چکیده
In Australia, sweetpotato (Ipomoea batatas L.) is vulnerable to root feeding insect pests such as wireworms (e.g., Agrypnus spp.). The number of registered insecticides control these limited and often pest pressure, for example by wireworms, severe close harvest, further limiting what can be applied. Incorporating biological agents entomopathogenic fungi Metarhizium anisopliae) into integrated management programmes may feasible in sweetpotato. M. anisopliae has been shown effective controlling more than 200 insects it able reside grow the rhizosphere rhizoplane, suggesting that could a promising candidate against soil pests. study presented here, was formulated calcium alginate granules fortified with nutrients. resporulation fungal tested on four different types laboratory. biocontrol efficacy resulting growth also examined using larval mealworms, Tenebrio molitor model laboratory glasshouse. Our results indicated sterilised favoured optimal resporulation, although did not have significant effect resporulation. caused high mortality (up 76%) mealworms glasshouse, whereas applied non-sterile demonstrated poor led low (13%) mealworms. result this indicates manipulation microbial populations field required enhance potential field.
