Jh. Pruett et Se. Kunz, THERMAL REQUIREMENTS FOR HYPODERMA-LINEATUM (DIPTERA, OESTRIDAE) EGG DEVELOPMENT, Journal of medical entomology, 33(6), 1996, pp. 976-978
This study was designed to define lower thermal limits for common catt
le grub, Hypoderma lineatum (Villers), egg development. The data colle
cted in this study suggest that embryonic development was prolonged as
temperature was lowered. No hatch was observed when eggs were incubat
ed at a constant temperature of 20 degrees C. Measurements of cattle s
kin temperature and ovipositional behavior of the gravid female fly su
ggest that eggs are oviposited in a suitable thermal environment for s
uccessful embryonic development. Eggs oviposited on cattle held in an
unheated barn hatched within 1 wk confirming that cattle can be succes
sfully laboratory infested in unheated barns during winter in central
Texas.
