Specimens examined: Muoi in P8 plot (aasl 66 m, lat. 21°54’46” N, long. 104°38’9” E), 1 ♀ on Paspalum sp. ( Poaceae ), 17/V/2017.

Remarks: Amblyseius herbicolus is widespread in all tropical and subtropical regions of the world. It is the second most abundant phytoseiid mite Coffea on arabica in Brazil, and is deemed to be an efficient predator of Brevipalpus phoenicis (Geijskes) , vector of the coffee ring spot virus ( Reis et al. 2007). Amblyseius herbicolus is also found in association with the broad mite, Polyphagotarsonemus latus Banks in crops such as chili pepper ( Capsicum annuum ) in Brazil and has good potential for controlling the latter. Rodriguez-Cruz et al. (2013) have demonstrated that A. herbicolus was able to develop on broad mites, castor bean pollen ( Ricinus communis ) and sunn hemp pollen ( Crotalaria juncea ). Provision of pollen can enhance populations of this predator and increase biological control ( Duarte et al. 2015), especially with cattail pollen ( Typha latifolia ), chilli pepper pollen and bee-collected pollen. Amblyseius herbicolus was collected recently in Comoros archipelago ( Kreiter et al. 2018b).

This is the first record of that species in Vietnam.

Measurements of the single specimen collected during this study are provided in table 8 and compared with measurements obtained from specimens collected in other countries of Africa, Asia and Indian Ocean. These measurements match with those obtained previously. The dorsal shield width is less important in the single Vietnam specimen than all order widths of the table, probably because the single female was a small one, all other dimensions being quite similar.
