Phenology of T. elegans

The appearance of the life stages of T. elegans in various seasons was analyzed on the basis of

7,190 samples ( Table 2). The peak of the abundance of T. elegans occurs in June ( Figure 16 ).

of total samples, Nsp – Number of positive samples (with T. elegans ), N – Total number of specimens,

F – Female, M – Male, D – Deutonymphs, P – Protonymphs, L – Larvae.

The number is also high in samples collected in May and August. However, it was very low at the beginning of the phenological season in April and the end of it (December).

The constant presence of adults and deutonymphs in the collected samples was recorded between April and October ( Table 2). Single male specimens were found in December, which suggests that these mites overwinter as adults and deutonymphs hidden under bark of trees. Unfortunately, we do not have enough samples collected in winter to support this hypothesis. The diagram shows ( Figure 16 ) that the presence of larvae and protonymphs is limited in time and has two peaks of abundance, i.e. the first in June and the second in October. The larvae were found in May, September, and October, whereas the protonymphs occurred between May and August, and in October.
