Combined effect of an antifeedant -amylase inhibitor and a predator Cheyletus malaccensis in controlling the stored-product mite Acarus siro
2007
Acarus siro is the most abundant and frequent mite to infest
stored-food products, causing allergies and transmitting
mycotoxin producing fungi. The predatory mite Cheyletus
malaccensis is a candidate species in the biocontrol programme
for this pest. In vitro, the a-amylase inhibitor acarbose is
effective against the a-amylase of A. siro but not against that
of C. malaccensis. In vivo, the impact of acarbose on a
population of A. siro is investigated along with the
interaction with the predator. Various densities of adult
parthenogenetic females of C. malaccensis are reared on A. siro
feeding on either a control diet or a diet containing different
acarbose concentrations. The combined action of both factors
significantly improved the final biocontrol efficiency with C.
malaccensis, compensating for the lower energetic content of
the prey on acarbose by increasing the number of prey caught.
