“…The most abundant species were Ueckermannseius macrosetosus (van der Merwe), Amblyseius herbicolus (Chant), Typhlodromips culmulus (van der Merwe) and Euseius rhusi (van der Merwe) presenting over 80% of the total phytoseiid fauna collected from the farms. The tea canopy was found more compact than that of cassava which was recently found to host 29 species of Phytoseiidae Family where Typhlodromalus aripo (De Leon) and Euseius fustis (Pritchard & Baker) led by 71% of the field sample frequency (Molo et al 2016;Mutisya et al, 2017).…”

Tea agro ecosystems are least disturbed in comparison to other crop systems due to the plant canopy type. A survey on predacious mites’ abundance and impact on leaf yield in different tea production areas was carried out in 2014-2015 in Kenya. Major pest species were the red spider mite Oligonychus coffeae and the yellow thrip, Scirtothrips dorsalis. The red crevice mite, Brevipalpus phoenicis was found in few areas and in low numbers. Predacious mites of Phytoseiidae Family were highest at 5.8 and 6.8 mites per sample during dry and wet seasons, respectively. Phytoseiid abundance during the dry and wet seasons did not differ much within most sample sites. Presence of phytoseiid mites in combination with NPK-fertilizer-high altitude led to the strongest correlation to leaf yield than any other combination variable. High phytoseiid density- high altitude was third with positive impact to yield increase after high altitude combined with NPK-fertilizer. The findings here show contributory positive impact of phytoseiids in tea leaf yield in an agro eco-system.

“…Considering T. urticae biological potential for fast colonization of plant species and the optimum conditions in existence in places where Brachiaria grass is grown, high damage levels will continue to be experienced in specific warm localities in Kenya. An approach of suppressing mite damage would encompass the manipulation of pasture production field conditions and an integration of the biological and cultural techniques as applied in cassava [19,25].…”
