Phytoseiidae predating thrips
The sex-ratio of was in favor of females at all tested temperatures and remained uninfluenced by temperature in the range of 15–35°C with an average of about 75% females.
The lower temperature threshold for the entire development period and the thermal constant for female using the common linear model were estimated to be 11.1°C and 200 degree-days (DD), and 10.8°C and 204 DD using the Ikemoto and Takai model.
Egg, larva, protonymph, and deutonymph stages took 3.8, 1.3, 1.7, and 2.0 days, respectively, and adults survived for 19.4 days.
Within 2 days after emergence of the adults, mating took place, each copulation lasting only 7-8 min.
This is the first registered and investigated case of invasion, acclimatization and inclusion biocoenosis as an equal right member for mites of the family Phytoseiidae.
It is considered as an example of unpremeditated introduction of a beneficial predating mite together with transported plants. in southern British Columbia (Acarina: Phytoseiidae). Notes on the occurrence of Typhlodromus and Phytoseius spp. The predatory mites were kept under laboratory conditions on excised, mite-infested rose leaves.Under winter conditions (T-min 0.5-5.9 °C, T-max 18.4-22.7 °C, 20-91% relative humidity), the predatory mite completed egg-to-adult development in 8.8 days.
