So, if it was actually 5 cm long, a female P. californicus is a pretty good candidate. Heavy Prionus infestations can cause wilting, yellowing, and the death of one or more bines or the entire plant. The members of this genus are large (25-70 mm) and usually brown or black. Mites are tiny arthropods, measuring less than 1/60, Trees that are under stress or that have bark wounds are most susceptible to attack by Pacific flatheaded or flatheaded appletree borers Mature trees are not usually killed, but borer activity can weaken trees or contribute to eventual death. While they look scary, adult beetles do not bite or harm humans. The younger larvae begin feeding on smaller diameter roots and ultimately reach the tree crown as mature larvae as they move inward and upward along larger roots. Herbicide Control: Imox herbicide and a surfactant will effectively control bulrush. Adults live about 4 weeks, and do not feed. Entomol. In cherries, a greater proportion of the larvae found at the crown were large, mature larvae, while most of the smaller, younger larvae were found in roots. insect whose larva feed on the roots of a variety of trees and shrubs-- The field biology and damage impact of P. imbricornis and P. laticolis in Georgia are well-known (Payne et al 1975, 1976).
