Parasitism by the mite Acarophenax lacunatus on beetle pests of stored products
BioControl 48 (5), 503-513
Abstract: Recent reports of the biocontrol potential of the mite species Acarophenax lacunatus (Cross and Krantz) (Prostigmata: Acarophenacidae) and the lack of biological studies on this regulatory agent led to the present study carried out under laboratory conditions. The objective of the investigation was to assess the host range of A. lacunatus, so far only reported as egg parasite of Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae). Four Coleoptera species of stored cereals were used: R. dominica, Tribolium castaneum (Herbst) (Tenebrionidae), Cryptolestes ferrugineus (Stephens) (Laemophloeidae) and Oryzaephilus surinamensis (L.) (Cucujidae). The highest rates of egg parasitism were observed on R. dominica and T. castaneum, leading to a significant decrease of populations of both species and reduced wheat weight loss. A. lacunatus was also able to parasitize eggs of C. ferrugineus, but not of O. surinamensis. These results indicate a broader host range of A. lacunatus than initially suspected and also strengthen its possibility of use in integrated pest management programs in storage environments.
