comprised 4.46 per cent of the total catch. a few clegs, haematopota pluvialis, and horse flies, hybomitra distinguenda, were also recorded. a few of the headflies swarming around cattle entere ...	1981	7244374
