Studies on the biology of Argas (A.) reflexus (Fabricius, 1794) (Acari: Ixodida: Argasidae). 2. Effect of alternating temperatures on embryonic development and egg hatch.
The paper presents the results of observations on the effect of temperature alterations between 9 degrees C and 30 degrees C every 6 and 12 hours, respectively, on the embryonic development and egg hatch of Argas (A.) reflexus. No effect of the frequency of temperature changes on the percentage of egg mortality, embryo mortality, abnormal egg hatching, or egg hatching into morphologically normal larvae was observed. The experiments showed that in changes temperature have a particularly detrimental effect on the eggs prior to blastulation.
