Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae). The harmful species evaluated as prey were the root-knot nematode, Meloidogyne javanica (Heteroderidae), the gastrointestinal sheep-parasitic nematode, Haemonchus contortus (Trichostrongylidae), the bulb mite, Rhizoglyphus columbianus (Astigmata: Acaridae) and the sciarid fly, Bradysia matogrossensis (Diptera: Sciaridae). Additionally, five species were tested as potential alternative food sources for the mass rearing of predators: eggs of Ephestia kuehniella (Lepidoptera: Pyralidae), the mites Glycyphagus destructor (Astigmata: Glycyphagidae), Thyreophagus cracentiseta and Tyrophagus putrescentiae (Astigmata: Acaridae), and the free-living nematode Rhabditella axei (Rhabditidae). Daily predation rates (by female) between the predators did not differ when M. javanica was offered (congruent to 240-245 second-stage juveniles). For H. contortus, G. lavafesii exhibited a higher daily predation rate (congruent to 204 third-stage juveniles), whereas C. mediocuspis showed higher daily consumption of R. columbianus (congruent to 6.1 larvae/nymphs) and B. matogrossensis (congruent to 1.5 larvae). The highest oviposition rate of G. lavafesii (3 eggs/female/day) was observed on M. javanica, while C. mediocuspis laid at most 0.6 eggs/female/day on all evaluated prey. For large-scale rearing, R. axei provided the best oviposition rate for G. lavafesii (8 eggs/female/day), whereas the highest rate for C. mediocuspis was obtained on E. kuehniella eggs (1.3 eggs/female/day). These findings will provide valuable insights for developing new biological agents for harmful organisms that spend part of their life cycle in the soil. (AU) | |
