Answer

Brief Explanations:

r - selected species produce many offspring quickly and have shorter - lived generations. K - selected species have fewer offspring and longer - lived generations. Scale insects, as r - selected species, likely had a resistant strain among their large number of young. The lacewing predators, being K - selected, take longer to produce a resistant variety, so they were more affected by the spray.

Answer:

the scale insect was r - selected and the high number of young included a resistant strain, the predator was K - selected and will take longer to produce a resistant variety
