Chapter 12.4, Problem 1TQ

Summary Introduction

To review:

The following: 

1. The importance of considering the effects of developing insect resistance to an insecticidal plant before developing a transgenic crop.

2. The process of designing the transgenic plants to limit the possibility of insects developing resistance.

Introduction:

The ability of insects to resist the effect of an insecticide to which they were once sensitive is called insecticidal resistance. Resistance can be developed by many factors. Few individuals in the population of insects may carry the genes for resistance. Upon exposure to insecticides, the insects carrying the resistant genes are favored by nature and outbreed the insects that do not carry resistant genes.
