Effect Of Temperature On Hyalomma (Hyalomma) Impeltatum Schulze And Schlottke (Ixodoidea: Ixodidae)
منشور في 1988"…Also, the percentage loss in weight by larvae before feeding and during molting and by nymphs and females before feeding was not affected by temperature but nymphal loss in weight during molting was greater at 34°C than at 21-29"C. Fifty percent of the egg masses were deposited within 7.9, 6.8, 4.6 and 4.2 days, and 90% within 20.0, 18.0, 11.6 and 9.3 days at the tested temperatures, respectively. …"
