Presentation by Silvia Rondon on Insect Ecology. Topics covered include types of metamorphosis, effects of temperature on development, how temperature affects SWD and potato tuberworm.
Q: I have been manually trying to dig this plant up in my yard and it keeps coming back. Does it respond to salt/vinegar treatment or burning? It seems to put out a lot of bulbs and tubers and is in several parts of my yard. I don't like using chemicals in my yard, so that isn't an option.
Q: What do you recommend for keeping weeds at bay in planting beds? We'd like to stop using Round-Up. Our beds are too big and the weeds are too numerous to be able to keep up mechanically. Would a vinegar solution be harmful to the soil?
Q: I have a plot in a community garden in Portland, on a hill. Last year my corn didn't fully mature. I'd like to try planting the 3 sisters this year; corn, beans, and gourds. I would like planting advice.
