108
where do. you find larva for Oestrus ovis
in nasal passages of sheep
109
false gid is caused by
nasopharyngeal myiasis that has traveled to the brain of Oestrus ovis larvae
110
--- are larva with ventral spines and a smooth dorsal surface
Oestrus ovis- cause false gid and nasopharyngeal myiasis
111
how to manage myiasis
remove larva treat wounds with with antibiotics and repellants Many are susceptible to insecticide/anthelmintics eg. dichlorvos, trichlorfon. Also, ivermectin, esp. in fall, to kill early migrating larvae Modified farm practices such as dehorning Biocontrol by use of sterile male flies
112
--- Infestations may result when foodstuffs contaminated with eggs or larvae of muscoid flies are ingested or when flies oviposit on perianal skin and migrate into rectum.
enteric facultative or accidental myiasis
113
--- are used as surgical maggots.
Phaenicia serricata (Fam. Calliphoridae) cause facultative cutaneous myiasis Feed on necrotic tissues and secrete a bacteriacidal compound called allantoin
114
--- are superficially like honey bees in appearance (somewhat smaller).

115
--- are the primary Screw Worm
Traumatic myiasis - Cochliomyia hominivorax attracted to wounds- larva penetrate tissues in heads down position
116
--- Larvae have characteristic spiracular plates and spiny cuticular armature
Hypoderma bovis- warble fly bee like appearance heel fly or gad fly
117
--- larva are cattle grubs
Hypoderma lineatum- warble fly bee like appearance
118
Gait of infested sheep characterized by lifting fore feet in pawing motion, incoordination, ataxia and other nervous signs (condition called “----”), occurs when larvae gets to the frontal sinues.
False gid caused by Nasopharyngeal myiasis of Oestrus ovis (sheep bots), also Rhinoestris purpureus (head maggots of horses).
