Abstract:Dales when larvae of whitefringed beetles were introduced into the soil directly influenced the rate of larval development and, therefore, the capacity of larvae to reduce stands of rye and soybeans. 'Vet weights of rye, harvested from plots infested with newly hatched larvae in July. were significantly less than those of plots infested in August and September. Seedling numbers of soybeans planted in April in plots infested the previous July and August were significantly less than numbers in plots infested the previous September. Seedling numbers of soy- beans planted in May in plots infested in August were significantly less than numbers in plots infested in July and September. Data suggest the need for preventive adulticidal treatments during critical ovipositional periods to reduce the establishment of larval populations.
