Digestive α‐amylases of the flour moth Ephestia kuehniella– adaptation to alkaline environment and plant inhibitors
The digestive tract of lepidopteran insects is extremely alkaline. In the present work, molecular adaptation of amylolytic enzymes to this environment was investigated in the flour moth EphestiaExpand
Temperature-dependent population growth of three species of stored product mites (Acari: Acaridida)
The pest potential of stored product mites depends on the reproduction rate that is affected by the environmental conditions. In this study we investigated the effect of temperature, ranging from 5Expand
Point mutations in the sodium channel gene conferring tau-fluvalinate resistance in Varroa destructor.
BACKGROUND Sodium channels (SCs) in mites and insects are target sites for pesticides, including pyrethroids. Point mutations in the SC gene have been reported to change the structural conformationExpand
Suppressive Potential of Bean (Phaseolus vulgaris) Flour Against Five Species of Stored-Product Mites (Acari: Acarididae)
Abstract Previous research has demonstrated that legume proteins have insecticidal activity against stored-product pests, but activity against stored-product mites has not been tested. A study wasExpand
Mites and fungi in heavily infested stores in the Czech Republic.
Toxigenic and allergen-producing fungi represent a serious hazard to human food and animal feed safety. Ninety-four fungal species were isolated from mite-infested samples of seeds taken from CzechExpand
Comparison of tau-fluvalinate, acrinathrin, and amitraz effects on susceptible and resistant populations of Varroa destructor in a vial test
The parasitic mite Varroadestructor is a major pest of the western honeybee, Apis mellifera. The development of acaricide resistance in Varroa populations is a global issue. DiscriminatingExpand
Ultrastructure of the digestive tract in Acarus siro (Acari: Acaridida)
The gut of the mite Acarus siro is characterized on the ultrastructural level. It consists of the foregut (pharynx, esophagus), midgut (ventriculus, caeca, colon, intercolon, postcolonic diverticula,Expand
Astigmatid mite growth and fungi preference (Acari: Acaridida): Comparisons in laboratory experiments
Abstract The relationship between palatability and suitability of fungi for sustaining mite population growth was tested in the laboratory. The effect of mite fungal preference on spore dispersionExpand
Prey range of the predatory mite Cheyletus malaccensis (Acari: Cheyletidae) and its efficacy in the control of seven stored-product pests.
Abstract The prey range of the predatory mite Cheyletus malaccensis was evaluated on the basis of its population growth on various prey species under laboratory conditions. The prey species wereExpand
Differential natural performance of four Cheyletus predatory mite species in Czech grain stores
Abstract Out of four Cheyletus species occurring in grain stores in Central Europe, only C. eruditus is employed for the biocontrol of stored-pest arthropods. Unlike laboratory test data, field dataExpand
