Abstract. 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 α-amylase inhibitor acarbose is effective against the α-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. Acarbose had no negative effects on the longevity and the length of oviposition period of C. malaccensis but partially reduced its fecundity. The results are discussed in the context of the integrated control of stored-product mite pests. 相似文献

SUMMARY. Gregarines were found for the first time in the honey bee Apis mellifera L. in Venezuela. The parasites attacked the inner wall of the ventriculus of the adult bees, causing heavy losses in apiculture in October 1954 and June 1955. The disease produced was called gregarina disease of the honey bee (in Spanish "gregarinosis de la abeja"). 相似文献
