Insects have ability to resist insect damages naturally or through genetic engineering.

1. Insect resistance

2.  Developed ability of insects to tolerate doses of
toxicants is insect resistance.

3. Insect have ability to resist from damage naturally
or through genetic engineering.

4. • Some plant produce toxic compounds to insects
& some insects are able to make resistance to
them.
• Resistance arises because of the over use or
misuse of an insecticide.

5.  Insect have natural resistance genes &
genetically modified resistance genes
for plant toxins & insecticides.

6. When apply the insecticides,
1) Kill susceptible insects.
2) Survive resistance insects & some susceptible
insect that escape from the insecticide spray.
3) Reproduce resistance insects.
4) Amount of the resistance individuals is higher in
the next generation.

8.  Only few individuals carry the resistance genes.
 These genes arise from mutations & these are
rare.
