The grownup females lay egg from fall to spring on leaf petiole , near plant life crowns , or in nearby soil .
Both grownup and larvae feed on leaves , but the majority of damage happens when the prepare tissue paper is feed upon , stunt increment . Along with said growth reduction , holes in the foliation are a primary symptom of plague .
cover vulnerable crop with fabric works for prevention , as well as carry off nearby skunk , rotating bok choy with less susceptible crop , and till up the soil after harvest home .
