Story: Insect pests of crops, pasture and forestry

Resistant and non-resistant plants

Resistant and non-resistant plants

Some plants are naturally resistant to insect pests – insects do not attack them, presumably because of their physical and/or chemical composition. Other plants are tolerant to insect attack – the pests can attack them but the plants are not affected enough to die. Others are non-resistant, so insects can attack and kill them. Ryegrass (left) is non-resistant to grass grub attack, while tall fescue (right) is tolerant to attack by grass grubs.
