Males cannibalise and females disperse in the predatory mite Phytoseiulus persimilis Exp. Appl. Acarol. (IF 1.532) Pub Date : 2020-09-26 Alexandra M. Revynthi, Kaya E. van Pol, Arne Janssen, Martijn Egas
Cannibalism is a widespread phenomenon in nature, often occurring when food is scarce, for example among predators that have overexploited a local prey population. Instead of cannibalising, predators can disperse, thereby avoiding being cannibalised or cannibalising related conspecifics, which results in inclusive fitness loss. Theory on prey exploitation in ephemeral predator-prey systems predicts

Ecology of Antricola ticks in a bat cave in north-eastern Brazil. Exp. Appl. Acarol. (IF 1.532) Pub Date : 2020-09-12 Eder Barbier,Enrico Bernard,Filipe Dantas-Torres
Argasid ticks are a diverse group of acarines that parasitize numerous vertebrate hosts. Along with birds, bats serve as hosts for several argasid ticks, which are commonly found in bat caves. Argasid ticks have regained attention from tick taxonomists in recent decades, with a number of new species described in various zoogeographical regions. Nonetheless, studies on their ecology are still scarce

Inventory of Varroa destructor susceptibility to amitraz and tau-fluvalinate in France. Exp. Appl. Acarol. (IF 1.532) Pub Date : 2020-08-18 Gabrielle Almecija,Benjamin Poirot,Précillia Cochard,Christelle Suppo
Varroa destructor is one of the greatest threats for the European honeybee, Apis mellifera. Acaricides are required to control mite infestation. Three conventional chemical acaricide substances are used in France: tau-fluvalinate, flumethrin and amitraz. Tau-fluvalinate was used for over 10 years before experiencing a loss of effectiveness. In 1995, bioassay trials showed the first mite resistance
