Phytoseiidae predating thrips datingand love net
Predators were released at a rate of 4–5 individuals per plant as soon as thrips were detected on host plants.
In both years plot size consisted of 3 rows of 40 plants for each predator release and non-release control plots. This might be due to an allowance of plant characteristics to the predator to prey more efficiently.
Marcelino Typhlodromus occidentalis predator mite (Mesostigmata: Phytoseiidae) used for control of spider mites, namely, Tetranychus urtica on different crops and ornamentals (Figure 10).
In Hungary, both of these polyphagous thrips species frequently cause severe damage in many greenhouse crops, especially in commercial sweet pepper.The Phytoseiidae are therefore very important in the biological control (whether natural or humanly-instigated) of such pests.Most species can easily be reared in large numbers in the laboratory and several are in international commerce (for instance, Bio Bee in Israel (at Abstract: Biological control of Thrips tabaci was studied on greenhouse grown cucumbers by using predatory mite, Amblyseius cucumeris. Immature populations of thrips reached to a peak of about 260/leaf in non-release control plots but never exceeded 160/leaf on cv. In all plots age distribution of thrips populations were similar (85–90 % immatures, 10–15 adults), however the low numbers of immatures in predator release plots indicated that predation was heavier on immatures. In both years predator was able to bring thrips populations down to low levels. Adult populations of thrips were also higher in control plots compared to predator released plots.
