Question 2
Look at the pictures below.
Based on the picture above, there are two species of ladybug. The ratio between species M and species W per m² is 4 to 1. Species W does not have resistance gene on their DNA, while species M has resistance gene on their DNA. These insects typically have a lifecycle of a few days to a few weeks.
Questions:
a. (1 point) What will happen if “ABC” insecticide is used in a long period to those insect population?
b. (2 point) How should we use insecticide to prevent the resistance effect?
c. (1 point) After the “ABC” insecticide usage was banned and people never use insecticide, predict the ratio of two ladybug species.
d. (3 point) Draw a pattern of the amount of two species population before and during the use of insecticide, and also after it was banned in the diagram on the ANSWER SHEET.
