Entomologist Joseph Dickens and his colleagues in the Invasive Insect Biocontrol and Behavior Laboratory discovered that a taste receptor located on a mosquito mouthpart
is sensitive to DEET.
Most true bugs, such as spittlebugs and aphids, use this tough mouthpart
to pierce plants and drink their sap or other juices.

Parasitic nematodes have a specialized mouthpart
called a stylet that allows them to pierce their prey in order to extract nutrients (though the size of the stylet varies between the different parasitic nematode genera).
Intraoperatively, the tick was alive, its abdomen was distended, and its mouthpart
was embedded in the tympanic membrane near the umbo.
No animals were dissected to identify deformities of the mouth or internal organs and no tadpoles were assessed for mouthpart
abnormalities or other deformities.

MORPHOLOGY IN LARVAL CHIRONOMUS RIPARIUS (DIPTERA: CHIRONOMIDAE).
The scale uses its piercing-sucking mouthpart
, known as a stylet, to penetrate the thin bark of the beech, and then it feeds on the living cells within.
Their long proboscis, or mouthpart
, makes them important pollinators, since many plants may only be pollinated by hawkmoths.
The study found that, unlike other African hooved mammals living in the same areas as zebras, zebra hair is shorter than the mouthpart
length of biting flies, so zebras may be particularly susceptible to annoyance by biting flies.
In the mouthpart
tests, taste nerves in honeybees and buff-tailed bumblebees showed no jolt of reaction to three neonicotinoid pesticides, says Geraldine Wright of Newcastle University in England.
A wet sippy cup mouthpart
was left on each surface including a high chair, tile floor, carpet, countertop and table, for 5 seconds.
