Explanation:
Detailed explanation-1: -Insertion of sucking mouthparts into plants increases potential for the transmission of plant disease organisms. Sucking insects, such as leafhoppers moving among plants can transmit mycoplasma-like organisms that cause Peach X-disease and aster yellows. Aphids and leafhoppers transmit viruses to plants.
Detailed explanation-2: -Insect mouthparts are of two main types: chewing and piercing-sucking (Figure 3). Some insects have modifications of these two basic types. Mouthparts determine how an insect feeds and therefore play a role in the type of insect control that is most effective.
Detailed explanation-3: -Aphids are soft-bodied insects that use their piercing sucking mouthparts to feed on plant sap.
