Hemlock woolly adelgid is an insect pest to hemlock trees. it was introduced in the united states during the 1920's. it is not native to the united states and has few natural predators. to control this insect pest, scientists identified a species of predatory beetle, (pseudoscymnus tsugae ( they hope to introduce this beetle to reduce the woolly adelgid population, and minimize the damage caused to hemlock trees. each pt larva eats about 500 eggs or 50 -100 immature adelgids. females lay up to 300 eggs in march and april, during peak egg- laying of hemlock woolly adelgid. the beetles have a second generation in june around the same time as the second adelgid generation. adult pt feed on dormant young adelgids during the summer. 176,387 beetles have been released at 50 sites in 23 counties. which of these questions best summarizes the research described?
