  • Title: Effect of temperature on transtadial transmission of Theileria annulata in Hyalomma anatolicum anatolicum ticks.
    Author: Das SS, Sharma NN.
    Journal: Vet Parasitol; 1991 Oct; 40(1-2):155-8. PubMed ID: 1763485.
    Abstract:
    The effect of temperature on the transtadial transmission of Theileria annulata in Hyalomma anatolicum anatolicum was studied. Variation in temperature (4-40 degrees C) had a significant effect on moulting rate of the ticks and transmission of theilerial parasites from nymphs to resultant adults. The temperatures above 40 degrees C and below 12 degrees C prevented moulting. Maximum infection levels were obtained in salivary glands of adult ticks when the infected engorged nymphs were incubated at 24-28 degrees C. The infection rate in salivary glands was assessed using a methyl green pyronin technique.
