Project title
Establish a correlation between the degree day model, pheromone trap catches and physical vine monitoring of grapevine mealybug

Project leader
Achiano, K A

Project description
The mealybug, Planococcus ficus in the vine growing regions has the potential to become resistant to conventional sprays. Mealybug infestation is one of the most serious problems for vine growers and is considered as the major vector of grapevine leafroll virus and corky bark diseases. Apart from this, it causes direct damage by its feeding and honeydew secretions. The presence of mealybug on exported table grapes may lead to rejection of consignments. The present study is to find out how the female mealybug infestation through vine inspection, male pheromone trap catches and coupled with the degree day model can be combined to attain a more effective control of grapevine mealybug.
