Abstract
Control of the green scale by insect predators and parasites during the summer and fall months was observed to be practically nil and was considered of little importance. The twice-stabbed ladybeetle, Chilocorus bivulnerus Muls., was seen eating four green scale adults and two other species of ladybeetles were sometimes observed on foliage infested with the scales. Several species of internal dipterous and/or hymenopterous parasites and a predaceous thrips were infrequently encountered during the examination of the green scales. At least two species of mites were often observed mingling with the green scale crawlers and eggs underneath the adult scales, but they did not appear to be harmful to them. Less than 3 percent of all green scales examined were killed by their insect enemies in the summer and fall months.
