Project description
Planococcus ficus, the vine mealybug, is responsible for virus transmission, direct crop loss and weakening of vines. Pesticide failures and global antagonism towards the use of chemicals necessitate research into alternative control options, such as into the inundative release of natural enemies.

Currently there is a worldwide newfound interest in entomopathogenic nematodes of the families Heterorhabditidae and Steinernematidae, as they represent biological control agents that have no adverse effect on the environment and humans. They can be mass-reared and commercially formulated. The aim of the proposed research will be to evaluate local isolates of entomopathogenic nematodes for their potential to control vine mealybug in protected places (such as under the bark of the trunk, or on spurs or canes) above ground and on the roots of grapevine in the soil. This research will evaluate the potential of local isolates of entomopathogenic nematodes as immediate and long-term control agents of the vine mealybug in an integrated pest management system in grapevine.
