The efficacy of a novel air stream predator mite application method for the control of twospotted mites (TSM Tetranychus urticae) in hops was compared with a standard teaspoon release method Predator mites (Phytoseiulus persimilis) were successfully established with a single release using both application methods and TSM declined to low numbers during the monitoring period Application of predator mites with a delivery device attached to a conventional leaf blower mounted on a quad bike was equally effective and at least four times faster than hand application There was no evidence of any physical damage to mites applied with the mite blower device The potential of the air stream application method to improve the efficiency of biological control of TSM using predator mites is discussed

Predatory Gall Midge

The two spotted spider mite, <em>Tetranychus urticae </em><a title="Carl Ludwig Koch" href="https://en.wikipedia.org/wiki/Carl_Ludwig_Koch">C. L. Koch</a>, 1836 is one of the most important pests of greenhouse crops worldwide. Due to its polyphagic range of hosts and rapid development it forms great populations and as such represents a suitable host/prey for lots of natural enemies usable in biological control. Most commonly used predators of Tetranychid mites are predatory mites (<em>Phytoseiulus persimilis </em>Athias-Henriot, 1957, <em>Amblyseius swirskii </em>Athias-Henriot, 1962<em> </em>,…), but among most voracious predators is the larva of a predatory gall midge, <em>Feltiella acarisuga</em> (<a title="Jean Nicolas Vallot" href="https://en.wikipedia.org/wiki/Jean_Nicolas_Vallot">Vallot</a>, 1827) that was found also in greenhouses of the Biotechnical Faculty in Ljubljana on eggplant leaves in 2017. Besides the predatory gall midge also another predator, staphylinid <em>Oligota oviformis </em>Casey, 1893<em> </em>beetles and larvae were found in great numbers. After positive identification of <em>F. acarisuga </em>found naturally in Slovenia, it can be added to the list of indigenous species of natural enemies and thus can be used in biological control programs in greenhouse crop protection against spider mites.

Two Spotted Spider Mite

The two-spotted spider mite Tetranychus urticae is a dangerous polyphagous pest of agricultural and ornamental plants. In a commercial greenhouse treated with acaricides or biological control using predatory mite Phytoseiulus persimilis individual varieties of roses differed significantly in terms of the average annual infestation by the pest mite. On the poorly populated rose varieties, the biological control agent application was more effective as compared to the acaricides. To effectively control the pest, the required predatory mite rates were 4.6–8.7 times higher on varieties with a minimal spider mite infestation (Aqua and Deep Water) as compared to the maximal pest infestation (Heaven and Brazil).
