Effect of diets and temperature degrees on the biological aspects of the Laelapid mite, Ololaelaps Ussuriensis Bregetova & Koroleva, 1964 [electronic resource].

Includes references.

The biological aspects of the laelapid mite, 0/o/ae/aps ussuriensis (Laelapidae: Mesostigmata) was investigated at laboratory conditions under different diets and two temperature degrees. The obtained results showed that the diets as acarid mite , Tyrophagus putrescentiae (Schrank) and free living nematodes, Rhabditella muscicola (Andrassy) and temperature degrees (15 and 25 °C} were significantly influenced the periods of incubation period, longevity and life span of the predatory mite, 0. ussuriensis, but there was no significant differences in the case of combination or interaction between these factors .Data , also, indicated that the adult female of 0. ussuriensis laid more eggs (41.8 eggs) when fed on the free living nematode at 25 °C compared with the acarid mite diet . The lowest number of laid eggs (33 eggs) was observed when the females fed on T. putrescentiae at 15 °C.
