Q16 If bugs did disperse what are the costs and benefits of accepting a host plant of either species? Your answer Q17 How could a dispersing bug know what species of plant it was settling on? Your answer Q18 Very briefly outline an experiment to demonstrate that a dispersing bug was able to discriminate one species of plant from another. (2-3 sentences). Your answer Q19 What would constitute a 'suitable mate for any particular bug, assuming that reproduction with a suitable mate produces high fitness offspring?

Answer 1

17.A bug will come to know about its plant host by the taste and smell.
18.Experiment: Soapberry bug generally infects ballonvine.
Experiment: A soapberry bug has to taken in a box that contains a partition. put a balloon vine plant and a rain tree plant on opposing corners on the other side of the partition. Then the partition has to be removed. If the bug is able to move towards balloon vine instead of towards raintree plant, then it can be understood that the bug is able to discriminate its host plant.
19.A suitable mate would be a bug that has a trait that would be good for survival in the current location. For example, it they are living in the balloon vine population, a suitable mate would be a bug with a beak size that is the same length of the average (or slightly more) radius of a balloon vine plant.
A suitable mate is the one, which is able make best utilisation of the plant host and does not disturb it's mate partner from its survival, instead encourages
20.The bug could look for other bugs that are successful in consuming the seed of the fruit that is abundant in that area.
21.The more generations there are, the more likely we are to seeing a response to natural selection because the favored alleles would be passed on from generation to generation and the less favored alleles would disappear over generations.
