| abiotic factors influencing embryonic development, egg hatching, and larval orientation in the reindeer warble fly, hypoderma tarandi. | wild-caught, tethered females of the reindeer warble fly, hypoderma tarandi (l.) (= oedemagena tarandi (l.)), (diptera, oestridae) were stimulated to oviposit on hairs of a reindeer hide. newly laid eggs incubated at constant temperatures and relative humidities hatched within 3 days to 2 weeks, depending on the experimental conditions. over a range of 7-40 degrees c, hatching only occurred between 20 and 37 degrees c. eggs held at 100% relative humidity had lower hatchability and longer time to ... | 1992 | 1463901 |
